The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 2A is a flowchart illustrating a resource control method according to an embodiment of the present application. As shown in fig. 2A, the method of the embodiment of the present application may include:
step S201, acquiring a use state of at least one hardware device resource.
In this step, the resource control apparatus may obtain an available manner of the use state of the at least one hardware device resource, which at least includes the following manners:
the first realizable way: the resource control device may detect the usage status of at least one hardware device resource every a preset duration. Optionally, the specific detection manner may refer to a detection manner in the related art, which is not limited in the embodiment of the present application.
The second realizable way is as follows: the resource control apparatus may determine the usage status of the at least one hardware device resource according to the received resource request information (carrying the identifier of the requested hardware device resource) and/or the resource release information (carrying the identifier of the released hardware device resource) sent by the at least one resource device service.
Exemplarily, if it is known that any hardware device resource is currently allocated to a multimedia service and resource request information (carrying an identifier of the hardware device resource) sent by other multimedia services except the multimedia service is received, the resource control device determines that the usage state of the hardware device resource is switched from the allocated state to a collision state (that is, the hardware device resource is a collided device resource).
Of course, the resource control apparatus may also obtain the use state of at least one hardware device resource through other realizable manners, which is not limited in this embodiment of the application.
Step S202, if the use state of any hardware equipment resource is switched to a conflict state, switching the hardware equipment resource in the first resource equipment service to a software equipment resource corresponding to the hardware equipment resource, and reallocating the hardware equipment resource to a second resource equipment service;
the first resource device service belongs to a first hardware channel corresponding to a first multimedia service which is currently operated; the software device resource is used for carrying out logic processing on an output signal of an upstream resource device service of the first resource device service in the first hardware channel; the second resource device serves a second hardware path corresponding to a second multimedia service to be operated.
In this step, if the usage state of any hardware device resource is switched to the conflict state, the resource control device switches the hardware device resource in the first resource device service to the software device resource corresponding to the hardware device resource (i.e., the usage state of the hardware device resource is switched to the idle state), so that the software device resource corresponding to the hardware device resource performs the logic processing corresponding to the hardware device resource on the output signal of the upstream resource device service, so that the processing logic of the upstream resource device service (or the upper layer resource device service) is not affected, and the upstream resource device service is located upstream of the first resource device service in the first hardware path.
Further, the resource control device reallocates the hardware device resource to the second resource device service currently requesting the hardware device resource (i.e. the usage state of the hardware device resource is switched to the allocated state), so as to facilitate the operation of the second multimedia service.
It can be seen that, when a hardware device resource conflicts, the resource device service (such as the first resource device service) to which the hardware device resource currently belongs is switched to a software operating mode, and the hardware device resource is allocated to the resource device service (such as the second resource device service) that currently requests the hardware device resource, so that the problem of hardware device resource conflict is solved, and the operation of the current multimedia service (such as the first multimedia service) is not interrupted.
Fig. 2B is a first schematic structural diagram of a first hardware path provided in an embodiment of the present application, fig. 2C is a second schematic structural diagram of the first hardware path provided in the embodiment of the present application, and fig. 2D is a second schematic structural diagram of the second hardware path provided in the embodiment of the present application. The explanation of step S202 is made with reference to fig. 2A to 2D:
as shown in fig. 2B, it is assumed that the first hardware path corresponding to the currently running first multimedia service initially includes: a third resource device service, a first resource device service, and a fourth resource device service, and each resource device service operates in a hardware operating mode (e.g., a third resource device service control module in the third resource device service is connected to the third hardware device resource, a first resource device service control module in the first resource device service is connected to the first hardware device resource, and a fourth resource device service control module in the fourth resource device service is connected to the fourth hardware device resource).
As shown in fig. 2C, when the second resource device service that acquires the second multimedia service also requests the first hardware device resource (that is, the usage state of the first hardware device resource is switched to the conflict state), the resource control apparatus switches the first hardware device resource in the first resource device service to the first software device resource corresponding to the first hardware device resource.
Further, the resource control apparatus reallocates the first hardware device resource to a second resource device service currently requesting the first hardware device resource. As shown in fig. 2D, the second hardware path corresponding to the second multimedia service includes: a fifth resource device service, a second resource device service, and a sixth resource device service; a fifth resource device service control module in the fifth resource device service is connected to the fifth hardware device resource, a second resource device service control module in the second resource device service is connected to the first hardware device resource, and a sixth resource device service control module in the sixth resource device service is connected to the sixth hardware device resource.
For convenience of understanding, the following embodiments of the present application describe a specific implementation manner of "switching the hardware device resource in the first resource device service to a software device resource corresponding to the hardware device resource":
illustratively, the resource control device records the status characteristic information of the hardware equipment resource; further, the operation of the hardware device resource is stopped, and the software device resource is configured according to the state feature information, so that the software device resource performs logic processing corresponding to the hardware device resource on an output signal of an upstream resource device service served by the first resource device in the first hardware path.
In this embodiment, the resource control apparatus records the status characteristic information of the hardware device resource (e.g., the first hardware device resource in fig. 2B or fig. 2C), so as to subsequently configure the software device resource (e.g., the first software device resource in fig. 2B or fig. 2C) corresponding to the hardware device resource and/or subsequently recover the configuration of the hardware device resource (i.e., recover to allocate the hardware device resource to the first multimedia service). Further, the resource control device stops the operation of the hardware device resource, so as to allocate the hardware device resource to the second resource device service in the second multimedia service. Further, the resource control device configures the software device resource according to the status feature information, so that the software device resource performs a logic process corresponding to the hardware device resource on an output signal of an upstream resource device service (e.g., a third resource device service in fig. 2C) serviced by the first resource device in the first hardware path.
It should be noted that, the execution sequence of the step of recording the status characteristic information of the hardware device resource and the step of stopping the operation of the hardware device resource is not limited, and may be other sequences (for example, the step of stopping the operation of the hardware device resource and the step of recording the status characteristic information of the hardware device resource are executed in sequence, or both of them are executed at the same time), which is not limited in the embodiment of the present application.
In another exemplary embodiment, the resource control apparatus may further switch the output end of the upstream resource device service of the first resource device service in the first hardware path from the hardware device resource to the software device resource, and switch the input end of the downstream resource device service of the first resource device service in the first hardware path from the hardware device resource to the software device resource.
In this implementation manner, on one hand, the resource control apparatus may further switch, by the hardware device resource (e.g., the first hardware device resource in fig. 2C), the output end of the upstream resource device service (e.g., the third resource device service in fig. 2C) located in the first hardware path to be connected to the software device resource (e.g., the first software device resource in fig. 2C), so that the software device resource performs corresponding logic processing on the output signal of the upstream resource device service of the first resource device service.
On the other hand, the resource control apparatus switches an input end of a downstream resource device service (e.g., the fourth resource device service in fig. 2C) located in the first hardware path from the hardware device resource (e.g., the first hardware device resource in fig. 2C) to the software device resource (e.g., the first software device resource in fig. 2C), so that the software device resource performs corresponding logic processing on an output signal of the upstream resource device service of the first resource device service to obtain a signal, and continues to transmit the signal to the downstream resource device service of the first resource device service.
It can be seen that after the hardware device resources that are conflicted in the first hardware path are allocated to the second multimedia service, the first multimedia service corresponding to the first hardware path can still continue to operate.
Of course, the resource control apparatus may also switch the hardware device resource in the first resource device service to a software device resource corresponding to the hardware device resource in other realizable manners, which is not limited in this embodiment of the application.
In the embodiment of the application, the use state of at least one hardware device resource is obtained; if the use state of any hardware equipment resource is switched to the conflict state, the hardware equipment resource in the first resource equipment service is switched to the software equipment resource corresponding to the hardware equipment resource, and the hardware equipment resource is reallocated to the second resource equipment service, so that the second multimedia service can be operated conveniently. Therefore, when the hardware equipment resource conflicts, the first resource equipment service to which the hardware equipment resource belongs is switched to the software working mode, and the hardware equipment resource is distributed to the second resource equipment service which requests the hardware equipment resource currently, so that the problem of the hardware equipment resource conflict is solved, the running of the first multimedia service is not interrupted, and the running efficiency of the first multimedia service is improved.
Fig. 3 is a flowchart illustrating a resource control method according to another embodiment of the present application. On the basis of the foregoing embodiments, the present application describes an implementation manner in which the resource control device reallocates the hardware device resources to the first multimedia service again. As shown in fig. 3, the method of the embodiment of the present application may further include:
step S203, if the usage status of the hardware device resource is switched to the idle status, or if the first resource device service requests the hardware device resource again, switching the software device resource in the first resource device service to the hardware device resource.
In this step, the resource control apparatus may further switch the software device resource in the first resource device service to the hardware device resource again in a partial scenario, so that the hardware device resource continues to perform corresponding logic processing on the output signal of the upstream resource device service located in the first resource device service in the first hardware path.
By way of example, the following embodiments of the present application describe several possible scenarios:
in a possible scenario, if the second multimedia service is finished running, the second multimedia service does not use the hardware device resource (i.e. the hardware device resource involved in the above embodiment and conflicting with the second multimedia service, for example, the first hardware device resource in fig. 2D) any more. If it is obtained that the usage state of the hardware device resource is switched to the idle state, the resource control device switches the software device resource (e.g., the first software device resource in fig. 2B) in the first resource device service to the hardware device resource (e.g., the first hardware device resource in fig. 2B), so that the hardware device resource continues to perform corresponding logic processing on the output signal of the upstream resource device service (e.g., the third resource device service in fig. 2B) located in the first hardware path and served by the first resource device service. It can be seen that, when the conflicted hardware device resource (e.g. the first hardware device resource in fig. 2D) is in the idle state again, the first hardware device resource continues to operate for the first multimedia service by switching the first resource device service to the hardware operating mode.
In another possible scenario, if it is obtained that the first resource device service requests the hardware device resource again, the resource control apparatus switches the software device resource (for example, the first software device resource in fig. 2B) in the first resource device service to the hardware device resource (for example, the first hardware device resource in fig. 2B) again, so that the hardware device resource continues to perform corresponding logic processing on an output signal of an upstream resource device service (for example, the third resource device service in fig. 2B) located in the first hardware path and served by the first resource device service.
It should be noted that, if the second multimedia service has not been completely run when the first resource device service requests the hardware device resource again, the resource control device may further switch the hardware device resource (for example, the first hardware device resource in fig. 2D) in the second resource device service to the software device resource (for example, the first software device resource in fig. 2D), and the specific switching manner may refer to the switching manner of "switching the hardware device resource in the first resource device service to the software device resource corresponding to the hardware device resource" in step S202 in the foregoing embodiment of the present application, which is not described in detail in this embodiment of the present application.
It can be seen that, when the first resource device service requests the hardware device resource again, the first hardware device resource continues to operate for the first multimedia service by switching the first resource device service to the hardware operating mode.
Of course, the resource control apparatus may also switch the software device resource in the first resource device service to the hardware device resource again in other scenarios, which is not limited in the embodiment of the present application.
For convenience of understanding, the following embodiments of the present application describe specific implementations of "switching the software device resource in the first resource device service to the hardware device resource":
exemplarily, stopping the operation of the software device resource, and reconfiguring the hardware device resource according to the recorded state feature information corresponding to the hardware device resource and the current operation state information corresponding to the software device resource;
the state feature information corresponding to the hardware device resource is as follows: and when the hardware equipment resource in the first resource equipment service is switched into a software equipment resource corresponding to the hardware equipment resource, recording the state characteristic information.
In this embodiment, the resource control apparatus stops the operation of the software device resource (for example, the first software device resource in fig. 2B), and reconfigures the hardware device resource according to the recorded state characteristic information corresponding to the hardware device resource (for example, the first hardware device resource in fig. 2B) (that is, when the hardware device resource in the first hardware device service is switched to the software device resource corresponding to the hardware device resource, the recorded state characteristic information corresponding to the hardware device resource) and the current operation state information corresponding to the software device resource, so that the hardware device resource continues to perform corresponding logic processing on the output signal of the upstream resource device service (for example, the third resource device service in fig. 2B) located in the first hardware path and served by the first resource device service.
It should be noted that, the step of stopping the operation of the software device resource and the step of reconfiguring the hardware device resource according to the recorded status feature information corresponding to the hardware device resource and the recorded current operating status information corresponding to the software device resource are not limited in execution sequence, and may also be in other sequences (for example, the step of reconfiguring the hardware device resource and the step of stopping the operation of the software device resource are executed in sequence according to the recorded status feature information corresponding to the hardware device resource and the recorded current operating status information corresponding to the software device resource, or both of them are executed at the same time), which is not limited in the embodiment of the present application.
In another example, the resource control apparatus may further switch an output end of an upstream resource device service served by the first resource device in the first hardware path from the software device resource to the hardware device resource, and switch an input end of a downstream resource device service served by the first resource device in the first hardware path from the software device resource to the hardware device resource.
In this implementation manner, on one hand, the resource control apparatus may further switch, by the software device resource (e.g., the first software device resource in fig. 2C), the output end of the upstream resource device service (e.g., the third resource device service in fig. 2C) located in the first hardware path of the first resource device service to be connected to the hardware device resource (e.g., the first hardware device resource in fig. 2C), so that the hardware device resource continues to perform corresponding logic processing on the output signal of the upstream resource device service of the second resource device service.
On the other hand, the resource control apparatus switches the input end of the downstream resource device service (e.g. the fourth resource device service in fig. 2C) located in the first hardware path from the software device resource (e.g. the first software device resource in fig. 2C) to the hardware device resource (e.g. the first hardware device resource in fig. 2C), so that the signal obtained after the hardware device resource performs corresponding logic processing on the output signal of the upstream resource device service of the second resource device service is transmitted to the downstream resource device service of the second resource device service continuously.
Of course, the resource control apparatus may also switch the software device resource in the first resource device service to the hardware device resource in other realizable manners, which is not limited in this embodiment of the application.
In this embodiment of the present application, if the usage state of the hardware device resource is switched to the idle state, or if the first resource device service requests the hardware device resource again, the software device resource in the first resource device service is switched to the hardware device resource. It can be seen that, when the conflicted first hardware device resource is in the idle state again or when the first hardware device resource is requested by the first resource device service again, compared with the manner in which the first multimedia service needs to be restored in the related art, in this embodiment, the first hardware device resource continues to operate as the first multimedia service by directly switching the first resource device service to the hardware operating mode without restoring the flow of the first multimedia service, so that the operating efficiency of the first multimedia service is improved.
Based on the foregoing embodiment, in another embodiment of the present application, taking an example that the first multimedia service is a Digital Television (DTV) service and the second multimedia service is a Video On Demand (VOD) service, the resource control method provided in the embodiment of the present application is described in detail. Fig. 4A is a first schematic structural diagram of a first hardware path provided in another embodiment of the present application, fig. 4B is a second schematic structural diagram of the first hardware path provided in another embodiment of the present application, and fig. 4C is a second schematic structural diagram of the second hardware path provided in another embodiment of the present application. Illustratively, the method of the embodiment of the present application may specifically include:
step 1, a first hardware channel corresponding to the DTV service is established.
In this embodiment, it is assumed that a user needs to operate a DTV service, and a terminal device generally needs a tuning device service 1, a demultiplexing device service 1, a decoding device service 1, and a multimedia output device service 1 for operating the DTV service, as an example, an implementation manner for creating a first hardware path is described.
For example, when the DTV service is initialized, the resource control apparatus may receive resource request information sent by the tuner service 1, the demux service 1, the decoder service 1, and the multimedia output device service 1, respectively, where each resource request information carries an identifier of a requested hardware device resource (for example, the resource request information sent by the tuner service 1 carries an identifier of a hardware tuner, the resource request information sent by the demux service 1 carries an identifier of a hardware demux device, the resource request information sent by the decoder service 1 carries an identifier of a hardware decoder, and the resource request information sent by the multimedia output device service 1 carries an identifier of a hardware multimedia output device). Assuming that there is no conflict between hardware device resources requested by each resource device service, the resource control device allocates the requested hardware device resources to each resource device service, and connects the resource device services according to the processing sequence of the DTV service information stream to form a first hardware path as shown in fig. 4A, so as to facilitate the operation of the DTV service.
And 2, creating a second hardware path corresponding to the VOD service.
In this embodiment, it is assumed that the user needs to run the VOD service again at this time, and the terminal device usually needs the decoding device service 2 and the multimedia output device service 2 for running the VOD service, as an example, an implementable manner of creating the second hardware path is described.
For example, when the VOD service is initialized, the resource control apparatus may receive resource request information sent by the decoding device service 2 and the multimedia output device service 2, respectively, where each resource request information carries an identifier of a requested hardware device resource (for example, the resource request information sent by the decoding device service 2 carries an identifier of a hardware decoding device, and the resource request information sent by the multimedia output device service 2 carries an identifier of a hardware multimedia output device).
Further, when the resource control device obtains that the usage states of the hardware decoding device and the hardware multimedia output device are switched to the conflict state, the resource control device switches the hardware decoding device in the decoding device service 1 to the software decoding device, and switches the hardware multimedia output device in the multimedia output device service 1 to the software multimedia output device, so as to form a first hardware path as shown in fig. 4B, that is, the DTV service can continue to operate. Further, the resource control means reallocates the hardware decoding device to the decoding device service 2, reallocates the hardware multimedia output device to the multimedia output device service 2, and connects the resource device services in the order of processing of the VOD service information stream to form a second hardware path as shown in fig. 4C, so as to facilitate the operation of the VOD service.
For convenience of understanding, the following embodiments of the present application describe in detail the implementable manner of "the resource control device switches the hardware decoding device in the decoding device service 1 to the software decoding device":
in the embodiment of the present application, the resource control device stops the operation of the hardware decoding device, and records the status characteristic information of the hardware decoding device, for example, including but not limited to at least one of the following: buffer information, coding information, and audiovisual information. Further, the resource control means configures the software decoding device according to the state feature information, so that the software decoding device performs logic processing (for example, decoding processing or the like) corresponding to the hardware decoding device on the output signal of the demultiplexing device service 1. Illustratively, realizations of the logical processing of the output signals of the demultiplexing device service 1 by the software decoding device may include, but are not limited to, any of the following:
(1) no data is output;
(2) outputting a preset signal, for example, a signal corresponding to a preset display picture;
(3) determining a processing mode according to the audio and video information, for example, if the audio and video information is used for indicating audio information, or the audio and video information is used for indicating video information and the resolution is lower than a preset value, the software decoding device can directly decode an output signal of the demultiplexing device service 1; otherwise, a preset signal may be output.
Of course, the logic processing of the output signal of the demultiplexing device service 1 by the software decoding device may also include other realizable manners that do not affect the upper-layer resource device service, which is not limited in this embodiment of the application.
Optionally, the resource control apparatus may further switch the output end of the demultiplexing device service 1 from the hardware decoding device to the software decoding device, and switch the input end of the multimedia output device service 1 from the hardware decoding device to the software decoding device.
Of course, the resource control apparatus may also switch the hardware decoding device in the decoding device service 1 to a software decoding device in other realizable manners, which is not limited in this embodiment of the application.
It should be noted that, for the specific switching manner of the resource control device switching the hardware multimedia output device in the multimedia output device service 1 to the software multimedia output device, reference may be made to the above related contents of "switching the hardware decoding device in the decoding device service 1 to the software decoding device", which is not described again here.
And 3, recovering a first hardware channel corresponding to the DTV service.
In this embodiment, if the VOD service is finished or the user exits the VOD service, the resource control device may acquire that the use states of the hardware decoding device and the hardware multimedia output device are both switched to the idle state; or, assuming that the user switches to the DTV service again, the resource control device may acquire the DTV service and request the hardware decoding device and the hardware multimedia output device again. Further, the resource control apparatus switches the software decoding device in the decoding device service 1 to a hardware decoding device, and switches the software multimedia output device in the multimedia output device service 1 to a hardware multimedia output device, so as to recover the first hardware path shown in fig. 4A.
It should be noted that, when the resource control apparatus obtains that the DTV service requests the hardware decoding device and the hardware multimedia output device again, and the VOD service is not yet completed, the resource control apparatus may further switch the hardware decoding device in the decoding device service 2 to a software decoding device, and switch the hardware multimedia output device in the multimedia output device service 2 to a software multimedia output device.
For convenience of understanding, the following embodiments of the present application describe in detail the implementable manner of "the resource control device switches the software decoding device in the decoding device service 1 to the hardware decoding device":
in this embodiment, the resource control device stops the operation of the software decoding device, and reconfigures the hardware decoding device according to the recorded state feature information corresponding to the hardware decoding device and the current operation state information corresponding to the software decoding device, so that the hardware decoding device continues to perform logic processing (e.g., decoding processing, etc.) on the output signal of the demultiplexing device service 1.
Optionally, the resource control apparatus may further switch the output end of the demultiplexing device service 1 from the software decoding device to the hardware decoding device, and switch the input end of the multimedia output device service 1 from the software decoding device to the hardware decoding device.
