Referring to fig. 2, in an embodiment, the source switching method of the television includes:
step S10, when receiving an information source switching instruction, acquiring a target information source according to the information source switching instruction;
in the present embodiment, the tv set has a plurality of sources, which may be HDMI, YPBPR, AV, VGA, etc., but is not limited to the above source types. The television switches the current playing information source according to different application requirements, for example, the television is currently in a digital television information source playing mode, and a user requests a network video through a certain network video application, so that the smart television needs to switch to a multimedia information source playing mode.
Specifically, when a user needs to switch the information source, the user may send an information source switching instruction to the television through the remote controller, or send an information source switching instruction to the television by pressing an information source switching button of the television, or may preset an information source switching rule, for example, automatically switch to the information source corresponding to the application after the preset application is started, and may be flexibly set in the actual application.
It should be noted that, after receiving the signal source switching instruction, the television acquires the target signal source. The television needs to switch from the current source input port to the target source input port to receive the video signal transmitted by the target external source device through the target source input port.
It should be noted that, the obtaining of the target source according to the source switching instruction is not limited to be performed in this step, and may be performed between receiving the source switching instruction and extracting the target source data.
Step S20, erasing the information source data of the current connection information source of the register;
it should be noted that the register is a small storage area for storing data inside the CPU, and is used for temporarily storing data participating in the operation and operation results. The register is generally a D trigger derived from a basic RS trigger structure, and the read-write speed of the register is basically matched with the running speed of a CPU. Different registers have different roles, such as: general purpose registers (GR) for holding operands, addresses of operands, or intermediate results; the Instruction Register (IR) is used to store the currently executing instruction so as to control the completion of the entire function of an instruction during the execution of the instruction. The register is used, so that the storage space can be saved, and the execution speed of the instruction can be improved.
Specifically, when the CPU performs calculation, data to be used is read from the hard disk to the memory in advance, and then the data to be used is read from the memory to the register. The most ideal situation is that all data of the CPU can be read from the register, so that the reading and writing speed is high, but if the register does not have the data to be used, the data can be read from the memory or even the hard disk.
And when receiving a source switching instruction, erasing source data of the current connection source from the register so as to switch the target source. It should be noted that the source data currently connected to the source by the register includes control data of the channel, hard disk partition management tool data, window data, graphic equalizer data, and other data related to source data transmission. Specifically, the creation of the source data can be performed in the following cases: for example, in the using process of a television, when information source data is switched, when the information source data does not exist in a memory, the information source data needs to be created; or when the television is started, the source data is created no matter whether the user uses the source data or not.
Step S30, extracting the source data of the target source from the memory, and storing the source data of the target source in the register for source switching.
In this embodiment, source data of a target source is extracted from a memory, and the extracted source data is stored in a register. It should be noted that the source data includes control data of the channel, hard disk partition management tool data, window data, graphic equalizer data, and the like, which relate to the source data transmission. When creating the information source data, firstly, the information source data of the information source connected with the television is obtained, and then the information source data is stored in the memory according to a certain structure and sequence, wherein the specific structure and sequence can be flexibly set in practical application, and the invention is not limited. When the source data of the target source is extracted from the memory, the source data of the target source can be stored in the register according to the structure and the sequence.
The created source data can be stored in a memory, a memory management function can be called to apply for a memory space to store created New source information, the memory management function can be HeapAlloc, GlobalAlloc, L oclalAlloc, VirtualAlloc, Malloc, New and the like, wherein the HeapA L loc is used for allocating memory on a designated heap, and the allocated memory is not movable, the GlobalAlloc is used for allocating memory from a global heap for a program to use, L oclalAlloc is used for allocating memory from a local heap for the program to use, the VirtualAlloc functions are virtual address space of a calling process and reserve or submit a part of page, Malloc/Free is a standard library function of C + +/C language and can be used for applying for a dynamic memory and releasing the memory, and New/Delete is an operator of C and can be used for applying for a dynamic memory and releasing the memory.
It should be noted that, the conventional source switching method is a process of reconstructing a signal from input to output, and includes switching channels, identifying a signal, setting a hard disk partition management tool, setting a window, setting a graphic equalizer, and the like. The invention stores the created information source data into the memory by using the applied memory space, and directly extracts the information source data from the memory when the information source is switched, thereby saving the time of information source switching.
In this embodiment, first, when an information source switching instruction is received, a target information source is obtained according to the information source switching instruction, then, information source data of the register currently connected with the information source is erased, and finally, the information source data of the target information source is extracted from the memory and stored in the register, so as to perform information source switching. Therefore, the information source data of the target information source is directly stored in the register, namely, the switching of the information source is realized, the operations such as signal identification, data setting and the like do not need to be carried out again, and the rapid switching of the information source is realized.
In an embodiment, as shown in fig. 3, based on the embodiment shown in fig. 2, the method for switching the source of the television further includes:
step S40, when the signal source switching instruction is received, extracting the signal source data of the current connection signal source of the register;
and step S50, storing the source data in the memory.
Specifically, when the source switching instruction is received, the source data of the register currently connected to the source may be erased, or the source data of the register currently connected to the source may be extracted and stored in the memory. Therefore, when the information source is switched next time, the information source data can be directly extracted from the memory without reestablishing the information source data when an information source switching instruction is received, and instant switching can be achieved.
In this embodiment, first, when the source switching instruction is received, the source data of the currently connected source of the register is extracted, and then the source data is stored in the memory. Therefore, when the information source is switched, the information source data of the target information source can be directly extracted from the memory and stored in the register without operations such as signal identification, data setting and the like, and the information source is quickly switched.
In an embodiment, as shown in fig. 4, based on the embodiment shown in fig. 3, the method for switching the source of the television further includes:
step S60, when the information source switching instruction is received, judging whether the information source data of the current connection information source is stored in the memory;
specifically, when switching the source data, it is detected whether the source data of the currently connected source is stored in the memory, and if the source data of the currently connected source exists in the memory, the source data of the register can be erased.
And step S70, when the source data of the current connection source is not stored, executing the step S40, namely extracting the source data of the current connection source of the register.
Specifically, when switching the source data, detecting whether the source data of the current connection source is stored in the memory, if not, extracting the source data of the current connection source from the register, and then storing the extracted source data into the memory so as to directly extract and use the source data when switching the source next time.
In this embodiment, first, when the source switching instruction is received, it is determined whether source data of the currently connected source is already stored in the memory, and then, when the source data of the currently connected source is not stored, the step of extracting the source data of the currently connected source of the register is performed. Therefore, the information source data are prevented from being repeatedly stored in the memory, and the information source data of the target information source can be directly extracted from the memory and stored in the register when the information source is switched without operations such as signal identification, data setting and the like, so that the information source is quickly switched.
In an embodiment, as shown in fig. 5, based on the embodiment shown in fig. 2, the method for switching between television sources further includes:
step S80, when the television is turned on, obtaining the source data of all the sources connected to the television, and storing the source data in the memory.
Specifically, the information source data can be created when the television is turned on, that is, whether a user uses the information source data or not, the information source data of all the information sources connected to the television is acquired, and the information source data is stored in the memory and directly extracted and used when the information sources are switched.
In this embodiment, when the television is turned on, the source data of all the sources connected to the television is acquired, and the source data is stored in the memory. Therefore, the information source data of all information sources connected with the television are stored in the memory when the television is started, and the information source data of the target information source is directly stored in the register when the information source is switched without operations such as signal identification, data setting and the like, so that the information source is quickly switched.
In an embodiment, as shown in fig. 6, based on the embodiment shown in fig. 2, the method for switching between television sources further includes:
step S90, when the television is started, judging whether the flash memory of the television has information source data;
it should be noted that the source data may be stored in the memory or the flash memory. When the television is shut down or powered off, the data in the memory can be lost, and the data in the flash memory is not influenced by the shutdown or the power failure of the television. When the television is started, whether the source data exists in the flash memory is detected.
Step S100, when no information source data exists in a flash memory of the television, acquiring information source data of all information sources connected with the television, storing the information source data into the memory, and storing the information source data into the flash memory;
in this embodiment, when there is no source data in the flash memory of the television, the source data of all the sources connected to the television is acquired and stored in the flash memory as well as the memory. Therefore, when the television is turned off or turned on again after power failure, the information source data in the memory is lost, but the information source data can be obtained from the flash memory, and the information source data is prevented from being rebuilt again.
Step S110, when there is source data in the flash memory of the television, storing the source data in the flash memory into the memory.
Specifically, when the source data exists in the flash memory of the television, the source data is directly extracted from the flash memory and stored in the memory, so that the step of recreating the source information is omitted.
In this embodiment, first, when the television is turned on, it is determined whether there is source data in the flash memory of the television, then, when there is no source data in the flash memory of the television, source data of all source connected to the television is acquired, the source data is stored in the memory, and the source data is stored in the flash memory, and finally, when there is source data in the flash memory of the television, the source data in the flash memory is stored in the memory. Therefore, the source data of the target source is stored in the memory and the flash memory, and when the television is turned off or is turned on again after power failure, the source data in the flash memory is stored in the memory, so that the source data is prevented from being created again.
In an embodiment, as shown in fig. 7, the method for switching between television sources further includes:
step S120, when an information source switching instruction is received, controlling the television to enter a black screen state;
and step S130, after the television finishes information source switching, controlling the television to exit a black screen state.
It should be noted that after erasing or extracting the source data of the currently connected source of the register and before switching into the target source, the picture of the television may have an instant screen splash phenomenon because the user changes the input signal, for example, the resolution of the HDMI source changes from 1080I to 1080P. In order to solve the problem, when an information source switching instruction is received, the television can be controlled to enter a black screen state, and after the information source switching is completed, the checking state is stable, and the black screen state is exited.
In this embodiment, first, when an information source switching instruction is received, the television is controlled to enter a black screen state, and then, after the information source switching is completed, the television is controlled to exit the black screen state. Therefore, the phenomenon of instant screen splash and the like of the television in the information source switching process is avoided.
