Detailed Description
In order to make the present invention better understood by those skilled in the art, the following description will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Definition of unique in Unicable specification: satellite signal distribution over a single coaxial cable in single dwelling installations, i.e. the satellite signals are distributed to the rooms in a single building via a single coaxial cable. Unicable devices are divided into two generations, where the standard for Unicable I (first generation device) is EN_50494, published 2007, and the standard for Unicable II (second generation device) is EN_50607, published 2015. The first generation unique device and the second generation unique device are different in that: 1. the available user ports are different, and the available user ports of the first-generation unique device are at most 8, and the available user ports of the second-generation unique device are at most 32. 2. The number of accessible satellites is different, and the first generation of unique devices can only have 8 BANK (branches), namely 2 satellites, and the second generation of unique devices can only have 256 BANK, namely 64 satellites. 3. The command format and the command function are also different, and the second-generation Unicable device has a unidirectional transmission function and is additionally provided with a bidirectional communication function; simultaneously, a command of a new function is added; while a Unicable device of the generation has only a unidirectional transmission function.
Because the current television needs to manually select whether the Unicable device in use is a first-generation Unicable device or a second-generation Unicable device in the Unicable setting item, and most users basically do not know whether the Unicable device in use is the first-generation device or the second-generation device, the situation of setting errors is easy to occur, and the use of the users is influenced. In order to solve the problem, the invention can automatically identify whether the Unicable device in use is a generation Unicable device or a second generation Unicable device according to the inherent characteristics of the generation Unicable device and the second generation Unicable device. Specifically, since the first generation Unicable device and the second generation Unicable device are different devices, and for the same diseqc command, one of the first generation Unicable device and the second generation Unicable device has feedback, and the other is not fed back, the invention realizes the effect of automatic identification of the Unicable device by sending two different diseqc commands (namely a first diseqc command and a second diseqc command) to the Unicable device, and analyzing the feedback made by the Unicable device after receiving the diseqc command, thereby judging whether the Unicable device in use is the first generation Unicable device or the second generation Unicable device. The diseq (digital satellite equipment control, digital satellite device control) command is controlled by a digital satellite television receiver, and sends an instruction set (control instruction) to a corresponding device, such as a switch, a switcher, an antenna driving device, an LNB, and the like. Preferably, in the embodiment of the present invention, since the first generation Unicable device and the second generation Unicable device have inherent features, in order to more accurately identify whether the Unicable device is the first generation Unicable device or the second generation Unicable device, the embodiment of the present invention may send different diseqc commands to the Unicable device, where the sent diseqc commands are targeted and respectively correspond to the first generation Unicable device and the second generation Unicable device. When the first generation Unicable device or the second generation Unicable device receives the corresponding diseqc command, corresponding feedback is made. After sending two different diseqc commands (namely a first diseqc command and a second diseqc command) to a Unicable device, if a central carrier sent by the Unicable device in response to the first diseqc command is searched, determining that the Unicable device is a generation Unicable device; and if the third request command replied by the Unicable device in response to the second request command is received, the Unicable device is judged to be the second generation Unicable device, so that whether the Unicable device is the first generation Unicable device or the second generation Unicable device is accurately identified, the identification accuracy of the Unicable device is improved, the user does not need to manually select, and the convenience is provided for the user.
Exemplary method
As shown in FIG. 1, the embodiment of the invention provides a Unicable equipment identification method. In this embodiment, the method shown comprises the steps of:
step S100, when the source is a satellite television source and is in a Unicable mode, a first digital satellite device control (dis eq) command and a second digital satellite device control (dis) command are sent to the Unicable device in response to a Unicable device selection instruction.
In this embodiment, since the Unicable is located as follows: satellite signal distribution over a single coaxial cable in single dwelling installations, that is, the distribution of satellite signals to each room device by a single coaxial cable in a single building is used to distribute satellite signals to each room, so that the television or set-top box device in each room can receive satellite signals, and thus can watch television programs. Therefore, in this embodiment, after the television or the set-top box device is turned on, the acquisition of the source data is started, and it is determined whether the source data is a satellite television source. The information source data is the information source data, and whether the television or the set top box equipment is connected with the Unicable equipment (namely whether the television or the set top box equipment is judged to be using the Unicable equipment) can be judged by judging whether the information source data is a satellite television information source, which is a premise of entering a Unicable equipment identification process. Further, after obtaining the source data and judging that the source data is a satellite television source, further obtaining whether the mode of the satellite television source is in a Unicable mode, wherein the Unicable mode is used for selecting and setting Unicable equipment (namely, setting whether the Unicable equipment in use is a generation Unicable equipment or a second generation Unicable equipment). That is, when it is determined that the mode of the satellite television source is in the Unicable mode, it is indicated that the Unicable device being used needs to be selected and set in the Unicable mode at this time (i.e., whether the Unicable device being used is a first-generation Unicable device or a second-generation Unicable device is set), and then the identification of the Unicable device is started.
Further, since the feedback made by the first generation Unicable device and the second generation Unicable device for different diseqc commands is different, the embodiment accurately determines whether the Unicable device is the first generation Unicable device or the second generation Unicable device by sending different diseqc commands to the Unicable device and analyzing the feedback made by the Unicable device according to the corresponding diseqc commands. Specifically, when the source of the television or the set-top box device is a satellite television source and the satellite television source is in a Unicable mode, the Unicable device (the Unicable device is a device in use by the television or the set-top box device) sends a first diseqc command and a second diseqc command, so that feedback made by the Unicable device after receiving the first diseqc command and the second diseqc command is analyzed in a subsequent step, and the Unicable device is identified.
When the television or the set-top box is started, the acquisition of the information source data is automatically started, and whether the acquired information source data is a satellite television information source or not is judged after the information source data is acquired. If the acquired information source data is a satellite television information source, the fact that the television or the set top box device is using the Unicable device at the moment is indicated, and whether the Unicable device in use is a first-generation Unicable device or a second-generation Unicable device needs to be judged. If the acquired information source data is not the satellite television information source, the fact that the television or the set top box equipment is not using the Unicable equipment at the moment is indicated, and identification of the Unicable equipment is not needed. Further, when the acquired information source data is a satellite television information source, whether the satellite television information source is in a Unicable mode is further judged, when the satellite television information source is in the Unicable mode, whether the Unicable equipment in use is a first-generation Unicable equipment or a second-generation Unicable equipment needs to be selected from Unicable setting items in the Unicable mode at the moment, so that an identification flow of the Unicable equipment is carried out when the Unicable equipment is started, and a first diseqc command and a second diseqc command are sent to the Unicable equipment; when the satellite television source is not in the Unicable mode, the Unicable device does not need to be identified.
Preferably, in this embodiment, after the television or the set-top box device is turned on, searching for a Unicable parameter is automatically started, where the Unicable parameter is used to embody that the Unicable device is a first-generation Unicable device or a second-generation Unicable device. When the Unicable parameters are searched, it is indicated that the television or the set-top box device has been configured with the Unicable parameters (that is, whether the used Unicable device is a first-generation Unicable device or a second-generation Unicable device has been identified before), so that the Unicable parameters are directly called without identifying the Unicable device used by the television or the set-top box device, and efficiency is improved. And when the Unicable parameters are not searched, entering the identification program of the Unicable device, namely performing the operation of the step S100.
Further, step S200 is to determine that the Unicable device is a first generation Unicable device if the central carrier sent by the Unicable device in response to the first request command is searched.
Since the first-generation Unicable device and the second-generation Unicable device have inherent features, for the first-generation Unicable device, the first-generation Unicable device cannot answer the diseqc command, but transmits the diseqc command: e0005B00, can make its user port with normal function (i.e. can normally generate the center carrier) generate the center carrier, as shown in FIG. 3, the center carriers sent by all user ports (UB_1, UB_2, UB_3, UB_4) with normal function of a Unicable device are shown. Based on this, the present embodiment can send a diseqc command to the television or the set-top box device: E0005B0000, and judges whether the Unicable device is a generation device by searching for a center carrier. Thus, the first disk command in this embodiment is E0005b00, which is used to control all available user ports of the Unicable device to generate a center carrier. After the television or the set top box device sends a first request command to the Unicable device, the central carrier wave is searched, and the Unicable device capable of generating the central carrier wave is the first-generation Unicable device, so that whether the Unicable device is the first-generation Unicable device can be identified by whether the central carrier wave is searched. That is, the first disk command in the present embodiment: e0005B00 is used for identifying whether the Unicable device is a generation Unicable device.
As shown in fig. 2, the identification of the first-generation Unicable device in this embodiment specifically includes the following steps:
step S201, after the first disk command is sent to the Unicable device, a carrier data searching function is started;
step S202, when carrier data is searched, the carrier data is identified and locked, and whether the carrier data is a central carrier sent by the Unicable equipment when receiving the first disk command is judged;
step 203, if the carrier data is a central carrier sent by the Unicable device when receiving the first request command, determining that the Unicable device is a generation Unicable device;
step S204, the central carrier wave is saved, and the Unicable equipment identification program is exited.
In a specific implementation, after a first disk command is sent to the Unicable device, the television or the set-top box device starts a carrier data searching function, and a tuner and a mediation chip (device) of the television or the set-top box device search carrier data. The searched carrier data is not necessarily derived from the Unicable device, so that it is necessary to identify and lock the searched carrier data, and determine whether the carrier data is a central carrier sent by the Unicable device by the user port thereof under the control of the first disk command. When the carrier data is identified as originating from a Unicable device and the carrier data is locked to a central carrier generated by all available user ports of the Unicable device, the Unicable device can be identified as a generation Unicable device. When the television or the set top box device is identified to be used by the Unicable device, the searched central carrier wave is stored, and then the Unicable device identification program is exited. Because the Unicable device is identified as the first-generation Unicable device at the moment, the television or the set top box device displays a setting item interface corresponding to the first-generation Unicable device for the user to set.
Further, step S300 is to determine that the Unicable device is a second generation Unicable device if a third digital satellite device control (diseqc) command replied by the Unicable device in response to the second diseqc command is received.
In this embodiment, when the television or the set-top box device does not search for the center carrier, it is indicated that the first disc command is received by the Unicable device, and the Unicable device does not control all available user ports of the Unicable device to generate the center carrier, which may indicate that the Unicable device is not a first-generation Unicable device. When it is recognized that the Unicable device is not a first-generation Unicable device, it is necessary to further recognize whether the Unicable device is a second-generation Unicable device. And because the first generation Unicable device and the second generation Unicable device have inherent characteristics, the second generation Unicable device cannot generate a center carrier wave due to the first disk command. But the Unicable device will answer the diseqc command. If a Unicable device receives a second diseqc command, such as 7A (second diseqc command identifier), responds to the second diseqc command, and replies a third diseqc command, where the third diseqc command includes a third diseqc command identifier (74), first data (data 1), second data (data 2), third data (data 3) and fourth data (data 4), and the information in the replied third diseqc command indicates how many user ports of the Unicable device are functioning normally. When the third disk command is received: 74 After data1 data2 data3 data4 is analyzed, if specific data can be analyzed, the fact that the unique device is a second-generation unique device is indicated. Therefore, the embodiment further identifies whether the Unicable device is a second generation Unicable device by sending a second diseqc command to the Unicable device, where the second diseqc command is 7A. After the Unicable device sends the second diseqc command, if the Unicable device can receive a third diseqc command (74 data1 data2 data3 data4) replied to the second diseqc command, and parse the third diseqc command, thereby identifying whether the Unicable device is a second-generation Unicable device.
It should be noted that the second diseqc command is different from the first diseqc command, and the first diseqc command is used to identify whether the Unicable device is a generation Unicable device; the second diseqc command is used for identifying whether the Unicable device is a second generation Unicable device, so that the first diseqc command and the second diseqc command are different in diseqc command, and have pertinence, and the Unicable device can be identified more accurately for the first generation Unicable device and the second generation Unicable device respectively.
Specifically, as shown in fig. 4, the identification of the second generation Unicable device includes the steps of:
step S401, when receiving command data sent by the Unicable device after sending the second dis eq command to the Unicable device, identifying and analyzing the command data, and determining whether the command data is a third dis command replied by the Unicable device according to the second dis command;
step S402, if the command data is a third diseqc command returned by the Unicable device according to the second diseqc command, analyzing the third diseqc command, and judging whether the device parameter information can be analyzed from the third diseqc command;
step S403, when the device parameter information is analyzed from the third request command, determining that the Unicable device is a second-generation Unicable device;
and step S404, saving the device parameter information, and exiting the Unicable device identification program.
In this embodiment, after the Unicable device receives the second dis eq command, the television or the set top box device starts to identify and parse the received command data, and because there are many command data received by the television or the set top box device in the running process, the purpose of identifying and parsing the command data in this embodiment is to determine whether the received command data is the third dis command replied by the Unicable device in response to the second dis command, that is, whether the received command data is 74 data1 data2 data3 data4. When the parsed command data is a third diseqc command, the third diseqc command is parsed, and whether the device parameter information can be parsed from the third diseqc command, that is, whether the meanings of data1, data2, data3 and data4 in the third diseqc command can be parsed, whether the number of user ports with normal functions and the information of the user ports with normal functions can be parsed from the third diseqc command is judged, if the device parameter information can be parsed, the Unicable device used by the television or the set top box device is the second-generation Unicable device. When the Unicable device is identified as the second generation Unicable device, the device parameter information is stored, and then the Unicable device identification program is exited. Because the Unicable device is identified as the second-generation Unicable device at the moment, the television or the set top box device displays a setting item interface corresponding to the second-generation Unicable device for the user to set.
Preferably, if the television or the set-top box device does not receive the third request command replied by the Unicable device in response to the second request command, it is determined that the Unicable device is not a second-generation Unicable device. Whereas the previous first diseqc command has identified that the Unicable device is not a generation Unicable device, it can be derived that the Unicable device is neither a generation Unicable device nor a second generation Unicable device.
