It should be understood that the above description is only an example for better understanding of the technical solution of the present embodiment, and is not to be taken as the only limitation of the present embodiment.
The data importing device as the data importing end may be a PC (Personal Computer ), a portable computer, a server, or the like.
The following describes the television control method in detail with reference to a flowchart of the first embodiment of the television control method shown in fig. 2.
Referring to fig. 2, an embodiment of a television control method of the present invention provides a television control method applied to a television, where the television control method includes:
Step S100, a target initialization configuration file is obtained, wherein the target initialization configuration file is used for configuring a target digital television standard corresponding to the shipping area information of the television terminal;
in this embodiment, it should be noted that, the digital television standards adopted in different regions are different, and the digital television standard adopted in the european region is "DVB"; the digital television standard adopted in the south America area is ISDB; the digital television standard adopted in North America is "ATSC". Generally, there are no two or more digital television standards in a region.
In this embodiment, it should also be noted that the target initialization configuration file is an INI file (i.e., initialization abbreviation), which is used to initialize or parameter an operating system or a specific program of the device. Therefore, the target initialization configuration file can be used for configuring a target digital television standard corresponding to the shipping area information of the television terminal. As different digital television standards differ in the manner in which the received digital signals are modulated and demodulated, multiplexed and demultiplexed, and encoded and decoded. Therefore, the INI file generated according to the information of the target digital television standard can set parameters of a system of the television end so that the television can play the digital signal of the corresponding target digital television standard.
In this embodiment, the target digital television standard corresponding to the shipping area information of the television terminal (such as a television or a set top box of the television) may be configured for the television terminal by obtaining the target initialization configuration file, so that the television realizes playing of a digital signal of the corresponding target digital television standard.
Step S200, loading the target initialization configuration file to obtain signal system parameters in the target initialization configuration file;
in this embodiment, after the television end obtains the target initialization configuration file, signal format parameters in the target initialization configuration file may be obtained by loading the target initialization configuration file. The signal system parameters include system parameters of different signal systems, such as demodulation parameters, demultiplexing parameters, audio/video decoding parameters, and the like.
The step of loading the target initialization configuration file and obtaining signal system parameters in the target initialization configuration file comprises the following steps:
step S210, based on a preset attribute system, reading the target initialization configuration file, obtaining the standard attribute of the target initialization configuration file, and loading the standard attribute into a preset attribute space;
Step S220, reading a target system attribute from the attribute space, and acquiring a signal system parameter corresponding to the target system attribute based on the target system attribute.
In this embodiment, it should be noted that the preset attribute system is a system for accessing a system attribute by a software component of the whole system of the television end, that is, a Property mechanism. Therefore, the UI (user interface) layer and the middleware layer of the television end are signal system parameters for accessing the configured digital television standard. It can be understood that if the operating system of the television terminal is an android system, the Property mechanism is natively supported, that is, the preset Property system exists in the operating system of the television terminal. If the operating system of the television terminal is not an android system, a software tool package corresponding to the Property mechanism can be obtained and loaded, so that the preset Property system is transplanted in the operating system of the television terminal.
In this embodiment, based on a preset attribute system, the target initialization configuration file is read, the format attribute of the target initialization configuration file is obtained, and the format attribute is loaded into a preset attribute space. The preset attribute space is a shared storage space of the whole system of the television end, so that software components in the whole system can access standard attributes in the preset attribute space. When the television receives the standard triggering instruction, the target standard attribute can be read from the attribute space, and the signal standard parameter corresponding to the target standard attribute is acquired based on the target standard attribute. Therefore, the system attribute in the target initialization configuration file is loaded into the attribute space through the preset attribute system, so that the television end can read the target system attribute from the attribute space, and based on the target system attribute, the signal system parameter corresponding to the target system attribute is acquired and used for data processing of the received digital signal.
The step of reading the target system attribute from the attribute space and acquiring the signal system parameter corresponding to the target system attribute based on the target system attribute comprises the following steps:
step S221, responding to a system triggering instruction, and acquiring signal system parameters corresponding to the target system attributes based on a target system interface corresponding to the system triggering instruction, wherein the target system interface is an interface provided by a middleware of the television terminal based on the target system attributes.
In this embodiment, it should be noted that, since the user does not necessarily use the digital television related function of the television, the user may watch the local video through a usb disk, a storage hard disk, or the like, for example. Therefore, when the user needs to use the related functions of the digital television, a system triggering instruction is issued to the television terminal.
In this embodiment, it should be further noted that the target standard interface is an interface provided by the middleware of the tv end based on the target standard attribute. The target standard interface is an interface which is realized and provided by the middleware of the television terminal after the target standard attribute is read from the attribute space. The target standard interface can be an interface which is realized and provided by the middleware of the television terminal in advance, or can be an interface which is realized and provided by the middleware of the television terminal in real time.
The embodiment determines that the user needs to use the related functions of the digital television by responding to the system triggering instruction. And further, acquiring signal system parameters corresponding to the target system attributes based on the target system interface corresponding to the system triggering instruction. When a user needs to use the related function of the digital television, the signal system parameters corresponding to the target system attributes are acquired based on the target system interface corresponding to the system triggering instruction so as to realize the related function of the digital television required by the user.
After the step of reading the target initialization configuration file, obtaining the standard attribute of the target initialization configuration file, and loading the standard attribute into a preset attribute space, the television control method further comprises:
step A10, reading a target system attribute from the attribute space, and determining a corresponding interactive display parameter according to the target system attribute;
and step A20, displaying corresponding interactive contents according to the interactive display parameters.
In this embodiment, it should be noted that different system attributes have corresponding interactive display contents. For example, source has different naming modes according to the signal transmission mode and the digital television standard as shown in table 1 below. Wherein DVB, ISDB, ATSC is digital television standard, and ground, cable and satellite are signal propagation modes. And corresponding modes are arranged between each digital television standard and each signal transmission mode. Therefore, the source corresponding to the target system attribute in the terrestrial transmission mode of the digital television standard DVB is named as DVB-T/T2, the source corresponding to the target system attribute in the cable transmission mode of the digital television standard DVB is named as DVB-C, the source corresponding to the target system attribute in the satellite transmission mode of the digital television standard DVB is named as DVB-S/S2, and so on. The digital television standards ISDB and ATSC are systems in which no satellite is a signal propagation mode at present, so that no corresponding source naming exists.
TABLE 1 correspondence table of target System attributes and Source naming
In addition, the menu presentation functions of different digital television standards are different, such as digital television standard DVB having subtitle and teletext options, and digital television standards ISDB and ATSC having closed captioning (closed caption) and digital television standard ATSC having V-chip functions.
Therefore, the embodiment reads the target format attribute from the attribute space and determines the corresponding interactive display parameter according to the target format attribute. And then displaying the corresponding interactive content according to the interactive display parameters. Therefore, the television end displays interactive display contents corresponding to the standard attributes of different digital television standards.
And step S300, carrying out corresponding data processing operation on the received digital signals according to the signal system parameters to obtain audio and video signals, and controlling a television end to play the audio and video signals.
In this embodiment, it should be noted that, because the audio and video signals to be transmitted by different digital television standards are generally transmitted to the television end through the transmission modes of the ground, the cable or the satellite after the audio and video coding, multiplexing, modulation and other data processing operations, the audio and video signals can be restored after the corresponding data processing operations are performed on the received digital signals by adopting the corresponding signal system parameters.
Therefore, according to the signal system parameters, the embodiment carries out corresponding data processing operation on the received digital signals, so that the received digital signals are restored into audio and video signals. And further, the television terminal can be controlled to play the audio and video signals, so that the playing of the digital signals of the target digital television standard corresponding to the shipping area information of the television terminal is realized.
Referring to fig. 3, fig. 3 is a flowchart illustrating a step S300 in a first embodiment of a television control method according to the present invention.
In this embodiment, the signal format parameters at least include demodulation parameters, demultiplexing parameters, and audio/video decoding parameters, and the step of performing corresponding data processing operations on the received digital signal according to the signal format parameters to obtain an audio/video signal includes:
step S310, demodulating the received digital signal based on the demodulation parameters to obtain a demodulated digital signal;
step S320, performing a demultiplexing operation on the demodulated digital signal based on the demultiplexing parameter, to obtain a demultiplexed digital signal;
step S330, based on the audio/video decoding parameters, performs decoding operation on the demultiplexed digital signal to obtain an audio/video signal.
In this embodiment, it should be noted that the signal format parameters at least include demodulation parameters, demultiplexing parameters, and audio/video decoding parameters.
In this embodiment, after receiving the digital signal, the demodulation digital signal is obtained by performing a demodulation operation on the received digital signal based on the demodulation parameter. And then, based on the demultiplexing parameters, performing demultiplexing operation on the demodulated digital signals to obtain demultiplexed digital signals. And then decoding the demultiplexed digital signals based on the audio/video decoding parameters to obtain audio/video signals. The received digital signal may be restored to an audio-visual signal. And further, the audio and video signals can be played by controlling the television terminal, so that the playing of the digital signals of the target digital television standard corresponding to the shipping area information of the television terminal can be realized.
In a first embodiment of the present invention, the television control method is applied to a television terminal, and the target initialization configuration file is used for configuring a target digital television standard corresponding to shipping area information of the television terminal by acquiring the target initialization configuration file; loading the target initialization configuration file to obtain signal system parameters in the target initialization configuration file; and carrying out corresponding data processing operation on the received digital signals according to the signal system parameters to obtain audio and video signals, and controlling a television end to play the audio and video signals. Therefore, according to different shipping areas of the television terminal, the target initialization configuration file can be correspondingly loaded into the television terminal, so that corresponding digital television standard software does not need to be independently developed for different areas, and the software maintenance cost is effectively reduced.
The following describes the television control method in detail with reference to a flowchart of a second embodiment of the television control method shown in fig. 3.
Referring to fig. 3, in another embodiment of the television control method of the present invention, the method is applied to a data importing end, and is characterized in that the television control method includes:
step B10, acquiring shipping area information of a television end, and determining corresponding target digital television standard information according to the shipping area information;
and step B20, according to the target digital television standard information, acquiring a target standard file corresponding to the target digital television standard information, packaging the target standard file into an initialization configuration file, and transmitting the initialization configuration file to a television terminal.
In this embodiment, the data importing end may be a PC (Personal Computer ), a portable computer, a server, or the like.
In this embodiment, it should be further noted that, in the television sets in different shipment areas, corresponding digital television standards need to be configured. See table 2 below for three digital television standards, DVB, ISDB and ATSC, respectively, depending on the shipping area. In addition, transmission modes according to digital television signals include terrestrial (terrestrial), cable (cable) and satellite (satellite).
