Abstract
The present invention relates to a digital television device and the method with compatible multiple channels. The device divides the digital television receiving module and the television main machine, an interface module is utilized to connect the digital television receiving module and the television main machine, and the standard transmission stream and communication protocol output by the digital television module are transmitted to the television main machine through the interface module. When the channel is changed, the television main machine can recognize the channel transmission method of the digital television according to the communication protocol, thereby, the user only needs to replace the receiving module instead of changing the whole digital device when the channel is changed, unnecessary cost is decreased, and the replacement is convenient.
Description
Technical field
The present invention relates to a kind of implementation method of digital television apparatus, particularly a kind of implementation method that can compatible multi channel digital television apparatus.
Background technology
At present, China is in Digital Television and transforms period, because market is on TV substantially based on simulated television now, the master chip of existing simulated television is not supported the input of digital television signal.The user takes simulated television to add the mode of set-top box when watching Digital Television substantially, and promptly by the set-top box receiving digital television signal, programme signal is transformed on the simulated television by set-top box.Certainly, along with the development of Digital Television industry, simulated television will be substituted by digital television gradually.Because there are diversity in digital-TV channel transmission means and transmission standard at present, as European DVB-T standard, the DVB-S standard of satellite and the DMB-T of domestic Tsing-Hua University, the standards such as ADTB-T of Shanghai Communications University, receive the different tuner of signal demand of different channels, the transmission means or the standard of only corresponding certain channel of present set-top box or digital television, therefore the user certainly will need to change television set or buy other devices when changing channel; Manufacturer also needs to produce different digital television apparatus at different channels, as set-top box or digital television, has increased the cost of user and manufacturer on the one hand, even is not beneficial to the development of Digital Television industry on the other hand.
Summary of the invention
The object of the present invention is to provide a kind of implementation method that can compatible multi channel digital television apparatus, utilize implementation method of the present invention, can realize the conversion between a plurality of different channels, make the user can change channel simply and easily.
For achieving the above object, the invention provides a kind of implementation method that can compatible multi channel Digital Television, described digital television apparatus comprises digital TV receiver module and TV main frame, and described digital TV receiver module separates setting with the TV main frame; Described implementation method may further comprise the steps:
1) in the memory of TV main frame, writes the information of various digital TV receiver modules;
2) connecting digital TV receiver module and TV main frame with interface module, is the digital TV receiver module power supply by the power interface of interface module;
3) digital TV receiver module is exported host-host protocol by USB interface, passes to the USB interface of TV main frame by interface module, and the TV main frame is read the information of digital TV receiver module by USB interface, and compares with module information in the memory;
4) the TV main frame finds the module information consistent with the information that receives in memory, the determination module type, and return to digital TV receiver module;
5) digital TV receiver module is set up clock with the TV main frame and is communicated by letter, transmit clock signal and synchronizing signal, for the data-signal transmission ready;
6) digital TV receiver module is handled the channel signal that receives, outputting standard TS stream;
7) standard TS stream passes to the TV main frame by the data-signal of interface module, and the TV main frame receives TS stream, converts the video and audio signal of respective program to, shows and plays.
Further, the module type this method step 4) can be DMB-T, DVB-T, DVB-C, DVB-S or ADTB-T.
The present invention makes it compared with prior art to have the following advantages owing to adopted above-mentioned technical scheme:
1) user does not need to buy different digital television apparatus or multiple external device when watching the program of different channels, only needs to change receiver module, has reduced the cost of purchase of equipment;
2) producer does not consider the digital television signal transmission means when producing whole set of television, as long as interface is fixed up, the module of receiving digital television is produced separately, can save resource and production cost;
3) the receiver module replacing is simple and convenient, does not need external power supply.
Description of drawings
Implementation method that can compatible multi channel digital television apparatus of the present invention is provided by following embodiment and accompanying drawing.
Fig. 1 for the embodiment of implementation method of the present invention use can compatible multi channel digital television apparatus structured flowchart.
Embodiment
Below with reference to accompanying drawing implementation method that can compatible multi channel digital television apparatus of the present invention is described in further detail.
Digital television apparatus as shown in Figure 1, this device comprise a digital TV receiver module 1, and the core of this receiver module is that digital television signal receives tuner 11.Digital television apparatus also comprises TV main frame 3 and the interface module 2 that connects digital TV receiver module 1 and TV main frame 3.Interface module 2 is connected by serial line interface (SPI interface) with digital TV receiver module 1 and TV main frame 3, it connects signal: data-signal (SPI_0 is to SPI_7), clock signal (SPI_CLK), data useful signal (SPI_VALID) and synchronizing signal (SPI_SYNC).Data signals transmitted is the standard transmission stream (TS stream) from digital TV receiver module 1 output.The communication protocol of digital TV receiver module 1 and TV main frame 3 is transferred to interface module 2 by the USB interface of digital TV receiver module 1, is passed to the USB interface of TV main frame 3 again by interface module 2.After TV main frame 3 receives agreement, with tuner module type in the memory (not shown) relatively, judge the module type of digital television signal receiving terminal tuner 11, i.e. transmission channel mode, and return to digital TV receiver module 1; Digital TV receiver module 1 is set up clock with TV main frame 3 and is communicated by letter, and transmit clock signal and synchronizing signal are for the data-signal transmission is got ready; Digital TV receiver module 1 is handled the channel signal that receives, outputting standard TS stream; Standard TS stream passes to TV main frame 3 by the data-signal of interface module 2, and TV main frame 3 receives TS stream, converts the video and audio signal of respective program to, shows and plays.
