Fig. 1 is the high-level schematic functional block diagram of the utility model remote controller,
Fig. 2 is the related digital television system module diagram of the utility model.
[embodiment]
See also Fig. 1, the of the present utility model reception shows, and the remote controller of transmitting from digital TV set-top box or digital TV integrated machine second programs mainly comprises functional module as described below:
(1) display screen of a certain size and resolution and driver module thereof constitute display module, and display screen can be the screen that existing arbitrary Display Technique realizes, for example typical application can be the TFT liquid crystal display screen of 2.5 inches 640 * 480 64K look;
(2) processor of certain data processing capability or controller are as 32 flush bonding processors more than the 80MHZ;
(3) demodulation multiplexer and MEPG2 audio/video decoder constitute decoder module;
(4) wireless telecommunications and driver module for example use 802.11b;
(5) memory module, by RAM, ROM, compositions such as FLASH;
In addition, in order to realize and the communication of this remote controller, in existing set-top box or system for TV set, need wireless telecommunications and driver module with the corresponding agreement of the built-in communication module of remote controller.
(6) video format interface or analog video format modular converter and interface.
See also Fig. 2, this figure is the typical structure framework of the utility model application system.Wherein, television system has mainly comprised tuner, demodulator, demodulation multiplexer, mpeg decoder, embedded type CPU, memory, display terminal.
The course of work of digital television receiver in the application system of Fig. 2 (set-top box or digital TV integrated machine) is specific as follows: be sent to demodulator after tuner receives high-frequency signal and carries out respective handling and carry out being output as transmission code stream after digital demodulation and the relevant treatment, transmission code stream enters the demultiplexing that demodulation multiplexer carries out transport stream and program stream, selects a certain specific program source and enters the MPEG2 decoder and carry out audio/video decoding.Decoded signal outputs to numerical display device such as panel TV or analog display device such as CRT TV through the further processing (can be to be converted to the Digital Media display format or to be encoded to analog signal) of display format.In the application system shown in Fig. 2, this transmission code stream also entered embedded type CPU simultaneously when apparatus of digital television receiving was being sent into the demodulation multiplexer demultiplexing and used for this receiving equipment after TV signal is demodulated into transmission code stream, handle this bit stream data once more by ICP/IP protocol stack and corresponding software bag, launch by built-in 802.11 (b/g/n) wireless communication module of digital television receiver afterwards.Simultaneously, it is original transmission code stream with the reduction of data that receives that remote controller in the utility model uses its built-in 802.11 (b/g/n) wireless communication module to receive and utilize its embedded CPU and ICP/IP protocol stack, this transmission code stream enters the built-in demodulation multiplexer of remote controller, solve the audio-video code stream of corresponding program according to user's selection, and be converted to exportable audio frequency and video form and output on the built-in display terminal of remote controller, thereby utilize the existing part of module function of apparatus of digital television receiving and make the remote controller in this utility model export the function of other one tunnel programme signal.Thereby realized that remote controller and television set or set-top box watch the two-way program simultaneously.
Here, it needs to be noted that for the transmission code stream of multicarrier (MCPC), the constructed system of this utility model can watch two different programs simultaneously, and, the multiplexing program in the transmission code stream of same frequency all be limited to; And for the transmission code stream of single carrier (SCPC), the constructed system of this utility model can only watch same program simultaneously, the same program in the promptly same transport stream, and this is that technical characterstic by the Digital Television multiplexing transmission is determined.
In addition, the constructed system of the utility model supports the function that another is practical, promptly by the constructed remote controller of this utility model, handle and transmit road program from apparatus of digital television receiving, the programme signal form that makes it to export can directly output to second display device.Its typical application mode is as follows:
As previously mentioned, utilize remote controller constructed in the utility model to receive and be reduced to original multiplexing code stream from the packet of apparatus of digital television receiving (digital TV set-top box or digital TV integrated machine) wireless transmission, select wherein one tunnel programme signal (for multicarrier MCPC for the multiplexing code stream demultiplexing, if the form of SCPC, the problem that does not then have selection), use the MPEG2 decoder decode to be reduced to original audio-video signal afterwards and utilize that the built-in embedded type CPU processor of remote controller is encoded to it the display format that can directly export again and exports the corresponding interface in this utility model, as DVI, HDMI etc., pass through cable, these outputs can be imported the display device that corresponding interface is arranged easily, as LCD display etc., in addition, also can in this remote controller, increase corresponding analog encoding module its decoded digital television program is converted to analog format output, as VGA, AV, S-VIDEO etc., can export in existing C RT TV or the display, thereby make the display device that does not possess the digital received function show digital television program.
