A kind of method of acoustic-video multi-way separate screen decoding, it occurs in more than the acoustic-video multi-way separate screen decoding system media decodes divides in the screen equipment, may further comprise the steps:
1) operation signal and the user who utilizes the signal communication module to receive from user's display terminal asks, and more described operation signal and user's request passed to the encoded authentication module;
2) utilize the encoded authentication module that the authentification of user judgement is carried out in the operation signal and the user's request that receive,, submit to corresponding multi-medium data to give the audio/video decoding module operation signal and user's request by authentication;
3) utilize operation signal that the audio/video decoding module receives and user's request to multi-medium data compress, ordering and Play Control handle, the audio, video data after will handling again asks to submit to the multi-channel separate screen module with relevant operation signal and user;
4) utilize the multi-channel separate screen module that relevant operation signal and user's request are carried out split screen, comprising:
A) inquire about available maximum split screen number earlier automatically;
B) determine the delivery outlet of requesting terminal subsequently, return can split screen signal;
C) carrying out split screen handles, audio, video data and the end message that to from the audio/video decoding module, receive, generate a split screen signal, and write the authentication information of each display terminal, finally break into a packets of information and send to the encoded authentication module according to the resolution sizes of setting;
D) the encoded authentication module authenticates after receiving split screen signal, audio, video data bag and authentication information again, to send split screen by the signal communication module by split screen signal, audio, video data bag and the corresponding terminal information of authentication at last, finish the transmission of information and data.
The invention has the beneficial effects as follows: native system is shown as the basis with double screen, with DSP (digital signalsprocessor) for replenish audio frequency and video are encoded after, be pushed to many VGA displays, television set or DVI digital plane display by a PC simultaneously by the selectable split screen of the operation requests of terminal, this multihead display is not that simple a plurality of display device shows a plurality of identical contents, but show different separately pictures on a plurality of screens, but and the big picture of the combination of display splicing.Mouse and window can also move at each screen internetwork roaming, and need not any change of software.Native system has been finished the construction of home entertainment center with low cost, and friendly easy-to-use user interface is arranged, and good additional function extendibility, and manipulates mode easily.

Embodiment
As shown in Figure 1, present embodiment acoustic-video multi-way separate screen decoding system comprises:
One multimedia decoding divides screen equipment 1, and it is core of the present invention, is made up of signal communication modules A, encoded authentication module B, audio/video decoding module C and multi-channel separate screen module D.
One ordinary PC 2, it divides screen equipment 1 to cooperate with multimedia decoding and forms the central server with DSP function, an exercisable platform also is provided simultaneously.
Some user's display terminals 3, these terminals can be selected common TV, display, monitor etc., can form a group among a small circle by different display devices, and these displays can show different pictures at one time.Signal receiving module is housed on the display terminal, is used to receive audio/video flow signal and the control signal that multimedia decoding divides screen equipment 1 to send; Signal transmitting module also is housed on the display terminal, is used for dividing screen equipment 1 to send interactive signal to multimedia decoding.
Constitute some intermediate conveyor equipment that also have of native system, as: cable 4, it couples together center-side and user side in wired mode; Remote controller, it is wirelessly center-side and user side to be coupled together.
As shown in Figure 2, described multimedia decoding divides signal communication modules A in the screen equipment 1 to be used to realize that signal between branch screen equipment and PC and each user's display terminal is mutual and handles; Encoded authentication module B is used to realize the transmission of reception, processing and the machine code of signals such as various wireline interfaces and various wireless protocols; Audio/video decoding module C is used to provide the high-quality decode procedure of multiple audio/video flow; Multi-channel separate screen module D is used to finish the split screen process of a plurality of display terminals.
