In an optional embodiment of the present invention, audio, video data input-output apparatus is integrated in splicing screen system.
A complete embodiment of the invention is described in detail below in conjunction with the accompanying drawings.
Fig. 2 is the structure chart according to the audio, video data input-output apparatus of present example.As shown in Fig. 2 the sound regards
Frequency data input/output device can include：Adaptation module G, wherein, adaptation module G is made up of 3 parts, is specifically included：It is defeated
Enter/output interface, transcoder T, fusion device C.A works of the adaptation module G as splice displaying system in embodiments of the present invention
Make module to be controlled by system management module M.
Transcoder T：Audio, video data is decoded and recompiled between various coded formats, for example, VGTP is arrived
H264 or H264 to VGTP etc., transcoder is interior to include various codecs, if any newly-increased coded system, as long as corresponding to addition
Codec；Fusion device C：All screen source datas in acquisition system, each picture can be carried out as needed any
Anastomosing and splicing, the voice data after fusion can also be used as a source, you can externally output, internal can also use.
The audio, video data input-output apparatus of the wherein embodiment of the present invention can apply to following 3 scenes：
(1) external source inputs：1. external system U output O4, O5 connection adaptation module G, G receive original coding audio frequency and video
Data；2. adaptation module G judges coded format according to audio, video data, data and coded format are then input to transcoder T；
3. transcoder T receives data, the codec according to corresponding to selecting coded format, data are decoded, by decoded number
Recompiled according to according to the coded format used in system, finally correspond to and be output to I4, I5；4. manager M, adapter G is controlled,
I4, I5 are input to the input processing module D of splicing screen system.External source can be completed by above-mentioned mode to input, and utilized
Adaptation module G maps external source, and external source now has no any difference with inside sources for system, and access mode is identical,
It will not be described here.
(2) inside sources export：1. manager M, inside sources I1, I2, I3 are linked into adaptation module G；2. adaptation module G will
Audio, video data is input to transcoder T, and input coding requirement；After 3. transcoder T receives data and coding requirement, first by system
Then data are encoded, are output to O1, O2, O3 by interior data decoding again according to target code form；4. external system U,
O1, O2, O3 are may have access to, realizes the access to splicing screen system endogenous I1, I2, I3.For external system U, without extra
Function is supported, with accessing other network video sources and indistinction.
(3) audio frequency and video fusion application：1. all audio-video sources that transcoder T is received can all be registered in fusion device C；2. when
When needing to carry out audio, video data fusion output, manager M notice adaptation module G, and audio frequency and video relevant parameter is sent, G will join
Number is input to fusion device C；3. fusion device C takes audio frequency and video parameter, log-on message and position, coordinate, timestamp are therefrom parsed
Etc. information；4. fusion device C obtains the data after corresponding audio/video decoding according to log-on message out of transcoder T；5. fusion device
C is merged each audio, video data according to position, coordinate, timestamp information；6. fusion device C transfers to the data after fusion
Transcoder T is encoded, and the data after coding return to C；7. fusion device C is using the data after coding as output X6.Here melt
Clutch C output can splicing is internal to be used, for example, record screen, console picture echo etc., can also be supplied to external system
U is used, for example, giant-screen picture is remotely launched, multichannel is fused into launches again all the way, reduces bandwidth occupancy, the utilization of resources is more
Rationally.
In audio, video data input-output apparatus provided in an embodiment of the present invention, by adding a general adaptation
Module, as unified external audio frequency and video input/output module, any several pictures can be fused into all the way, it is internal or right
Outer use, convenient and swift and external system UNICOM, solves islanding problem.The adaptation module is logically independent, with splicing
System communication uses standard network communication technology, can very easily be integrated into existing splicing system.Internally access outer
Portion source and external output picture are simple, if two independent splicing screen systems need to access video sources mutually, if all had
The adaptation module, then it need not add any additional functionality, you can resource-sharing.If other do not possess the system of the adaptation module
Need to be connected with the system, the system only needs the coded format support corresponding to addition in transcoder.
In addition, the system is when accessing external system source, because being mapped to the system in fact by source during adaptation module
It is interior, difference is had no with the source in the system during access, therefore is not present that network, hardware etc. is various to limit presence.
Meanwhile adaptation module can be mixed each picture using fusion device because possessing all data sources, formed
One complete large-size screen monitors audio frequency and video picture, can also select certain several source to be mixed into all the way, picture can be used for this and be
Picture control terminal of uniting echo, or recorded broadcast storage is carried out, can also externally it export；The way of output is external with other sources of the system
Export and indistinction, external system can have access to the source that all the system externally provide by a kind of mode.
According to embodiments of the present invention, there is provided a kind of embodiment of the method for audio, video data input/output method is, it is necessary to say
It is bright, it can be held the step of the flow of accompanying drawing illustrates in the computer system of such as one group computer executable instructions
OK, although also, show logical order in flow charts, in some cases, can be with different from order herein
Perform shown or described step.
Fig. 3 is the flow chart of audio frequency and video input/output method according to embodiments of the present invention, as shown in figure 3, the audio frequency and video
Data input/output method comprises the following steps：
Step S302, receive audio, video data to be entered and/or audio, video data to be output.
Step S304, determine the coded format of audio, video data to be entered and/or the coding lattice of audio, video data to be output
Formula.

Code processing, and/or, audio, video data to be output is carried out at transcoding according to the coded format of the audio, video data to be output of determination
Reason.
Step S308, the audio, video data to be entered after progress transcoding processing is subjected to input processing；And/or it will carry out
Audio, video data to be output after transcoding processing carries out output processing.
Pass through above-mentioned steps, it is possible to achieve any several portraits are fused into all the way, internally or externally used, it is convenient and swift
Ground carries out UNICOM with external system, relative to of the prior art when carrying out UNICOM with external system, due to for different
Coded format needs to develop corresponding translation function, and caused development process is complicated, in addition, external system makes in internal system
Used time is limited larger by network bandwidth, also results in external system when being conducted interviews by network, carries out multicopy broadcasting
When limited by network bandwidth it is larger, or even can not carry out picture replicate play the drawbacks of, realize inter access external resource
And externally the output relatively simple purpose of picture, the technology for having reached conveniently and efficiently realization and other systems resource-sharing are imitated
Fruit, and then solve progress built-in system audio, video data in correlation technique and interacted in the audio, video data with external system
