To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained on the premise of creative work is not made belongs to the scope of protection of the invention.
The embodiment of the present invention one：
Fig. 1 be VDI scenes of the present invention under dynamic select audio compression algorithm an embodiment of the method flow chart, as shown in figure 1, this method can include：
5101st, the map listing of server placement algorithm selection parameter information and correspondence audio compression algorithm title；
It should be noted that what algorithms selection parameter information represented is process name, or audio format, or process name and audio format.
5102nd, acquisition algorithm selection parameter information, is compressed according to parameter information and map listing selection audio compression algorithm；
Whois lookup map listing, if parameter information is process name or audio format, and map listing includes the process name or the audio format, then obtains process name or audio format correspondence the audio compression algorithm title on the map listing.
If parameter information is process name and audio format, and map listing includes the process name, then searches the map listing according to the process name, obtains process name correspondence audio compression algorithm title on the map listing；If the map listing does not include the process name, searched and reflected according to audio format
List is penetrated, the audio format correspondence audio compression algorithm title on map listing is obtained.
S103, the audio compression algorithm title of the transmission selection are to client, so that client selects decompression algorithm corresponding with the audio compression algorithm to carry out decompression operation.
It should be noted that, client first receives selected audio compression algorithm title, and the voice data after the compression received after, select decompression algorithm corresponding with the audio compression algorithm to carry out decompression operation to the voice data.Here, be sent to client can also be not limited to audio compression algorithm title or algorithm index, the audio compression algorithm information such as algorithm sequence number.
The method provided by the present embodiment, server can be carried out audio compression with dynamic select audio compression algorithm and send audio compression algorithm title to client under VDI scenes.The problem of solving what server in the prior art was compressed using fixed-audio compression algorithm, and cause that targetedly Consumer's Experience can not be met.The flexibility of server process audio application is improved, Consumer's Experience is improved.The embodiment of the present invention two：

The parameter information can determine that application program is that tonequality requires a high, class not high to delay requirement or less demanding, high to the delay requirement class of tonequality.Such as, the entitled skype.exe of the process of application program, then it is assumed that the application program is less demanding to tonequality but to delay requirement height.If the entitled mp3player.exe of program process, think that the application program requires tonequality high not high to delay requirement.
5205th, server selects audio compression algorithm according to selected program process name and audio format information；
Because program process name and audio format are two kinds of parameter informations, it is therefore desirable to determine the height of priority to select corresponding compression algorithm.In the present embodiment, the priority of process name is higher than the priority of audio format, and server first selects audio compression algorithm according to program process name, comprised the following steps that：
According to program process name information searching map listing, corresponding compression algorithm is found；If searched less than the process name information, according to audio format information searching map listing, corresponding compression algorithm is found；If process name and audio format be not inside map listing, the fixation compression algorithm of acquiescence is selected.Wherein, the fixation compression algorithm of acquiescence is that server is pre-configured with.
5206th, after server chooses audio compression algorithm, compression algorithm title is sent to client；
Server sends compression algorithm title to client, it is therefore an objective to allow client to carry out the preparation decompressed using the corresponding decompression algorithm of the compression algorithm.
S207, server select the compression algorithm to be compressed voice data, and send the voice data after compression to client.
S208, client carry out decompression to the voice data stream after compression and contractd broadcasting.
After voice data after the compression that the compression algorithm title and step S207 that client receives step S206 transmissions are sent, select the corresponding decompression algorithm of the compression algorithm, voice data after compression is decompressed, audio played out after the completion of decompression.
The method for the dynamic select audio compression algorithm that the present embodiment is provided, searches map listing according to the process name of selected application program and audio format and selects audio compression algorithm.Solve can not dynamic select audio compression algorithm the problem of, improve the flexibility of server process audio application, improve Consumer's Experience.

In the present embodiment, under VDI scenes, server is as follows according to the flow of audio format dynamic select audio compression algorithm：
S301-S303 is with step S201-S203;
S304, server obtain audio format information；
Server is received after request message, starts the application program selected by client, and obtain the audio format information of selected application program.
In addition, server can also obtain the process name information of application program, the parameter is sent to compression algorithm selecting module.For process name and audio format this two category information, server need to only obtain one of which.
S305, server select audio compression algorithm according to algorithms selection parameter information and map listing；Server searches corresponding audio compression algorithm according to audio format, audio format and audio compression algorithm be inside map listing --- mapping relations, if can not find the audio format inside map listing, the fixed-audio compression algorithm of acquiescence is selected.Wherein, the fixed-audio compression algorithm of acquiescence is that server is pre-configured with.
Same S206-208 of S306-S308.
The method for the dynamic select audio compression algorithm that the present embodiment is provided, searches map listing according to the audio format of selected application program and selects audio compression algorithm.Solve can not dynamic select audio compression algorithm the problem of, improve the flexibility of server process audio application, improve Consumer's Experience.
