Abstract
The invention discloses a video deformation implementation method based on a media server, and the method can provide a video deformation service for the user without increasing the prior configuration and the cost of the media server and better meet the user demand. The method includes the following steps: (a) the user sends a video deformation service request to the media server through a terminal; (b) after receiving the video deformation service request, the media server makes a video deformation parameter consultation with the terminal after judging whether the terminal can use the video deformation service; (c) the user sets the video deformation parameter consulted through the terminal which sends the parameter set by the user to the media server; (d) the terminal sends the video frame data flow to the media server which makes a deformation processing to the video data after receiving the video data; or the media server sends the processed video data to the terminal after making the deformation processing to the video data.

Further, said method also can have following characteristics: described step (b) further comprises: after (b-1) described media server is received the video distortion service request, the user is carried out authentication, authentication is carried out next step by the back; (b-2) media server judges according to current resource operating position whether described terminal can use the video distortion business, if carry out next step, otherwise return the video distortion request failure message to terminal; (b-3) media server and terminal are held consultation, and media server sends current all video distortion parameters that it is supported to terminal, after terminal is received these parameters are confirmed.
Further, said method also can have following characteristics: described video distortion parameter comprises following one or more combination: coded system, video image size, code check, video distortion mode.
Further, said method also can have following characteristics: in described step (c), described media server carries out validity checking to described parameter after receiving the parameter of user's setting that described terminal sends, after inspection was passed through, described media server returned checking to described terminal and passes through message.
Further, said method also can have following characteristics: in described step (d), described terminal sends video requency frame data stream to media server, described media server carries out deformation process to video data after receiving video data, further comprises: (d-1) described terminal sends video requency frame data stream to media server; (d-2) after described media server is received video data, video data is decoded, and the deformation parameter that is provided with according to the user carries out deformation process; (d-3) judge whether the time that the media server video distortion is handled arrive the default time, and perhaps whether video data sends and finish, if then stop video distortion and handle or video record, otherwise return step (d-1).
Further, said method also can have following characteristics: in described step (d-2), described media server after video data is carried out deformation process compresses the coding video data after the deformation process.
Further, said method also can have following characteristics: in described step (d), described media server carries out again the processed video data being sent to described terminal after the deformation process to video data, further comprise: (d '-1) described media server is decoded to video data, and the deformation parameter that is provided with according to the user carries out deformation process; (d '-2) described media server sends the video data of having handled well to terminal; (d '-3) judge whether the time that the media server video distortion is handled arrive the default time, and perhaps whether video data sends and finish, if then stop video distortion and handle or video playback, otherwise return step (d '-1).
Further, said method also can have following characteristics: in described step (d '-1), described media server after video data is carried out deformation process compresses the coding video data after the deformation process.
Involved in the present invention a kind ofly realize the method for video distortion, can better meet user's demand not increasing under existing configuration of media server and the condition of cost to the user provides the video distortion service based on the media server in the next generation network.
Description of drawings
Fig. 1 is present embodiment is realized video distortion based on media server a video record flow chart;
Fig. 2 is present embodiment is realized video distortion based on media server a video playback flow chart.
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
The present invention is based on media server and realize that the method for video distortion comprises video record flow process and video playback flow process, is that example describes with the video record flow process below, as shown in Figure 1, may further comprise the steps:
The user can connect by various forms of terminals such as computer, portable computer, personal digital assistant or mobile phone and media server.
Described parameter comprises coded system, video image size, code check and video distortion mode etc., and both sides have just carried out the preparation of video distortion service after consensus with regard to video parameter.
The validity checking of parameter is based on the protection mechanism of media server, and media server is in order to prevent illegal parameter setting to the inspection once more of these parameters.
When video playback, when needs are done the video distortion processing, also adopt and the similar method of above step, just data flow has become rightabout, referring to Fig. 2, media server earlier to the video data that will play decode, distortion, encoding compression, then video data is sent to user terminal.
Should be appreciated that, under the prerequisite that does not deviate from essence of the present invention or substantive characteristics, the present invention can implement in many ways, so unless otherwise indicated, above-mentioned exemplifying embodiment is not limited by any details of above stated specification, on the contrary, should do the understanding of broad sense in the spirit and scope that claims limited, therefore, those fall into institute in the claim scope and change or revise or equivalent that this scope is interior all is overwritten by the appended claims.
