The invention discloses a mobile video code stream customizing device and a method applied to a mobile video monitoring system, which utilizes a video receiving module, a video division module, a protocol session module, a protocol analysis module and a video transcoding module to realize user-defined mobile video code stream, so that the user can move the video data satisfying requirements to obtain satisfied video monitoring effect and can effectively ensure further development of the video monitoring service.
Description
Technical field
The present invention relates to the video monitoring technology, be meant a kind of mobile video code stream supervising device and method especially.This device and method can be provided with the mobile video code stream that oneself needs for the user, obtains video monitoring effect satisfactory for result.
Background technology
Along with the arrival in 3G epoch, the video monitoring industry is experiencing once and is changing in quality, and video monitoring service has extended to wireless network mode from traditional fixed network pattern.By mobile video monitor system, the user as monitor client access fixed network video monitoring platform, shares the monitor video resource of fixed network with mobile phone terminal.
In order to realize that mobile phone terminal monitors in real time, must in the fixed network video monitoring system, dispose transcoding server, will be from the video code flow of fixed network, convert to and be fit to the mobile video code stream that wireless network transmissions and mobile phone terminal are play.As resolution is higher, being adapted at high bit-rate video code stream that pc client plays, to convert resolution to lower, is adapted at the low code check mobile video code stream that mobile phone terminal is play.
Play in order to adapt to wireless network transmissions and mobile phone terminal better, transcoding server will have configuration management function, allows the user that parameters such as the resolution of mobile video code stream, frame per second, code check are preset.As publication number is that CN1812364 patent of invention " intelligent code-transferring method and the equipment that are used for mobile video monitor " has just proposed a kind of transcoding server with configuration management function.
Yet, important component part as mobile video monitor system, transcoding server must manage and dispose by the professional, that is to say, the mobile video code stream of transcoding server output is just remaining unchanged substantially through the configuration back, can't be at any time change according to the variation of wireless network and mobile phone terminal, thereby make the mobile subscriber under the situation that meets default mobile video code stream, mobile video monitor effect preferably can be arranged, in case running into the wireless bandwidth of location reduces, or degradation reason under the mobile phone decoding capability, the mobile video monitor effect will be had a greatly reduced quality.Moreover, to some high-end customers, even have powerful mobile phone terminal, but because the mobile video code stream of being accepted restriction also can't obtain better mobile video monitor effect.
Therefore, the single output code flow of transcoding server has limited the individual demand of mobile video monitor at present, has reduced mobile subscriber's satisfaction, has hindered the sustainable development of mobile video monitor.
Summary of the invention
In view of this, the objective of the invention is to propose a kind of mobile video code stream customizing device and method that is applied to mobile video monitor system, this device and method is given the mobile subscriber with the configuration management function of transcoding server as a kind of professional opening, is customized the mobile video code stream of transcoding server output by the mobile subscriber.

Step 5, monitor supervision platform carries out transcoding according to configuration to target monitoring point video data, and transcoding comprises conversion, resolution conversion, frame per second conversion, the code check conversion from large to small from large to small from large to small of coded format.
Step 6, the video code flow of monitor supervision platform after portable terminal sends transcoding.
More particularly, described method comprises the steps:
The first step, the mobile subscriber determines acceptable mobile video code stream parameter according to the decoding capability and the current network conditions of mobile phone terminal, comprises coded format, resolution, frame frequency, code check etc.
In second step, the mobile subscriber to monitor supervision platform request target control point video, send mobile phone terminal acceptable mobile video code stream parameter on simultaneously by mobile phone terminal.
When locating (Real Time Streaming Protocol UniformResource Locator by flowing the service agreement unified resource in real time, when RTSP URL) asking video, mobile video code stream parameters such as target monitoring point ID and coded format, resolution, frame frequency, code check are sent on can being undertaken by expansion RTSP URL.
In the 3rd step, monitor supervision platform is resolved the video request of mobile phone terminal, obtains target monitoring point and mobile video code stream parameter, and the mobile video code stream parameter comprises coded format, resolution, frame frequency, code check etc.
In the 4th step, monitor supervision platform carries out the transcoding parameter configuration according to the mobile video code stream parameter to the video code conversion module.
In the 5th step, monitor supervision platform is to target monitoring point request video, receiving target control point video data.
The 6th step, monitor supervision platform carries out transcoding according to the transcoding parameter configuration to target monitoring point video data, convert to and meet mobile phone terminal acceptable mobile video code stream, transcoding comprises conversion, resolution conversion, frame per second conversion, the code check conversion from large to small from large to small from large to small of coded format.
In the 7th step, monitor supervision platform sends standard compliant mobile video code stream to mobile phone terminal.
In the 8th step, the mobile subscriber can not meet the demands as finding the mobile video code stream that is received, and can reset the mobile video code stream parameter, repeats above-mentioned steps.
To sum up, can obtain satisfied video monitoring effect by self-defined mobile video code stream, for mobile video monitor provides a new custom service, effectively promote the sustainable development of mobile video monitor business simultaneously by mobile subscriber of the present invention.
