According to the self characteristic of a wireless network, the present invention adopts the most advanced H. 264 video coding algorithm, utilizes the SMIL script to describe the characteristics of the time synchronization relationship and the spatial editing relationship among media, and realizes the mobile and multipoint monitoring by the mobile streaming media server technology.
Description
Technical field
The present invention adopts the mobile flow medium technology to realize that mobile multiple spot monitors, is specifically related to video/audio encoding and decoding technique, mobile flow medium technology and SMIL technology.
Background technology
The mobile flow medium technology
The mobile flow medium technology is exactly that continuous image and acoustic information are put on the webserver after overcompression is handled, mobile phone users can be watched, listen to while downloading, and do not need whole multimedia file download by the time to finish the technology that just can watch immediately.In fact the mobile flow medium technology is the product that network audio-video technology and mobile communication technology develop into certain phase, it is to merge the technology that is produced after a lot of network technologies, and it can relate to the multinomial technology such as collection, compression, storage, transmission and network service of stream medium data.
The network transmission protocol of supporting is: real-time fluidisation agreement (RTSP), real-time transport protocol (rtp) and RTCP Real-time Transport Control Protocol (RTCP).The video coding algorithm of supporting: H.263, MPEG4 and H.264; The audio coding algorithm of supporting: AMR, AAC etc.
1, video/audio encoding and decoding technique
H.263 video coding algorithm at present commonly used in the world has, MPEG4 and H.264.Wherein H.264 compare, have following advantage with other existing video encoding standard:
Low code stream (Low Bit Rate): compare with compression technology such as MPEG2 and MPEG4 ASP, under equal picture quality, adopt the data volume after the technique compresses H.264 to have only 1/8 of MPEG2,1/3 of MPEG4.
High-quality image: H.264 continuous, smooth high quality image (DVD quality) can be provided.
Fault-tolerant ability is strong: H.264 wrong essential tool such as solving under the unstable network environment incidental packet loss is provided.
Network-adaptive is strong: H.264 network-adaptive layer (Network Adaptation Layer) is provided, has made H.264 file transmission on heterogeneous networks easily (for example the Internet, CDMA, GPRS, WCDMA, CDMA2000 etc.).
2, SMIL technology
SMIL is a synchronous multimedia integrate language, and it is a mark that a cover has provided and very simple.It is used for regulation multimedia segment (scope that comprises of multimedia has here: audio files, video file, animation, picture, literal etc.) when, somewhere, play in which type of mode.Time synchronizing relation and the space layout of adopting SMIL can describe easily between the various medium concern, be to be used for the integrated multimedia program on the Internet, especially the main language tool of Streaming Media, it can realize the title of video/audio, navigation area and electronic script three synchronously.
Have following advantage: avoid using unified containing file format, simultaneously play multimedia segment at different local (on the servers), layout, multilingual selection support, many bandwidth carried out in whole demonstration select to support.
3, video monitor
Video monitor is digital video, computer network communication technology, multimedia technology, the compress technique of uses advanced, realizes the telemonitoring of image, sound.Difference according to the signal of gathering can be divided into analog signal supervision and digital signal supervision.
Along with the development and the arrival in 3G epoch of mobile technology, carry out mobile monitoring by wireless environment and become a kind of trend.Because the mobile environment its own particularity proposes new requirement to code efficiency, network self-adapting etc., need also simultaneously to realize that split screen shows.H.264 compression efficiency is higher at present, at aspects such as low code check environment and network fault tolerances many advantages are arranged, so mobile monitoring adopts H.264 video coding algorithm; In order to realize the versatility of portable terminal, consider to utilize the split screen control of SMIL, the player of any support SMIL can both realize that remote multi-point shows.
Present existing method is: each acquisition terminal acquired signal is also carried out the video/audio compressed encoding to signal, and the code stream with compression is transferred to central monitoring position then, is presented on the terminal by the split screen technology at central monitoring position.
The shortcoming of existing method is:
1, operating personnel can only monitor at central monitoring position, can't accomplish the visit in any time, any place, can not make fast reaction to some accidents.
2, need in Surveillance center that the medium of configure dedicated receive, processing server, receive the data of acquisition terminal and data are shown.
3, need to realize that split screen shows that software for display is special-purpose, lack versatility and flexibility.
4, the general encoding and decoding technique incompatibility portable terminal that adopts and the transmission of wireless environment.
