Technical field
The present invention relates to a kind ofly, realize the video-mail module of mobile phone terminal video-mail Video Mail transfer function belonging to information technology based on H.264 compress technique and real-time streaming protocol RTSP/ realtime transmission protocol RTP.
Background technology
In recent years, the short message service SMS development in the information transmission technology is very fast, and the common short message of mobile phone has obtained using quite widely.Simultaneously, along with the success of GPRS GPRS, the popularizing of the release of data service and colour screen handset, simple text information can not be met consumers' demand fully, and then multimedia application becomes a kind of trend gradually, such as transmitting information such as video, picture, animation and sound.Therefore, the professional MMS of multi-media SMS arises thereupon.But in multi-media SMS transmitted, owing to be subjected to the restriction of the network bandwidth and mobile phone terminal memory capacity etc., the short message content that transmits in the multi-media SMS MMS system can only be picture, sound and literal at present, and file size also is limited in the 50K bit capacity.Limited the transmission of mobile video mail Video Mail greatly.If use mobile video mail Video Mail system, then be different from the professional MMS of multi-media SMS, the user can receive and dispatch video-mail at mobile phone terminal, Mail Contents leaves on the special-purpose streaming server, when receiving mail, portable terminal adopts real-time streaming protocol RTSP/ realtime transmission protocol RTP to carry out streaming and plays, and need not Mail Contents all is downloaded to the terminal internal memory, and the big young pathbreaker of mail is not subjected to the restriction of terminal storage capacity.In addition, in mobile video mail Video Mail, adopt the H.264 compress technique of high compression rate, under the narrow bandwidth network condition, video file still can obtain smooth playing.The present invention is directed to above demand, development provides on a kind of mobile phone terminal, based on the video transmission module of compress technique and real-time streaming protocol RTSP/ realtime transmission protocol RTP H.264, can realize mobile video mail Video Mail transfer function.
Summary of the invention
The objective of the invention is, based on H.264 compress technique and real-time streaming protocol RTSP/ realtime transmission protocol RTP, add the video transmission module at mobile phone terminal, thereby realize mobile video mail Video Mail transfer function, for the cellphone subscriber provides a kind of abundant in content, the multimedia mail service that flexibility and real-time are stronger.
Design framework of the present invention is to add video-mail Video Mail module at mobile phone terminal.Module is implanted video compression algorithm H.264, audio coding and based on the internet protocol IP protocol stack of real-time streaming protocol RTSP/ realtime transmission protocol RTP G.722, realizes by dual mode:
One, utilizes personal digital assistant PDA high-performance processor and embedded OS, terminal real time codec software directly is loaded in the personal digital assistant PDA high-performance processor moves.
Two, under the indifferent situation of regular handset processor, for satisfying H.264 and the G.722 audio/video encoding/decoding performance requirement of streaming in playing, add the coprocessor that is specifically designed to the audio/video encoding/decoding processing at mobile phone terminal, hardware-accelerated as high speed digital signal processor DSP realization, improve result of broadcast.During concrete enforcement, software and hardware and mobile phone terminal in the video-mail Video Mail module are integrated, by the memory interface of mobile phone terminal, the realization video module is communicated by letter with the mobile phone terminal system.In the operating handset, the running of software control video module.Camera, display screen, the original configuration of the multiplexing regular handset terminal of speech input output device.In addition, add the mobile phone of video-mail Video Mail module of the present invention, also can in the mobile network, set up the dedicated stream server, services such as the storage forwarding of video-mail and video request program are provided by third party content supplier.
The advantage of mobile video mail Video Mail module of the present invention is, use mobile video mail Video Mail system, the user can receive and dispatch video-mail at mobile phone terminal, Mail Contents leaves on the special-purpose streaming server, when receiving mail, portable terminal adopts real-time streaming protocol RTSP/ realtime transmission protocol RTP to carry out streaming and plays, and need not Mail Contents all is downloaded to the terminal internal memory, so the mail size is not subjected to the restriction of terminal storage capacity.In addition, in mobile video mail Video Mail, adopt the H.264 compress technique of high compression rate, under the narrow bandwidth network condition, video file still can obtain smooth playing.Thereby for the cellphone subscriber provides a kind of abundant in content, the multimedia mail service that flexibility and real-time are stronger.
