Description
Technical field
The utility model relates to information technology, particularly a kind of method that transmits the equipment of audio and video stream media and transmit audio and video stream media.
Background technology
In the prior art, the fast development of the expansion of development of internet technology, the network bandwidth and multimedia technology and the Internet, the real-time Transmission of digital audio/video becomes a focus of computer realm research.Traditional analog signal is owing to poor anti jamming capability is unfavorable for transmission, and digital video signal can overcome this shortcoming, but the raw digital video of gathering exists the video information data volume huge in transmission course, and the characteristics that delay-sensitive is strong are unfavorable for the transmission under bandwidth environment.Therefore, must compress, make in real-time Transmission, can keep lower delay original video data.Along with people propose in succession to the surge of video image demand and various image and the new compression standard of video, as MPEG2, H.263, MPEG4 and H.264 waiting.Along with the demand in market, under alap storage condition, obtain two hang-ups that good picture quality and the quick transmission of low bandwidth image have become video compression.H.264 IEO/IEC/ and ITU-T two big International Standards Organization have jointly formulated video compression standard of new generation for this reason.
H.264 the standard with former is the same, also is the hybrid coding pattern that DPCM adds transition coding.But it adopts the compact design of " returning basic ", and option that need not be numerous obtains the compression performance more much better than MEPG-4; H.264 strengthened adaptive capacity, adopted the structure and the grammer of " network close friend ", helped the processing of packet loss various channels; H.264 application target wider range can satisfy different rates, different resolution and the different demand of transmitting (storage) occasions.Further, the high accuracy of H.264 encoding, multimodal Displacement Estimation are based on 4 integer transforms, layered encoded grammer etc.These measures make that H.264 getting algorithm has very high code efficiency, under identical reconstructed image quality, and can be than the code check of H.263 saving about 50%.H.264 code flow structure network-adaptive is strong, has increased error resilience, can adapt to the application of IP and wireless network well.H.264 can transmit video flowing with lower data rate, the aspect such as lose, surmount existing MPEG-2, MPEG-4 and video communication standard H.26x, be more suitable for narrow band transmission at video quality, compression efficiency and data packet recovery based on networking protocol (IP).
At present; the software of the H.264 encryption algorithm of Zhi Chiing and device are also few fully; H.264 the software and the device great majority of algorithm are also only supported H.264 Baseline with regard to having declared to use at last; and most also can only by the user a privately owned player be installed on personal computer and watch real-time video recording by embedded web page server; because compatible problem; a lot of users fail on the different web browser of version this player to be installed and can not see video, also cause system can only change development on a small scale in addition.
Summary of the invention
For solving the technical deficiency of said method, the invention provides a kind of audio and video stream media RTMP pusher and based on the RTMP audio and video stream media method for pushing of this device, by obtaining the control of audio frequency and video input equipment, obtain and use H.264 that main and high profile standard compress and encode behind the audio-video signal, the audio frequency and video behind the coding use the RTMP stream protocol to encapsulate and be pushed to the RTMP streaming media server.
The alleged audio and video stream media RTMP pusher of the present invention comprises audio frequency and video source, audio-video collection and modular converter, H.264 coding module, RTMP agreement realize module and network communication module; The input of audio-video collection and modular converter has one or more in CVBS, DVI, HDMI, the rgb video interface, connect by the audio frequency and video source of this input with the outside, the output of audio-video collection module and modular converter is connected to the input of coding module H.264, H.264 the output of coding module is connected to the RTMP agreement and realizes module, and the RTMP agreement realizes that module is connected to network communication module.
The alleged RTMP audio and video stream media method for pushing of the present invention may further comprise the steps: audio-video collection and modular converter pass through to obtain the control of audio frequency and video source and audio/video flow, thereby obtain corresponding audio-video signal; Audio-video signal through noise reduction, go interlacing to handle after, transferring to audio, video data H.264, coding module carries out compressed encoding; H.264 data behind the coding are transferred to the RTMP agreement and are realized that module encapsulates according to the stream protocol of RTMP; RTMP data flow after it is characterized in that encapsulating is carried out transfer of data by network communication module with the RTMP streaming media server on push mode and the Internet; This push mode is the plug and play pattern, and it at first makes the RTMP streaming server on RTMP data flow and the Internet obtain the passage of shaking hands and setting up a transfer of data, immediately the RTMP data flow is pushed to the RTMP streaming media server incessantly.
The peculiar Streaming Media push mode of the present invention is exactly that audio, video data is automatically delivered to user's technology in front, promptly realizes " audio, video data is looked for the user ".In the Streaming Media push mode, node is transmitted or storage after receiving data immediately, therefore the less and father node of transmission delay need not to have fixing IP or domain name between node, the stream push technology has changed audio frequency and video access modes on the Internet, will search audio frequency and video and become and on purpose receive audio frequency and video.This has not only changed the direction that audio frequency and video flow, and has reduced the load of the Internet by the minimizing of audio frequency and video flow.Its advantage is as follows: (1) encoder setting flexibly; (2) the encoder dynamic IP gets final product; (3) seamless link; (4) lasting stream transmission; (5) effectively utilize bandwidth; (6) encoder and streaming server are connected naturally; (7) advice method is flexible; (8) fail safe is good; (9) I P protocol groups is classified to Useful Information and is managed, and broadcasts with fixing channel, can greatly improve the degree of audio/video flow development and use and the dynamics of management.
The present invention suits to use in the occasion that all on-the-spot phonotape and videotapes such as theatrical performances, athletic competition, Web conference are relayed.
