Streaming media transmission architecture method based on SIP protocol

Abstract

The present invention discloses a streaming media transmission architecture method based on SIP protocol, the method comprises point-to-point transmission and point-to-multipoint transmission, also includes openH264 encoding, Packsize, payload, RIP encoding, UDP encoding, etc.. During point-to-point transmission, the sender's camera image data is encoded by openH264 to obtain H264 data, images ofeach frame are packed into multiple payloads after Packsize, and then the RIP encoding is used to add a timestamp to the packaged payload, and is sent to the User2 (receiving end) through the UDP encoding, and a UDP header and a RTP header are removed from the data at the receiving end to obtain the payload and enter into a jitterbuffer for caching. In the method, the user can make a video call, if multiple people need the video call at the same time (one-to-multiple), two options are available to choose from, one is to use RTP distribution to solve a small number of multi-user calls, and theother is to use a streaming media server for multi-user video calls.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a streaming media transmission framework method based on the SIP protocol. Background technique [0002] Life in the new era has gradually become inseparable from the Internet. Through the Internet, people can make video calls, watch football games, order TV dramas, and view video surveillance, and the information transmission between people has gradually turned to audio, video, and individual Text messages can no longer meet people's needs. Video calls, streaming video viewing, etc. are loved by more and more users, allowing users to experience the best video playback experience in the shortest time, the improvement of network bandwidth and The rapid development of audio and video coding technology has promoted the application of streaming media to all walks of life in the Internet world.

[0002] Life in the new era has gradually become inseparable from the Internet. Through the Internet, people can make video calls, watch football games, order TV dramas, and view video surveillance, and the information transmission between people has gradually turned to audio, video, and individual Text messages can no longer meet people's needs. Video calls, streaming video viewing, etc. are loved by more and more users, allowing users to experience the best video playback experience in the shortest time, the improvement of network bandwidth and The rapid development of audio and video coding technology has promoted the application of streaming media to all walks of life in the Internet world. However, most streaming media systems on the market currently have single functions and cannot integrate video calls, live broadcasts, on-demand, and video surveillance into one In a system, there are hundreds of other video surveillance camera manufacturers, and the systems of various camera manufacturers cannot be shared.
