| Today, streaming media technology has become a part of the network's hottest, it greatly improves and enriches people's lives for the senses network experience.Indeed, the audio and video compression coding technology as one of the most critical streaming media system, which will have a direct impact on the performance and quality of the data stream.China has independently developed the audio and video codec standard AVS, compared with MPEG, H.264 / AVC codec standards, etc., with advanced technical performance, low complexity, intellectual clarity, etc., so that its industrial prospects are bright.On the base of analyzing the basic principle of streaming media, application status, flaws and shortcomings, combined with our own intellectual property AVS standard, compared AVS and MPEG, H.264 and other mainstream audio and video codec compression standard technical features,focus on, including codecs, intra-inter prediction, transform and loop filter key technologies such as AVS. The use of RTP / RTCP / RTSP and other protocols designed and developed to support AVS standard streaming media systems, streaming media system by the service and client composition, the paper gives a streaming media system AVS algorithm, network communication, data codecs, data design transmission and other core components of the player.Through the actual use test AVS algorithm simulation and comparison of the results of streaming media systems, indicating achieve a media system design and meet the requirements, but also further validate the efficiency and practicality of AVS algorithm.Design and implementation of streaming media system can be applied to related fields VOD, video surveillance, and has broad application prospects.The AVS video coding our own intellectual property system for streaming media, not only reflect AVS simple and efficient, and can be very good to pro mote the development of innovative audio and video coding industry to improve its competitiveness in the international arena. |
