    摘要: An adaptive buffering scheme allows more effective media transport and buffering. In one aspect of the adaptive buffering scheme, buffering parameters are adapted to different media characteristics, such as media play commands or the amount of encoding/transcoding required for the particular media stream. In another aspect of the adaptive buffering scheme, buffering is adapted to different transmission or memory conditions, such as transmission rate, packet jitter, or the amount of available buffer memory. In one example, the adaptive buffering is supported using Real Time Streaming Protocol (RTSP), and/or Real Time Transport Protocol (RTP) and associated Real Time Control Protocol (RTCP), and/or Session Description Protocol (SDP) messages.
