Abstract

The embodiment of the invention discloses a transfer processing method and a transfer processing system for a multi-channel real-time streaming media file, and a receiving device. The method comprises the following steps of: receiving data packets on L streaming media channels by a client side in a way of aiming at a same streaming media program, wherein the system clocks of N streaming media servers are consistent; when a time variable phi is a nonblank value, recognizing whether timestamps TS on the data packets are more than the sum TC+phi of the current system moment TC of the client side and the time variable phi or not; if the timestamps are not more than the sum, abandoning the data packets; if the timestamps are more than the sum, storing the data packets in a corresponding buffer area playing queue according to a sequence from a small one to a big one of the timestamps TS; and when the TC+phi reaches the timestamp TS on a first data packet in the playing queue, decompressing, decoding and playing the data packets in the playing queue in sequence. According to the embodiment of the invention, the synchronous playing of the real-time streaming media files transferred in a multi-channel way can be realized, and the situation that a plurality of frames are asynchronous is avoided.

Description

technical field [0001] The invention relates to streaming media technology, in particular to a method and system for transmitting and processing multi-channel real-time streaming media files, and a receiving device. Background technique [0002] Streaming media refers to media formats played on the Internet (Internet) or Intranet (Intranet) in a streaming manner, such as audio, video or multimedia files. Streaming transmission mainly means that the streaming media server parses the entire audio / video (Audio / Video, hereinafter referred to as: A / V), three-dimensional graphics (hereinafter referred to as: 3D) and other streaming media files into a specific compression method. Compressed packages are transmitted sequentially and in real time to the client, usually the user's computer. The user computer first creates a buffer, and does not download the entire streaming media file before playing the streaming media file, but only downloads the beginning part of the streaming medi...
