Method and Apparatus for the RTP Send Payload Handler to Send Video Stream

摘要

PURPOSE: A system and a method for handling RTP transmission payload for transmitting a video stream with RTP are provided to transmit a video stream, output from a video CODEC filter of a video transmission system, in RTP suitable for real-time transmission. CONSTITUTION: An RTP transmission payload handler system includes a video stream receiver(201), an RTP payload generator(202), a transmission buffer manager(203) and a filter interface(204). The video stream receiver receives a video stream output in the unit of video object. The RTP payload generator divides the video stream into video streams each of which has the payload size of RTP packet to store the divided video streams in a transmission buffer and generates an event informing that the transmission buffer is filled with data. The transmission buffer manager generates and manages a buffer for temporarily storing the data processed by the RTP payload generator before the data is transmitted. The filter interface provides various functions to allow an RTP transmitter(210) to operate the result processed by the transmission buffer manager.
