MULTICHANNEL VIDEO STREAM CONTROL SYSTEM AND METHOD BASED ON DSP

摘要

A multichannel video stream control system and method based on a DSP. The system corresponds to the method on a one-to-one basis. The method comprises: receiving decoding data, and storing same with a decoding channel and a chain table; configuring the decoding channel, an encoding channel and buffer allocation; receiving the decoding data stored in the decoding channel and performing scaling and overlaying; transmitting a decoded data frame; and releasing data of the data frame and a buffer cache. According to the system and the method, the number of channels of single board video is increased, the price of hardware is reduced, and the difficulty in development is reduced.
