摘要
视频数据的采集是实时视频编码系统中的主要任务之一,视频数据的采集机制决定着整个系统的性能.在研究了实时视频采集、编码和传输系统的特点后,针对Blackfin媒体信号处理器的硬件资源,提出了采集、编码、传输并行处理的方法,设计了一种实用、高效的视频数据采集机制.该机制已成功地应用于笔者基于Blackfin533开发的H.263和MPEG-4实时视频编码系统中,以及基于Blackfin561开发的H.264编码系统中.
The capture of video data is the crucial task in real-time video coding system,and the capture mechanism determines the performance of system.After research of the real-time capture,coding and transmission device,we put forward a parallel processing method.In addition,we designed a practical and high-efficiency capture mechanism according to the characteristics of Blackfin media DSP.As a result,the mechanism has been utilized in the real-time H.263 and MPEG-4 video coding system based on Blackfin 533 and H....
