摘要
介绍了一种以DSP为核心的数字式电视跟踪系统,主要研究了利用FPGA控制、处理数字视频信号的方法,实现了实时的视频叠加。详细讨论了FPGA的控制逻辑及其相关部分结构。采用FPGA实现视频显示信息的叠加,可有效减轻DSP的速度压力,提高系统性能。
In TV Tracking system based on DSP, FPGA is used as a OSD(on_screen_display)unit. It appends the date embedded to video date came form DSP video-port. The over-all TV tracing system structure ,the software and hardware part referred to video output is introduced . The method using FPGA for OSD can ease the DSP and improve the facility and capability of the system.
