Realization of automatic video data acquisition based on SONY cassette recorder 基于SONY录像机的视频数据自动采集实现
This system contains all necessary control and data circuitry to interface with CRT, standard ASCII keyboard, matrix line printer, EPROM programmer, dual single side double density floppy disk drive, cassette tape recorder, etc. 系统具有各种必要的控制及数据线路,可以与CRT、标准键盘、针型行打、EPROM编程器、单面双密度软盘驱动器、盒式磁带录音机等相接。
Existing buffer strategies are mainly based on sliding window and data prefetch. However, the media on demand streaming hardly utilizes the buffer data when users perform VCR ( Video Cassette Recorder) operations frequently. 目前的对等节点缓存策略一般采用滑动窗口和预取数据的方式,但对于用户VCR(VideoCassetteRecorder)操作频繁的流媒体点播,不能有效地利用节点的缓存数据。
