High Quality Content by WIKIPEDIA articles! A video server is a computer based device dedicated to delivering video. Unlike personal computers, being multi-application devices, a video server is designed for one purpose; provisioning video, often for broadcasters. A professional grade video server records, stores, and plays back multiple streams of video without any degradation in the video signal. Broadcast quality video servers often store hundreds of hours of compressed audio and video (in different codecs), play out multiple and synchronised simultaneous streams of video, and offer quality interfaces such as SDI for digital video and XLR for balanced analog audio or AES/EBU digital audio and also Time Code. A genlock input is usually provided to provide a means of synchronizing with the house reference clock, thereby avoiding the need for timebase correction and frame synchronization. Video servers usually offer some type of control interface allowing them to be driven by more sophisticated scheduling or play-listing applications. Popular protocols include VDCP and 9-Pin Protocol.
