Other Related Research Issues
The success of video database systems is not solely dependent on the digital video database techniques discussed in the last chapter, it also relies on many other issues. In this chapter, several important issues are described. Video compression, which is very important for video data storage and transmission, is first introduced. This is followed by the description of the video server system design and file system support, an issue that is critical to the real-time, quality of service guaranteed applications of the video database systems, e.g. video-on-demand systems. Transmission of video data across computer network is posing new challenges to networking technologies; some of the efforts along this line are discussed. Another challenging issue is the protection of the exclusive rights of the owner of the digital video data (as well as other digital media), while at the same time allowing legal digital media sharing. Both are crucial to the success and acceptance of digital media sharing systems, like a video database.
