Video Compression Demystified

Video compression is how enormous image data files get shrunk for fast transmission without significant loss of visual quality. It's the magic behind digital TV, videoconferencing, DVDs, and Internet video.Now is the time to learn about video compression--how to do it and how to use it. Peter Symes, a video compression specialist, paints the full video compression picture in this friendly, not-too-big, not-too-technical introduction. This is not a detailed implementation book, but it does explain what happens in compression, why compression works, and what will stop it from working.
