Abstract
This chapter focuses on discussion of the video coding basics and the most widely used MPEG-2 and H.264 video coding standards, along with the present requirement of scalable video coding. Video coding enables the digital storage and transmission of video signals. Digital technology has made the widespread use of compressed digital video signals practical. At the source end, the video encoder compresses the digital video for efficient storage and transmission purposes, whereas the video decoder at the destination end decompresses the received compressed video stream and sends to the display for viewing. In addition, scalable video coding (SVC) is a highly attractive solution to problems posed by characteristics of modern video transmission systems. The SVC can be used for various application scenarios such as bandwidth adaptation, content adaptation, and complexity adaptation. The SVC scheme supports an arbitrary number of temporal/spatial/SNR scalability layers and offers scalability at a bit stream level.
