Abstract
Disclosed are a method, apparatus, system, and computer readable media containing instructions for preparing and displaying a plurality of audio-visual signals in a digital video distribution system (e.g., IPTV), which enables fast channel switching between channels. The system includes a server which sends a plurality of audio-visual signals coded in a base layer and enhancement layer format to an endpoint. The endpoint receives and decodes the base layer of a first channel, at least one second base layer of a second channel, and at least one enhancement layer of the first channel, and displays them on a video display.
