Scalable video codecs are provided for use in videoconferencing systems and applications hosted on heterogeneous endpoints/receivers and network environments. The scalable video codecs provide a coded representation of a source video signal at multiple temporal, quality, and spatial resolutions.

System and method for scalable and low-delay videoconferencing using scalable video coding

Techniques for transmission and preparation for display of real-time audio-visual content of a plurality of TV programs over electronic communications network channels and display of the audio-visual signals as a part of a TV Electronic Programming Guide (EPG) are disclosed herein. In particular, the use of video coded using a layered codec, and stored in a layered format, allows a properly configured system to present to an end user a live preview of multiple TV channels, along with EPG information (e.g., the channel, time, title and genre of video content, a list of programs scheduled in the future, as well as the ability to, for example, set parental controls, order pay-per-view programs, to search for programs based on theme or category, and to set recordings for the future when combined with a recording system), on his/her TV screen, without taking significantly more resources (e.g., in terms of bandwidth, system complexity) than the traditional digital TV transmission.

System and method for an active video electronic programming guide

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.
