Abstract: Techniques for delivery and presentation/display of audio-visual signals over electronic communications network channels are disclosed herein. In an exemplary embodiment, a video server for an IPTV system is disclosed. The system includes a video extractor/transporter (shortly referred to as video extractor) for extracting encoded audio-visual signals from at least one video source, and distributing the signals over the electronic communications network channels. The system also includes control logic which can receive control messages from receivers and invoke the video extractor to extract audio-visual signals therefrom.

Abstract: 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.

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.

Abstract: Disclosed are techniques for a system and protocol that provides for composition of a video scene that embeds one or more video sequences into a background image. The protocol enables a video stream presentation system (e.g., IPTV) to automate the embedding by one or more decoders of video sequence content and non-background information, for example, stock tickers, close caption, or date/time information, into a background.

Abstract: Disclosed are a system, method, apparatus, and computer readable media containing instructions for displaying video files for rapid searching. In two different types of exemplary embodiments, a standalone video skimming system, and a video skimming system includes a server and a client system are disclosed, where the video file may be locally or remotely stored, or can be obtained from a live feed. The system displays many small windows simultaneously, in which different parts of the video chosen by the user are shown at the same time to shorten the skimming time. The video file is encoded using layered encoding to display smaller versions using lower layers, and without needing any processing to generate smaller versions of the video from the original full screen version.
