Title: Motion vector quantizing selection system
Inventor: ISRAELSEN PAUL D
IPC: H04N7/26
Filed: 1996-11-08
Granted: 2003-09-16
Abstract: A video telephone system includes a camera (14) that produces video images. Processing circuitry (88, 100) performs vector quantization on the video images to represent the video images with a relatively small amount of data for transmission to a remote location or memory (fig. 7). The video images a re represented by frames which may be further divided into blocks (54). A curre nt block is the block that is being considered at a given time. A conditional previous block occupies the position in a previous frame that the current block occupies in the current frame. A motion previous block is a block of t he previous frame (42A) containing data like that of the current block. To further reduce the amount of data needed to represent the video images, the processing circuitry (88, 100) determines what, if any, quantization is need ed with respect to the current block. The processing circuitry (88, 100) may perform either vector quantization on the current block, or vector quantization on a residual (68) between the current block and motion previou s block, or pass bits indicating that the vector quantization of the condition al previous block is adequate. The decision (96) which occurs depends on variou s distances related to the current block, the motion previous block, and the conditional previousblock. The invention has application for images other than those used in video telephone systems.

Title: Protection of a component video signal
Inventor: RYAN JOHN O
IPC: H04N5/92
Filed: 1998-06-16
Granted: 2002-11-26
Abstract: A VGA (or other component video signal) output, e.g. from a computer or DVD  player, is protected so it is viewable on a VGA monitor. However, if the component video signal is converted to composite video (e.g. television) the resulting television picture is of substantially degraded quality, thereby inhibiting viewing and/or copying. This protects for instance copyrighted material in the VGA format from unauthorized use. The protection involves modifying the horizontal or vertical synchronization signals in the VGA video in such a way that there is no adverse affect on a typical VGA monitor.  However, most or all VGA to television converters and/or television sets and VCR's suffer from loss of synchronization, resulting in an unviewable picture.  Also, methods and circuits for defeating the copy protection are provided.
