Abstract: An image decoding method includes decoding encoded image data to generate a decoded image signal including a luma signal and a chroma signal. The method further includes scaling, when a reference field has a different parity from a current field for motion compensation and when the decoded image signal is in a format in which the number of chroma pixels is vertically different from the number of luma pixels, a chroma motion vector of the chroma signal according to an accuracy for a luma motion vector of the luma signal so that a reference frame will coincide in phase of the chroma signal with a current frame. The method also includes performing motion compensation of the decoded image signal using the scaled chroma motion vector according to the accuracy of the luma motion vector of the luma signal.

Abstract: A method and apparatus is disclosed for digitally compressing video signals. The method and apparatus provides a system which generates values related to the differences between respective pixel locations and an x,y pixel display. The differences generated between proximate pixel locations are used to generate various delta values which are encoded in an asymmetric fashion. The asymmetric coding eliminates artifacts in the displayed image, and the delta encoding is performed in both a horizontal and vertical direction (otherwise known as Two-Dimensional Delta Encoding) and this operation tends to randomly distribute error in the compression process across the visual image so as to approximate noise or grain generally perceived by the viewer in an analog display.

Abstract: A wide-aspect-ratio HDTV signal having 1600 luminance pixels/32 .mu.S line and 980 lines/frame is data reduced by deleting odd pixels of each line of TV field #1 and even pixels of each line of TV field #2 to produce 800 pixels per line, and is further data compressed by a form of differential-pulse-code modulation. The DPCM organizes the pixels into groups of five, and for each group transmits or records one reference pixel at full N-bits. The pixels to the right and left of the reference pixel are compared therewith to produce difference signals of M bits, where M

Abstract: A dual mode encoding/decoding technique for use in digital systems wherein transmitted digital words are limited, on average, to an alotted number of bits. The transmitted digital words are coded into first and second modes. The first coding mode utilizes predictive differential coding to provide a precision which can be greater than that obtainable by coding information solely with the allotted number of bits, while the second mode assures at least a minimum precision for the allotted number of bits. The first coding mode is transmitted as long as a preselected precision is provided. If not, the second coding mode is transmitted. In the disclosed embodiment, the dual mode encoding/decoding technique is applied to the transmission of color video signals.
