    Abstract: All macro blocks (MB) decided as an “all_0”, “all_255” or “intra predicted” mode are transmitted as an “intra not coded” mode. A receiving terminal also separates “all_0”, “all_255” and “intra predicted” from the “intra not coded” mode, referring to pixels of a lower layer. “Inter coded && MVD=0” and “Inter coded && MVD!=0” modes are represented as “Inter coded”, and “Inter not coded && MVD=0” and “Inter not coded && MVD!=0” modes are represented as “Inter not coded”. As its result, coding modes on an I-picture can be reduced to two modes and coding modes on a P-picture, or a B-picture, can be lessened to four modes.

    Abstract: An apparatus and method for image-compression encoding and decoding using an adaptive transform in which, where different transform coefficients are outputted in accordance with a change of the transform direction order for an input image signal block, encoding and decoding procedures are conducted, based on the transform direction order selected in accordance with the characteristics of the input image signal block. In accordance with the present invention, an orthogonal transform and a inverse orthogonal transform for blocks are controlled, based on a determination made about whether signals within a block, to be currently encoded, have a higher correlation in a vertical direction or in a horizontal direction, using information about blocks encoded or both information about blocks encoded and information about the current block. In accordance with the present invention, the orthogonal transform is conducted in a direction associated with a higher correlation and then in a direction associated with a lower correlation. The inverse orthogonal transform is conducted in the order inverse to that of the orthogonal transform. Accordingly, the present invention provides an enhancement in compression coding efficiency.

    Abstract: A method for coding a digital moving video including gray scale shape information. Picture-unit overhead information is first transmitted and it is then determined whether a video packet to be coded is a first packet of a given picture. A video packet header including overhead information for the decoding of the gray scale shape information is transmitted if the video packet is not the first packet of the given picture. Then, it is determined whether the given picture is an intra picture. If the given picture is the intra picture, the video packet is coded and transmitted in an intra picture mode. If the given picture is not the intra picture, the video packet is coded and transmitted in an inter picture mode. If the video packet is not a last packet of the given picture, a digital moving video coding operation is performed repeatedly. The digital moving video coding operation is ended if the video packet is the last packet of the given picture. Even when the coded video packet is transmitted through a channel where a transmission error may often occur, such as a mobile communication channel, a decoder can perform an error concealment operation of high performance to reconstruct a moving picture of high quality.

    Abstract: A plurality of layers having other resolution are coded in order to encode scalably shape information. A base layer having the lower resolution is coded and transmitted to a decoder, and an enhancement layer is coded by employing a scan interleaving method from the base layer. A scan order of vertical and horizontal scannings is decided according to a generation frequency of TSD (transitional sample data) and ESD (exceptional sample data) and the number of coding bits on the base layer, or a type of boundary lines on images. When the scan order is decided, additional information indicating the scan order is transmitted to the decoder. The base layer is also coded and transmitted to the decoder. In case that the scan order is decided according to the horizontal and vertical of the boundary lines on an image of the base layer, it is no need to transmit the additional information indicating the scan order on the received base layer and execute the decoding in the same order as the coded scan order.
