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.
