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.
