Two-Layer Video Coding Using Pyramid Structure for ATM Networks

ATM 망에서 피라미드 구조를 이용한 2계층 영상부호화

In transmission of image sequences over ATM networks, the packet loss problem and channel sharing efficiency are important. As a possible solution two-layer video coding methods have been proposed. These methods transmit video information over the network with different levels of protection with respect to packets loss. In this paper, a two-layer coding method using pyramid structure is proposed and several realizations of two-layer video coding methods are presented and their performances are compared.
