Abstract
Asynchronous Transfer Mode (ATM) is expected to be one of the important variable-bit-rate methods for video transmission. Packet loss has the greatest influence on picture quality in video network. This paper proposes a layered coding technique suitable for ATM using discrete cosine transform (DCT) cod-ing. The proposed layered coding separates coded information into most significant parts (MSPs) and least significant parts (LSPs) and gives MSP packets priority over LSP packets to reduce the influence of packet loss on picture quality. The influence of packet loss on picture quality is also described, and the effectiveness of the proposed layered coding is confirmed with decoded pictures.
