Abstract
The DCT-based image and video coding methods are tailored to fit into the ATM environment. Coding, packetization and reconstruction methods are designed jointly to achieve a good compromise among compression gain, system complexity, processing delay, error concealment capability, and reconstruction quality. The JPEG and MPEG algorithms for image and video compression are modified to incorporate even-odd block interleaving in the spatial domain and DCT coefficient segmentation in the frequency domain to conceal the errors due to packet loss. When combined with proper layered transmission, the proposed system can handle very high packet loss rates, at only slight cost of compression gain, system complexity and processing delay.
