Abstract
The Broadband Integrated Services Digital Network (BISDN) based on lightwave technology is supposed to become the all-purpose exchange area communications network of the future. All digital video services are integrated with applications ranging from videophone, teleconferencing to digital TV (signals according to the CCIR rec. 601) and High Definition TV (HDTV) distribution. A desirable feature of the various video services is the upward and downward compatibility in resolution in order to guarantee a free exchange of services, transmitters and receivers. This paper proposes an n-level progressive hierachical intraframe coding scheme based on subband coding. In this scheme several spatial low-resolution services are available as subsets of the coded HDTV data which can directly be received at lower bit rates. Progressive coding of the HDTV signal is employed in order to prevent quantization errors from propagating to higher resolution signals. Special attention is given to the design of the quantizers required for the progressive coding, and to the incorporation of the side panels coding.
