This paper describes a variable rate moving image coding system for video distribution services using the asynchronous transfer mode (ATM). The system is based on band division, and permits high performance coding of moving images as well as control of maximum coding rate. It can also deal with cell loss and usage parameter control in ATM networks. In simulation where the system was evaluated using test pictures, it was found that the average coding rate was 20 - 30 Mbit/s, and that the coding rate could be controlled to suppress picture quality deterioration.
