Abstract
A transmission system for packaging and transmission digital video data divides the data into a first group of components which would cause image quality to be drastically damaged if discarded, and a second group of components which would cause little damage if discarded. Data cells are composed for each group of components, and a priorty level is assigned giving a high priority to the first group of components and a low priority to the second group of components. The data is sent and received, and the received data is classified in accordance with the priority levels. If it is necessary to discard low priority components, a compensating device compensates for the discarded cells to ensure a constant image transmission across a congested channel.
