CATV NETWORKS AS BASIS FOR INTERACTIVE VIDEO SERVICES

摘要

The forthcoming introduction of interactive video services such as video-on-demand, which is facilitated by recent advances reached in source and channel coding as well as modulation, calls for a network platform via which the subscriber can access the appropriate sources of information. One such approach, the use of the broadband CATV network, will be detailed in this paper. In so doing, special emphasis needs to be placed on backward channels.
