Abstract
A cable television and communication system is disclosed which is suitable for community antenna television (CATV) closed circuit television (CCTV) and other types of signal distribution systems with service function applications such as for use in hotel, motel, apartment complexes, and the like. The system has the capability of distribution and subscriber reception of unencoded and encoded or limited access video and audio programs with simultaneous two way digital data communication. The subscriber units are interconnected by a tree-organized wideband communication link such as co-axial cable system with a network central unit. Subscriber unit identification control and data exchange is accomplished by the use of a high speed time-slot organized format with each subscriber being assigned a predetermined unique television synchronization related time-slot. The central unit utilizes a small digital computer which functions to provide network supervision and management of subscriber requests, accounting, billing and other processing such as viewing analysis. The system utilizes a modular configuration which allows for a low cost and simple initial installation capable of being later expanded to a more sophisticated version.
