摘要： A data communications system utilizes computer control at central and remote locations to provide general data acquisition and control functions as part of a cable television network. The data system includes a central data processor communicating with a plurality of remote data processors, each of which in turn interrogates, monitors and controls a plurality of groups of remote terminal unit. Each terminal unit includes a variety of security monitoring devices as well as other data generating apparatus useful in process control and data retrieval functions. Each terminal unit communicates with its remote data processor concerning the status of the security devices and receives commands from the remote data processor to carry out data acquisition and control functions including controlling access to the cable television network by the terminals. The remote data processors communicate with the terminal units utilizing both time and frequency division multiplexing in a frequency shift key mode. Communication between the remote data processor and the home terminals is preferably on the coaxial cable utilized for transmitting commercial programming for the television network. The central data processor includes a minicomputer interfacing with input/output devices and external data links. Each remote data processor includes a microcomputer having input/output devices attached thereto and interfacing between the minicomputer and the remote terminal units.

摘要： An addressable cable television control system controls television program and data signal transmission from a central station to a plurality of user stations. The data signals include both control and text signals in video line format which are inserted on the vertical interval of the television signals, thereby freeing all channels for transmission of both television and data signals. Moreover, full-channel teletext data in video line format may be transmitted on dedicated text channels with the modification of only head end processors. An intelligent converter at each remote user location uses the data signals to control access to the system on the basis of channel, tier of service, special event and program subject matter. The converter uses a graphics display generator to generate display signals for the presentation of the text data on the television receiver and for the generation of predetermined messages for the viewer concerning access, emergencies and other functions. The converter processes vertical interval text data and selected full-channel text data, both transmitted in video line format. The keyboard of the subscriber provides a number of different functional inputs for the subscriber to interface with the system. The converter also includes apparatus for interfacing with two-way interactive data acquisition and control systems.
