Abstract

See full text

A dual communication mode system combines a point to point communications device with a television receiver and a video tape recorder. The result is a highly versatile and easily operated personal entertainment and communication center. The point to point communication device included in the personal communication and entertainment center can provide information to: (a) reset the center's time clock automatically if power to the center is interrupted or if the center clock must be synchronized to an accurate time; (b) program the personal entertainment and communication center from a remote location; (c) provide authorization signals to allow the personal entertainment and communication center to descramble coded signals received by the television receiver from a source such as a satellite or cable hookup; and (d) provide personal messages which can be recorded on the video tape recorder and displayed on the television screen.
