An interactive system transfers video and audio information from a central facility to terminals by means of addressed television frames. Each audio frame includes information representing a single channel of time compressed audio. The terminals store correctly addressed frames. Video frames are repeatedly replayed to provide series of still-frame images. The audio frame is used to generate a normal speed audio output.

Telecommunication system with video and audio frames

A telecommunication system for transmitting video and plural audio information on a transmission medium includes a facility and an addressable terminal. The facility includes arrangements for providing addressed video frames containing information corresponding to still images and for providing addressed audio frames containing information corresponding to audio bursts. There is also means for providing non-addressed signals containing information corresponding to at least one channel of continuous audio. The addressed video frames, addressed audio frames, and non-addressed signals are coupled to the transmission medium and sent to the terminal. The addressable terminal includes means for detecting said addressed video frames, addressed audio frames, and non-addressed signals on said transmission medium. Circuits select video frames and audio frames in response to their corresponding addresses. Arrangements are made for storing still images contained by selected video frames and for storing and playing audio bursts contained by selected audio frames. Circuits provide continuous audio signals contained by said non-addressed signals. A circuit attenuates the continuous audio signals in response to playing of an audio burst.
