Abstract
Abstract A telecommunication system has a facility and an addressable terminal coupled through a transmission medium. The facility includes means 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 provided for non-addressed signals containing information corresponding to at least two channels of continuous audio. A selection code is inserted in one or more of the frames. The addressed video and audio frames and non-addressed signals are coupled to the transmission medium to the addressable terminal. The terminal has means for detecting said addressed video frames, addressed audio frames, and non-addressed signals. Circuits select video frames and audio frames in response to their corresponding addresses. One of said continuous audio channels is selected in response to said selection code.
