ABSTRACT:
A method is provided for transmitting a plurality of informational video programs over a single digital transport stream to a plurality of receivers, wherein the receivers are operative to select from the transport stream data identified with any given program and to decode the identified data into a displayable video signal. The method consists of storing a plurality of the informational video programs, scheduling them along corresponding simultaneous time lines, rendering each program and encoding, according to standards, into a video stream, multiplexing the video streams in an interleaved manner, and formatting them to become the transport stream, wherein any of the operations of scheduling, rendering encoding and multiplexing are such that images, obtained by decoding transmitted data identified with any of the programs and displaying the resultant video signal, are essentially similar to those obtainable by rendering and encoding the programs separately, transmitting the respective encoded program alone over a similar transmission stream, decoding the transmitted data and displaying the resultant video signal.
