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.
