This paper proposes a novel division transmission method for using multiple carriers to send a high-speed MPEG-2 TS signal that cannot be sent by conventional methods within one cable TV channel (6MHz band-width) transmission capacity. To meet the above requirement, we developed a flexible absorption technique of time lag between divided TS signals, and devised a new descriptor for the MPEG-2 TS. We made an experimental transmitter and a receiver, and evaluated transmission performance of these devices. Our tests show that the receiver can absorb the time lag between divided signals up to 1.36ms, and this corresponds to a difference of more than 272km in the transmission distance. Furthermore, experiments with prototype devices proved that the new descriptor enables the receiver to re-compose the original high-speed MPEG-2 TS automatically.
