BROADCASTING RE-TRANSMISSION DEVICE AND BROADCASTING RE-TRANSMISSION METHOD

摘要

To construct an excellent system that re-transmits advanced wide band digital satellite broadcasting to a subscriber's house via a network such as a cable TV network.SOLUTION: A broadcast re-transmission device used for advanced wide band digital satellite broadcasting comprises: a tuner that demodulates a received satellite broadcasting wave including information on a program and TMCC information, outputs demodulation data including the information on the program, and can read part of the TMCC information not included in the demodulation data from a storage unit; a reading unit for reading first information, part of the TMCC information, from the storage unit of the tuner; an information creation unit for creating second information, information included in the TMCC information and differing from the first information; an information recovery unit for integrating the first information with the second information to recover part or all of the TMCC information; and a stream generation unit for generating a stream including the demodulation data and the TMCC information.SELECTED DRAWING: Figure 4
