  • Relay apparatus for broadcast waves
    Patent number: 9118382
    Abstract: The objective of the present invention is to provide a relay apparatus capable of performing normal relay transmission for broadcast waves by preventing effects caused by wraparound in a relay apparatus. For broadcast waves received by a relay apparatus (2), the same broadcast data are placed in each of a defined segment (f0) and a first segment (f1) other than the defined segment, whereupon the relay apparatus removes broadcast data for the defined segment (f0) from the received broadcast waves, and transmits broadcast waves in which the broadcast data for the first segment (f1) have been exchanged with each of the defined segment (f0) and a second segment (f2) other than the defined segment and the first segment. As a result, the defined segment (f0) which imparts wraparound effects to the received broadcast waves is removed, and therefore, it is possible to perform normal relay transmission of the broadcast waves.
