Abstract
The present invention provides tuner and receiver apparatus that can output first transport stream data and second transport stream data having excellent bit error rate characteristics for two systems even when a first tuner portion and a second tuner portion are provided on one board. According to the present invention, a first tuner portion is provided on one surface of a board, and a second tuner portion is provided on the other hand of the board.
Claims9
A tuner apparatus comprising a first tuner portion for receiving a first broadcast wave and outputting first transport stream data achieved by multiplexing encoded data on sounds and/or pictures contained in the first broadcast wave, and a second tuner portion for receiving a second broadcast wave different from the first broadcast wave and outputting second transport stream data achieved by multiplexing encoded data on sounds and/or pictures contained in the second broadcast wave, said first and second tuner portions being provided on a board, wherein said first tuner portion is provided on one surface of said board and said second tuner portion is provided on the other surface of said board.
A receiver apparatus comprising:
- a tuner apparatus in which a first tuner portion for receiving a first broadcast wave and outputting first transport stream data achieved by multiplexing encoded data on sounds and/or pictures contained in the first broadcast wave is provided on one surface of a board, and a second tuner portion for receiving a second broadcast wave different from the first broadcast wave and outputting second transport stream data achieved by multiplexing encoded data on sounds and/or pictures contained in the second broadcast wave is provided on the other surface of said board;
- decoding means for decoding the first transport stream data and said second transport stream data;
- and
- an output terminal for supplying the first and second transport stream data thus decoded to a display device for outputting the sounds and/or the pictures.
