Patent ID: 8767131

Claim:
A semiconductor device comprising: a first tuner I/F that is connected to a first tuner for tuning in a first broadcast wave, the first broadcast wave transferring content data; a second tuner I/F that is connected to a second tuner for tuning in a second broadcast wave, the second broadcast wave transferring the content data; a decoder that selectively decodes a first broadcast signal supplied from the first tuner I/F and a second broadcast signal supplied from the second tuner I/F; a general purpose processor that is provided separately from the decoder and decodes the first broadcast signal; and a switch unit that, based on signal intensity of the second broadcast wave, switches the decoding by the decoder between the first broadcast signal and the second broadcast signal while the general purpose processor is decoding the first broadcast signal, wherein the first tuner I/F, the second tuner I/F, the decoder, the general purpose processor, and the switch unit are integrated on one chip.
