Abstract
Official abstract text for this publication.
In a receiving device, an oscillating section generates a local oscillating signal for performing frequency conversion of one reception target channel of channels in broadcasting in a first frequency band and channels in broadcasting in a second frequency band; a first receiving section generates a channel signal based on the local oscillating signal and a high-frequency signal in the first frequency band when the reception target channel is a channel in the first frequency band, and does not perform the generation when the reception target channel is a channel in the second frequency band; and second receiving section generates a channel signal based on the local oscillating signal and a high-frequency signal in the second frequency band when the reception target channel is a channel in the second frequency band, and does not perform the generation when the reception target channel is a channel in the first frequency band.
First claim
Opening claim text (preview).
What is claimed is: 1. A receiving device comprising: an oscillating section configured to generate a local oscillating signal for performing frequency conversion of one reception target channel of channels in broadcasting using a first frequency band and channels in broadcasting using a second frequency band different from the first frequency band; a first receiving section configured to perform generation of a channel signal for obtaining broadcasting output of the reception t…
