Embodiment Construction

[0024] Hereinafter, embodiments of the present technology will be described with reference to the drawings.

[0025] [overall overview configuration]

[0026] figure 1 is a block diagram showing an example of the functional configuration of the tuner of this embodiment. Note that the tuner of this embodiment can have various modes. For example, a tuner may be a module or part of a receiver device.

[0027] For example, the tuner of this embodiment is each of various devices (television, video recorder, set-top box, etc.) capable of receiving terrestrial television broadcasting and satellite television broadcasting and capable of reproducing broadcast signals. Of course, the tuner of this embodiment may not necessarily receive television broadcasts. The tuner of this embodiment may be any device configured to receive signals from both systems and to selectively function as one of a low-pass filter and a band-pass filter as desired.

Abstract

Provided is a receiver apparatus, including: a first receiver configured to receive a first signal having a first frequency band; and a second receiver configured to receive a second signal having a second frequency band, the second frequency band being different from the first frequency band, in which a signal path for the first signal and a signal path for the second signal share at least one component in a signal path for extracting an intermediate-frequency signal from a received signal, the component being configured to extract a signal of a particular channel from the received signal as the intermediate-frequency signal.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Japanese Priority Patent Application JP2014-041423 filed Mar. 4, 2014, the entire contents of which are hereby incorporated by reference. technical field [0003] The technology relates to receiver devices, tuners and circuits. Background technique [0004] If one IC has a function of receiving broadcast (transmission) signals of different frequency bands (for example, terrestrial TV broadcasting and satellite TV broadcasting) as an independent receiving function, the layout area may increase in size. [0005] In view of the foregoing, according to the technology disclosed in Japanese Patent Application Laid-Open No. 2013-236196, a phase synchronization circuit and a voltage-controlled oscillator are used to receive both terrestrial and satellite television broadcasts. As a result, the layout area of ​​the IC shrinks in size. Contents of the invention [0006] According to the...
