  • Patent number: 8830404
    Abstract: A broadcast receiving apparatus is equipped with a plurality of tuners that can respectively receive a control signal including region information identifying a region and channel designation information designating a program broadcast channel. A channel selection action of each tuner, display processing for a display unit, and recording processing for a storage unit are controlled based on a channel selection state of each tuner and the control signal. Furthermore, a tuner to select a channel designated by the channel designation information is determined based on a state of use of each tuner.

  • Patent number: 8670026
    Abstract: The video display apparatus is provided that the breaking up of the video image should not be viewed by users when the frame rate of video content items is changed in association with the change in the number of viewed content items. The video display apparatus, which is capable of viewing a plurality of video content items using the shutter eyeglasses, controls the plurality of video content items by time-division, and performs the shutter control of the shutter eyeglasses in association with the display videos. When the number of video content items which are to be viewed is changed, the control section controls the shutters of all of the shutter eyeglasses so that they close for the frame period of the video content items that are first output after a change of the frame rate.

  • Patent number: 7924817
    Abstract: The tuner unit of a digital broadcast receiving apparatus receives a digital broadcast and generates a data stream from a digital broadcast signal having a desired modulation frequency. A data stream of a digital broadcast is also input from an external digital broadcast receiving apparatus via an external I/F. A stream switching unit and demultiplexer play back the content on a desired channel, contained in the two data streams, on an image display unit in real time, and at the same time, store the content on the other channel, contained in the other data stream, in a storage unit. This makes it possible to watch one of at least two programs with different modulation frequencies while recording the other program.

  • Patent number: 6487614
    Abstract: Signals are transmitted through a plurality of transmission channels, each including at least a pair of signal lines for transmitting an interface signal, between a transmitter and a receiver. A predetermined signal is modulated by a modulator with a high-frequency signal, and the modulated signal is provided to a signal line of one of the plurality of transmission channels. A demodulator receives the modulated signal transmitted via this signal line, and demodulates the modulated signal from the signal line based on the frequency of the high-frequency signal. According to the above-described configuration, an interface control method and apparatus which can newly exchange other data and control signals while conforming to existent interface specifications are provided.
