  • Patent number: 8345171
    Abstract: Methods, systems, and apparatus, including computer program products, for changing digital broadcast channels. In one implementation, upon receiving a request for switching to a new channel in a digital broadcast receiving device, the device switches from a power saving mode, in which the device processes time-slices only for the currently selected broadcast channel, to a channel changing mode, in which broadcast data is buffered for more than one broadcast channels in anticipation of channel surfing. In another implementation, the user's perception of the channel change delay is mitigated by displaying channel information about the newly selected channel.

  • Patent number: 8319899
    Abstract: A front-end circuit according to the present invention includes a VCO which oscillates a local signal, a mixer which converts an RF signal Frf into a baseband signal, a DC offset cancel circuit which detects a DC offset contained in the baseband signal and then eliminates the DC offset, and a local frequency control circuit which controls a frequency of the local signal. In a case where the RF signal is an analog television signal, the local frequency control circuit controls the frequency of the local signal so that a frequency of the baseband signal differs from each frequency spectrum of a luminance signal contained in a video signal which is generated by demodulating the baseband signal. This makes it possible to provide the front-end circuit which can prevent video distortion caused when a frequency spectrum is eliminated from the luminance signal.

  • Patent number: 8314894
    Abstract: In the usage of table projection of a projection type display, depending upon a sitting position of a participant of a conference, the participant views an image projected upon a table as an inversion image turned upside down, resulting in poor visual recognition. In order to improve visual recognition, images are rotated, synthesized and displayed in accordance with the viewing direction of each participant. More specifically, the projection type display is provided with a two-image synthesizing unit for synthesizing two images obtained by processing an input image by two image rotation units for rotating the input image by a first angle and a second angle different from the first angle, into one image on a screen. The projection type display is also provided with an image rotation unit and an image inversion unit for two-image display on a screen.

  • Patent number: 8310598
    Abstract: An apparatus for splitting a signal and a video device using the same are disclosed. The apparatus includes a first splitting unit to split an inputted broadcast signal into a first broadcast signal and a second broadcast signal, and to supply the first broadcast signal to a first broadcast signal processing element, and a second splitting unit to split the second broadcast signal into a third broadcast signal and a fourth broadcast signal, and to supply the third broadcast signal to a second broadcast signal processing element. With this construction, the apparatus can distribute and provide a broadcast signal with a noise figure (NF) lower than that of other broadcast signals, to an element, which requires a broadcast signal with a low noise figure. In addition, the apparatus can split the inputted broadcast signal without using an active element, such as an amplifier or the like, thereby allowing the split broadcast signals to lower the NF thereof and to uniformly maintain a gain thereof.

  • Patent number: 8305490
    Abstract: A de-interlacing system includes a motion adaptive de-interlacer, a horizontal motion estimation device, a horizontal motion compensation device, a vertical motion detection device, a multiplexer, and a film signal detector. The film signal detector receives an input signal and decides whether the input signal is a video stream or a film stream to thereby select an output from the motion adaptive de-interlacer or the horizontal motion estimation and compensation device. Thus, a de-interlacing output has stable and smooth edges when a video stream is inputted, and the motion judder phenomenon is reduced when a film stream is inputted.
