  • Patent number: 7945930
    Abstract: A method for controlling a recording function of a video apparatus improves recording quality by preventing certain display functions of the apparatus from adversely affecting the resultant recording. A problem may arise in certain video signal processing apparatuses when the user selects a recording function after selecting a particular user-activated display function because the user-activated display function may result in the recording of the video signal in an undesired format, for example a different aspect ratio, or zoom mode. According to an exemplary embodiment, the present invention overcomes this problem by providing a method that includes the steps of detecting activation of a recording function of a video apparatus, and turning off a user-activated display function of the video apparatus responsive to the detection.

  • Publication number: 20110102680
    Abstract: A request recognition section (373) recognizes an input operation for a source switching request to switch broadcast program contents extracted from broadcast waves to contents recorded in a recording and reproducing apparatus to display the contents on a display unit (350). Values of a plurality of setting factors such as brightness, contrast, and black level related to picture quality, which correspond to the source to be switched, specified corresponding to the previous contents source are read from a memory (360). Predefined values of the setting factors set corresponding to the previous contents source are compared with values newly read, and the values of the respective setting factors are sequentially changed stepwise. It is possible to prevent a flicker on a screen caused by a sudden change in the picture quality during processing of changing the picture quality, thereby favorably adjusting the picture quality.

  • Patent number: 7936402
    Abstract: Provided is a method for setting a digital broadcasting channel in a digital broadcasting receiver having a tuner and a demodulator. According to the method, when an automatic channel setting command is input by a user, a channel is selected using a tuner, and whether an NS flag is detected in each channel is judged. When the NS flag is not detected as a result of the judgment, a mode of each selected channel of the digital broadcasting receiver where signals are detected is judged from a VSB mode and a QAM mode. A channel map is constructed according to the judgment result. Accordingly, the method allows a subscriber or a manufacturer to automatically detect signals and store a corresponding channel in a channel map without separately setting cable broadcasting in cable digital TV broadcasting environment where VSB and QAM modes are provided.

  • Patent number: 7936827
    Abstract: An information processing apparatus includes a receiving device and a control unit. The receiving device includes a plurality of processing unit containing an interface unit. The control unit includes an input source detection module, a transfer instruction detection module and a power-saving control module. The input source detection module detects an input source necessary for execution of a video reproduction program. The transfer instruction detection module detects a video data transfer instruction from the video reproduction program. When the video data transfer instruction is detected, the power-saving control module enables some of the processing units except the interface unit and sets the others of the processing units in power-saving mode. The enabled processing units receive a video signal from the input source detected by the input source detection module and convert the video signal into video data of given format.
