Abstract: A television broadcast receiving apparatus can change an oscillation frequency of a local oscillation signal or a tuning frequency of an intermediate frequency signal in a reception channel, and changes the reception characteristic to an optimum reception characteristic. In this way, the television broadcast receiving apparatus effectively reduces SN ratio deterioration due to interference of the outside of a reception band such as adjacent channel interference.

Abstract: Systems, methods and devices are disclosed that provided for providing remote video feedback. The disclosure herein includes a transmitting computing device that is configured to produce an image frame encoded with metadata and to transmit the encoded image frame over a network to a remote display device. The remote display device includes a viewing screen contained in a chassis with bevel. The viewing screen includes an information validation pixel with the chassis extending over and covering the image validation pixel. The chassis also includes a photo sensor positioned on the under side of the bezel so as to be in operational view of the image validation pixel. The system also includes a sensor electronics module that is configured to detect the metadata when the metadata is displayed by the information content pixel and is received by the photo sensor.

Abstract: Provided is an image quality evaluation system for evaluating quality of an image. The image quality evaluation system includes bit extraction means and image quality evaluation means. For predetermined data expressing an image frame of a first image, the bit extraction means extracts a predetermined number of bits which is smaller than the number of bits required for expressing one data piece. By using a value expressed by the bit string extracted by the bit extraction means and a value of data equivalent to the data to be extracted from the bit string in a second image, the image quality evaluation means estimates a difference between the first image and the second image and evaluates the image quality of the first to image or the second image.

Abstract: Receivers using multiple tuners may introduce crosstalk between signals provided to the tuners. The disclosed embodiments relate to a method and apparatus for detecting and preventing crosstalk. A method is described that includes providing a signal to a first signal processing path, tuning to a channel in the signal provided through the first signal processing path, tuning to the channel in the signal through a second signal processing path, and determining that crosstalk exists if the channel is present on the second signal processing path. An apparatus is also described containing means for providing a signal to a first signal processing path, tuning to a channel in the signal provided through the first signal processing path, tuning to the channel in the signal through a second signal processing path, and determining that crosstalk exists if the channel is present on the second signal processing path.

Abstract: To provide a video display device capable of transmitting attribute information more securely to a video output device capable of bidirectional communication. In a case in which there has been a request from the video output device for EDID attribute information, monitoring is performed to determine whether or not transmission of the EDID is completed properly (S8, S9). In a case in which EDID transmission is not completed properly, a reset process is performed in which a connect detection line is returned to a connected state after it is temporarily put into a disconnected state (S13).

Abstract: A high frequency receiver cancels a plurality of noise signals which are contained in a high frequency signal and outputted from a plurality of noise signal sources. The high frequency receiver cancels the noise signals using a plurality of pick-up noise signals extracted from a plurality of pick-up antennas disposed near the noise signal sources. At least one of the pick-up noise signals is selected in descending order of their effects on the degradation of reception quality, thereby completing noise cancelling in a short time.
