Abstract: According to one embodiment, a display apparatus includes a display, a receiver, and a tuner. The receiver is configured to receive position information indicative of a position where the display apparatus exists. The tuner is configured to tune a signal used for displaying an image on the display based on the position information.

Abstract: According to one embodiment, a viewer image processing module detects facial image data on a viewer from a shot image signal obtained by shooting the viewer, a viewed program image processing module detects facial image data on a performer included in program data the viewer is viewing, and a synchronous control module creates viewer information that correlates facial image data on the performer, facial image data on the viewer, and program information on the program with one another and transmits the viewer information to a viewing data entry module.

Abstract: According to one embodiment, a reference macroblock determination module determines, with respect to each of the peripheral macroblocks corresponding to the to-be-encoded macroblock, whether the macroblock is an encoded macroblock or not, determines, if the macroblock is the encoded macroblock, the macroblock as a reference macroblock which is to be used in order to determine a prediction mode candidate of the to-be-encoded macroblock, and to determine, if the macroblock is a non-encoded macroblock, an encoded macroblock, which is present in an encoded picture immediately preceding the to-be-encoded picture and which is present at the same spatial position as the macroblock, as the reference macroblock. A reference macroblock with a lowest cost is selected from these reference macroblocks, and the same prediction mode as the prediction mode of the selected reference macroblock is determined as a prediction mode candidate.
