Error Or Fault Detection During Recording Or Reproducing Operation For Video Signal Patents (Class 386/263)
  • Publication number: 20110129200
    Abstract: If a movie reproducing apparatus detects an error during reproduction of encoded movie data, based on management information that includes a recording position of an intra-picture coded picture included in the encoded movie data, the movie reproducing apparatus determines a position used when the error is recovered by searching for an intra-picture coded picture subsequent to a frame including data with the error as well as updates elapsed time information to be displayed based on a frame number of the searched intra-picture coded picture at the time the error is recovered.

  • Patent number: 7912352
    Abstract: When playing an AV Clip recorded on a BD-ROM, a judgment is made, for each elementary stream, which of a plurality of predetermined conditions the elementary stream satisfies. The plurality of predetermined conditions include (a) a condition that a playback apparatus has a capability of playing the elementary stream, (b) a language attribute of the elementary stream matches a language setting of the playback apparatus, and (c) a channel attribute of the elementary stream is surround sound and the playback apparatus has a surround output capability. The playback apparatus assigns a priority to each elementary stream based on which conditions the elementary stream satisfies, selects an elementary stream having a highest priority, and plays the selected elementary stream.

  • Patent number: 7895615
    Abstract: A system and method for applying quality assurance methods in the determination of whether or not to present previously recorded digital content as available to a viewer at a customer site. The present invention checks the digital content and makes a quality assurance comparison in determining whether to add content to an electronic program guide for selection by a customer. The present invention presents acceptable recorded content as available, and withholds unacceptable content as a means of quality assurance.

  • Patent number: 7881588
    Abstract: A reproducing apparatus includes: a reproducing unit for reproducing, from a recording medium on which main image for normal reproduction data and specific reproduction image data made up of a plurality of blocks each including first data and second data are recorded, the main image data and the specific reproduction image data; a detecting unit for detecting an error in the first data and an error in the second data in the respective blocks of the specific reproduction image data that is reproduced by the reproducing unit, independently; and an interpolation processing unit for interpolating independently the first data and the second data in which the error is detected by the detecting unit, by selectively using a plurality of interpolating methods.

  • Publication number: 20110013889
    Abstract: A video bit stream with pictures comprising inter-coded content can be decoded upon receiving a channel start or file seek instruction. Pictures for beginning decoding and display of the bit stream can be selected based at least in part on one or more tuning parameters that set a preference between a latency of beginning to display video and possible defects in the displayed video. In some embodiments, to implement decoding upon a channel start or file seek, one or more types of data are generated for one or more pictures. For example, picture order counts are generated for pictures after a channel start or file seek operation. As another example, a decoder generates a frame number value that triggers re-initialization of a reference picture buffer before decoding after a channel start or file seek operation.

  • Publication number: 20110008018
    Abstract: Footage used in an aired show by a broadcaster, broadcasting network or similar entity can be more easily tracked and reported to rights holders. An electronic cutsheet can be created for a video package. The electronic cutsheet includes information identifying one or more footage items included in the video package and any rights holders associated with the footage item. Using the cutsheets, a number of playlists can be created or otherwise provided. Each playlist is associated with at least one video package. The playlist can then be associated with a show to indicate that the show has aired and thus that the playlist and its included packages have actually been used. A report can then be generated that indicates at least one rights holder and the number of instances in which a footage item associated with the indicated rights holder was included in an aired show.
