  • Method and apparatus for recording and rendering programs that cross SDV force tune boundaries
    Patent number: 8141123
    Abstract: A method is provided for recording a switched digital video (SDV) program received over a content delivery system. The method includes receiving a single program digital transport stream on a first SDV channel. The single program digital transport stream includes at least one program elementary stream and associated program specific information. The program elementary stream and the associated program specific information are stored. In response to a force tune request, a second SDV channel is tuned to on which a subsequent portion of the single program digital transport stream will be provided. After tuning to the second SDV channel, subsequent portions of the program elementary stream are stored in a content file in which previous portions of the program elementary stream are stored.
