Abstract: Methods, systems, and computer readable media can be operable to facilitate the detection and management of a filler region during trickplay of a content stream. A filler region at the edge of a targeted advertisement segment may be detected based on the presence of one or more consecutive I-frames. When a filler region is detected during a trickplay operation, a corrective method may be applied during trickplay of the filler region. The corrective method may include a modification of a frame skip count (FSC) and/or frame repeat count (FRC) during trickplay of the filler region, or may include skipping over the processing and output of filler frames during trickplay of the filler region. In embodiments, an index file may be modified to include an indication of a designation of one or more frames as either a filler frame or non-filler frame.

Abstract: Methods, systems, and computer readable media can be operable to facilitate the anticipatory acquisition of PMT information. A device may recognize a trigger within a transport stream, wherein the trigger indicates an audio/video transition and initiates a PMT acquisition by the device. Upon acquisition of the PMT, the device may process information carried by the transport stream after the audio/video transition. In embodiments, a device may acquire a PMT having information associated with a planned audio/video transition, wherein the information includes a time reference for when the audio/video transition will occur and information that may be used by the device to process information carried by the transport stream after the audio/video transition.

Abstract: An audio/video content management apparatus, for use with an external hard drive, includes a control circuit that performs a trust token generation operation. The trust token generation operation includes obtaining first identification information and hard drive identification information, encrypting and combining the first identification information and the hard drive identification information as a trust token, and sending the trust token to the external hard drive. The control circuit also performs a trust token validation operation including obtaining the first identification information, the hard drive identification information, and the trust token from the external hard drive.

Abstract: Methods, systems, and computer readable media can be operable to facilitate a unique protection of recorded content. A central device may be configured to establish and maintain associations between unique passwords and one or more individual recordings. A user may provide a unique password to be associated with one or more individual recordings. When a recording is associated with a unique password, the central device may require entry of the unique password before carrying out an action such as playback or deletion of the recording.

Abstract: A system is provided for providing a trickplay operation using a digital video recorder (DVR) when the video includes Broadcom Transport Packets (BTPs) designed for MPEG-2, but in an MPEG-4 video steam. In a first embodiment, to enable trickplay to function properly with MPEG-4 video, the BTP descriptors included with each group of data frames are disabled so that a single descriptor provided without BTPs that would otherwise be provided in MPEG-4 is all that remains. In a second embodiment, the 5 descriptors for MPEG-4 are combined into a single descriptor. In a third embodiment, the pace of decoding of the MPEG-4 descriptors is increased so that the speed of encoding all the 5 descriptors is comparable to the pace of decoding a single MPEG-2 descriptor.
