International Classification:

H04N007/16
H04N007/173

US Classification:

725/088000, 725/102000, 725/090000, 725/028000

Abstract:

A personal video recorder records and plays back a television program in a user-defined playback mode while preserving content advisory rating information. A decoder parses a digital transport stream comprising transport stream packets containing the television program and generates navigation data. A source of content advisory rating information corresponding to said television program is provided. This source of content advisory rating information may be within the digital transport stream. A non-volatile storage unit is used for saving each of the frames of the television program in a transport stream file and for saving the navigation data in a navigation data file. The navigation data includes pointers that point to a location of each of the frames of the television program in the transport stream file and content advisory rating information associated with each of the frames from the source of content advisory rating information. A processor for executes an algorithm that processes the transport stream file according to the user-defined playback mode. Content advisory rating information that corresponds to frames that are to be shown in the user-defined playback mode is taken from the navigation data file and inserted in the video output signal.

International Classification:

G09G005/00

US Classification:

345/720000

Abstract:

A display device with personal versatile recorder capabilities is provided which is capable of processing progressive I-slice refreshed MPEG data streams to enable trick play mode features. The display device comprises a receiver for receiving a progressive I-slice refreshed MPEG data stream having I-slices distributed over multiple P-frames. The display device further comprises a syntax parser for parsing the data stream to locate I-slices which make up an I-frame. A storage device is provided for storing the data stream. The display device also comprises an interface for receiving a command for a trick play mode feature. A processor associated with the syntax parser recovers the located I-slices from the storage device and assembles the recovered I-slices into one or more constructed I-frames. A decoder is provided for decoding the constructed I-frames to enable the trick play mode features.

International Classification:

G06F 21/57

Abstract:

A method is provided for authenticating two distinct objects using a single signature stored on one of the objects. On initiation of a hardware system a valid hash value can be generated based at least in part on a rootdisk file and a kernel can be modified to contain the valid hash value. On subsequent boots of the hardware system, the valid hash value stored within the kernel can be compared with a value of a potential rootdisk file and if the valid hash value and the rootdisk hash value match, the hardware system can proceed with the boot process.
