Abstract
Systems and method for processing v-chip data for an MPEG-2 decoder with personal video recording functionality are provided. In one example, a system that processes V-Chip data with personal video recording functionality may include a data transport engine and a video decoder. The video decoder may be coupled to the data transport engine and may be adapted to parse out V-Chip data.
Claims25
A method for processing V-Chip data with personal video recording functionality, comprising:
- ascertaining the V-Chip data from a video bitstream;
- associating the V-Chip data with the video bitstream;
- storing the V-Chip data and the video bitstream in a storage media;
- accessing the V-Chip data from the storage media;
- determining whether to display the video bitstream stored in the storage media as a function of the V-Chip data accessed from the storage media;
- and
- encoding the V-Chip data accessed from the storage media onto a video output if it is determined to not display the video bitstream.
A system that processes V-Chip data with personal video recording functionality, comprising:
- a data transport engine;
- and
- a parsing circuit coupled to the data transport engine, the parsing circuit being adapted to parse out V-Chip data;
- wherein the data transport engine is adapted to pass to the parsing circuit information identifying memory locations indicating V-Chip data reference locations.
A system for processing V-Chip data with personal video recording functionality, the system comprising at least one component adapted to, at least:
- ascertain the V-Chip data from a video bitstream;
- associate the V-Chip data with the video bitstream;
- store the V-Chip data and the video bitstream in a storage media;
- access the V-Chip data from the storage media;
- determine whether to display the video bitstream stored in the storage media as a function of the V-Chip data accessed from the storage media;
- and
- encode the V-Chip data accessed from the storage media onto a video output if it is determined to not display the video bitstream.
