View Patent ↗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.
1. 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.
2. The method according to claim 1 , further comprising receiving the video bitstream.
3. The method according to claim 2 , wherein receiving the video bitstream comprises receiving the video bitstream via a data transport processor.
4. The method according to claim 1 , further comprising transmitting the video bitstream to a soft decode engine.
5. The method according to claim 1 , wherein ascertaining the V-Chip data from a video bitstream comprises parsing the transport stream for the V-Chip data.
6. The method according to claim 1 , wherein ascertaining the V-Chip data from a video bitstream comprises parsing out the V-Chip data from the video bitstream with a decoder.
7. The method according to claim 6 , further comprising communicating the parsed out V-Chip data to a host.
8. The method according to claim 1 , further comprising, subsequent to ascertaining the V-Chip data, communicating the ascertained V-Chip data to a host.
9. The method according to claim 1 , wherein associating the V-Chip data with the video bitstream comprises associating, via a host, the V-Chip data with the video bitstream.
10. The method according to claim 1 , wherein accessing the V-Chip data from the storage media comprises accessing, via a host, the V-Chip data from the storage media.
11. The method according to claim 10 , wherein 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 comprises instructing, via the host, a decoder to decode the video bitstream associated with the V-Chip data.
12. The method according to claim 1 , wherein 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 comprises determining whether to decode the video bitstream stored in the storage media as a function of the V-Chip data accessed from the storage media.
13. The method according to claim 1 , further comprising, if it is determined to display the video bitstream, then displaying the associated video bitstream from the storage media.
14. The method according to claim 1 , further comprising, if it is determined to not display the video bitstream, then not displaying the associated video bitstream from the storage media.
15. The method according to claim 1 , further comprising, if it is determined to not display the video bitstream, then displaying a message based at least in part on the encoded V-Chip data.
16. 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.
17. The system according to claim 16 , wherein the parsing circuit comprises a soft decode engine, the soft decode engine being adapted to parse out V-Chip data.
18. The system according to claim 17 ,
wherein the data transport engine receives a transport stream and sends the transport stream to the soft decode engine, and
wherein the soft decode engine parses out the V-Chip data from the transport stream.
19. The system according to claim 18 ,
wherein the soft decode engine sends the parsed out V-Chip data to a host, and
wherein the host associates the V-Chip data with at least one of a video frame and an audio frame of the transport stream.
20. The system according to claim 19 , wherein the V-Chip data and the at least one of the associated video frame and the associated audio frame of the transport stream are stored in a storage media.
21. The system of claim 16 , wherein the parsing circuit is adapted to utilize the passed information to parse through user data to identify user data containing V-Chip information.
22. The system of claim 21 , wherein the parsing circuit is adapted to provide to a host the identified user data or a pointer to the user data.
23. The system of claim 16 , wherein the parsing circuit is a video decoder.
24. The system of claim 16 , wherein the parsing circuit is a host.
25. 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.
