Content validation techniques

1. A video server comprising:

non-transitory machine memories or circuits comprising logic to cause the video server to operate to insert unique content identifiers into private packets of a digital program stream file at a time of loading the digital program stream file onto the video server; and

logic to insert unique session identifiers into the private packets of a digital program stream created from the digital program stream file as the digital program stream is being communicated to a data network.

2. The video server of claim 1 ,

wherein the logic to insert the unique content identifiers into the private packets of the digital program stream file as a result of loading the digital program stream file onto the video server further comprises:

logic to set a frequency at which the unique content identifiers are inserted at which the at least partially according to one or more of a RAID block size for the digital program stream file or a RAID layout for the digital program stream file.

3. The video server of claim 1 ,

wherein the logic to insert the unique content identifiers into the private packets of the digital program stream file as a result of loading the digital program stream file onto the video server further comprises:

logic to determine a frequency at which the unique content identifiers are inserted at the time when the digital program stream file is loaded onto the video server.

4. The video server of claim 1 ,

wherein the logic to insert the unique content identifiers into the private packets of the digital program stream file as a result of loading the digital program stream file onto the video server further comprises:

logic to insert the private packets into the digital program stream file at a frequency less than one packet every 10 seconds.

5. The video server of claim 1 ,

wherein the logic to insert the unique content identifiers into the private packets of the digital program stream file as a result of loading the digital program stream file onto the video server further comprises:

logic to insert the private packets into the digital program stream file at a frequency greater than one packet every 10 seconds and to adjust PCR values of the digital program stream to account for the private packets.

6. The video server of claim 1 ,

wherein the logic to insert the unique content identifiers into the private packets of the digital program stream file as a result of loading the digital program stream file onto the video server further comprises:

logic to remove a NULL packet from the digital program stream for each of the private packets that is inserted.

7. The video server of claim 1 ,

wherein the logic to insert the unique content identifiers into the private packets of the digital program stream file as a result of loading the digital program stream file onto the video server further comprises:

logic to store references to locations of the private packets in a tag file separate from the digital program stream file.

8. The video server of claim 7 ,

wherein the logic to store the references to locations of the private packets in the tag file separate from the digital program stream file further comprises:

logic to store the references to locations of the private packets in a trick play tag file.

9. The video server of claim 1 ,

wherein the logic to insert the unique content identifiers into the private packets of the digital program stream file as a result of loading the digital program stream file onto the video server further comprises:

logic to store references to locations of the private packets in the private packets themselves.

10. The video server of claim 1 ,

further comprising:

logic to insert the unique content identifiers at regular intervals in the digital program stream file.

11. The video server of claim 1 ,

further comprising:

logic to insert the unique content identifiers at irregular intervals in the digital program stream file.

12. The video server of claim 1 ,

further comprising:

logic to verify a value of the unique content identifiers in the private packets as the private packets are read for streaming.

13. The video server of claim 12 ,

wherein the logic to verify the value of the unique content identifiers in the private packets as the private packets are read for streaming further comprises:

logic to suspend transmitting the digital program stream when an invalid content identifier is encountered.

14. The video server of claim 12 ,

wherein the logic to verify the value of the unique content identifiers in the private packets as the private packets are read for streaming further comprises:

logic to apply, during streaming of the digital program stream, both of references to locations of the private packets in the private packets themselves, and the references to locations of the private packets in a separate tag file.

15. The video server of claim 1 ,

wherein the logic to insert the unique session identifiers into the private packets of the digital program stream as the digital program stream is being communicated to the data network further comprises:

logic to insert the unique session identifiers into the private packets of the digital program stream comprising the unique content identifiers for the stream.

16. The video server of claim 1 ,

further comprising:

logic to insert the unique session identifiers at regular intervals in the digital program stream file.

17. The video server of claim 1 ,

further comprising:

logic to insert the unique session identifiers at irregular intervals in the digital program stream file.

18. The video server of claim 1 ,

further comprising:

logic to set a frequency at which unique content identifiers are inserted at which at least partially according to one or more of a number of NULL packets in the content stream or a frequency of the NULL packets in the content stream.

19. The video server of claim 1 ,

further comprising:

logic to insert the private packets into the digital program stream file at a rate that is a least common denominator of a desired insertion frequency for the unique content identifiers and a desired frequency for the unique session identifiers.

20. The video server of claim 1 ,

further comprising:

logic to insert the private packets into the digital program stream file at a rate that is a smaller of a desired insertion frequency for the unique content identifiers and a desired frequency for the unique session identifiers.

21. The video server of claim 1 ,

further comprising:

logic to crawl content stored by the video server, generating checksums.
