Abstract

A video processing method includes receiving a multimedia file including a first video file encrypted with a first compression algorithm and converting the first video file to a second video file, which is encrypted with a second compression algorithm. The method includes extracting, from the second file, video data indicative of at least one video characteristic of the second file and displaying the video data on a display screen or forwarding the video data to a content insertion server. The first video compression algorithm may be a MPEG-2 video compression algorithm and the second video compression algorithm may be an H.264 algorithm and/o an H.265 algorithm. The video data may include run time data indicative of a run time of the second video file, frame rate data indicative of a frame rate of the second video file, and pixel data indicative of a resolution of the second video file.

First claim

What is claimed is:

1. A content processing method, comprising:
receiving first content encoded in accordance with a first compression algorithm;
converting the first content to second content encoded in compliance with a second compression algorithm;
deriving a playback run time of the second content from header information included in at least one packet of the second content;
comparing the playback run time derived against a time allotted for the second content; and
taking corrective action when the playback run time derived and the time allotted differ by an amount exceeding a threshold.

2. The method of claim 1 , wherein the second compression algorithm achieves greater compression than the first compression algorithm.

3. The method of claim 1 , wherein the first compression algorithm comprises an MPEG-2 compression algorithm.

4. The method of claim 3 , wherein the second compression algorithm comprises a compression algorithm selected from a group consisting of: an H.264 algorithm and an H.265 algorithm.

5. The method of claim 1 , wherein the header information included in the at least one packet comprises a frame rate of the second content.

6. The method of claim 5 , wherein the header information further includes a frame count of the second content.

7. The method of claim 1 , further comprising:
before converting the first content to the second content, performing a quality check on the first content, wherein the quality check includes a loudness check.

8. The method of claim 7 , further comprising, responsive to detecting the loudness check failing:
invoking a loudness adjuster to make a loudness adjustment;
repeating the quality check; and
logging the first content as a pre-transcoding failure responsive to the second quality check failing.

9. The method of claim 1 , wherein the second content comprises an advertisement, the method further comprising:
inserting the second content into a programming stream.

10. A content processing server, comprising:
a processor;
computer readable storage, accessible to the processor, include processor executable program instructions that, when executed by the processor, cause the processor to perform operations including:
receiving first content encoded in accordance with a first compression algorithm;
converting the first content to second content encoded in compliance with a second compression algorithm;
deriving a playback run time of the second content from header information included in at least one packet of the second content;
comparing the playback run time derived against a time allotted for the second content; and
taking corrective action when the playback run time derived and the time allotted differ by an amount exceeding a threshold.

11. The server of claim 10 , wherein the operations include:
storing the second content in storage; and
forwarding the second content from storage to a content insertion server.

12. The server of claim 10 , wherein the header information includes frame rate data indicative of a frame rate of the second content, and pixel data indicative of a resolution of the second content.

13. The server of claim 10 , wherein the first compression algorithm comprises an MPEG-2 compression algorithm and wherein the second compression algorithm comprises a compression algorithm selected from the group consisting of: an H.264 algorithm and an H.265 algorithm.

14. The server of claim 10 , wherein the header information included in the at least one packet comprises a frame rate of the second content and a frame count of the second content.

15. A non-transitory computer readable medium including processor executable program instructions that, when executed by a processor, cause the processor to perform operations comprising:
receiving first content encoded in accordance with a first compression algorithm;
converting the first content to second content encoded in compliance with a second compression algorithm;
deriving a playback run time of the second content from header information included in at least one packet of the second content;
comparing the playback run time derived against a time allotted for the second content; and
taking corrective action when the playback run time derived and the time allotted differ by an amount exceeding a threshold.

16. The non-transitory computer readable medium of claim 15 , wherein the header information included in the at least one packet comprises a frame rate of the second content.

17. The non-transitory computer readable medium of claim 16 , wherein the header information included in the at least one packet comprises a frame count of the second content.

18. The non-transitory computer readable medium of claim 15 , wherein the first compression algorithm comprises an MPEG-2 algorithm and the second compression algorithm comprises an H.264 algorithm.

19. The non-transitory computer readable medium of claim 15 , wherein the corrective action includes replacing the first content with replacement content.
