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.

Claims

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; and

deriving a playback run time of the second content from header information included in at least one packet of the second content.

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; and

deriving a playback run time of the second content from header information included in at least one packet of the second content.

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; and

deriving a playback run time of the second content from header information included in at least one packet of the second content.

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 operations include:

comparing the run time derived against a time allotted for the second content; and

taking corrective action when the run time derived and the time allotted differ by an amount exceeding a threshold.

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