Abstract

Video analytics may be used to assist video encoding by selectively encoding only portions of a frame and using, instead, previously encoded portions. Previously encoded portions may be used when succeeding frames have a level of motion less than a threshold. In such case, all or part of succeeding frames may not be encoded, increasing bandwidth and speed in some embodiments.

Claims

1. A method comprising:

providing at least four input video channels for video analytics and encoding;

enabling one input channel for high definition video; and

enabling four input channels for standard definition video.

2. The method of claim 1 including allowing video vertical size to be changed.

3. The method of claim 1 including providing a gamma correction function using a look-up table.

4. The method of claim 1 including providing separate downscalers for encoding and video analytics.

5. The method of claim 1 including providing downscaler luminance and chrominance data to a frame formatter

6. A non-transitory computer readable medium storing instructions to:

provide at least four input video channels for video analytics and encoding;

enable one input channel for high definition video; and

enable four input channels for standard definition video.

7. The medium of claim 6 further storing instructions to allow video vertical size to be changed.

8. The medium of claim 6 further storing instructions to provide a gamma correction function using a look-up table.

9. The medium of claim 6 further storing instructions to provide separate downscalers for encoding and video analytics.

10. The medium of claim 6 further storing instructions to provide downscaler luminance and chrominance data to a frame formatter.

11. An apparatus comprising:

at least four input video channel frame capture units for video analytics and encoding;

one input channel frame capture unit to capture high definition video; and

four input channels frame capture units to capture standard definition video.

12. The apparatus of claim 11 said capture units to allow video vertical size to be changed.

13. The apparatus of claim 11 said apparatus including lookup tables coupled to said units to provide a gamma correction function using said look-up tables.

14. The apparatus of claim 11 said apparatus including separate downscalers for encoding and video analytics.

15. The apparatus of claim 14 including a frame formatter to receive downscaler luminance and chrominance data from one of said downscalers.

16. A system comprising:

a video capture interface including at least four input video channel frame capture units for video analytics and encoding;

a video encoder coupled to said interface; and

a video analytics functional and coupled to said interface.

17. The apparatus of claim 16 said capture units to allow video vertical size to be changed.

18. The apparatus of claim 16 said apparatus including lookup tables coupled to said units to provide a gamma correction function using said look-up tables.

19. The apparatus of claim 16 said apparatus including separate downscalers for encoding and video analytics.

20. The apparatus of claim 19 including a frame formatter to receive downscaler luminance and chrominance data from one of said downscalers.
