My calcul for non compressed video signal :
Résolution (Full HD/UHD) x color depth (8, 10, 12 bits) x fréquency (24hz)

Full HD 4:2:0 8 bits : (((1920x1080x8)+(960x540x16))x24 )/8 000 000 = rate of 74,6 MB/s

Full HD 4:2:2 10 bits : (((1920x1080x10)+(960x1080x20))x24 )/8 000 000 = rate of 124,42 MB/s

Full HD 4:4:4 12 bits : ((1920x1080x36)x24 )/8 000 000 = rate of 223,95 MB/s

Compression factor of AVC and HEVC :
- The following link (

http://forum.blu-ray.com/showthread.php?t=3338) on Blu-Ray forum identified the average speeds recorded for the video tracks on Blu-Ray depending on the codec used (25Mbit/ s in the case of AVC / H.264 = 3.13 MB / s).

- We calculated the rate of uncompressed video encoded with the only video signal format for Blu-Ray (full HD 8-bit 4:2:0) and the result is 74.6 MB / s

- The average compression factor for AVC / H.264 is 74.6 / 3.13 or 23.85.

To simplify our calculations, we retain the medium compression factor of 24:1. The medium compression factor of HEVC will be 48:1 ( 50% most efficient ).

Etc ...
