Notes

Most commonly used broadcast recording format

 Generally used by broadcasters who are trying to maximize frequency spectrum and are not concerned with picture quality Predominantly used by Producers to emulate the film look when broadcast on Television, and for use as a recording medium, when the final output is film.

Popular formats explained
HDCAM

Color Sampling = 3:1:1, Bandwidth = 143 Mb/s, Compression 7.1:1, Precision = 8 bit, 1440x1080

 

HDCAM SR (two modes)

Color Sampling = 4:2:2, Bandwidth = 440 Mb/s, Compression 2.7:1, Precision = 10 bit, 1920x1080
Color Sampling = 4:4:4, Bandwidth = 880 Mb/s, Compression 4.2:1, Precision = 10 bit, 1920x1080

 

D5 (two modes)

Color Sampling = 4:2:2, Bandwidth = 250 Mb/s, Compression 4:1, Precision = 8 bit, 1440x1080
Color Sampling = 4:2:2, Bandwidth = 250 Mb/s, Compression 5:1, Precision = 10 bit, 1440x1080

 

DVCPRO100

(1080)
Color Sampling = 2.7:1.3:1.3, Bandwidth = 98,5 Mb/s, Compression 6.7:1, Precision = 8 bit, 1280x1080i30
Color Sampling =3:1.5:1.5 Bandwidth = 92 Mb/s, Compression 6.7:1, Precision = 8 bit, 1440x1080i25
(with a special test chart you can see the loss of color resolution, and the  25i color resolution of DVC PRO HD is slightly better than HDCam)

(4:2:2 is wrong! (cause it's referenced to Thin Raster) compared to HDCAM.  Everyone knows HDCAM's real color resolution is 3:1:1, but the resolution of 3:1:1 references to 1920x1080 Full HD, and you should always reference to the full raster)

 (720)
Color Sampling = 3:1.5:1.5, Bandwidth = 98,5 Mb/s, Compression 6.7:1, Precision = 8 bit, 960x720p60
Color Sampling = 3:1.5:1.5, Bandwidth = 82 Mb/s, Compression 6.7:1, Precision = 8 bit, 960x720p50

 

HDV

(1080)
Color Sampling = 4:2:0, Bandwidth = 25 Mb/s, Compression 22.5:1, Precision = 8 bit, 1440x1080

(720)
Color Sampling = 4:2:0, Bandwidth = 25 Mb/s, Compression 22.5:1, Precision = 8 bit, 1280x720

also here 4:2:0 is referenced to thin-raster, so compared to full raster it must be 3:1:0 or 3:1.5:0 depending on format and frame rate (at this moment there is no trustworthy information on HDV, and the table below is used as a reference, but that would be a 3:0.5:0.5 color sampling for HDV, However, this may not be right)
