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. |

| 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)
