Image Processing Reference
Table F-2 lists the level that are defined for MPEG-2:
F-2 MPEG-2 Levels
576 pixels (approx)
High 1440 (H14)
1152 pixels (normal aspect ratio)
1152 pixels (wide aspect ratio)
The SNR, Spatial, High, and Multi-view profiles are not relevant to video pro-
duction and therefore you will not encounter them very often when compressing
MPEG-2 is not very useful for Internet delivery.
Within these profiles, the levels define raster sizes.
Profiles and Levels Combined
A shorthand notation is used to describe these combinations. The abbreviated names for
profile and level are separated by an @ character. Of the 24 possible combinations, only the
following ones are defined as ueable at present:
F-3 Profiles and Levels
Mapping these together we get raster sizes and bit rates, as described in Table F-4.
