@Generated("io.github.jwharm.JavaGI") public enum VideoAFDValue extends Enum<VideoAFDValue> implements Enumeration
Enumeration of the various values for Active Format Description (AFD)

AFD should be included in video user data whenever the rectangular picture area containing useful information does not extend to the full height or width of the coded frame. AFD data may also be included in user data when the rectangular picture area containing useful information extends to the full height and width of the coded frame.

For details, see Table 6.14 Active Format in:

ATSC Digital Television Standard: Part 4 – MPEG-2 Video System Characteristics

and SMPTE ST2016-1

Notes:

1) AFD 0 is undefined for ATSC and SMPTE ST2016-1, indicating that AFD data is not available: If Bar Data is not present, AFD '0000' indicates that exact information is not available and the active image should be assumed to be the same as the coded frame. AFD '0000'. AFD '0000' accompanied by Bar Data signals that the active image’s aspect ratio is narrower than 16:9, but is not 4:3 or 14:9. As the exact aspect ratio cannot be conveyed by AFD alone, wherever possible, AFD ‘0000’ should be accompanied by Bar Data to define the exact vertical or horizontal extent of the active image. 2) AFD 0 is reserved for DVB/ETSI 3) values 1, 5, 6, 7, and 12 are reserved for both ATSC and DVB/ETSI 4) values 2 and 3 are not recommended for ATSC, but are valid for DVB/ETSI
