AFD
transmits data in the VANC space of the SDI signal, enabling both 4:3 and 16:9
television monitors to optimally present video with preset ARC and safe area information.
Without AFD, converted video may appear distorted or “cut off” when it appears on
different monitors.
See
on page 32 for a comparison of AFD and non-AFD aspect ratio conversion.
Figure 3-6.
AFD and Non-AFD ARC
VI
provides embedded code in 525-line and 625-line component digital video signals. This
code makes it possible for picture and program related source data to be carried in
conjunction with a video signal.
WSS
is embedded code in a 625-line system. It contains information on the aspect ratio
range of the transmitted signal and its position as it would appear on a conventional 4:3
display.
on page 34 and
on page 35 show the different AFD, VI, and WSS
on page 33 explains the meanings of the diagrams.
