Video Source Selection
Table 9-4 Video input overview
The High Definition Input (HDI) part has two input "ports". Each
port consists of a video input and an audio input. The ports are
named "DVI" (= AV5) and "AV4" and will be referred to using
these names.
The physical connectors for these inputs are:
•
AV4.
Three cinches that can be used for YPbPr with sync
on Y and two cinches for analog audio (left and right).
•
DVI.
One DVI-D connector and two cinches for analog
audio (left and right).
