3.12.3.3. AFV HEX GPI Encoding
AFV HEX GPI encoding is designed to permit separate audio follow video switch selection for both V1 and
V2 busses. Four inputs are encoded to select one of the 12 inputs for the AFV1 group. Four inputs are
encoded to select one of the 12 inputs for the AFV2 group. Two GPI inputs perform the switch to one of
the AFV groups. There are four GPI inputs available for user defined functions.
