Conversion Functions (per channel on IQUDC31 and IQUDC33)
Modes
Up, down, and cross conversion
Aspect ratio conversion
Synchronization
Linear frame rate conversion (option)
Conversion Processing
Still Process: Detects still images and applies an aperture with full
(progressive) vertical frequency response
Enhanced Still: Adds field motion detection to still process. Prevents
artifacts on moving repetitive patterns
Aspect Ratio Conversion (auto/manual) AFD (SMPTE 2016), VI (RP186), WSS (L23)

Audio Functions (per channel on IQUDC31 and IQUDC33)
AES Audio
Eight AES audio ports individually assignable as inputs or outputs. Inputs
individually available to any or all processing channels. Outputs (48kHz)
separately assignable to any processing channel.
AES input is auto-detected as PCM (32 to 96 kHz) or non-PCM (48 kHz
locked to relevant video input).
Embedded Audio
16-channel embedded audio processing.
PCM processing includes channel-level gain and delay compensation,
and channel-level routing with L/R swap and phase invert feature.
Non-PCM processing includes pair level routing and delay compensation.
Dolby E data is passed with delay to match the video, and co-timed audio
frame drop or repeat.
