Introduction
9086 Functional Description
Video Functions Description
Video Processor
The 9086 provides full color processing control (luma gain and lift, chroma
saturation, and color phase) of the output video.
AFD Inserter
This function provides for assignment and insertion of AFD codes into the
SDI output video. Using this function, AFD codes in accordance with the
standard 4-bit AFD code designations can be applied to the output video.
This function checks for any existing AFD code within the received video
input. If a code is present, the code is displayed. When used in conjunction
with a separate downstream card capable of providing AFD-directed scaling,
the image can in turn be scaled in accordance with the AFD coding embedded
by this card.
The function also allows the selection/changing of the AFD code and
ancillary data line number for the outputted AFD code.
Timecode Processor
(See Figure 1-2.) This function provides for extraction of timecode data from
the input video, and in turn re-insertion of timecode data into the output SDI.
In this manner, timecode data can be preserved, even after format conversion.
The function can monitor the SDI input for supported timecode formats and
then select and prioritize among SDI VITC waveform and SDI ATC_VITC
formats (and audio/RS-485 LTC where licensed; see below). If the preferred
format is detected, the preferred format is used by the card; if the preferred
format is not detected, the card uses other formats (where available) as
desired.
The function also provides conversion between various timecode formats and
provides independent insertion and line number controls for each SDI
timecode output format.
Option +LTC allows bidirectional transfer and conversion
between VBI formats over SDI and audio LTC, as well as RS-485 LTC.
Audio LTC can be received or sent over a selected embedded channel.
