There are three different configurations for the 907-HDM2. They each balance the required video and data
inputs with the available optical bandwidth differently as shown in Table 3-1. Native HD-SDI uses 4:2:2 pixel
sampling. 4:1:1 sampling refers to full luminance sampling but reduced chrominance (color) sampling. 2:1:1
refers to reduced luminance and chrominance sampling. Ancillary data is typically used to embed audio and
closed captioning data with the HD-SDI video.

Notes:
1 = The required card configuration option (A, B or C) must be specified at time of order.
2 = Optimized sampling options (4:2:2, 2:1:1, 4:1:1) can be changed using the 907-DIAG-E card.
Option A: 907-HDM2 Dual Video (Optimized Sampling), default option.
The default option (dual video channel with 4:2:2 and 2:1:1 pixel sampling) provides one full HD-SDI video
channel on CH1 and one HD-SDI video channel with reduced luminance and chrominance samples on CH2.
Channel 1 in this case is typically used for video recording or continuous monitoring; channel 2 on the other
hand is typically used as a secondary channel that does not require all the color details of the video signal.
The quality of the secondary channel however, is still better than a standard definition or composite video
signal. This option supports up to six expansion cards and the ancillary data of the HD-SDI signal is not
transmitted over the optical link. Any of the three video sampling settings on this option can be switched in
real time using the 907-DIAG-E card.
