Notes to Table 1–6 :
(1) The video formats support 4:2:2(YC’ B C’ R )/10-bit, 4:4:4(RGB)/(YC’ B C’ R ), 4:4:4:4 (RGB+A)/(YC’ B C’ R +A)/10-bit, 4:4:4(YC’ B C’ R )/12-bit,
4:4:4(RGB)/12-bit, and 4:2:2 (YC’ B C’ R )/12-bit mapping structures.
(2) 3G-SDI is similar to HD-SDI except the data bit rate is twice that of HD-SDI or approximately 3 Gbps.
OpenCore Plus Evaluation
With Altera’s free OpenCore Plus evaluation feature, you can perform the following
actions:
■
■
■
■
Simulate the behavior of a megafunction (Altera MegaCore function or AMPP SM
megafunction) within your system.
Verify the functionality of your design and quickly evaluate its size and speed
with ease.
Generate time-limited device programming files for designs that include
MegaCore functions.
Program a device and verify your design in hardware.
You are required to obtain a license for the MegaCore function only when you are
completely satisfied with its functionality and performance, and want to take your
design to production.
f For more information about OpenCore Plus hardware evaluation using the SDI, refer
to “OpenCore Plus Time-Out Behavior” on page 3–39 and AN 320: OpenCore Plus
Evaluation of Megafunctions .
