 Miranda’s DVI-Ramp is a DVI to HD/SD video port, which enables graphics workstation operators to easily and instantly extract computer graphics in real-time as HD or SD video for post-production, or for live playout on-air.
The output of the workstation’s graphics card is routed to the DVI-Ramp via the single/dual DVI connectors. The DVI-Ramp extracts the portion of the graphics signal appropriate for the HD or the SD formats, using pixel to pixel mapping. The digital RGB signal is converted to YUV 4:2:2, using the appropriate color matrix, and the signals are output as HD-SDI or SDI. This signal conversion process takes less than a frame. The DVI-Ramp features separate programmable gamma look-up tables for the DVI and HD/SD signals and generates a TTL level vsync output that can be used to genlock the computer’s graphic card. The DVI-Ramp also has a reference input and a built-in frame synchronizer providing gen-locked video outputs, even if the graphics card does not have a vsync input. The compact, 1RU chassis can be rack or table–mounted. .........................................................
