Miranda's DVI-RAMP2 is a DVI to HD/SDI video port and interface device. This converter enables graphics workstation operators to easily and instantly extract computer graphics in real-time as HD/SDI video for post-production, or for live playout on-air.
Conversion Process
The output of the workstation's graphics card is routed to the DVI-Ramp2 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.
Synchronization
The DVI-Ramp2 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.
DVI
The DVI-RAMP2 features single or dual head DVI input with loop out DVI Graphics.
Upgrade from DVI-RAMP
This upgrade allows HD-SDI video to be output along with SD-SDI per user application. RS-232 and Ethernet are offered via RJ-45 and USB connectivity.
