DVI-I to HD-SDI Converter (No Scaling), Maximum Resolution 1080i, TV One 1T-C2-520

ITEM: 1TC2520

1T-C2-520 is a high performance converter that transforms DVI-D 720p or 1080i HD signals to HD-SDI for broadcast and professional use. An analog YPbPr or RGBHV signal can also be converted to HD-SDI. It also converts a standard analog YUV signal at 525i or 625i to SD-SDI. No scaling is performed within the unit, so the input vertical rates must be exact, per the chart below. The 1T-C2-520 is controlled via front panel buttons and an on-screen display. The unit is housed in a Desktop metal case and an optional Single/Dual Rackmount Kit is available.

Key Features of the 1T-C2-520

•    Full Digital Operation for SDI/HD-SDI Conversion
•    Serial Digital Video Output up to 1.485Gbits/sec

(1) Resolutions not listed in the Table are not supported.
(2) No scaling is provided so the output resolution and
vertical rate will match the input signal exactly.
(3) The output clock matches input clock with no jitter
reduction, so input jitter is transferred to the output.
(4)Video input timing must correspond to SMPTE 259M/
292M timing exactly or output will not be valid.
