4K SDI Quad Module
4K SDI Quad Module

The ClearView Extreme 4K and ClearView Player/Recorder 4K 3RU systems house two CV-SDI-IO-4K2 modules as pictured above. The ClearView Shuttle 4K and ClearView Player 4K 2RU Portables house one CV-SDI-IO-4K2 module.

Latest product models are capable of up to 4096X2160p/60Hz, 8 or 10 bit 4:2:2, record or playback on four HDSDI 3G connections.

Each CV-SDI-IO-4K2 interface module houses four programmable serial SMB mini connections with a supplied quad BNC conversion cable for each Quad/HD interface. applying either 4K in quadrants or two sample interleave format selectable for input or output. Note: For HD operations #1 is input, #2 is input, #3 is output, and #4 is output.

One HDMI 2.0b output is available on each of the CV-SDI-IO-4K2 interfaces (cable included per interface ).

One shared set of three BNC analog output connections is supplied for analog playback of HD/SD formats for Component (Y, Pr, Pb), and SD formats in Composite or S-Video.

Digital audio AES/EBU inputs/outputs on BNC are also supplied via the breakout connector and cable as described below.

– Only ClearView Extreme 4K models sold after May of 2014 provide simultaneous input/output function of 4K formats on Quad HDSDI.
– HDMI output on systems sold before May 2014 with originally equipped CV-SDI-IO-4K interfaces provided HDMI 1.4 output in HD rates only. A cost effective upgrade for replacement of original CV-SDI-IO-4K to the new CV-SDI-IO-4K2 (2 modules) are available for pre-May 2014 ClearView Extreme 4K systems.
– On Extreme 4K models sold before May of 2014 the higher 4K rates, with original CV-SDI-10-4K interface modules, of 29.97, 30, 50, 59.94 and 60 Hz are accomplished by using connections 1 and 2 from both modules for record and connections 3 and 4 from each for playback to a Quad/HD capable monitor along with the application of a sync generator (supplied).
– On all ClearView 4K and ClearView Player 4K models sold after May of 2014 one Quad/HD interface or HDMI output, on  the CV-SDI-IO-4K2, is providing all available 4K rates from 23.98 to 60 Hz (play or record) without the sync generator requirement.
