High-speed, Progressive, Optical Digital Transmission and Camera Control System

The Camera Control Unit CU-HD1200 provides significantly reduced power consumption and improved functionality. SDI(1080p/1080i/720p/480i/ 576i )inputs/outputs are offered as standard. This flexible system is capable of providing many modern HD/SD-SDI video signals required by today's HDTV program production demands.

Constructed full complement of Serial Digital Interfaces is provided as standard.

Digital inputs/outputs:

  • HD-SDI OUT x8 or Dual Link-HD-SDI x4 [Embedded audio available]
  • HD-SDI or SD-SDI OUT x4 [x2/x2 Embedded audio available] (SD-SDI 16:9/4:3 switchable)
  • HD-SDI or SD-SDI WFM OUT x1 [Embedded audio available]
  • HD-SDI or SD-SDI PIX OUT x1 [Embedded audio available]
  • HD-SDI or SD-SDI RET In x4 [for VF]
  • HD-SDI or SD-SDI RET In x2 [for Floor Monitor] (HD-SDI 3G/1.5G switchable)

Analog inputs/outputs:

  • PROMPT IN x1
  • GL IN x1

High-performance SDTV down-converter

  • Due to the use of an independent and separate processor located in the CU-HD1200, detail can be adjusted for the SD video outputs without affecting the HD video signal outputs.
  • SD aspect ratio is switchable between 16:9 and 4:3.

HD up-converter

The HDTV up-converter for displaying the SDTV return signals in the HD Viewfinder is provided as standard with the CU-HD1200. The up converter is of a line-correction type capable of displaying 1080 effective scanning lines. In addition, AUX and Return color signals can be displayed in the TFT-LCD color viewfinders offered.

High-quality digital transmission using optical fiber cable.

An HFOC (Hybrid Fiber Optic Cable) is used to connect the camera adaptor (CA) and the camera control unit (CCU). The signals are transmitted using an optical serial digital transmission system that can be switched between 1080i and 1080p transmission modes to ensure high-quality transmission.

The effective HFOC length can be up to 4,000m (13,200 feet) with no utility power and up to 10km with normal single mode fiber (2 required per camera).

SDI Embedded audio Two channels of MIC audio can be embedded in HD-SDI/SD-SDI output.
