  • Page 5: Introduction

    Crystal Vision Introduction 1 Introduction CoCo HD is a 10 bit High Definition/Standard Definition digital colour corrector and legaliser, which allows independent digital image adjustments in YUV and RGB domains, essential for maintaining colour fidelity. CoCo HD passes all ancillary data, including embedded audio, transparently.

  • Page 6: Processing Modes

    CoCo HD is an excellent legaliser too. It has advanced correction for gamut errors, that will change any YUV colours that are illegal in RGB to be valid in RGB. CoCo HD legalises by reducing the colour saturation without changing the hue, processing the RGB components on each pixel at the same time and achieving a legal and natural-looking picture.

  • Page 7: Yuv Soft Limiting

    These transients can produce “overshoots” outside of the legal gamut range which can result in RGB errors being flagged downstream of the CoCo HD. Legalising these overshoots using a hard clip range may result in over clipping the video content.

  • Page 8: Black Cleanup

    Introduction Black cleanup A useful feature of the CoCo HD is its black cleanup control. The black cleanup works by returning any video Luma content that falls below a previously set threshold level to black. Sub black information is passed unaffected.
