CoCo 3G takes the innovative technology found in Crystal Vision’s other space-saving colour correctors and adds additional features, including the ability to work with 25 different video standards, enhanced picture processing, and optional integrated fibre input/output connectivity.
The colour corrector and legaliser works with 3Gb/s, HD and SD sources, and allows flexible whole picture adjustments in both the RGB and YUV colour spaces. The latter facility is said to make CoCo 3G ideal for manipulating the colours in any digital image to correct for camera or lighting problems, or to standardise pictures shot at different times. Popular applications include adjusting the colours on in-shot plasma displays, placement before an encoder to set the range of colours to be transmitted, and the correction of computer-generated or post-production outputs.
The extensive colour correction tools available include independent gain, lift and gamma in the RGB domain. Legalising features, meanwhile, include advanced correction for gamut errors which changes any YUV colours that are illegal in RGB to be valid in RGB 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. When there is no RGB processing, the signal is legalised in the YUV domain to make it RGB legal, avoiding the distortion inevitable when changing colour space.
The ability to handle 25 different video standards makes CoCo 3G suitable for use with any sources and for a wider range of industries. In addition to handling 625, 525, 720p, 1080i and 1080p video at the popular 50Hz and 59.94Hz data rates, CoCo 3G can also be used with the 23.98, 24 and 25 frames per second progressive video standards for film to HD video transfers.
Complemented by a choice of control methods, CoCo 3G includes three features designed to make the operator’s life easier. The first of these makes it easy to preview any adjustments: the auxiliary outputs can be connected to a monitor allowing the operator to either wipe horizontally or vertically between the processed and unprocessed signal, or to switch between input and output for a ‘before’ and ‘after’ comparison. The auxiliary outputs can also be used to highlight any pixels containing illegal signal values, making it easier to locate the problem and make any adjustments to equipment in the system. Finally, 16 presets can be used to save time: being able to store the precise adjustments for future use is ideal for those who need to continually correct a feed from the same camera, for example.
Philip Scofield, managing director of Crystal Vision, commented: “CoCo 3G has been produced as part of our policy of continuing to improve successful products. The latest version of our CoCo product range has processing improvements, as well as new hardware to enable it to work with 3Gb/s 1080p images. To make sure our customers get the best return on their investment we ensure our products work on video standards which customers will work with in the future, as well as with what they use now.”
