Crystal Vision Unveils Video Delay And Color Correction Apps

The updates are for its MARBLE-V1 media processor hardware and offer functionality such as video delay, colour correction and IP to IP processing with different versions available in an IP, SDI or mixed SDI/IP environment.

Half of the sixteen software apps being launched at IBC are video delays. These are available with different numbers of channels (single or dual) and delay lengths as well as either SDI, IP or both SDI and IP connectivity and all include a framestore synchroniser allowing engineers to delay and synchronise at the same time.

Claimed by Crystal Vision as the industry's first video delays to offer IP connectivity, the VIVID1-IP app is a single channel IP video delay while the VIVID2-IP is a dual channel IP video delay. Four apps are available for those working in mixed SDI/IP environments: the VIVID1-IP-SDI (single channel) and VIVID2-SDI-IP (dual channel) combined SDI to IP gateways and video delays, along with the single channel VIVID1-IP-SDI and dual channel VIVID2-IP-SDI which are combined IP to SDI gateways and video delays.

Finally, the single channel VIVID1-SDI and dual channel VIVID2-SDI introduce an SDI video delay to the Vision frame system for the first time while offering an upgrade path to IP and a lower price than the Indigo frame versions.

All the video delay apps are suitable for matching any 3Gb/s, HD or SD extended system delays, such as those caused by virtual studio graphics, MPEG encoders and decoders, audio processing, HD radio links and satellite links. The single channel versions provide up to 800 frames of video delay, which is 16 seconds in 3Gb/s and 32 seconds in HD and SD. The dual channel versions provide up to 400 frames of video delay per channel, therefore eight seconds in 3Gb/s and 16 seconds in HD and SD. The apps with IP connectivity work initially with SMPTE ST 2022 with future upgrade to ST 2110 video.

The other eight software apps making their debut at IBC are color correctors for manipulating colors to correct for camera or lighting problems or to standardise pictures shot at different times. They are also available in single and dual channel versions and with either SDI, IP or both SDI and IP connectivity.

The single channel COCO1-IP and dual channel COCO2-IP are the broadcast industry's first IP color correctors. Also available are four apps which combine an IP gateway with color corrector, with the single channel COCO1-IP-SDI and dual channel COCO2-IP-SDI providing conversion from IP to SDI, and the single channel COCO1-SDI-IP and dual channel COCO2-SDI-IP allowing conversion from SDI to IP. Two SDI versions (the single channel COCO1-SDI and dual channel COCO2-SDI) give the Vision frame system an SDI color corrector for the first time, with the benefits of an easy upgrade path to IP as well as support for even more SDI video standards than the Indigo frame version, with 31 standards supported. The apps with IP connectivity work initially with SMPTE ST 2022 with future upgrade to ST 2110 video.

All eight apps offer a range of color correction tools including RGB gain, RGB lift, YUV gain, YUV lift, Video gain, Chroma gain, Chroma hue and both overall and individual RGB Gamma adjustment, while they also include a legaliser. Uses for the apps include adjusting the colors on in-shot monitors, being placed before an encoder to set the range of colors to be transmitted and the correction of computer-generated or post production outputs.

Other products on the Crystal Vision stand will include the new Cleanit video and audio profanity delay system, which allows a live content stream to be delayed by up to 20 seconds (in HD), giving the operator time to react and prevent the broadcast of unwanted or offensive video or audio material.
