Crystal Vision Updates Ten Picture Processing Apps

The latest picture processing software apps for its MARBLE-V1 media processor hardware is being shown by Crystal Vision all of which can work with IP, with SDI or with both IP and SDI at the same time.

The functionality offered by these apps – which support ST 2022, ST 2110 video and 31 different SDI standards – includes web browser keying, linear keying, picture-in-picture, clean switching, video delay, colour correction and up and down conversion.

“Their support for multiple signal formats gives the easiest possible SDI to IP upgrade, while also making the apps perfect for mixed SDI and IP installations as well as fully IP environments,” says the company. “One of the booth highlights at NAB will be the unique M-WEBKEY IP/SDI web browser keyer app, which provides a cost-effective alternative to a full graphics system. Other SDI products on show include the popular Cleanit profanity delays and Safire 3 real-time chroma keyer.”

Two of the new software apps being shown are keyers for channel branding as well as providing news, weather, advert and emergency information overlays for both IP and SDI infrastructures.

All of Crystal Vision's software apps run on the MARBLE-V1 media processor (a card housed in the Vision 3 frame) which features a powerful CPU/GPU processor, six bi-directional SDI connections and four 10GbE SFP+ network interface ports and allows different apps to be installed when needs change. The M-WEBKEY is described as an IP/SDI web browser keyer and is unique because it can key a web page on to a video input. It allows Flow 1 or a matte to be set as the background source, with the overlaid foreground source and key signal (which defines the graphic's location and transparency) coming from the URL that is entered. With traditional keying, the external key and fill have to be created and output as video which requires expensive dedicated character generator hardware, whereas keying a web page means that the key and fill source never become video.

“The M-WEBKEY plus a web designer and web server could provide all the graphics for a channel – saving broadcasters money compared to a traditional graphics system,” says Crystal Vision.

For those wanting a more traditional linear keyer which uses video sources for the background, key and fill, the new M-KEY software app is available – which can be used with IP, with SDI or with both IP and SDI at the same time. It allows Flows 1, 2 or 3 or a matte to be used as the background, and Flows 1, 2, or 3 to be used as the key signal and foreground overlay. Features include fades, masks, cropping and signal monitoring, along with a framestore synchroniser and up to ten frames of video delay to help sort out any timing issues.

Also being launched at the show is the M-PIP software app, an IP/SDI dual picture-in-picture device. The M-PIP has been designed for IP or SDI playout applications that need one or two picture-in-picture boxes to be inset on the main programme. It allows two input flows to be sized, positioned and cropped in advance (with edge softness and border generation available), and then layered – when required, using preset recall – over either the third input flow or an internal matte generator.

Crystal Vision's clean routing switches include launch of a dual channel IP fail-safe routing switch that also works with SDI. Including two independent 2 x 1 switches, the M-SAFESWITCH-2 software app has been designed to guarantee a clean switch. With a full framestore synchroniser on each input (plus the ability to delay the earliest arriving input by up to ten frames), it can correct for any timing difference between the two inputs – resulting in no disruption to the output picture when a switch takes place. Further protection comes from the user-defined timing source priority for redundancy, with the option of selecting from the two analogue references on the Vision 3 frame as well as PTP master and backup signals – should the main syncs become invalid, it will automatically switch to the specified backup syncs.

Ideal for planned maintenance switches to manually re-route a good signal around broken equipment, the M-SAFESWITCH-2 can also be used as a very sophisticated auto changeover switch, with the option of selecting from ten different fault conditions to automatically trigger the switch. These fault conditions are input missing, input video standard incorrect, active video black, active video frozen, video error, packet loss, audio group 1 missing, audio group 2 missing, audio group 3 missing and audio group 4 missing.

Crystal Vision is showing four new video delay software apps which work with IP, with SDI or with both and are designed for matching any system delays, such as those caused by virtual studio graphics, MPEG encoders and decoders, audio processing, HD radio links and satellite links. All include a framestore synchroniser and support PTP in addition to analogue references as a timing source. 

The M-COCO-2 is a dual channel IP/SDI colour corrector and legaliser software app and has been designed for manipulating colours to correct for camera or lighting problems or to standardise pictures shot at different times.

A final new software app being launched at the NAB Show is the M-UPDOWN-2 – a dual channel IP/SDI up and down converter. This is for any video-only application requiring format conversion in an IP infrastructure, it can also work with SDI or with both IP and SDI for hybrid installations.
