Grass Valley Unveils Kayenne

by Staff reporter for TV Technology, 04.20.2009

Grass Valley is at the NAB Show with the Kayenne Video Production Center. Kayenne is a new family of production switchers that integrates the features of the company's Kalypso and Kayak models and adds new advances that enable high-end creativity as well as streamline production workflow for HD projects.

Among the many hardware and software innovations Kayenne provides six keyers per M/E, 20 channels of DPM, including a 4-channel eDPM with two combiner outputs, Source Rules which associate keys with a source, a Device Control Module with jog wheel interacting with its Q-MEM cue library, and Define E-MEM providing finer control of E-MEM effects.

The Kayenne Video Production Center offers up to 96 inputs and 48 outputs in a single frame, which range from 1.5 to 4.5 Mix Effects. A half M/E with six linear/luminance keyers is standard in every model.

CONTROL PANEL

Kayenne has a new modular control panel. The hot-swappable panel modules can be removed and replaced quickly, without impacting on-air production. The panel's ergonomic design provides instant access to the many features. All of the buttons on the panel are RGB buttons so that color designates M/E, key, source, and function. Also, two rows of configurable OLED source name displays per M/E stripe provide increased legibility with the clearest and brightest displays available.

Kayenne's intuitively designed menu structure is accessed through a 15-inch (39 cm) high-resolution 1280x768 pixel touchscreen. The menu's user-focused navigation system is optimized for touchscreen use. It introduces the "favorites" and "history" familiar to users of Internet browsers and its semi-transparent pull-down tabs allow operators to make quick jumps between related menus. Additionally, no submenu is more than two levels deep.

All Kayenne switchers feature six keyers per M/E — that's 30 keyers in a 4.5 M/E switcher. Each full M/E has four full-function keyers (including optional chroma keys, preset patterns, masks, wipes, borders, etc) plus two linear/luminance keyers. Each full-function keyer also provides two video/key pages (frames) of storage for non-animated bugs without consuming Image Store outputs.

Kayenne internally converts up to 16 inputs and 8 outputs without tying up M/E resources through the use of the MatchDef and SetDef options. SetDef does not consume any M/E resources and both HD and SD outputs can be produced. Combining conversion with the FlexiKey and DoubleTake options provides a solution for multiple feeds of different formats which could include different graphics or backgrounds for each converted output.

Kayenne's Image Store for stills and clips offers six input and output channels and holds approximately one minute of HD storage. Grass Valley's new KacheBack technology allows fast archive/restore operations using real-time storage on an external DDR.
