FOR-A Debuts World’s First Dual-Link Switcher At Nab 2005

Continues to expand the flexibility and versatility of popular HANABI switcher series (May 09, 2005)

At NAB2005, FOR-A Corporation of America, a leading manufacturer of audio and video systems for the broadcast and professional video industries, continued to expand the flexibility and versatility of its popular HANABI switcher series with the introduction of HVS-Dual Link, the world’s first dual-link switcher. Featuring much of the same capabilities and specifications as the HVS-1000HS, the HVS-Dual Link is aimed at the film post production market. It will begin shipping in September.

Dual Link 4:4:4 video uses 2 HD-SDI channels to carry full color precision and color space (4:4:4 RGB 10bit). Current HDTV and standard definition video formats are 4:2:2 based, providing just half the color resolution of the original image. When running in Dual Link 4:4:4 the additional color information is carried on the second HD-SDI link, establishing the full color resolution of the original film or graphics, which is ideal for critical keying, heavy effects or feature film work.

A new member of the popular HANABI switcher series, HVS-Dual Link is a one M/E switcher supporting the dual-link formats, in addition to all HVS-1000HS features. It can be used as an HD-SDI dual-link video switcher or as a regular HD/SD video switcher by switching modes. It supports 4:4:4 RGB, 1080p/24, 23.98, 1080sF/24, and 23.98 in the HD-SDI dual-link mode as well as 1080i, 24p, 720p and standard definition formats in the HD/SD modes. Users have the option of adding true 3D DVE cards in a 4RU main unit offering a single DVE channel in the dual-link mode, up to two channels in the HD mode and up to four channels in the SD mode. HVS-Dual Link also offers optional color correction features, including process amplifiers and gamut correction. These options can be applied to the inputs and keyers.

“The key component of this switcher is its dual-link capability,” says Hiro Tanoue, Sales Manager/Eastern Region and Central/South America, FOR-A. “There is no single switcher on the market today that supports dual link. Other high definition switchers may support dual link, but they have to use two mainframes to support the exact color information to be processed. This is the first switcher that can handle a dual-link format in a single mainframe.”

The HVS-Dual Link comes standard with eight inputs, and can be configured for up to 14 inputs when used in the dual-link mode. In the HD/SD switchable mode, the same configuration offers 16 standard inputs and a maximum of 28 inputs. Two still pictures can be stored in frame memory in the HD-SDI dual-link mode and four in the HD/SD mode. Three channels of key are also provided as standard, including two chroma keys.
