Grass Valley, previously known as Grass Valley Group, is a subsidiary company of the French company Thomson. Grass Valley produces technology for the broadcast and film markets, from acquisition through production, postproduction, and transmission.

History

Grass Valley was founded as a tiny R&D company in 1958 by Dr. Donald Hare in the small town of Grass Valley, California, in the foothills of California?s Sierra Nevada range. Hare chose Grass Valley after learning about it from his friend, Charles Litton Sr..^[1] In 1964, Grass Valley demonstrated its first video product, a video distribution amplifier, in a hotel room at the National Association of Broadcasters convention. By 1968, the Grass Valley Group had introduced its first vision mixer, the flagship product that helped build the company?s reputation.

The company merged with Tektronix in 1974, and was very successful for the next fifteen years. Then Tektronix sold its video business to a private investor (Terry Gooding of San Diego, CA), who reincorporated it under the name Grass Valley Group Inc. The sale closed on September 241999.

In 2002, the French electronics giant Thomson SA acquired the Grass Valley Group.

Since coming under the ownership of Thomson, Grass Valley has merged its product line with the existing professional and broadcast products of its new parent company.

Broadcast Products

The company produced some of the first video disk server products on the market in the mid 1990s, marketed under the "Profile" brand and given the name "PDR" (Professional Disk Recorder). Based on Microsoft Windows NT and Wind River Systems VxWorks along with standard PC and custom video hardware, these machines were an instant hit providing up to four video input/outputs in a box about the size of a Betacam video recorder.

Grass Valley now offers a number of video server products. The previous Profile family, the PVS3000 and PVS3500, which supported high definition and standard definition video, is now being replaced by the K2 Media Server and Media Client system, which Grass Valley launched in 2005. Alongside the Profile and K2 products, Grass Valley also offers "iVDR" products, such as the M-Series, which are intended as full-featured replacements for analog video tape recorder (VTR) systems.

As well as video disk systems, Grass Valley markets switchers and effects systems, such as the Kayak Video Production Center and video routers.
