HD/SD Timing Generator

The 7600HD-REF reference and test signal generator is a high-stability standalone 1 RU unit for providing system timing. It has a complete set of reference signals, including a master genlock reference loop-through input. It can be used in either master or slave roles. A powerful feature is timecode generation, as well as a complete set of reference signals, allowing for a very compact timing solution. Reliability is a top feature of the 7600HD-REF with dual-redundant power supplies and the ability to interface to the 7620PX changeover unit for backup. The 7600HD-REF can act as an NTP server ensuring IT-based units keep in step with the broadcast infrastructure. The time generated can be set from GPS satellites through the 7600GPS option. This makes the 7600HD-REF an ideal unit for OB operation.

Hillsboro, Ore., November 25, 2013 — Brazil's Canção Nova, a non-profit Catholic Community located in Cachoeira Paulista in the state of São Paulo, is upgrading its broadcast infrastructure with a range of Grass Valley® solutions including five Maestro™ branding and master control systems, five Concerto™ 64x64 routing switchers, five GeckoFlex™ signal processing systems, and six K2 Summit® servers for optimized live event workflows. The system will be live in November and span five locations.
Hillsboro, Ore., November 12, 2013 — Bank TV, a satellite broadcaster in the Ukraine, has launched a complete, end-to-end high definition (HD) news production solution from Grass Valley® to facilitate the smooth delivery of its 24/7programming. At the core of the broadcaster's new structure is GV STRATUS® nonlinear media production tools for enhanced production and a streamlined workflow. GV STRATUS is being used in tandem with EDIUS® multiformat nonlinear editing software and GV Edge™ Integrated Playout System with K2 Edge™ playout nodes for 24/7 playout. This deal with Bank TV builds upon the recent momentum generated by Grass Valley in the Ukrainian broadcast market as well as traction gained by GV STRATUS in the EMEA region.
