Shanghai Media Tech upgrades mobile production units with Grass Valley 4K/IP

Shanghai Media Tech runs the full gamut of production activities: pre-production, broadcast, post-production, network operation and maintenance, application development of new media and more. The China-based media company chose Grass Valley to provide a total 4K/IP solution for its OB van and EFP systems. Shanghai Media Tech’s mobile production units are equipped for any live programme or sports event as Asia’s largest all IP, 4K UHD OB vans.

“Transitioning our full system for the future of broadcast, 4K and IP, was a challenging task given the number of solutions we needed to upgrade in our OB vans,” said Yuanyue, team manager, Shanghai Media Tech. “Grass Valley’s total 4K/IP solution made the transition easy, as all of the solutions from camera to multiviewer were seamlessly integrated from the start. The entire system is designed to adapt to our changing needs and evolving industry trends, so we felt comfortable investing in this solution for years to come.”

Each OB van and EFP system is outfitted with multiple LDX 86N High Frame Rate/HD/3G/4K Software Upgradable Camera Platforms, Kayenne Video Production Center, GV Korona K-Frame V-series, GV Node Real Time IP Processing and Routing Platform, IPG-3901 Densité IP Gateway and GV Convergent IP/SDI Router Control & Configuration System.

Shanghai Media Tech purchased a total of 44 LDX 86N cameras, which feature native 4K UHD CMOS imagers that provide outstanding dynamic range performance, and the unique DPMULTRA technology that provides alternative switching to native HD pixels for global shutter operation. This investment gives Shanghai Media Tech the ability to capture razor-sharp live images with vivid colors and very low noise. For all types of programming, including live events and sports, the LDX 86N offers the highest sensitivity in both single speed and high-speed operation.

Kayenne K-Frame and GV Korona K-Frame V-series are also capable of handling varied content types. Both solutions offer multiformat support including 1080p and 4K UHD, providing Shanghai Media Tech with increased production flexibility. The Kayenne K-Frame also offers premium performance with the largest I/O footprint in the market, multiple multiviewer capability and up to 9 M/Es, accessible across two suites. At only 3 RU, the K-Frame V-series is ideal for compact mobile production spaces, providing enormous power but requiring no compromise on enterprise features. The switcher is modular in design and is available in 1, 2 or 3 M/E options.

Rounding out the 4K/IP system are Grass Valley networking solutions—GV Node, GV Convergent and IPG-3901. GV Node includes integrated processing, routing, aggregation and multiviewing in an all-in-one platform. GV Convergent provides next-generation network control, including multilevel routing for the proposed SMPTE ST 2110 essence-based flows and in-depth visualization and control of the IP fabric.

The complete control system is both infrastructure and signal format independent to adapt to unique facility needs and allow the Shanghai Media Tech team to make real-time modifications through an intuitive interface and custom system configurations. In combination with these solutions, the IPG-3901 gateway provides a robust feature set for normalizing variances in IP signals sent to GV Node and allows for distribution beyond Local Area Networks. Together, GV Node and IPG now offer the transfer of information with a distance of up to 40km between ports.
