SBS Specifies Leader for UHD1 OB Truck

A new OB truck built for South Korea’s SBS, designed for UHD and South Korean roads, integrates Leader Instruments 4K test equipment in its TV production system.

In a project commissioned by South Korean's national television and radio network, Seoul -based SBS, three Leader LV5490 4K test instruments were installed in a new OB production truck, SBS UHD1. The vehicle was built by Broadcast Solutions GmbH in Bingen am Rhein.

SBS UHD1 is thought to be the world's first 12G-SDI single-link production vehicle. It uses the two-sample interleave UHD standard and accommodates up to 12, 4K/UHD cameras. It also offers 3G-SDI quad link monitoring gateways.

UHD1 measures 11.35m long, 2.55m wide during transit and expands to 3.75m. Weight is 27 tonnes. On-board equipment includes 12 Ikegami UHK-430 cameras, Ikegami 3 mix/effects vision switcher, Evertz routers, Studer Vista X audio mixer, Tascam audio storage and Riedel intercoms.

The new UHD1 undergoes acceptance testing at Broadcast Solutions GmbH.

SBS specified Leader LV5490 and LV5381 UHD instruments for the camera control suite where they will be used during pre-shoot alignment of video sources. They’re located on a sloping panel near the center of the CCU desk. The LV5490 signal monitors were chosen for their accuracy and versatility, plus their compactness which is a significant factor in any OB system design. They are used for high end analysis of the 12G single link UHD and 3G quad link UHD layer. The truck also uses three LV 5381 for operational monitoring. They deliver highly consistent measurements and are popular with SBS operators.

"South Korea was a very early adopter of UHD TV," comments Broadcast Solutions CTO Rainer Kampe. "This new truck, UHD1, is based on the Alphaline variant of our Streamline OB vehicle family. It is designed for use by up to 17 operating staff. Alphaline comes with special workplace design, room concept and reduced length in order to cope with the special conditions of South Korean roads."
