Ikegami Builds 8K Mobile Production Truck for NHK

Looking to stimulate the production of 8K content, heretofore seen as impractical for everyday broadcast business models, Ikegami said it has built the world’s first 8K OB production vehicle for Japan Broadcasting Corporation (NHK). The new vehicle is designed to operate as a complete mobile 8K broadcast production facility capable of producing television of unsurpassed picture quality, complete with 22.2 channel surround sound. Ikegami has produced more than 800 mobile television production trucks, mostly in the 1080i/50/60i or p format.

The 40-foot long 8K OB vehicle was delivered to NHK in September 2015. Its role will be to allow television audiences to experience the full reality of live events from wherever they choose to view.

In March 2015, Ikegami introduced its SHK-810 fourth-generation 8K television camera that was developed in co-operation with Japan Broadcasting Corporation (NHK). This is about one-tenth the size and weight of Ikegami's first generation 8K camera and offers significantly improved operability. The company's efforts to develop 8K broadcast production equipment have focused on achieving extremely high resolution combined with Ikegami's proven ability to deliver very wide dynamic image processing. 

The Ikegami-built NHK truck features a 16-input production switcher, 8K (and 4K9 router, up to ten Ikegami 8K cameras and an 8K slow motion replay system.

In Japan, the road map for 8K broadcasting announced by the Ministry of Internal Affairs & Communications specifies that trial broadcast transmissions will be conducted in 2016. Regular 8K broadcast services are planned to begin in 2018. 



Many elements of 8K television production infrastructure are much larger in size, power consumption and number of cables than their HDTV equivalent. This is because 8K broadcasting production captures 16 times more image information than HDTV. Organizing an 8K OB vehicle is therefore much more challenging than designing and producing traditional OB vehicles.



The 8K OB vehicle produced by Ikegami delivers extremely high quality and high reliability in a compact size. The vehicle's specifications allow operation not only in Japan but worldwide so it can be operated for global sporting events such as the Olympic Games. It can be expanded another three feet to accommodate additional equipment as required.
