Hitachi To Display OB Advances At BroadcastAsia 2016

Hitachi Kokusai Electric has announced it will demonstrate its new DSNG OB truck for the first time in Asia at BroadcastAsia 2016, stand 1K2-01.

The vehicle offers operational flexibility and technical performance up to 4K Ultra-HDTV capabilities. It has been developed at the company's Istanbul-based design and engineering facility and is based on a Mercedes Vario vehicle. It can support up to six fiber, wireless system and PTZ cameras, while communication capabilities are provided through a 150cm satellite antenna and a 15m heavy duty mast. The vehicle houses more than 1km of cable on motorised drums allowing a network of remote cameras to be supported by the truck.

The vehicle provides 220RU of rack space and each truck is specified, designed and manufactured to meet the customer's OB needs. The unit provides the video, audio, transmission and infrastructure capabilities needed to create a stand-alone outside broadcast facility, and the technical specification of the unit allows for support of any broadcast signal from serial digital to HD and 4K.

Focus has been placed on the facility's internal design, monitor and control systems, air conditioning and weather proofing in order to create a comfortable working space irrespective of external environmental conditions. An on-board power generator ensures that the truck can operate anywhere, irrespective of power supply issues.

Also on display at the show will be Hitachi's Z100 series of portable digital microwave link systems that are designed to facilitate support coverage of temporary OB venues. High Definition and Standard Definition video and audio can be transmitted digitally from the field to a TV station, production site or central receive point during events.

The full-featured Hitachi Z100 Digital Microwave Link can transmit HD/SD-SDI, VBS (NTSC or PAL) video signals with the use of a new-design built-in HD/SD CODEC. Analogue signals are digitized into a transport stream and transmitted through the DVB-ASI interface.

The company will also display its range of cameras including the SK-HD1300 3MOS sensor HD production camera, and the SK-UHD4000 4K Ultra-HDTV broadcast camera system. The SK-UHD4000 is equipped with a 2/3-inch MOS sensor, enabling high sensitivity and resolution video images, while reducing power consumption.

Two transmitters will also be showcased by Hitachi at BroadcastAsia2016. The Parallax is a solid state UHF DTV transmitter, providing up to 100KW TPO ATSC. The transmitter features wideband Doherty technology, ensuring ultra-high efficiency, while hot-swap AC/DC rectifiers enable >90 percent efficiency.

Supporting low/medium power DTV transmitter applications is Hitachi's E-Compact. ISDB / DVB-T / T2 mode supports 600W – 7.0KW applications while ATSC mode supports 700W – 8.5KW applications. Advanced Digital Adaptive Pre-correction (DAP) helps streamline RF performance.

Hiroshi Mano, Hitachi Kokusai Electric Asia (Singapore) Pte. Ltd., said: "At Broadcast Asia, we will demonstrate a range of OB, broadcast system camera, digital link and compact transmitter technologies which combine to provide market leading technical performance with significant operating efficiency. From studio productions, right through to sports and other live events we have developed solutions that combine the highest broadcast quality with real operational cost savings. We look forward to a very busy show."
