High efficiency DTV transmitter and 2K/4K playout

A newly designed liquid-cooled ultra-high efficiency digital TV transmitter series and an integrated 2K/4K playout solution are being showcased by NEC.

NEC said the transmitters in this range are a direct response to increasing worldwide demand for electrical cost savings. The transmitters feature ultra-high efficiency on both the VHF and UHF bands, enabling broadcasters and network provider to dramatically reduce operational costs.

One new feature found on this series of transmitters is a lightweight wideband power amplifier. This newly designed PA weighs about half of what the previous models weigh, making it possible to be lifted by one person. The wideband design allows for common usage among transmitters, reducing the need to stock a large number of spares.

NEC said that a new user-friendly interface can be operated intuitively, even by non-expert personnel, while the minimisation of the main components and module help downsize space needs and thus site rental cost.

NEC added that a big focus at IBC is using its technology to reduce its customers’ total cost of ownership.

The company has more than 80 years of field experience in the design and implementation of end-to-end broadcasting systems. NEC has supplied products and solutions to customers in more than 100 countries. Notably, NEC supplied transmitters to the UK for the start-up of the world’s first commercial terrestrial digital broadcasting service in 1998, and recently the company has developed what it claimed is the world’s first hardware-based ultra-high definition encoder for commercial use.
