A newly designed liquid-cooled ultra-high efficiency digital TV transmitter series is being showcased.
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, claimed NEC.
The wideband design allows for common usage among transmitters, reducing the need to stock a large number of spares.
Other featured products include 2K and 4K H.265 codecs. The VC-800/VD-800 is a hardware-based H.265 (MPEG-H/HEVC) codec which was developed to initiate optimum real-time coding of ordinary video resources. The VC-800/VD-800 provides better quality video than H.264 or MPEG-2 coding and can contribute toward saving transmission bit rate for a more cost-effective operation, said NEC.
