NEC’s H.265 hardware codec for realtime 4K13 September 2014
The world’s first realtime hardware-based H.265 compliant encoder for 4K UHD broadcast is making its IBC debut with NEC in Hall 8.
NEC claimed its VC-8150/VD-8100 H.265 realtime codec makes it possible to transfer higher quality video with a lower bit rate over any platform and terrestrial, satellite, cable and IP network.
A 4K UHD total transmission solution with the H.265 4K/60P Codec is being demonstrated, including a DVB-T2 compliant transmitter, the NEC DTL-30 Series with power-saving Doherty amplifier technology.
NEC has been using the VC-8150/VD-8100 4K UHD codec through a number of pilot systems and has participated worldwide in 4K live transmissions. In May 2014, the VC-8150/VD-8100 was used at an experimental 4K UHD live transmission in collaboration with major Korean broadcaster MBC, during the KOBA exhibition in Korea.
In the UK, BBC Research & Development has been using NEC’s H.265 solution and transmitters in the closed trials at its laboratory to demonstrate 4K transmissions over the existing DTT platform, owned and operated by Arqiva. TV Globo in Brazil also used NEC’s 4K UHD encoder for live 4K UHD terrestrial broadcasting demonstrations
Also on show is the H.265 VC-800/VD-800 codec family for 2K and a full HD high sensitivity camera, the NC-H1200 Series.
NEC said the compact hardware-based VC-800/VD-800 codec reduces the costs for HD broadcast transmission by applying a lower bit rate than conventional MPEG-2 or H.264 technology, while delivering higher video quality.
Equipped with a 3CMOS image sensor, the NC-H1200 is a full HD camera for both fixed and portable TV production applications. NEC said the camera offers high sensitivity and delivers high-resolution colour even under demanding high contrast situations.
The camera’s newly developed visibility improvement technology helps deliver superior picture quality even under extremely dark conditions, while a ‘dehaze’ function is useful in foggy environments.
