VC-870/VD-870 : H.265/HEVC Real-time Ultra Low delay HD CODEC

Encoder: VC-870Encoder: VC-870

Decoder: VD-870Decoder: VD-870

VC-870/VD-870 are hardware-based compact design half rack size CODEC, comply with H.265/HEVC Main422 10 Profile @High tier Level 4.1.
Supporting Chroma 4:2:2 format with 10bit encoding and NEC’s original developed encoding algorithm realize ultra low delay operation with high video quality transmission. Besides, MPEG-4 AAC ELD profile can reduce audio transmission bandwidth under low delay operation.
