VC-970/VD-970 : H.265/HEVC Real-time Ultra low delay 4k CODEC

Encoder: VC-970
Encoder: VC-970
Decoder: VD-970
Decoder: VD-970

VC-970/VD-970 are hardware-based compact design half rack size CODEC, comply with H.265 Main10@L5.1 High Tier.

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.
