NEC VC-7700, VD-7700 User Manual

VC-7700/VD-7700 H.264 Ultra Low Delay Codec

VC/VD-7700 are encoder/decoder of half rack size, employing ultra-low delay technology of NEC original. These devices support H.264 | MPEG-4/AVC High422 profile@Level4.1 and are equipped with DVB-ASI and IP. These can be used in a variety of contribution system like FPU, SNG and IP network. Also these are applied powerful original error collection. The encoder can transmit high quality video and audio signal even under the low quality IP network.
