VC/VD-7700 are half rack size encoder/decoder devices, employing NEC's original ultra-low delay technology. These devices support H.264 | MPEG-4/AVC High422 [email protected] and are equipped with DVB-ASI and IP interfaces. They can be used in various contribution systems like FPU, SNG, and IP network. They also feature powerful original error correction. The encoder can transmit high-quality video and audio signals even under low-quality IP networks.
The VC-7700 (encoder) and VD-7700 (decoder) are half‑rack sized devices that employ NEC's original ultra‑low‑delay technology for H.264/MPEG‑4 AVC High422 profile at Level 4.1. They support both DVB‑ASI and Ethernet interfaces and are intended for contribution systems such as FPU, SNG, and IP networks.
The units offer a range of video and audio codecs, including H.264 High422, MPEG‑2/4 AAC‑LC, LPCM, and Dolby AC‑3/E pass‑through. They feature Ethernet (10/100/1000 Base‑T) with SNMP, Telnet and HTTP management, compact 1U dimensions (44 × 210 × 450 mm), a weight of about 3 kg, and operate from 85‑264 V AC with a power consumption of 50 VA or less.
| Video codec | H.264 [email protected] (8‑bit) |
|---|---|
| Dimensions | 44 mm (H) × 210 mm (W) × 450 mm (D) |
| Weight | 3 kg |
| Power supply | 85 V to 264 V AC, 50/60 Hz |
| Power consumption | ≤ 50 VA |
| Operating temperature | 0 °C to 50 °C |
| Ultra‑low‑delay mode latency | ≈ 10 ms to 120 ms |
| Normal‑delay mode latency | ≈ 300 ms or more |
The codec provides approximately 10 ms to 120 ms of latency in ultra low delay mode.
The devices support SNMP, Telnet, and HTTP for network management.
