E7i 12G SDI UHD 4K 60fps Network Encoder

Description

1. Product Overview
The E7i Series Encoders are professional broadcast-grade video encoders designed for live streaming, contribution, and distribution applications. They support 12G-SDI/HDMI inputs, H.265/H.264 encoding, and ultra-low latency streaming over IP networks. Three variants are available to suit different input and networking requirements.

2. Key Features

• Support H.265 (HEVC) and H.264 (AVC) encoding with advanced-level algorithms.
• Multi-version input configurations:
  Version 1: 1×12G-SDI or 1×HDMI2.0 input
  Version 2: 1×12G/3G-SDI In + 1×Loop Out, or 1×HDMI2.0 In + 1×Loop Out
  Version 3: 1×12G-SDI In or 4×3G-SDI Quad Link In
• Up to 4K@60fps 4:2:2 10-bit and 1080p@60fps 4:2:2 10-bit video processing
• Professional-grade streaming protocols: UDP, RTSP, SRT, HLS, and RTMP
• Bi-level / Tri-level genlock input for video synchronization (Version 2/3)
• VANC (RP-188/HLG/PQ10/HDR10) ancillary data encapsulation & pass-through (Version 2/3)
• Ultra-low latency (down to 40ms end-to-end, excluding network delay)
• Ultra-low bandwidth support: as low as 1 Mbps for HD, 4 Mbps for 4K
• Dual independent Gigabit network ports (Version 2/3) with separate data and NMS management interfaces
• Built-in LCD/OLED display for real-time device status and IP information
• Professional YCbCr 4:2:2 color space with 10-bit color depth
• NTP timestamp support for video stream synchronization
• Low power consumption design with high integration
• Broadcast-grade reliability with a wide operating temperature range
