SDI编码器 HDMI编码器 IPTV DCH5300EC PRO

DCH-5300EC H.265/H.264 HD Live Encoder

Product Overview
The DCH-5300EC is a high-definition live encoder supporting UHD/HD HDMI and HD SDI signal input/output. It enables simultaneous HDMI and SDI encoding/decoding, compatible with multiple signal sources such as satellite receivers, CCTV cameras, Blu-ray players, and set-top boxes. Equipped with H.265/H.264 encoding capabilities, it decodes local IP streams into H.264/H.265 formats for remote signal monitoring. Renowned for reliability and high performance, it is widely deployed in hotels, schools, apartments, clubs, and security surveillance systems

Technical Notes

1. Codec Efficiency:

• H.265 reduces bandwidth by ≈50% vs. H.264, ideal for 4K streaming

  .

• AAC-LC audio at 32–256 Kbps ensures high-fidelity stereo output

  .

2. Interface Specifications:

• HDMI: Consumer-grade, short-distance transmission (≤15m).

• SDI: Professional-grade locking interface (BNC), supports long-distance transmission (>100m)

  .

3. Deployment Flexibility:

• Dual power supply and rack-mount design suit 24/7 operation in critical environments (e.g., security control rooms)

  .

• SRT protocol enhances transmission stability in high-latency networks

Key Technical Notes

1. Interface Differences:

• HDMI: Consumer-grade interface for short-distance transmission (≤15m).

• SDI: Professional-grade locking interface (BNC coaxial) with strong anti-interference, supporting transmission over hundreds of meters

  .

2. Intelligent Encoding:

• ROI: Allocates higher bitrates to key areas to enhance visual quality.

• AVBR: Dynamically adjusts bitrates to balance quality and bandwidth, ideal for unstable networks

  .

3. Resolution Limits: 2160P resolution requires HDMI input; data port is prioritized for management access to ensure bandwidth stability.
