Four-Channel HDMI H.265/H.264 Rack Encoder
Four-Channel HDMI H.265/H.264 Rack EncoderHDE-4265
BLANKOM HDE-4265 encodes four HDMI sources into H.265/H.264 IP streams in a 19-inch 1U chassis. Each channel provides one main stream and three substreams, with separate analog audio selection.

- HDE-4265 for 4 HDMI sources; specify stream profiles, audio selection and destination protocols
Technical Overview
HDE-4265 is the four-input version of the HDE-1265/HDE-4265 rack family. Each HDMI channel can use embedded audio or a separate stereo line input. The common family front image and the four-input connection view are labelled as reference illustrations.
Four output profiles per channel allow one source to serve different destinations. The main stream supports up to 1080p60; codecs and bitrate settings can be adapted to receiving devices. Four physical inputs and four profiles per input must not be confused with sixteen independent source inputs.
Gigabit Ethernet, Web management and SRT/RTMP/UDP-based delivery support rack-based IPTV integration. The published RTMP latency is protocol-specific and is not a guaranteed end-to-end delay for all output protocols. Plan receiver buffering and WAN behaviour separately.

Typical Applications
Four-source IPTV contribution
Encode four HDMI programme sources in one 1U chassis. Allocate embedded or analog audio per channel and deliver H.265/H.264 streams to compatible IP receivers.
Local distribution plus remote delivery
Use suitable output profiles for local UDP/RTP reception and remote SRT delivery. The four profiles per source share the original programme; they are not four additional physical inputs.
Rack integration of presentation sources
Connect HDMI presentation systems and select audio separately where needed. Check actual input timing, receiver codec and bandwidth for all enabled main/substreams before commissioning.
