BLANKOM 16-Input UHD/HD HDMI IP Encoder

HDE-4275Q

BLANKOM HDE-4275Q has 16 HDMI inputs in four modules: eight inputs support UHD up to 3840 × 2160p30 and eight support up to 1080p60. Four Gigabit network ports distribute H.265/H.264 streams from the 1U chassis.

Technical Overview

The input matrix is important when planning a mixed UHD/HD installation. Each four-input module accepts UHD on inputs 1 and 2, and Full HD on inputs 3 and 4. The chassis is not a sixteen-channel simultaneous UHD encoder.

One main and three substreams per input provide separate distribution profiles. UHD operation is limited to 30 fps and Full HD to 60 fps on the main stream. The general 5–144 fps setting range depends on the lower-resolution format; it must not be interpreted as 4K144.

Four 1000 Mbps RJ45 interfaces serve the four-module architecture. Embedded HDMI audio or separate stereo audio is selected per source. Stream parameters, overlays and firmware are managed from the Web interface; the supplied application diagram is a family-level reference.

Typical Applications

Mixed UHD and HD source headend

Assign the eight UHD30 sources to inputs 1/2 of the four modules and the eight HD60 sources to inputs 3/4. This allocation preserves the published sixteen-input processing structure.

UHD display delivery and monitoring

Use a UHD main profile for a compatible primary decoder and lower-rate substreams for monitoring. Budget enabled traffic across the four Gigabit ports; the profile count is not an aggregate bandwidth guarantee.

Multi-source venue video network

Aggregate HDMI production and information sources into a 1U rack. Select H.265/H.264, frame rate and overlay settings for the actual display paths; UHD is limited to 30 fps.
