Compact 4K60 SDI/HDMI IP Encoder
Compact 4K60 SDI/HDMI IP EncoderSHDE-400
BLANKOM SHDE-400 is a compact 12G-SDI/HDMI 2.0 encoder for H.265/H.264 IP distribution up to 4K60. Each encoder provides a main stream and a substream, with USB and microSD recording facilities.
Ordering Guide

Technical Overview
SDI and HDMI can be processed in parallel, with a maximum combination of one 4K60 source and one 1080p60 source per encoder. The two inputs are not two simultaneous 4K60 encoding channels. Embedded audio or the separate analog audio input is selected; the sources are not mixed.
The technical specification defines a main stream up to UHD/4K60 and a substream up to 1080p60 per encoder. H.265 and H.264 profiles allow the output to be matched to a receiver. Frame rates above 60 fps refer to lower image formats, not to 4K operation.
The unit combines broadcast inputs with IP delivery over Gigabit Ethernet. For RTMP platforms, select a codec accepted by that service; H.265 availability in the encoder does not imply H.265 acceptance by every RTMP destination. Recording and IP distribution must be configured for the selected source and media.

Typical Applications
UHD programme contribution
Encode a 12G-SDI studio source for a compatible SRT receiver. Select the bitrate, latency and receiver buffer for the real network; the product does not define a universal end-to-end delay.
Event distribution and recording
Feed HDMI or SDI from a production switcher, distribute the selected stream and configure USB recording. Check storage capacity and the selected recording format before an event.
Main and monitoring profiles
Use the main stream for UHD distribution and the 1080p substream for a compatible monitoring destination. Budget both active bitrates and protocol overhead on the Ethernet link.
