4/8/12 HDMI IPTV Encoder and Streamer
EMU-9500
BLANKOM EMU-9500 offers 4, 8 or 12 HDMI inputs with H.265/H.264 encoding and SPTS IP distribution. Each four-input encoding module has format-dependent processing capacity; full-frame-rate H.264 capacity differs from H.265.
Ordering Guide
- Logo/text/QR insertion must be specified when ordering
- Select 4/8/12 inputs, required codec/resolution/fps per channel, output protocols and optional OSD
Technical Overview
EMU-9504, EMU-9508 and EMU-9512 provide one, two or three four-input modules. For each module, the specification lists four 1080p50/60 HEVC outputs but only two 1080p50/60 H.264 outputs. Four 720p50/60 H.264 outputs are specified. Input count must therefore be distinguished from simultaneous encoded format capacity.
Each channel is delivered as an SPTS, rather than an RF-modulated carrier. The IP output includes UDP, SRT and common streaming protocols. Network design must include all enabled services, their audio, transport overhead and the actual uplink capacity.
De-interlacing, noise reduction and sharpening are listed preprocessing functions. Logo, text and QR overlays are ordering options, not an assumed standard licence. The browser interface controls the unit and supports Ethernet firmware updates.

Typical Applications
Multi-channel IPTV headend
Encode compatible HDMI sources as separate SPTS services. Choose H.265 or H.264 capacity from the actual resolution table, then size the Ethernet uplink for the selected channel set.
Venue or campus TV
Deliver local information and programme sources to managed IP receivers. Multicast deployment requires an appropriately configured switching network and compatible decoders.
Remote service delivery
Use SRT or another supported protocol for a compatible remote receiver. Assess WAN capacity for the aggregate streams; an interface speed is not a guaranteed usable end-to-end rate.
