Application Examples
B2B application examples showcasing how the extreme channel density and SPTS architecture of the EMU-8500 series solve large-scale enterprise video requirements:
-
Ultra-High Density Central IPTV Headend for Mega Hotels and Cruise Ships: Large hospitality projects require routing massive channel lineups into a single, compact central server rack. By deploying the EMU-8524, the chief network engineer can ingest 24 independent high-definition satellite receivers or local media servers via HDMI into just 1U of rack space. The encoder converts these 24 inputs into 24 separate H.264 UDP Multicast SPTS streams, feeding the hotel’s network switch directly. Guest room Smart TVs can instantly tune into individual SPTS streams, maximizing channel variety while keeping server room footprint and power consumption to an absolute minimum.
-
High-Density Multi-Room University Campus and Education Broadcasting: Centralized university campus networks frequently distribute live lecture content or internal television programming from multiple rooms simultaneously. By installing the EMU-8516 in the primary network operations center (NOC), the university can pull 16 high-definition HDMI lines from 16 different lecture halls directly into one unit. The device outputs 16 independent multicast SPTS feeds, allowing students in student dorms, campus libraries, or overflow labs to view any of the 16 live classes using open-source media players (such as VLC) on any device.
-
Centralized Corporate AV Distribution and Digital Signage Infrastructure: Multinational corporate headquarters or massive shopping malls maintain multi-screen informational displays driven by centralized media players. Utilizing the EMU-8508, the internal IT team connects 8 separate digital signage players or executive presentation laptops via HDMI. The device encodes them into 8 separate SPTS multicast streams. Edge decoders or set-top boxes behind each display can be tuned to specific IP addresses, allowing different building zones to receive customized high-definition corporate content with tight temporal synchronization.
-
Municipal Government Chamber Multi-Camera Stream Consolidation: City council buildings and courthouse facilities use multiple fixed cameras to record public sessions, main chambers, and separate committee rooms. The EMU-8516 or EMU-8524 consolidates these lines by accepting up to 16 or 24 camera HDMI outputs within a single 1U device. The system converts the video matrix into separate SPTS UDP/RTP streams, allowing the city’s technical staff to route specific room streams directly to localized archiving servers or push them to WAN proxy nodes for public transparency logging.
-
Teleport Contribution and Master Control Room (MCR) Feed Monitoring: Satellite teleport facilities and master control rooms must monitor and route dozens of incoming local turnaround channels or studio outputs before satellite uplink. Deploying the EMU-8524 allows engineers to take 24 independent monitor HDMI feeds from the production desks and digitize them instantly. The independent SPTS IP output architecture makes it easy to map these 24 feeds directly onto professional multiviewer network displays, enabling operators to keep an eye on full 1080p channel status without overloading the broadcast infrastructure.

Engineering questions
10 questions answered by the people who commission these unitsFAQ (Frequently Asked Questions)
What is the primary operational design and purpose of the BLANKOM EMU-8500 series?
The BLANKOM EMU-8500 series is a family of professional, high-density hardware encoding appliances housed in a standard 1U 19-inch rackmount chassis. It is engineered to ingest multiple high-definition HDMI video sources, compress them utilizing broadcast-quality algorithms, and multiplex them directly into independent, low-latency IP streams to serve as a core infrastructure headend for telecom operators, hospitality systems, and enterprise networks.
What are the differences between the three distinct versions available in the EMU-8500 family?
The EMU-8500 series is available in three hardware configurations to perfectly scale according to project density requirements, while maintaining identical software functionality:
-
EMU-8508: Features 8 physical HDMI inputs and outputs 8 independent SPTS IP streams.
-
EMU-8516: Features 16 physical HDMI inputs and outputs 16 independent SPTS IP streams.
-
EMU-8524: Features 24 physical HDMI inputs and outputs 24 independent SPTS IP streams.
What is the significance of the SPTS IP stream output architecture in this series?
SPTS stands for Single Program Transport Stream, meaning that the encoder encapsulates exactly one television channel or video program per individual IP destination address. This 1-to-1 processing layout (e.g., 24 HDMI inputs mapped to 24 distinct SPTS streams in the EMU-8524) allows network administrators to route, switch, and filter individual channels across the network matrix with full freedom, preventing the bandwidth waste associated with bulky MPTS (Multi-Program) streams.
What maximum video input resolution and compression profiles are supported?
Each physical HDMI input channel on the EMU-8500 series natively captures progressive and interlaced high-definition resolutions up to 1080p Full HD at 50/60 frames per second. The internal encoding processor compresses the video payload utilizing industry-standard H.264/AVC compression profiles, ensuring clean pixel mapping and universal compatibility with downstream edge receivers.
How are the audio channels processed and multiplexed into the transport stream?
The encoder automatically extracts the digital stereo audio tracks embedded directly within each HDMI input line. It compresses the audio payload utilizing professional MPEG-1 Layer II (MP2) or AAC compression layers, multiplexing the compressed audio with the corresponding video components inside the TS container to ensure absolute, uninterrupted lip-sync synchronization.
Which network streaming protocols are natively supported for IP distribution?
To ensure smooth integration with corporate networks and telco networks, the EMU-8500 series supports professional broadcast protocols. It outputs the generated SPTS streams natively via UDP and RTP (supporting both Multicast for local LAN distribution and Unicast for directed point-to-point links) over its high-bandwidth Gigabit Ethernet data ports.
Does the EMU-8500 series support custom logo watermarks or text overlays?
Yes. The processing core integrates an internal On-Screen Display (OSD) customization menu for each channel. Network administrators can independently overlay customized text lines, channel identifiers, corporate logos, or transparent watermarks directly onto each individual video feed matrix via the web control panel without introducing stream stuttering or packet drops.
How is the encoder managed and monitored remotely?
The EMU-8500 series runs on a deeply hardened, lightweight embedded operating system. It does not require any external client software or unverified apps. All parameters—including input resolution monitoring, individual bitrates (CBR/VBR), PID editing, and output multicast IP addresses—are configured completely remotely via an intuitive, browser-based WebGUI (Web User Interface) over a dedicated RJ45 management port.
What is the reliability profile of the hardware under continuous 24/7/365 operational loads?
Built inside a rugged, 1U steel chassis with an industrial internal power supply layout, the EMU-8500 series features a highly efficient thermal design optimized for server room deployment. By eliminating complex modular sub-blades and optimizing passive ventilation paths alongside ultra-reliable cooling components, the chassis maintains low operational temperatures. This layout is designed for a long Mean Time Between Failures (MTBF) under continuous 24/7/365 commercial workloads.
Does this system allow manual adjustments of PID values and stream descriptors?
Yes, for professional broadcast headend alignment, the software interface gives engineers full control over advanced Transport Stream parameter fields. Operators can manually edit Service Providers, Service Names, Video/Audio PIDs, PCR PIDs, and PMT PIDs for each of the SPTS outputs, ensuring seamless compilation with strict operator-specific middleware tables or hotel IPTV server requirements.
