BLANKOM HD Encoder Streamers Application Diagram

B2B application examples showcasing how the 16-blade modular architecture, H.265 compression, and dual-power redundancy of the SDE-16265 solve large-scale video distribution requirements:

  • Carrier-Grade Central IPTV Headend Ingestion for Hotels and Resorts: Large-scale multi-building resort complexes or cruise ships require consolidating all video streaming infrastructure inside a secure central rack. By deploying the SDE-16265, engineers can ingest up to 16 high-definition video feeds into a single 3U cabinet space. By encoding the streams into H.265 UDP Multicast transport streams, the hotel slashes its local network bandwidth consumption by up to 50% compared to older H.264 setups, while the dual redundant industrial power supplies guarantee zero black-screen downtime for guest room TVs.

  • High-Density Multi-Camera Municipal and Courtroom Recording: Large municipal city halls or judicial complexes manage dozens of active cameras across multiple courtrooms and committee chambers simultaneously. The SDE-16265 acts as a centralized ingest hub, capturing 16 independent camera feeds in high-density H.265 format. Utilizing its 4-stream per channel capability, each courtroom blade can concurrently broadcast an RTMP feed to a public transparency portal, an RTSP feed to the main security monitoring wall, and separate high-efficiency master backup lines to an internal Network Video Recorder (NVR) for legal archiving compliance.

  • Centralized Enterprise Corporate Town Hall and Multi-Room Distribution: Multinational corporate headquarters often run independent video networks across different departments, training rooms, and executive boardrooms. By installing the SDE-16265 in the primary data center, the internal AV team routes 16 independent high-definition inputs directly into the 3U chassis. Selected blades can be optimized to stream secure low-latency H.265 SRT feeds over WAN to international branch offices, allowing high-quality video delivery over volatile public internet links with minimal bitrates.

  • Comprehensive University NOC Lecture Capture and Campus IPTV: In a university Network Operations Center (NOC), managing decentralized streaming hardware from 16 different campus lecture halls is highly inefficient. The high-density SDE-16265 centralizes this process by aggregating 16 independent high-definition camera and visualizer inputs into a unified 3U infrastructure. Each isolated module processes its own room feed into universally compatible H.264 or high-efficiency H.265 multicast streams, allowing students anywhere on the local campus network to stream live educational feeds using standard open-source media players like VLC on any tablet or PC.

  • Teleport Contribution and DSNG Mobile Broadcasting Vans: Digital Satellite News Gathering (DSNG) trucks and satellite teleport stations operate under volatile conditions with zero tolerance for power failures or excessive bandwidth costs. Broadcast crews install the rugged SDE-16265 inside their mobile rack units to handle up to 16 camera or production desk feeds simultaneously. Powered directly by the dual industrial power supply connected to independent backup generator circuits, the unit compresses the material into robust H.265 SRT and UDP transport streams, ensuring stable, bandwidth-optimized contribution transmission back to the main studio headend under heavy environmental demands.

The BLANKOM SDE-16265 series is a high-density, broadcast-grade hardware encoding and streaming solution designed for professional television studios, OB vans, master control rooms, and IPTV headends. It ingests high-bandwidth uncompressed digital baseband signals from multiple SDI sources simultaneously and compresses the video/audio payloads in real time into optimized digital IP transport streams.

To precisely address distinct system integration layouts and input density requirements, the product family consists of two specialized hardware versions:

  • SDE-16265: Features 16 physical 3G-SDI inputs equipped with 16 corresponding independent SDI loop-through outputs.

  • SDE-08265: Features 8 physical 3G-SDI inputs equipped with 8 corresponding independent SDI loop-through outputs.

Both the SDE-16265 and SDE-08265 incorporate a physical SDI loop-through output on each individual channel. The primary purpose of this architecture is to provide a zero-latency, completely unaltered pass-through of the original incoming SDI baseband video signal. This allows broadcast engineers and camera operators to route the source video directly to a local multi-viewer, confidence monitor, or local production hardware on-site, entirely eliminating the need for external, costly SDI distribution amplifiers (Splitters).

The hardware input interface is engineered to comply with high-definition professional broadcast standards, natively supporting 3G-SDI configurations with operational bitrates reaching up to 3 Gbps. This high-speed capability ensures uncompromised syntax extraction from full HD broadcast camera outputs and professional media matrices.

To ensure mission-critical hardware reliability and prevent continuous broadcast distribution failures, all models in the SDE-16265 series are standard-equipped with a dual power supply architecture featuring 1:1 redundancy. This professional layout ensures that if the primary AC power line drops or a power module fails, the secondary backup power supply instantly takes over the full operational load without causing any device reboot, stream dropped packets, or system downtime.

The advanced donanımsal encoding core comprehensively supports next-generation H.265 (HEVC) as well as standard H.264 (AVC) video compression protocols. By leveraging high-efficiency H.265 encoding algorithms, the device achieves up to a 50% reduction in required network transmission bandwidth compared to legacy standards while preserving the exceptional visual clarity and color depth required for professional source workflows.

Adhering strictly to professional B2B telecom specifications, the egress network processing tier supports an extensive array of streaming transport protocols. It natively delivers live streams over SRT (Secure Reliable Transport), HTTP, RTSP, RTMP, RTMPS, HLS, UDP, and RTP protocols in both Multicast and Unicast topologies, adapting seamlessly to local LAN distributions or public cloud ingest points.

For remote site contribution or transmission over unpredictable public networks, the series fully utilizes its integrated SRT (Secure Reliable Transport) engine. SRT applies advanced ARQ (Auto Repeat Request) packet recovery mechanisms to actively counteract network jitter and packet loss, while supporting industry-standard AES encryption to guarantee absolute end-to-end data security.

The audio processing block extracts digital audio directly from the embedded SDI input signals. It natively supports standard broadcast compression formats—predominantly AAC, AAC+, AAC++, MP3, and MP2—giving headend engineers full control over independent audio bitrates, volume gain adjustments, or stereo/mono configurations per stream profile.

Core system parameters, SDI input signal locking status, encoding bitrates, and egress IP routing parameters are configured and monitored exclusively via an embedded WebGUI using a standard web browser over a dedicated, independent Ethernet management interface. This setup eliminates any complex software installations, providing an isolated and highly secure control plane for network administrators.

The BLANKOM SDE-16265 is a high-density, carrier-grade 16-channel IPTV encoding system housed in a permanent 3U 19-inch rackmount chassis. It is engineered to consolidate 16 independent SDE-265 motherboard modules into a single central chassis. Driven by a dedicated dual industrial power supply architecture and featuring advanced H.265/HEVC compression, it serves as a premium micro-headend solution for telecommunication operators, high-density hospitality networks, and enterprise-grade multi-channel IP distribution.

Engineered for mission-critical reliability, the SDE-16265 is equipped with dual (redundant) internal industrial-grade power supplies configured in a hot-standby, balanced layout. If one power unit experiences an unexpected electrical failure or a phase drop, the secondary power supply instantly assumes the complete operational load. This prevents voltage fluctuations, system reboots, or packet drops across the 16 encoder blades, ensuring continuous service delivery.

The SDE-16265 utilizes a completely isolated multi-blade modular architecture. Each of the 16 internal motherboard modules functions as an independent hardware entity running its own standalone embedded Linux OS. Each blade features its own dedicated physical inputs, physical RJ45 network streaming ports, and unique IP addresses, allowing network engineers to independently configure, monitor, or reboot any single channel without interrupting the live streaming services of the other 15 channels.

Each independent SDE-265 module natively supports video inputs and processing configurations up to 1920×1080 Full HD at 60 frames per second (1080p60). The internal system-on-chip (SoC) layout is backward compatible with 1080i, 720p, and standard definition formats, allowing for flexible multi-source digital integration per slot.

To ensure maximum bandwidth efficiency alongside wide client compatibility, every module supports both H.265/HEVC (Main Profile) and H.264/AVC (High/Main/Baseline Profile) video encoding. Audio payloads are compressed utilizing high-fidelity AAC-LC and MPEG-1 Layer II (MP2) standards, multiplexing the stereo audio track directly into the outgoing digital IP transport container to preserve absolute lip-sync tracking.

Each independent SDE-265 motherboard blade incorporates an advanced multi-stream processing engine capable of generating up to 4 distinct, independent IP transport streams simultaneously from its single physical input source. This allows network operators to output a primary high-bitrate 1080p60 stream for primary display arrays while outputting up to three separate lower-bitrate sub-streams optimized for localized monitoring, mobile web proxies, or edge archival NVR loops.

Each internal encoder blade integrates a flexible multi-protocol streaming matrix. Every channel can distribute its processed transport streams simultaneously across various professional protocols, including UDP/RTP (Multicast and Unicast), SRT (Secure Reliable Transport), RTSP, HTTP, and RTMP/RTMPS, enabling parallel delivery to internal local IPTV networks and external public cloud CDNs.

Yes, every individual encoding channel features its own integrated hardware OSD (On-Screen Display) engine. Administrators can independently overlay customized text lines, live system timestamps, channel watermarks, or corporate logos directly onto each video stream matrix via the respective web panel on the fly without causing processing latency or stream stuttering.

There are no mandatory third-party software or SNMP agent dependencies. Because each blade operates on its own embedded firmware, all individual encoding bitrates (CBR/VBR), resolution downscaling, protocol destinations, and audio mapping are managed completely remotely via an intuitive, responsive browser-based WebGUI (Web User Interface) accessed directly through each channel’s respective Ethernet management interface.

Deploying 16 individual portable encoders creates severe server room vulnerabilities, including massive power cable clutter, multiple external “power brick” failure points, uneven airflow, and high accidental disconnection risks. The SDE-16265 solves this by centralizing 16 enterprise channels into a standardized 3U 19-inch kabinet rack footprint. Its passive thermal ventilation design, coupled with hot-swappable dual industrial power supplies, provides the physical stability, clean cable dressing, and mission-critical hardware protection required by telco-grade standards.
