BLANKOM HD Encoder Streamers Application Diagram

B2B application examples demonstrating how the rackmount architecture of the HDE-1265 and high-density HDE-4265 solve enterprise-grade video-over-IP requirements:

  • High-Density Central IPTV Headend Ingestion for Hotels: Large resort hotels and cruise ships require centralizing all streaming hardware inside a secure, temperature-controlled server room. By deploying the HDE-4265, the chief engineer can ingest 4 independent high-definition satellite receivers or local media players via HDMI into just 1U of rack space. The 4 independent motherboards convert the inputs into H.265 UDP Multicast transport streams, distributing 4 premium channels across the hotel network directly to edge Set-Top Boxes while keeping cable clutter to an absolute minimum.

  • Multi-Channel Corporate Town Hall and Cloud CDN Contribution: Global corporate headquarters frequently broadcast multi-language or multi-room executive briefings simultaneously. Utilizing the HDE-4265, the AV team connects 4 distinct camera feeds from different auditoriums into the single 1U chassis. Channel 1 and 2 can be configured to stream high-bitrate SRT feeds to international branch offices, while Channels 3 and 4 push optimized RTMP/RTMPS streams to public social video CDNs, all managed remotely via separate WebGUIs.

  • Academic Campus Video Distribution and Lecture Capture Hub: In centralized university network operation centers (NOC), the HDE-1265 is used as a permanent, standalone ingest point for the main university auditorium camera, while high-density HDE-4265 units handle secondary lecture halls. The incoming HDMI feeds are compressed into universally compatible H.264 or high-efficiency H.265 multicast streams, allowing students across the entire local campus network to access live educational feeds on any laptop or library terminal using open-source media players.

  • Municipal Government Command Center and Multi-Camera Logging: City council facilities and public safety command rooms utilize the HDE-4265 to centralize camera management. 4 independent high-definition HDMI outputs from security matrices, council chamber cameras, or map presentation computers are routed into the 1U rack unit. Each channel independently processes the video, broadcasting low-latency RTSP streams to operator dashboards while concurrently saving low-bitrate sub-streams to a centralized Network Video Recorder (NVR) for official compliance archiving.

  • Remote Broadcasting and DSNG Mobile Uplink Cabinets: Digital Satellite News Gathering (DSNG) vehicles and mobile production trucks operate in tight spaces where every centimeter of rack space matters. Mobile crews install the HDE-1265 for single-source remote feeds, or the HDE-4265 to handle up to 4 production cameras simultaneously. Driven by the rugged internal power supply that interfaces directly with the vehicle’s power inverter, the unit pushes secure, encrypted SRT streams over cellular bonding or satellite uplinks back to the main studio headend with absolute physical stability.

 

BLANKOM HDE-1265, and HDE-4265 IPTV encoders are designed for TV signal distribution in excellent quality over LAN and INTERNET.

While all three models share the same high-performance H.265/H.264 video processing core and software functionalities, they are engineered for different deployment environments:

  • HDE-265: A portable, compact desktop encoder powered via an external DC adapter, ideal for mobile or localized setups.

  • HDE-1265: A 1-channel professional encoder housed in a permanent 1U 19-inch rackmount chassis with an integrated, internal industrial power supply.

  • HDE-4265: A high-density 4-channel encoder that packs 4 independent HDE-265 motherboard modules into the same 1U 19-inch rackmount chassis, driven by a single, high-capacity internal shared power supply.

Each independent encoding channel natively supports digital video inputs and processing configurations up to 1920×1080 Full HD at 60 frames per second (1080p60). The internal system-on-chip (SoC) is backward compatible with 1080i60, 720p, and standard definition inputs, ensuring flexible multi-source integration.

The HDE-4265 operates on a completely isolated multi-blade architecture. Because it contains 4 physically separate motherboard modules, each channel features its own dedicated RJ45 Ethernet port, its own independent embedded Linux OS, and its own unique IP address. Network engineers can configure, reboot, or update each channel independently via its respective interface without causing any packet drop or interruption on the other 3 channels.

To ensure optimized network bandwidth consumption and universal client compatibility, every channel supports H.265/HEVC (Main Profile) and H.264/AVC (High/Main/Baseline Profile) video encoding. Audio extraction from the embedded HDMI line is processed using professional AAC-LC and MPEG-1 Layer II (MP2) standards.

Each independent channel incorporates a flexible multi-protocol streaming core. It can distribute compressed transport streams concurrently across multiple professional protocols, including UDP/RTP (Multicast and Unicast), SRT (Secure Reliable Transport), RTSP, HTTP, and RTMP/RTMPS, facilitating parallel distribution to local headends and public cloud CDNs.

Yes, each independent processing core incorporates a robust Dual-Stream encoding architecture. For any active HDMI input, the encoder can simultaneously generate up to 2 independent IP streams (Main Stream and Sub Stream). This enables managers to route a full-bitrate 1080p60 stream to primary local decoders while generating a lower-bitrate sub-stream for mobile viewing or local server archiving.

Portable encoders with external “power brick” adapters introduce significant cable clutter, thermal instability, and accidental disconnection risks inside heavy-duty server rooms. The HDE-1265 and HDE-4265 are engineered strictly for permanent 19-inch kabinet rack mounting. Their internal, industrial-grade power supplies ensure superior voltage regulation, efficient heat dissipation, and clean power cabling layouts required by telecom-grade standards.

Yes, an advanced internal hardware OSD (On-Screen Display) engine is integrated into each channel’s processor. Network administrators can overlay customized text lines, live system timestamps, corporate logos, or transparent watermarks directly onto each video matrix via the browser configuration panel in real time without causing any frame drops.

Every motherboard blade operates on a standalone, deeply hardened embedded Linux operating system with no external software requirements. Configuration parameters—such as stream bitrates (CBR/VBR), protocol targets, and resolution mapping—are managed completely remotely via an intuitive, responsive browser-based WebGUI (Web User Interface) through each channel’s respective Ethernet management interface.

Enclosed in a heavy-duty, ruggedized 1U metal chassis, these units utilize an advanced passive fanless thermal dissipation architecture per module, complemented by the structural ventilation of the 1U frame. By removing moving mechanical components—which represent the primary failure points in standard encoder hardware—the system achieves exceptional thermal resilience. This guarantees an outstanding Mean Time Between Failures (MTBF) path, making them fully rated for uninterrupted 24/7/365 deployment in central broadcast headends and telecom facilities.
