The device features 1x professional 12G-SDI (HD/SD-SDI backward compatible) and 1x HDMI 2.0 physical input interfaces. The hardware encoding architecture is designed to process the selected active video input source (either 12G-SDI or HDMI). From this single active video input, the device is capable of generating up to 4 independent IP streams, each with completely distinct encoding parameters.

The BLANKOM SHDE-400 fully complies with real-time professional 4K broadcasting and distribution standards. On the input stage, it losslessly accepts ultra-high-definition signals up to 4096×2160@60fps. The hardware encoding engine can deliver the main IP stream output at the exact same 4096×2160@60fps (4Kp60) resolution without any compromise on visual fidelity.

Single video input to “4 Independent IP Streams” output architecture is engineered with dedicated hardware multi-threading. You can broadcast the Main Stream in 4K UHD via UDP/Multicast to your local IPTV network while guaranteeing 99.999% continuous uptime on the secondary channels for independent SRT, HLS, or RTMP delivery.

Yes. The hardware video processor offers a highly flexible profile hierarchy. Each of the 4 assigned IP output streams can be individually configured using H.265/HEVC (Main Profile), H.264/AVC (High/Main/Baseline Profile), or MJPEG architecture. This enables operators to serve future-proof, low-bandwidth H.265 streams alongside legacy-compatible H.264 streams from the very same unit.

The product comprehensively supports all modern streaming protocols required by professional B2B network infrastructures and public internet delivery. The IP egress layer includes SRT (Secure Reliable Transport), HTTP, RTSP, RTMP, RTMPS, UDP/RTP (both Unicast and Multicast modes), FLV, HLS, and ONVIF. It provides outstanding stability particularly for multicast distribution within Local Area Networks (LAN).

To prevent packet loss and jitter effects over public internet links, the SRT protocol is natively integrated into the device. The SRT architecture deploys an intelligent ARQ (Auto Repeat Request) error correction mechanism. Furthermore, to ensure maximum stream confidentiality, the video payloads can be fully encrypted using industry-standard AES-128 or AES-256 bit encryption algorithms.

The device features a wide selection of professional audio codecs, including AAC, AAC+, AAC++, MP3, MP2, AC3, and G.711. For the audio source input, you can utilize the embedded digital audio from the 12G-SDI or HDMI signal, or inject external analog audio via the 2x 3.5mm analog stereo audio interfaces on the chassis to mix it directly into the encoded video stream.

Yes. For professional post-production and high-end broadcasting applications where color accuracy and smooth gradient transitions are critical, the SHDE-400 hardware natively supports 4:2:2 color sampling and 10-bit color depth. This specification eliminates color artifacts and ensures studio-grade signal processing.

Yes, the device is equipped with a physical USB 3.0 interface and a TF-Card (Micro-SD) slot for local storage and redundancy. While the SHDE-400 maintains uninterrupted live IP streaming, it can concurrently record the video onto NTFS, exFAT, or FAT32 formatted storage media in high quality. Additionally, with the embedded SAMBA server implementation, recorded files can be accessed directly over the local network.

Operating on a hardened, embedded Linux OS with advanced de-interlacing and sharpening filters, the SHDE-400 is fully certified for 24/7/365 mission-critical broadcast operations, delivering telecom-grade MTBF with zero service interruption.
