Engineering questions
9 questions answered by the people who commission these unitsFAQ (Frequently Asked Questions)
Can the BLANKOM SHDE-400 encode from both 12G-SDI and HDMI inputs simultaneously as two separate independent sources?
The device features 1x professional 12G-SDI (HD/SD-SDI backward compatible) and 1x HDMI 2.0 physical input interfaces. Yes. Both inputs can be encoded at the same time as two independent sources: one as main stream up to 4096×2160@60fps and the other as sub stream up to 1080p60. Either input can be assigned to the 4K main stream. In total the device generates 2 independent IP streams (main stream and sub stream), each with its own encoding parameters.
What are the maximum video resolution and frame rate limitations supported by the device?
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.
Can H.265 (HEVC) and H.264 (AVC) compression standards be used simultaneously (Simulcast) across the output streams?
Yes. The hardware video processor offers a highly flexible profile hierarchy. Main stream and sub stream can each be configured using H.265/HEVC (Main / Main10 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.
Which IP streaming protocols are supported by the SHDE-400? Does it support Unicast and Multicast?
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).
What protection mechanisms are provided for secure point-to-point video transmission over the public internet?
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.
What are the audio encoding capabilities, and can external audio sources be embedded into the video stream?
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 select external analog audio from the 2x 3.5mm analog stereo inputs on the chassis instead (the sources are selected, not mixed).
Does the device support broadcast-grade color sampling and bit depth standards?
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 10-bit input and encoding (H.265 Main10 profile) with HDR10 and BT.2020 wide colour gamut. This reduces banding in smooth gradients and keeps the colour range of HDR sources.
Is it possible to perform local video recording while simultaneously broadcasting live IP streams?
Yes, the device is equipped with a physical USB 3.0 interface and a TF-Card (Micro-SD) slot for local storage and redundancy; recordings can also be written to NFS or SMB/CIFS network folders. 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.
How are the management infrastructure and operational reliability structured for carrier-grade deployments?
Operating on a hardened, embedded Linux OS with advanced de-interlacing and sharpening filters, the SHDE-400 is built for 24/7/365 mission-critical broadcast operations, with a long service life and stable, uninterrupted running.
