Engineering questions
10 questions answered by the people who commission these unitsFAQ (Frequently Asked Questions)
What is the primary operational function of the BLANKOM SHDE-4000 series encoder streamer?
The BLANKOM SHDE-4000 series is a broadcast-grade, ultra-high-definition (UHD) hardware IP encoding and streaming platform. It is engineered to capture high-bandwidth baseband video signals up to 4K resolutions at 60 frames per second (4K@60fps) from professional production sources and compress them in real time into optimized digital IP transport streams for live distribution.
What structural and power configuration models are available within this specific 4K series?
To precisely address different density demands and infrastructure reliability requirements, the series consists of two distinct hardware choices:
-
SHDE-4000: Incorporates 1 independent encoder streamer engine inside a standard 19-inch 1U rack-mount chassis, equipped with a dual redundant power supply framework for mission-critical failover protection.
-
SHDE-4002: Incorporates 2 independent encoder streamer engines side-by-side within a single 19-inch 1U rack-mount case, optimized for space-saving density and sharing the chassis and the dual redundant power supplies; inputs and outputs of the two engines are fully independent.
Which physical baseband video input interfaces are provided on the SHDE-4000 series hardware?
Each encoder engine within the SHDE-4000 series is equipped with professional, high-bandwidth physical input options to bridge traditional studio hardware and digital IP networks. It natively incorporates a high-speed 12G-SDI BNC interface alongside a premium HDMI port, enabling robust connectivity with professional broadcast cameras, production switchers, and high-end media playback arrays. Both inputs can be encoded at the same time: one as main stream up to 4K60 and the other as sub stream up to 1080p60. Either input can be assigned to the 4K main stream.
Which video compression codecs and encoding profiles are processed by the SHDE-4000 hardware engine?
The device features an advanced hardware encoding core that comprehensively supports high-efficiency video codecs, including H.265 (HEVC) and H.264 (AVC) protocols. It supports deep color spaces and broadcast profiles, allowing operators to achieve a remarkable reduction in required transmission bandwidth while preserving the pristine clarity of 4K ultra-HD content.
What streaming protocols are natively supported by the egress network stage of the streamer?
Adhering strictly to B2B enterprise 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.
How does the SHDE-4000 series ensure video packet protection and error correction over public internet links?
For remote site contribution or transmission over unpredictable public networks, the series fully utilizes its integrated SRT engine. SRT applies advanced ARQ (Auto Repeat Request) packet recovery mechanisms to actively counteract network jitter and packet loss, and supports industry-standard AES-128 or AES-256 bit encryption for end-to-end data security.
Does the series support high frame rate processing for fast-moving content like live sports?
Yes. The hardware encoding pipelines are fully optimized to process true 4K UHD resolutions up to 60fps (2160p60). This high frame rate processing is critical for high-end live broadcast applications, such as live sports or high-action production environments, ensuring fluid motion rendering without ghosting artifacts or frame drops.
What professional audio compression standards and configurations are integrated into the platform?
The audio processing block extracts digital audio directly from the embedded 12G-SDI or HDMI input signals. It supports professional broadcast compression standards—predominantly AAC, AAC+, AAC++, MP3, and MP2—giving headend engineers control over audio bitrate and volume gain.
How is remote configuration and real-time operational status monitoring executed for the SHDE-4000 series?
Core system parameters, video input source telemetry, encoder bitrates, and IP streaming routes are configured and monitored exclusively via an embedded WebGUI using a standard web browser over the Gigabit Ethernet interface. This provides network operators with a highly secure, direct, and responsive web-based control plane.
What physical chassis standard and cooling framework protect the internal encoding modules?
Built for relentless 24/7/365 continuous deployment in broadcast master control rooms and primary telecom facilities, both the SHDE-4000 and SHDE-4002 models are housed in a rugged, standard 19-inch 1U rack-mount industrial metal enclosure. The chassis features intelligent active cooling fans and optimized thermal pathways to keep the internal processors running safely under maximum continuous 4K processing loads.
