4K IP Decoder with Mosaic Viewer

The BLANKOM 4K IP Decoder is an operator-grade hardware decoding unit designed for IPTV headends, broadcast control rooms, and professional AV distribution networks. It is engineered to ingest high-throughput digital IP transport streams from network sources and decode them in real time into pristine uncompressed baseband video signals for display monitoring or studio routing.

Yes, the BLANKOM 4K IP Decoder incorporates an advanced integrated Mosaic Viewer (Multi-Viewer) engine. A Mosaic Viewer is a hardware-driven feature that allows the decoder to capture and decode multiple independent incoming IP video streams concurrently, dynamically scaling and arranging them into a single, combined multi-window display layout (such as a split-screen matrix) on a single monitor screen.

The primary application of the Mosaic Viewer is professional confidence monitoring, quality control (QC), and visual surveillance within broadcast master control rooms (MCR), headend centers, and digital signage operations. It enables station operators and network engineers to visually audit up to four live television channels or stream backhauls simultaneously on a single display (4-way mosaic), entirely eliminating the need for separate, costly individual hardware decoders and physical video switchers for every single feed.

To interface seamlessly with commercial video matrices, studio switchers, and professional displays, the hardware egress tier is equipped with high-bandwidth physical outputs. It natively features a premium HDMI output supporting resolutions up to 4K Ultra-HD alongside professional broadcast-grade BNC SDI interfaces featuring embedded digital audio parameters.

The hardware processing pipelines are fully optimized to handle next-generation resolution targets, natively decoding ultra-high-definition content up to 4K Ultra-HD at 30 frames per second (4Kp30); HD streams are decoded at up to 1080p60. This ensures fluid motion rendering, exceptional edge sharpness, and precise color tracking critical for broadcast-level compliance monitoring.

The advanced hardware core features high-performance decoding pipelines that comprehensively support H.265 (HEVC) and H.264 (AVC) video standard compression profiles. This broad compatibility allows the device to parse high-bitrate primary streams as well as highly compressed edge streams while maintaining high pixel integrity.

Adhering strictly to professional B2B telecom networking specifications, the input network processing layer handles an extensive matrix of streaming protocols. It natively manages stream acquisition over SRT (Secure Reliable Transport), HTTP, RTSP, RTMP, RTMPS, HLS, UDP, and RTP encapsulation configurations, functioning perfectly across local multicast networks or secure public internet links.

When capturing live video feeds transmitted from remote fields or distant production sites over lossy public networks, the decoder leverages its integrated SRT (Secure Reliable Transport) protocol layer. SRT actively uses smart ARQ packet recovery to eliminate network jitter and packet dropouts, while supporting industry-standard AES decryption to protect secure incoming broadcast payloads.

The audio processing stage extracts and decodes multi-channel digital audio payloads embedded inside the transport streams. It natively processes standard broadcast acoustic formats—predominantly AAC, MP3, MP2, and AC3 (Dolby Digital)—offering flexible configuration modes for digital audio pass-through or local stereo downmixing.

Core system provisioning, incoming stream protocol mapping, mosaic viewer grid layout arrangements, and output video configurations are managed exclusively via an embedded WebGUI using a standard web browser over a dedicated, independent Ethernet management interface. This provides network administrators with a secure, isolated, and highly responsive web-based control plane.
