BLANKOM IGS-2000 ASI to IP Converter, Gateway Application Example

The BLANKOM IGS-2000 / IGS-4000 / IGS-6000 series consists of professional, bidirectional ASI-to-IP and IP-to-ASI gateways designed to bridge legacy broadcast distribution systems with modern IP transport networks. They ingest Asynchronous Serial Interface (ASI) transport streams from broadcast equipment and encapsulate them into linear IP streams, or conversely, receive IP streams and decode them back into physical ASI outputs via BNC interfaces.

The product family is structured hierarchically to meet distinct deployment scales within a standard 1U rack-mount chassis. The channel density scales across the series: the IGS-2000 handles basic-density conversion, the IGS-4000 addresses mid-tier multi-channel requirements, and the top-tier IGS-6000 model maximizes physical ASI BNC interface aggregation, satisfying high-capacity enterprise broadcast centers and telecommunication facilities.

Yes, depending on the software configuration and the specific hardware module layout selected during the project procurement phase, variants within this series support independent bidirectional data processing. This enables broadcast engineers to run simultaneous ASI-to-IP ingestion and IP-to-ASI egress processing through the same 1U chassis without crossing signal paths or causing processing bottlenecks.

Every physical ASI BNC port on the chassis operates at full broadcast line-rate, supporting a maximum throughput of up to 216 Mbps. Furthermore, the embedded processing fabric automatically detects, parses, and converts both standard 188-byte and legacy 204-byte (Reed-Solomon encoded) Transport Stream packet structures seamlessly, ensuring perfect signal compliance.

The egress streaming block complies strictly with professional telecom B2B IP networking specifications. It implements low-overhead, line-rate UDP and RTP encapsulation, supporting both Unicast and Multicast transport topologies. This ensures highly stable, low-latency distribution across gigabit local architectures or core telecom multi-protocol networks.

No, the processing delay is practically negligible. Because the gateway does not parse or process the upper-layer syntax of the Transport Stream (such as video decoding, audio parsing, or PID reindexing), it operates at wire-speed line-rate processing. The encapsulation of an incoming physical ASI stream into IP packets (and vice versa) happens instantly at the hardware/MAC layer, preserving the ultra-low latency required for live synchronization and real-time broadcast contribution links.

When performing IP-to-ASI de-encapsulation, the gateway utilizes specialized internal buffering algorithms to absorb network-induced packet jitter caused by IP routing layers. It accurately reconstructs the native PCR (Program Clock Reference) timing of the original Transport Stream, generating a perfectly stable, continuous physical ASI clock rate at the BNC output. This prevents buffer underrun or overflow errors on downstream legacy modulators or IRDs.

The series natively accommodates both Constant Bit Rate (CBR) and Variable Bit Rate (VBR) ASI transport streams. In ASI-to-IP encapsulation mode, the device encapsulates the incoming packet blocks transparently as they arrive at the physical BNC interface. If a VBR stream is ingested, the outgoing IP data rate dynamically scales to match the exact payload throughput, ensuring optimal bandwidth utilization on your IP backhaul without dropping empty or null packets that are critical for specific broadcast multiplexes.

Remote configuration, real-time input bit-rate tracking, port logging, and packet statistics are managed exclusively via an embedded WebGUI through a standard internet browser over a dedicated, independent 100M Ethernet management interface. This model line does not support SNMP management, prioritizing low-overhead web-based administration and keeping the control plane completely secure and isolated.

Built for continuous 24/7/365 operator uptime, all variants are enclosed in a rugged, standard 19-inch 1U rack-mount industrial chassis. Detailed Ordering Guides on irenis-blankom.com outline the available hardware matrix cards and options for dual redundant power supplies (AC/DC) to protect the distribution path against single points of failure in primary telecom facilities.
