Overview

Velocix Multicast ABR is a carrier‑grade live‑streaming optimisation software designed for video service operators. It enables a single shared multicast stream to deliver live video to millions of concurrent viewers, and dynamically switches to unicast delivery when personalisation or targeted advertising is required. The solution is standards‑based (e.g., FLUTE, DVB, 3GPP) and supports ultra‑low latency live events (down to ~2 seconds or less) to enhance viewer experience and reduce network burden. It integrates with home gateways, set‑top boxes, edge devices or CDN proxies and is designed for large‑scale deployments by ISPs, telcos and OTT operators.

Features and Capabilities

• Multicast‑unicast switching: Enables operators to deliver live streams via a shared multicast channel for scaling efficiency, then switch to unicast per viewer when required (e.g., addressable advertising).
• Ultra‑low latency live streaming: Supports reducing glass‑to‑glass delay to ~2 seconds or less for live events like sports, enabling better sync with social media and viewer expectations.
• Standards‑based implementation: Implements industry standards including FLUTE (RFC 6726) and aligns with DVB, CableLabs, 3GPP specifications to avoid vendor lock‑in and ensure compatibility.
• Flexible client integration: Provides a lightweight proxy client that can be deployed in home gateways, ONTs, STBs, edge devices, or CDN edge proxies to maximise network efficiency and operate under constrained memory/footprint conditions.
• Forward error correction (FEC) and reliability: The client supports FEC, packet repair, congestion control to maintain stream quality even under network impairments.
• Scalable for millions of sessions: By delivering one shared multicast stream up‑link, network traffic upstream remains stable regardless of number of viewers; helps reduce infrastructure scaling costs.
• Integration with video ecosystem: Designed to work alongside origin servers, CDNs, recording / DVR platforms, and personalisation platforms from the same vendor or partner ecosystem.
• Time to market / deployment speed: Offers a pre‑integrated solution that helps operators launch live streaming services faster, relying on modular software.
• Use cases & application: Especially suited for live sports, large‑scale events, 5G video streaming networks, cloud‑DVR plus live viewing, where latency, scale and network cost control are critical.
