1. Project Background

A metro operator required a highly reliable and robust solution to distribute synchronized broadcast announcements, real-time arrival/departure schedules, critical emergency safety messages, and commercial advertising content across multiple stations and physical trains.

By deploying ORIVISION 4K Video Decoders directly into the PIS (Passenger Information System) hardware infrastructure, network IP streams are decoded with ultra-low latency and rendered seamlessly onto station and carriage screens in real time.

2. Customer Requirements

 Multimedia Broadcasts
Flawless delivery of audio-visual announcements, schedules, and dynamic media.
 Real-time Synchronicity
Instant display updates for next station arrivals and crucial timing info.
 24/7 Environmental Stability
Hardened performance to tolerate harsh, dusty, and high-vibration subway deployment environments.
 Multi-Screen Coverage
Large-scale network routing to screens distributed across kilometers of tracks and moving train carriages.
 Centralized O&M
Streamlined remote management capabilities to eliminate frequent physical on-site maintenance.


3. System Topology & Architecture

The network topology utilizes high-bandwidth Gigabit Ethernet backbones to link operations to the endpoints:

Control Center Side: Houses the core Broadcast Server, Streaming Server, and Management Platform. These elements aggregate the dynamic visual content feeds and forward them down the pipeline via a robust Network Switch into the IP Network infrastructure.

Stations & Trains Side (Endpoints): ORIVISION 4K Video Decoders pull specified IP streams directly from the local switches and output uncompressed, high-fidelity signals via HDMI onto terminal devices, including:


 Platform Displays for arrival countdowns and track directions.
 Announcement Displays dedicated to urgent public information notifications.

 Advertising Displays rendering scheduled monetization content layouts.

4. Solution Highlights

Real-time Decoding: Processes multi-protocol incoming streams with strict low-latency execution to secure absolute coherence across audio alerts and display overlays.

High Quality Output: Supports hardware-accelerated HDMI 1.4 video output up to 4K@30Hz, guaranteeing ultra-sharp textual font rendering and crisp, jitter-free video graphics.

Protocol Diversity: Native compatibility with SRT, RTSP, UDP, HTTP, HLS, and ONVIF protocols. Smoothly integrates with legacy broadcast infrastructure without transcoding bottlenecks.

Easy Management: Comprehensive embedded Web UI management. Allows remote batch configuration updates, firmware upgrades, and centralized health status checking.

Industrial Reliability: Fanless, ruggedized enclosure architecture optimized for thermal dispersion, enabling stable 24/7 continuous operations inside dense electrical cabinets.

5. Customer Benefits

Uncompromising Content Accuracy: Delivers flawless, real-time schedule adjustments and emergency announcements directly to passengers.

Unified Ecosystem Control: Ensures identical, highly synchronized frame updates across all stations and inter-city rail carriages.

Reduced Operational Costs: Remote configuration structures significantly limit manual field dispatches, driving down operational expenses (OpEx).

Elevated Commuter Experience: Clean, legible 4K screens coupled with consistent informational feeds massively boost citizen satisfaction metrics.
