Technologies and Protocols for Low Latency Streaming

Low latency streaming relies on specific protocols to reduce delay while maintaining a balance between performance, reliability, and scalability. Knowing how these protocols work can help corporate event planners create a streaming setup tailored to their unique needs.

WebRTC and Its Applications

WebRTC (Web Real-Time Communication) enables ultra-low latency by facilitating direct, peer-to-peer communication through web browsers - no extra plugins required. This makes it ideal for interactive corporate scenarios, like live Q&A sessions or real-time polling during executive meetings, where instant feedback is a must. Since WebRTC depends on direct connections, it's most effective for smaller, more focused events.

SRT (Secure Reliable Transport)

SRT offers a combination of low latency and high reliability, using advanced error correction to keep streams stable even in fluctuating network conditions. This makes it a go-to choice for high-stakes corporate events, such as earnings calls or product launches, where a secure and steady stream is non-negotiable. For event producers like Corporate Optics, SRT delivers professional-quality broadcasts that can adapt to tough network environments.

LL-HLS and LL-DASH

Low Latency HLS (LL-HLS) and Low Latency DASH (LL-DASH) are modern adaptations of traditional adaptive streaming protocols. By breaking video into shorter segments, they reduce start times and enhance the viewing experience. These protocols are highly scalable and compatible with a wide range of devices, making them perfect for large-scale events like company-wide announcements, shareholder meetings, or global product launches. While they don’t provide the real-time interactivity of WebRTC, their robust infrastructure ensures reliable content delivery to broad audiences. This foundation prepares the way for the upcoming discussion on optimizing network setups and hardware configurations.

Network and Hardware Setup for Low Latency

A solid infrastructure is the backbone of low-latency streaming. The right combination of network setup and hardware ensures a seamless corporate broadcast, avoiding the headaches of delays and interruptions.

Network Setup Best Practices

Start with wired connections using Cat 6 or Cat 6a cables for a stable and interference-free performance. To further streamline your network, create a dedicated segment specifically for streaming. This prevents competition for bandwidth from attendee Wi-Fi, registration systems, or other event-related tech.

If Wi-Fi is unavoidable, consider a mesh Wi-Fi system. These systems use multiple access points to eliminate dead zones. Properly position the mesh nodes in areas where presenters or cameras are located to maintain a strong and reliable signal.

For events where reliability is non-negotiable, internet bonding is a game-changer. By combining multiple internet connections - such as cellular, fiber, and cable - into one, you create a fail-safe system. If one connection drops, traffic is automatically rerouted, ensuring uninterrupted streaming.

Once your network is optimized, the next step is configuring your hardware and encoder settings for peak performance.

Hardware and Encoder Configuration

When it comes to latency, hardware encoders outperform software-based options. Devices like the Teradek Vidiu Pro or AJA HELO can achieve latencies as low as 500 milliseconds, whereas software encoders often add 2-3 seconds of delay.

The choice of video codec also plays a critical role. H.264 is the most universally compatible option, but H.265 (HEVC) offers better compression, delivering higher quality at lower bitrates. For ultra-low latency needs, the AV1 codec is worth exploring, though its device compatibility remains limited.

To minimize latency, set encoder buffer sizes to 500 milliseconds or less. However, thorough testing is essential to ensure your setup can handle network fluctuations.

Your encoder’s performance also hinges on how system resources are allocated. Assign specific CPU cores to encoding tasks to prevent interference from other processes. If you're using GPU-accelerated encoding, make sure your system has adequate cooling and power to maintain consistent performance, especially during long events.

For most corporate presentations, 30fps is a practical choice. It reduces data load while maintaining smooth and stable streams.

Once your hardware is fine-tuned, managing bandwidth and prioritizing streaming traffic ensures everything runs smoothly.

Quality of Service (QoS) and Bandwidth Management

To keep your stream uninterrupted, assign streaming packets the highest priority using DSCP marking or 802.1p tags. This ensures that background activities like email syncing or file downloads don’t interfere with your live broadcast.

When allocating bandwidth, it’s crucial to understand your stream’s requirements. For a professional 1080p stream, you’ll need at least 5-8 Mbps of dedicated upload bandwidth, with an additional 50% buffer to account for network overhead and fluctuations. For mission-critical broadcasts, many technical teams recommend setting aside 10-12 Mbps to maintain consistent quality.

Real-time monitoring tools are invaluable for identifying potential issues before they disrupt your stream. Track metrics like bandwidth utilization, packet loss, and latency. Setting up alerts for when upload bandwidth drops below 80% of your requirements gives you time to switch to a backup connection if needed.

Finally, your physical network infrastructure needs to complement your logical setup. Use enterprise-grade switches and routers with sufficient backplane capacity to handle multiple high-definition streams without bottlenecks. Gigabit connections should be standard, and for high-traffic environments, 10-gigabit uplinks are ideal to keep everything running smoothly.

Pre-Event Checklist for Low Latency Streaming

Getting everything ready before the event - testing systems, fixing potential issues, and preparing backup plans - is key to delivering a smooth low latency streaming experience.

This means testing everything - network, hardware, and software - under conditions that mimic the live event. Don’t forget to check how your stream performs across different devices and browsers to ensure a consistent experience for your audience.

Pay close attention to critical performance metrics like network stability and audio-video synchronization. Use this data to fine-tune your setup and address any issues well before going live.

Identifying and Fixing Bottlenecks

Use rehearsals to identify and address any performance bottlenecks. Check that your network and hardware can handle the load without slowing down or failing. If problems arise, revisit your configurations and optimize where necessary. Fixing these issues early gives you the time to refine your setup and avoid surprises during the live event. Once resolved, implement backup measures to further secure your stream.
