Low Latency, High Stakes: Delivering Real-Time Streams at Scale
Main Elements that Impact Stream Performance
Several factors – such as the codec used, network quality, device capabilities, and geographic location – play a critical role in shaping real-time streaming performance.
Video Codec Selection
The choice of video codec directly impacts both video quality and processing speed. Here are three commonly used codecs:
- H.264/AVC: Widely supported, offering efficient compression with minimal processing demands.
- H.265/HEVC: Provides better compression than H.264, but requires more processing power.
- AV1: Delivers the best compression rates but demands significantly higher processing power.
Your codec selection determines how quickly the video can be encoded at the source and decoded on viewers’ devices. For example, while H.265 is more efficient at lower bitrates, its higher processing requirements may lead to delays on less powerful devices.
Network Requirements
Network performance is another key factor, influenced by:
- Upload bandwidth at the source and download speeds on the viewer’s end.
- The network’s ability to handle congestion and sudden traffic changes.
Adjusting streaming settings to match current network conditions can help maintain quality during periods of instability or variability.
Device and Location Effects
Viewer devices and their geographic location also play a role in stream performance. Factors include:
- Device capabilities: Processing power, screen resolution, and available memory all affect decoding speed and buffering.
- Geographic factors: Proximity to servers, local network quality, and regional bandwidth availability can influence the viewing experience.
Using adaptive bitrate streaming (ABR) ensures the stream’s quality dynamically adjusts to match these varying conditions. This approach helps deliver a smooth experience across different devices and locations.
Stream Settings Setup
Fine-tune your streaming setup to strike the perfect balance between quality and latency.
Bitrate and Resolution Setup
Your bitrate and resolution settings depend on the type of content you’re streaming. High-motion content, like sports, demands higher bitrates to maintain sharp visuals. Here’s a quick reference guide:
| Content Type | Resolution | Recommended Bitrate | Ideal For |
|---|---|---|---|
| Webinars/Presentations | 720p (1280×720) | 2-3 Mbps | Static visuals or occasional screen sharing |
| Sports/Action | 1080p (1920×1080) | 4-6 Mbps | Fast-paced content needing clear detail |
| General Live Events | 1080p (1920×1080) | 3-4 Mbps | A balanced option for most scenarios |
Start with these settings and adjust based on your network’s performance.
Dynamic Quality Adjustment
Most streaming platforms use Adaptive Bitrate Streaming (ABR) to handle network fluctuations. ABR continuously monitors bandwidth and connection stability, automatically adjusting video quality to prevent interruptions. This ensures smoother playback, even when your network conditions change.
To make the most of ABR, configure multiple quality levels for seamless transitions. You’ll also need to choose streaming protocols that prioritize speed.
Fast Streaming Protocols
For low-latency streaming, WebRTC and LL-HLS (Low-Latency HTTP Live Streaming) are top choices:
-
WebRTC
- Delivers ultra-low latency (200-500ms)
- Adapts to network changes automatically
- Supported natively in most browsers
-
LL-HLS
- Offers consistent 2-3 second latency
- Scales effectively for large audiences
- Works well with Content Delivery Networks (CDNs)
Adjust your encoder settings to match the protocol. For WebRTC, set a keyframe interval of 2 seconds or less to allow rapid quality adjustments. For LL-HLS, aim for a segment duration of 2 seconds with partial segments at 0.5 seconds for the best results.

Network Setup for Better Streaming
Set up your network to ensure smooth, high-quality streaming with minimal delays. Here are some effective ways to enhance your streaming network.
Using a CDN
A Content Delivery Network (CDN) can boost streaming performance by storing and delivering content from servers located closer to your audience. To get the best results, consider a multi-CDN approach. This involves using local Points of Presence (PoPs), smart load balancing, and dynamic caching. These techniques help reduce delays and improve the overall streaming experience.
Advantages of Edge Servers
Edge servers take things a step further by reducing the physical distance between your content and your viewers. By placing these servers in key locations – like major cities or high-demand regions – you can:
- Cut down on data travel distance
- Decrease latency and enhance stream reliability
Placing edge servers in areas with heavy traffic ensures your service stays responsive, even during busy periods.
Prioritizing Streaming Traffic
Managing network traffic is just as important as distribution. To avoid buffering and interruptions, try these methods:
- Use Quality of Service (QoS) tags to make sure streaming packets get priority
- Allocate dedicated network resources and manage buffers to handle congestion effectively
These steps can help maintain a seamless streaming experience, even when network demand is high.
