Understanding Latency in Live Streaming: How It Works and Why It’s Not a Problem for TV Stations

Latency is a common concern for anyone involved in live streaming, but it’s often misunderstood. While some users may expect instant transmission, the reality is that a small delay in live streaming is normal and even beneficial in some cases. This article will explain what latency is, why it happens, and why it doesn’t negatively impact TV stations and live streaming setups using our RTMP servers.

What is Latency?

Latency refers to the delay between when a video is captured and when it appears on a viewer’s screen. In a typical live streaming setup, this delay can range from 5 to 30 seconds, depending on the encoding settings, internet speed, and the streaming protocol used.

Why Does Latency Occur?

Several factors contribute to latency in live streaming:

1. Encoding and Compression – When a live video is captured, it must be compressed before being transmitted to reduce file size and optimize bandwidth usage. This process takes a few seconds.
2. Network Transmission – The encoded video is sent from the streaming device to an RTMP server, which then processes and redistributes it to viewers. The physical distance and network congestion can add to the delay.
3. Buffering and Stability – Streaming platforms use buffering to ensure smooth playback, preventing interruptions due to fluctuating internet speeds. A small delay allows for consistent video quality.
4. Content Delivery Network (CDN) Distribution – If a CDN is used to distribute content to multiple locations worldwide, additional time may be required to process and serve the video to each viewer.

How Much Latency is Acceptable?

For most live streaming applications, a latency of 20 to 30 seconds is perfectly acceptable and standard in the industry. This is especially true for TV stations, webinars, educational streams, and entertainment broadcasts, where real-time interaction isn’t a priority.

For applications like video conferencing, online gaming, or financial trading, ultra-low latency solutions such as WebRTC or SRT are recommended instead of RTMP.

Why RTMP Streaming Works Well Despite Latency

RTMP (Real-Time Messaging Protocol) remains the industry standard for streaming due to its stability, adaptability, and compatibility with most streaming platforms. Despite its small latency, it offers several advantages:

• Consistent Quality: RTMP maintains a stable bitrate, ensuring smooth playback without sudden quality drops.
• Scalability: RTMP servers support large audiences, making them ideal for TV stations and businesses.
• Flexibility: Users can switch between live and on-demand content seamlessly.

Our RTMP Servers and Latency Management

At Hosting Marketers, our RTMP servers are optimized for efficient processing and minimal buffering, ensuring that latency remains at an industry-standard level while delivering high-quality, uninterrupted streaming. Our customers use RTMP to run TV stations, 24/7 streaming services, and event broadcasting, all of which perform flawlessly within the expected latency range.

Is Latency a Problem for Your Broadcast?

If you’re running a TV station, event streaming, or an on-demand broadcasting service, latency should not be a concern. The minor delay ensures stability and quality, making RTMP the best solution for most use cases.

For businesses needing ultra-low latency, alternative streaming protocols can be explored, but for most commercial and entertainment applications, RTMP remains the best and most reliable option.
