ADSL Connection Video Broadcasting

Problem: When using Live Streaming solutions, live streams from some broadcasters have big frame loss, huge latency and sometimes don’t show at all.

Many home user internet connections are ADSL (Asymmetric Digital Subscriber Line), meaning they have low upload bitrate compared to download: In ADSL, Bandwidth and bitrate are said to be asymmetric, meaning greater toward the customer premises (downstream) than the reverse (upstream). Providers usually market ADSL as a service for consumers for Internet access for primarily downloading content from the Internet, but not serving content accessed by others.

This causes issues when trying to upload content like broadcasting live video. For live broadcasts, streaming bitrate is limited by broadcaster’s upload bitrate. Broadcasters with such connections will encounter severe issues (frame loss, long interruptions, big latency) if they try to live stream a stream with bitrate very close or greater than connection limit.

How to determine your connection type and limits (for adjusting streaming settings)? Measure Connection Speed
Do a speed test from broadcasting location to a location near streaming server (rtmp) using SpeedTest.net .
In example, drag and zoom to a server in North America and select it to test if you use our live demos or hosting plans .
Check upload bitrate. Divide by 8 to obtain transfer rate in bytes/second as bitrate is often displayed in bits/second.
Then adjust streaming settings so video, sound and interactions fit in upload bitrate (leave 10-25% margins).

If your site targets users from certain areas, browse some stats and identify common upload bitrate to adjust default streaming settings.

Compare 1000Mbps Dedicated Streaming Server Providers

Most important feature for a streaming server is connection (that limits number of simultaneous users that can be served at same time). While some providers clearly mention that, it can be estimated from available monthly bandwidth (in example 10TB limit requires an average of 30Mbps to be consumed so server is probably on 100Mbps connection).

Picked servers that provide 1000Mbps connection, over 20Tb/month and minimum specs of 1000Gb disk, WHM/Cpanel for easy web hosting management, located in North America.
