A Quick Overview

Let's take a deeper dive into everything related to connectivity! ⚡️

When it comes to live-video broadcasts, it can be quite demanding on connections and require a faster speed than typically needed for other internet-based services (which can mean any issues can be pretty tricky to solve).

With that said, there are a few steps we can take to improve our connection and get better results. Let's jump into it now!

Performing the Test

Connectivity Test

For starters, you'll want to start by testing your current connection using the Connectivity Test shown in the Event Gateway/Settings area.

From the gateway, you'll want to select Run Test in the connectivity area to perform the test (it can take up to 30 seconds to complete).

Once you've run the test, you can select Show Details to expand the results:

Let's dive into what it all means!

Looking at the Results

Audio vs. Video

With Demio's connectivity test, we test both your audio and video connectivity and report the results for each.

The audio connectivity relates back to the connection quality you can expect for your microphone device, while the video connectivity relates to your webcam device.

Quality

The quality score is an overall score that summarizes the quality of your connection.

As long as there aren't any network-related connectivity issues (firewalls, network restrictions), this score will be determined by the two attributes that follow: Packet Loss and Bitrate

Packet Loss

In summary, packet loss simply refers to the amount of data you send our servers that have not been received. It can result from having an unstable connection that consistently goes in-and-out.

A high rate of packet loss is a primary culprit for when your audio/video streams cut in-and-out.

For Audio, a packet loss of < 0.5% is excellent and < 5% is good.

For Video, a packet loss of < 0.5% is excellent and < 3% is good.

Bitrate

On the other hand, bitrate refers to how fast your connection to our servers is (measured by how much data is being sent per second).

A low bitrate is a primary culprit for when your audio/video streams are poor quality/choppy.

For Audio, a bitrate of > 30 kbps is excellent and > 25 kbps is good.

For Video, a bitrate of > 600 kbps is excellent and > 250 kbps is good.

Best Practices

Reducing Packet Loss

When looking to lower our packet loss, the most important thing is to ensure that we're connecting over a stable network, especially since a live broadcast requires a constant connection.

Here are a few steps you can take to ensure the best results possible:

  1. Connect to your network with an ethernet cable (directly to your modem/router) rather than using wifi.
  2. Ensure the network you're on is working correctly. Spotty connections (constantly going in-and-out) can be an underlying problem related to the network itself. Check with your internet service provider to rule out any issues.

Improving Bitrate

When it comes to increasing the bitrate, your connection speed is the biggest factor.

Here are a few steps you can take to ensure the best results possible:

  1. Similar to reducing packet loss, try connecting via an ethernet cable. This will usually result in a faster connection to your network (in addition to being more stable).
  2. Ensure that you or others on the same network aren't consuming large amounts of bandwidth through other applications/uses (such as streaming video content, downloading large files, etc.). Doing so can limit the amount of bandwidth available for you to use for connecting to the Demio servers.
  3. Upgrade your internet service to a faster speed. Sometimes the bandwidth provided on your current internet plan may not be enough for broadcasting on a live video platform like Demio.

Other Tips

  1. If you have an older computer (or have several programs running at once), you might be limiting the available resources that Demio can use. Closing out any unused/competing applications can help free up resources.
  2. If you're using an older/poor quality webcam or microphone, this may be a limiting factor in the quality that you're able to broadcast.
  3. You may experience choppy audio/video when you initially turn on and connect your devices—this occurs as the connection is first being established and is normal. Once it successfully connects, everything should clear up.

There you have it—everything you need to know about connectivity when it comes to using Demio!
