The stream from this program will be your “High bitrate” broadcast, so you’ll need to set a relatively high bitrate-somewhere around 6 Mb/s or 4 Mb/s at 1080px. With Pearl and Pearl-2, this process is quite simple.įirst, you’ll need to configure your channel’s layout to your liking by adding sources, backgrounds, images etc.
#USING ABR VIEWER HOW TO#
If your chosen CDN uses multi-bitrate over adaptive bitrate, you’re probably wondering how to configure your encoder to send multiple streams of the same program.
With MBR, you need to configure and encode multiple streams of your program at different bitrates and broadcast to your chosen CDN.Ĭonfiguring your encoder for MBR: a brief How-to While adaptive bitrate automatically transcodes a single stream received from your encoder, multi-bitrate works a bit differently. Making such a high-quality stream available allows those viewers with the most bandwidth freedom to view your stream at its best possible quality while also simultaneously catering to lower-bandwidth viewers by automatically transcoding the stream to a level that matches the limits of their network. high-bitrate and high-resolution) stream you’re able to upload based on your uplink bandwidth. What does this mean for the encoder administrator? When broadcasting to a CDN that uses ABR, you’ll want to configure the highest-quality (i.e. Selecting this option enables ABR, ensuring any restrictions or unexpected congestion on the viewer’s network does not hinder the stream from playing. The ABR “Auto” option in your CDN’s media player.Ī CDN like YouTube would display an “Auto” option for viewers within a video’s viewing options. A graph showing how ABR transcodes your stream depending on the viewer’s bandwidth.įigure 2. In this way, ABR automatically “course corrects” your broadcast to ensure the viewer is able to continuously view your content without hitting a buffering wall. The CDN detects the bandwidth availability of each connected viewer and automatically transcodes the broadcast into a new stream with bitrate that is appropriate for each user’s respective network. With ABR, you send a single configured stream to the CDN. Adaptive bitrateĪBR is the more common of the two methods, used by many popular CDNs such as YouTube. Some CDNs use ABR and some use MBR-understanding the difference between these terms allows you to configure your encoder accordingly and ensure your chosen CDN can distribute your streamed content to viewers of all levels of bandwidth. If you’re familiar with the basics of configuring live streams, you may have heard the terms multi-bitrate (MBR) and adaptive bitrate (ABR).ĭistinct terms that are often used interchangeably, MBR and ABR are concepts that relate to how CDNs make your content available for viewers.
