How fast does my internet connection need to be?

We recommend an internet connection fast enough to allow 3.2Mbps (megabits) playback, or 5Mbps playback for our best HD quality. If you’re having buffering issues while streaming but think you have a fast enough connection, you should contact your internet service provider.

You could also try switching to SD (Standard Definition).

What's the difference between High Definition and Standard Definition?

To be classed as 'true'Ìýhigh definition, we encode in at least 1280x720 resolution or 720p. Many smart TVs have the capability to stream at 1080p. We use h.264 with a bitrate of 3.2Mbps (going up to 5Mbps for best quality, should your connection allow) and 128kbps audio. This means that streaming programmes in HD quality will put demands on your network connection.

Standard Definition is any resolution which streams at lower than 720p. SD programmes usually require less bandwidth to stream and download and won't put as much demand on your network connection as HD programmes.

Is 5.1 surround sound available on iPlayer?

Currently, iPlayer only supports stereo sound. However, we continue to explore ways of improving the audio experience to our users.

Can I watch in HD on an older computer?

Some older computers may struggle to handle HD playback. To avoid lots of buffering during playback we recommend a modern computer with a graphics card and processor that can handle the graphics. You'll need to watch in full-screen mode to reduce the demand on your computer.
