Named "Together", the system is built on top of BBC's Standard Media Player and works with any video or audio BBC content, including BBC iPlayer, BBC Sound, Bitesize, BBC News, and BBC Sport.
The developers behind the tool say it will enable users to sync much more accurately than trying to press the play button at the same time. "In fact, sync'd playback through BBC Together should be close enough to have a video or voice call at the same time and react to the big reveals in a drama, or enjoy the punchlines in comedy programmes together," they said in a blog post.
To use the service, users will need to copy-paste a BBC link into the BBC Together page to create a link to a group session that other participants can join. Only the user who created the group session can play, pause, rewind, and fast-forward the video.
The tool is designed to keep people "together even when they are physically apart" during the coroanvirus lockdowns. The BBC has seen viewership soar since the virus pandemic hit the UK, with May 10 being iPlayer's biggest day ever.
