Did you know that there is a standard to synchronize time sensitive media across devices? It’s a draft. It’s not implemented in any browser. But luckily that’s not a huge problem. You can still use it today. The Timing Object specification is a W3C draft proposed by the Multi-Device Timing Community Group. The work on the spec started over 7 years ago. Sadly it went largely unnoticed. At that time there was not much interest in precisely synchronizing media in the same tab or across devices. But today features like Apple’s SharePlay or BBC’s Together are well known and heavily used. The TimingObject (which is the core piece of the Timing Object specification) is what makes it easy to implement the same functionality on any website. A TimingObject is very flexible and cannot only be used to synchronize media. You can synchronize anything that fits on a timeline. That could be timed advertisement, synchronized stats for a sports broadcast, subtitles, or a second screen app that shows relevant information which matches exactly what is shown on the main screen.
