Why is content from cable/satellite TV always in sync on multiple TVs, but two iPads with the same stream are pretty much out of sync?
In: Technology
Internet protocol for broadcast (what the iPads are using) isn’t deterministic…the time and route that data packets takes isn’t guaranteed, stable, or generally predictable. So two iPads, even watching the same stream, are going to get data at different times and get out of sync.
Broadcast media like cable or satellite is one signal…everyone gets it at the same time. The only difference is the processing time on the device but that’s so small that you can’t notice it.
