Video Sync Across All TVs

[theGeek 4]

I may be a lone in this request but I have 3 HTPCs running media browser in my house.

 

It would be awesome to be able to play and sync a video across all HTPCs.

 

Like SONOS but for video.

 

Am I alone?

No and it is something we are looking into.  Implementing something like this across heterogeneous systems would be very tricky but, if anyone can figure it out, it is the folks on this team.

One thing I will suggest on this is Apple's genius move:

 

When implementing Airplay, they specified an on-device buffer time of about 2 seconds

They then send sync and volume change as tiny async network requests

Then each device can 'jump' and 'nudge' to the exact playback ms in it's own buffer without having to refill.

In Emby, this could be after the transcode so that the video going out to each device is no longer CPU intensive for the server when latency is calculated.

 

One could even use NTP's method for determining latency offsets for each device

 

 

 

For Video playback a large buffer is a perfectly acceptable tradeoff as you're not concerned whether your video starts as quickly as possible, and much more impressed that it's in sync across all devices.

Thanks for the feedback.
