</div>I think people are underestimating the degree of precision required<br>
for a whole house jukebox type scenario.<br>
<br>
If you're watching your neighbor's PPV, you wouldn't have had any way<br>
of knowing if you were seeing it 500ms ahead or behind him. If you<br>
want a whole-house jukebox, 500ms is an eternity.<br><br></blockquote><div><br>500ms is not an eternity, if the rooms are far enough apart not to get the 'echo' effect that has been mentioned.<br><br>A couple weeks ago I had the Pats game on my main tv (remote FE) while cleaning my house. I wanted to have it playing in all the rooms so I could watch the game while cleaning. I hit the record button my my box to put it into the recorded programs. I then played the recording from the bedroom FE and the kitchen FE. The kitchen FE is 11g wireless so it's the most laggy, so I used that as patient zero - I turned the volume up loud enough to hear from the other rooms, and then paused the other rooms till they caught up. I only did this one time. I then returned the kitchen box to normal volume and left all three boxes on for the remainder of the game.<br>
<br>After 2 hours the kitchen machine was quite a bit behind but it also froze up repeatedly due to the underpowered stream. But the point of this story is, even though the TVs weren't perfectly in sync, they were close enough where it wasn't a big deal as I moved room to room. I'm perfectly fine with a 500ms lag if it means I can push one stream to all my boxes.<br>
<br>Hey, speaking of that, how do individual STBs do it? I can watch the same show on 2 different cable boxes and those are perfectly in sync.<br></div></div>
