[mythtv-users] OT: 16:9 vs 4:3 signals

[David Farber]

Sorry for the off-topic post, but I expect that someone on this list has the technical knowledge to answer this question.

How is the aspect ratio of a video signal negotiated between two video devices?  For example, let's say I have a DVD player capable of 480p output.  Am I correct is assuming that I would get a larger, higher resolution picture if I plugged this dvd player into a 17-inch 16:9 480p-capable tv/monitor than if I plugged the same dvd player into a 17-inh 4:3 4800-capable tv-monitor?

Can the dvd player detect the presence of a 16:9 tv versus a 4:3 tv?  Or is the 16:9 tv set scaling the 4:3 picture?

Thanks for the info,
david
