I was playing around with a Panasonic and Sony BR player at the electronics store and I have a small question I really want to have answered.

All my topics are neglected redhead-stepchild-style on this forum, so I won't even bother asking the Q until the BR-experienced poster identifies himself in this thread.

I don't consider myself an expert, per se, in the niche of Blu-Ray, though I do have my fair share of knowledge. I am, however, an expert in all things home theater I could probably find out very easily if I don't know it.

So fire away.

Alright.

At the store, there was a recorded demo playing on the BR player. I hit 'Open,' took the cartridge out of the machine, put it back in, and hit 'Play.' Well wouldn't you know it, the video demo resumed exactly at the point I took out the cart (as opposed to starting from the beginning or the menu screen).

What just happened? Do the BR players have a built-in HDD, and if they don't, how was it able to resume the demo with the cart/disc/thingy out of the machine?

Told you it was a small question.

Oh and thanks for answering.

Some DVD players (and obviously BR players based on this), do keep some information in memory as to where the video stream left off. You don't need an HDD for this; it's just a small amount of positioning information.

A limited example of this is the PS2, which can usually restart exactly where you left off if you hit stop while a DVD is playing.

Usually the positioning info is dumped from cache when you switch discs, but it seems sony has something smart enough to tell what disc is active before performing the dump.

I'm trying to understand the situation. You took the cartridge out, then put it back in, and it resumed at the point you ejected the cartridge orginally? OK, if that's the case, then yes, as CM said, it just saved the time code and resumed playback from there. Some DVD players have that automatic resume capability, and a lot have the ability to resume from where you left off, even if you power down the player. Hell, my Sony 550 from 1999 had that ability; sadly my newer Denon 2200 does not. You turn the power off and forget it. You have to read the disc from the beginning. The only thing I don't like about that player.

OK, I've never heard of disc players resuming the video after taking the disc out of it. On my DVD player I can hit Stop or put the unit on Standby, then hit Play and pick up exactly where I left off, but when I actually take the disc out it's all over. I guess the resume function is a high-end luxury..

Cool, that answers my Q. Thanks everybody
