Technology / How does my DVD player remember where I stopped the DVD earlier?
« on: 28/11/2009 14:11:10 »
We have a DVD player. Occasionally we do not finish a movie and take out the disk. Other DVDs are watched before we reinsert the DVD that was not finished. Our DVD player seems to remember where we left off a long time before and goes right back to that place on the DVD to continue. Quite handy, however, I do not understand how the DVD player does this. First of all, it does not do this always. Secondly, it seems to be able to do even if it is completely disconnected from the power. Thirdly, it does not seem to matter if one or several other DVDs are played in the meantime.
How does this work?
