Aspect Ratio
The width of a TV screen relative to its height.
Conventional TVs are 4:3 (in other words, the TV screen

AVCHD is a new format for high definition video
camcorders which can record and play high-resolution
HD images.
Blu-ray Disc™
Blu-ray Disc™ is a next generation optical video disc
which is capable of storing much more data than a
conventional DVD. The large capacity makes it possible
to benefit from the features such as high-definition
videos, multi-channel surround sounds, interactive
menus and so on.
Just as a book is split up into several chapters, a Title
on a BD-video or DVD-video is usually divided into
chapters. See also "Title".
