An ISO file, often called an ISO image, is a disk image of an ISO 9660 file system, which is also in fact an "image" of an entire CD or DVD. The entire contents of a disc can be perfectly represented in a single ISO file.

You can think of an ISO file like a box that holds all the parts to something that needs built - like a child's toy you might buy that requires assembly. An ISO file is the same way. The file itself is no good unless it can be opened, assembled, and used. The most common way to make use of an ISO file is to burn the ISO file to a CD or DVD. It's a different process than burning an MP3 file or a document to a disc because your CD/DVD burning software must "assemble" the contents of the ISO file onto the disc.
And if there are some ISO image about some Movies, how to open them or share them on TV?
