Think of it as a way of getting HD.

There are many ways, like HDV, DVC Pro HD, AVCHD, and so on.

If you shoot using a HDV camera you will still get FULL HD.

Technically anything larger than standard TV format (simplified, in the US that's 720x 480) can be considered HD. (more info)

Consumers are usually confronted with two major resolutions:
1920x1080 (aka 1080i if footage is interlaced; 1080p if progressive)
and
1280 x 720 (almost always 720p - progressive)

However, there are many resolutions that can qualify as HD.

For example, if you look at a large number of TVs that are advertized as "High Definition" you'll notice that many are actually not displaying 1920x1080 but other resolutions.
That's still HD mind you.


One way of providing adult content via HD and still honor the fact that most consumers want immediate satisfaction is to provide the footage in different formats.
For example, I always published large resolution movies for download, and then another smaller version in Flash (with Flash Media Server, so everything played instantly without waiting).

Hope this helps a little
