Blu-ray Disc Alphabet Soup – Part Five IH-BD

RECAP

In previous posts, we explored the many different alphabetic designations that could apply to Blu-ray discs and the drives that could read, read and write to them.  We looked at BD-ROM, Combo Drives, BD-R and BD-RW, and looked at the many different types of erasable media (and drives) available.  We looked at single layer (25 GB) and double layer (50 GB) media, at write once and at erasable discs.

The last post looked at some of the proposed formats for the future, which expanded from single and double layer up to 4 layer (100 GB) and beyond — all the way up to 128 GB.  We looked at some of the uses of these larger (by 2010 standards) discs, and explained that this new standard may require new hardware to read and write to the new discs.   And we hinted at yet another proposed standard – the IH-BD disc.

Intro

In Part One of this series , I looked at some of the basic ‘Blu-ray’ drives that can be added to a computer or used as external drives.

Being able to watch a Blu-ray movie on your high resolution desktop or notebook computer is nice to have. In most cases, you’re sitting closer to the screen than you would be if you were playing the same video on a high-def television, and the fine items on the screen look even better. (You may lose the surround sound that a good home theater system can deliver if you use your computer, although it’s also possible to take advantage of the surround sound processing on many computers and feed the sound to multiple speakers arranged for surround sound.)

It’s a good thing, if your computer is short of slots, or you’ve run out of USB ports Read the rest of this entry »
