Blu-ray replication is a technical manufacturing process considered for ROMs. This process seems only reasonable as a means for manufacturing many DVDs, say more than 2,000 units. Blu-ray is the leading standard for HD (High-Definition) delivery as well as publishing that allows you to offer your video, audio as well as images that will look as clear and stunning as they did in the studio back then.
In fact, it’s been in tough competition with HD-DVD. The former offers full HD at 1920*1080p. Not only that, it also offers frame rates of 24 or 29.97 frames per second (of course depending on your actual content). Sometimes referred to as BD, it can store a lot more than HD-DVD.
