Between Blu-Ray and DVD, it seems there is no difference in appearance because they look similar. But if you want to know the difference for the first time easily is that in their storage capacity. When we compare the 4.37 GB DVD (8.74 GB in case of Dual Layer DVDs) with Blu-Ray, Blu-Ray has greater capacity which has 25 GB (50 GB in the case of Blu-Ray Dual Layer).
While others, to see the video of Blu-ray, commonly abbreviated as BDMV (Blu-Ray Disc Movie), you need a Blu-Ray HD High Definition TV and should use Full HD (1080p) to get the spectacle of a clear and definitely sharper. And if you want to read the Blu Ray of the reader, a Blu-Ray must support a PC/computer writer. One of the consoles that has long read Blu-Ray is the Playstation 3.
Blu-Ray has higher capacity, about 25/50 GB, enabling storage and vision of high definition movies, from the famous 1920×1080 (Full HD), compared with a DVD that only has the definition movies at 720×576. Another thing that it supports the format of 1440×1080 (VC1 codec only), 1280×720 (HD Ready) and 720 long×576 (including 720 × 480). It also affects the sound quality is a further advantage that you get, because it can be up to 7.1 channels in HD quality and in some cases as a lossless (no loss of quality).
Quality data that is supported by the Blu-Ray is in fact 48 Megabits per second, compared with a DVD that is only around 8 Megabits per second. There are also a few demos and movie trailers on the BR official website at Blu-RayDisc.com.
Plus, the codec used by Blu-Ray is H.264, much better than the old mpeg2 DVD, and this is also contributed to the image brighter and with fewer artifacts.
