o It provides Superior Image Analysis What
gives Blu-ray a significant step ahead ofDVDis the higher resolution ability it has
which consequently can give the viewer an
image with more detail.
o Apart from the higher resolution Blu-ray also
utilizes different video-compression methods
meaning that it can give you higher contrastand fuller colors.

Development

16/20
What changes and improvement have been made to the
inventation
Blue ray have a bigger storage capacity thannormal DVD. A single layer of Blue ray can holdabout 25GB of data while normal DVD only canhold 4.7GB of data in one layer.
If we use the same amount of storage capacity butthe video we can fit into the Blue ray and normalDVD is different. For example, if we use 50GB of
storage capacity of each type of disk, Blue rayneed to use 9-hours to fit in high-definition(HD) into
50GB while the normal DVD need about 23-hours tofit the standard definition(SD) into 50GB.
The Blue ray will not easily face jamming problemcompared to the normal DVD.

How might it be improved in the future
To ensure that the Blue-ray Disc format is
easily extendable (future-proof) it also
includes support for multi-layer discs, whichshould allow the storage capacity to be
increased to 100GB-200GB (25GB per layer)
in the future simply by adding more layers to
the discs.
