What is a Blu-ray disc?
Also known as BD, Blu-ray discs are the latest development in optical media disc storage. A Blu-ray disc can have a capacity of 25GB (single-layer disc) or 50GB (dual-layer disc), meaning that it can hold over five times more data than a DVD. The Blu-ray disc can be used to store High Definition films, as well as bonus materials and interactive features. For more information please visit www.wewow.co.uk/blu_ray_replication.asp 7. What is the difference between PAL and NTSC PAL stands for Phase Alternating Line and refers to the television broadcasting standard which is used by most of Europe, amongst other countries. NTSC is an alternative television format which is used for broadcasting in United States, Canada, Japan, as well as some parts of Central and South America. When producing a DVD, it is important to recognise which area of the world your DVDs will be played in so that your master can be produced in the correct format.
