What is Blu-ray?
A7. Blu-ray, also known as Blu-ray Disc (BD), is the name of a next-generation optical disc format jointly developed by the Blu-ray Disc Association (BDA), a group of the world’s leading consumer electronics, personal computer and media manufacturers (including Apple, Dell, Hitachi, HP, JVC, LG, Mitsubishi, Panasonic, Pioneer, Philips, Samsung, Sharp, Sony, TDK and Thomson). The format was developed to enable recording, rewriting and playback of high-definition video (HD), as well as storing large amounts of data. The format offers more than five times the storage capacity of traditional DVDs and can hold up to 25GB on a single-layer disc and 50GB on a dual-layer disc. This extra capacity combined with the use of advanced video and audio codecs will offer consumers an unprecedented HD experience.
Blu-ray is the other main format now available for HD. Each disc, the same size as a regular DVD, can produce a progressive video image resolution of up to 1920 x 1080 (known as 1080p) for truly stunning visuals. Blu-ray also offers a significantly higher data transfer rate than television HD broadcasts for an improved picture presentation.Currently Blu-ray can store 25GB of data on a single layer which means that dual layer discs can harbour a potential 50GB of HD content. Regular dual layer DVD is only able to present 9GB of SD content.
