Blu-ray is a new optical disc standard based on the use of a blue laser rather than the red laser of dvd players. It is not just a format for high-definition video and audio, it's a higher-capacity disc format. This format is currently supported by more than 180 of the world's leading consumer electronics, personal computer, recording media, video game and music companies.
Blu-ray players capable of showing picture-in-picture - a feature called "bonus view" - have only just started to appear.

The disc players (BDPs) are available from a number of manufacturers, including Panasonic, Pioneer, Samsung and Sony.
