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 discs will not play on current cd and dvd players, because they lack the blue-violet laser required to read them. The disc players (BDPs) are available from a number of manufacturers, including Panasonic, Pioneer, Samsung and Sony.

Sony led the fight for blu-ray dvd players. Sony is a rare company that may actually benefit from it’s success, mainly because higher production of the players could reduce component costs for the playStation 3, driving improved profitability for Sony’s all-important video-game unit. Also adding to the momentum was the gradual increase in sales of Sony’s playStation 3 home video-game console, which also works as a blu-ray player.

Blu-ray delivers crisp, clear high-definition pictures and sound, which are more detailed and vivid than existing video technology. Like the rewritable dvd formats, blu-ray uses phase change technology to enable repeated writing to the disc. It has has already won backing from major Hollywood studios, such as MGM Studios, Disney, and Buena Vista,as well as top technology firms like Dell, LG, Samsung and Phillips amongst others. But the absolutely genius part about Sony putting PS3 games on blu-ray disk (and they know this and planned it all along) means that the disk production ramped up very quickly to high volumes, thus softening the blow of the higher manufacturing costs of the new technology. Although the disc specification has been finalized, engineers continue working to advance the technology.

The next generation of dvds will hold high-definition video and sound. Likewise, consoles rely on single discs, so dvds that can hold six times more data mean much better,high-resolution games. Basically, blu-ray is a newer format of dvd with superior visual quality and storage space compared with standard dvds. While it is not compulsory for manufacturers, the Blu-ray Disc Association recommends that the disc drives should be capable of reading standard dvds for backward compatibility.

Entertainment decided to release movie discs only in the blu-ray format, joining Sony Pictures and Walt Disney Co. Blu-ray is the next-generation digital video disc. The next-generation dvd format blu-ray is winning more supporters than its rival, according to its backers. Just a few short weeks into 2008, blu-ray is now the dominant player in the game.
