Blu-ray Adds Microsoft’s VC-1 Codec

The Blu-ray Disc Association and Microsoft have agreed to include the VC-1 advanced compression video codec, the proposed SMPTE standard based on Windows Media 9, as a mandatory codec in Blu-ray Disc’s BD-ROM specification for video playback equipment.

Video codecs are used to compress video images for storage to a disc and then decompress them for viewing.

A critical piece to Blu-ray Disc was making sure that any advanced compression codecs included in the specification accomplish the compression and decompression with little or no visible loss of image quality.

Blu-ray Disc is an optical disc format being developed for high-definition video and high-capacity software applications.

A single-layer Blu-ray Disc will hold up to 25 gigabytes of data and a double-layer Blu-ray Disc will hold up to 50 gigabytes of data.

“We’ve been committed to adding advanced codecs to enrich the Blu-ray Disc format,” said Blu-ray Disc spokesperson Maureen Weber, general manager of HP’s Optical Storage Solutions Business.

“We want to offer content providers a variety of compression codecs to suit their various needs. With the addition of Microsoft’s VC-1, we extend that option in a package that makes Blu-ray Disc’s capacity advantage even more substantial while still delivering the picture quality that consumers demand from high-definition technology.”
