Will hardware be backward compatible to read today’s optical
media (CD-ROM, CD-R, DVD-ROM, DVD±R)?
HD: Yes, backward compatibility is established.
BD: Although the decision to support legacy formats is up to individual
manufacturers, every known prototype Blu-ray Disc product shown so far
has specified playback compatibility and, where appropriate, recording
compatibility with DVD formats. Some have also specified CD format
compatibility as well.
How are prices expected to compare with present DVD media and hardware?
BD: Each format group is comprised of many companies that manufacture
a very wide variety of products. The format groups themselves cannot
specify or even estimate specific prices for products. However, it’s
likely that next generation players and recorders will follow a similar
path as previous format products such as DVD players and recorders.
HD: We expect comparable prices with DVD hardware and media to be achieved
in the future.
