QWhat is a Blu-ray disc?
AAs the most innovative home entertainment technology since the DVD and DVR, Blu-ray discs offer an unparalleled audio/visual experience. Blu-ray discs offer a significantly improved picture quality because they can contain more than five times the amount of data a standard DVD does.

QWhat is the quality of Blu-ray Disc video?
AWith a maximum resolution of up to 1920x1080p, Blu-ray discs offer a vastly superior viewing experience compared to other high definition or broadcast formats.

QWhat is 1080p and how does it differ from 1080i?
A"1080" means that each screen image or frame consists of 1080 horizontal lines, each with 1920 pixels across. Two methods of transferring these 1080 line high-definition frames exist at this size: 1080i (interlaced) and 1080p (progressive scan). Interlaced images follow the traditional method currently used in analog broadcast television where every other vertical line of information (or one-half the whole image) is transmitted to the television followed by the second half. Progressive scan images, on the other hand, display the whole image frame from top to bottom, thereby avoiding motion artifacts that can be problematic with interlacing schemes.

QWhat happened to HD-DVD?
AIn February 2008 Blu-ray “won” the technology battle over HD-DVD to become the preferred high definition content storage and player.

QWhat is the difference between a Blu-ray disc and a DVD?
ABlu-ray disc is a high-definition format and DVD is a standard-definition format. High definition video can contain up to 5 times more picture information than standard definition so Blu-ray disc uses a higher resolution blue laser to retrieve data from a Blu-ray format disc.

QCan Blu-ray Disc products play DVDs and CDs?
AYes, Blu-ray products will play DVDs, and most will play CDs.

QCan I play a Blu-ray disc on my DVD player?
ANo. Because DVDs use a red laser to read information, a DVD player will not be able to play Blu-ray discs.

QHow delicate is a Blu-ray disc compared to a DVD?
ABy using new hard coat technology, Blu-ray discs are more scratch and fingerprint resistant than DVDs. Their durable nature makes them a "family friendly" format.

QWhat equipment do I need to play a Blu-ray Disc?
AEnjoying everything Blu-ray disc has to offer right at home is as simple watching right on your Blu-ray equipped computer or connecting your television to your Blu-ray player or Blu-ray equipped computer with an HDMI cable.

QDo I need a new (HD) TV to view or record Blu-ray Discs?
ANo. Pre-recorded Blu-ray discs can be viewed on any standard definition TV set; even if the video was encoded in high definition. However, only an HDTV will provide the complete high definition Blu-ray disc experience.

QHow many channels of surround sound does Blu-ray disc support?
ABlu-ray discs can have 5.1, 6.1 or 7.1 channels of surround sound.

QWhat is HDMI?
AAn HDMI cable is a convenient way to carry multiple channel audio and high definition digital video signals from your Blu-ray player to your AV receiver, HDTV or HD projector using a single cable.

QIs there a recordable version of the Blu-ray Disc?
AYes. Recordable Blu-ray discs come in either write-once form (BD-R) or a rewritable form (BD-RE). The discs can be used in Blu-ray recordable hardware products including set-top recorders, PC writers and camcorders.

QCan a Blu-ray Disc recorder record to DVDs and CDs?
AAll Blu-ray discs recorders currently on the market allow for recording to DVDs and CDs as well as Blu-ray discs.

QWhat is the storage capacity of a Blu-ray disc? How much video will fit on a Blu-ray Disc?
AA single-layer Blu-ray disc holds up to 25 gigabytes, a double-layer up to 50 gigabytes. The amount of video that will fit on a Blu-ray disc depends on a number of factors, including the user’s bandwidth, the number of audio tracks and other user criteria.
