Advantage Toshiba
HD DVD playback delivers outstanding resolution, bright, vivid colors
and stunning sound from the next generation DVD standard adopted by the
DVD forum
Backwards compatibility of standard DVDs allows you to enjoy your current collection of DVDs on the player
Video Up-conversion via the HDMI interface scales the standard DVD
video to output resolution of 720p or 1080i, matching the resolution of
the HDTV
Built in multi-channel decoders for Dolby Digital, Dolby Digital Plus,
Dolby TrueHD (2ch), DTS and DTS-HD will bring improved fidelity and
sonic realism to the soundtracks
Construction of the HD-XA1 was developed not only for advancements in
performance, but also for the refinements expected of a high
performance player. It features a motorized door which conceals the
disc drawer, function buttons and two front USB ports, for convenient
connection of gaming controllers. The HD-XA1 also includes three
different user selectable interfaces to further enhance customization
and a backlit remote control that is conveniently motion activated.
HD-XA1 adds insulated stabilizing feet to provide a steadfast foundation for the device.
Technology and Benefits
HD DVD Playback
High Definition video requires a tremendous amount of space on a disc,
thus a new Blue laser (versus a Red Laser for DVD) is utilized for HD
DVD. The blue laser, with it’s shorter wave length, allows for
information to be stored more densely on the disc, thus improving
storage capacity by about over 3 times compared to that of a red laser
technology. Additionally, more accurate and efficient video compression
like MPEG-4 AVC and VC-1 (based on Microsoft’s Window Media) compress
information to achieve file sizes that are less than half of the
current standard DVD’s MPEG2
High Performance Disc Drive
HD DVD not only provides a deliverable HD media format to the home, but
does so with the potential of greater performance than you have
experienced with HDTV. The HD-XA1 disc drive has an astounding
36.55Mbps transfer rate. To put that in perspective, standard DVD has
an average bit rate of less than 10Mbps and HDTV’s maximum rate is
24Mbps.
High Definition Multimedia Interface (HDMI)
HDMI is the first industry-supported all digital Audio/video connection
providing the transmission of uncompressed digital video and
multi-channel audio on a single cable. When matched with a compatible
HDTV, this single cable connection ensures that all signals remain in
their pure digital form. The HD-XA1 will output HD content through the
HDMI interface in the native format of the HD DVD disc content of
either 720p or 1080i
Backward Compatibility
Enjoy backwards compatibility and play your collection of standard
DVD’s on the player. In addition, via the HDMI interface, the standard
definition DVD picture resolution can be upconverted to near HD
quality, with output resolution of 720p or 1080i to match your HDTV’s
performance. Not only does this output the video in HD standard
resolutions, but because the conversion takes place in the player, the
signal remains free from excessive digital-to-analog conversion
artifacts.
Built-in Multi-Channel Decoders
The HD-XA1 has built-in processors to handle the multi-channel decoders
for Dolby Digital, Dolby Digital Plus, Dolby TrueHD (2 ch.), DTS and
DTS-HD. It employs the use of four DSPs to decode the multi-channel
streams of the wide array of audio formats. These 32-bit floating-point
DSP’s are world renown for their high accuracy and are employed in many
high quality audio solutions in the home theater market.
