HDMI’s integrated High-bandwidth
Digital Content Protection (HDCP) copyright protection technology supports
secure one-way transfer of digital content between a source, such as D-VHS, and
STBs, projectors, monitors and digital TVs (DTVs). HDMI plays back high definition
D-Theater (see “About D-Theater”) software, prerecorded high definition
material available from five Hollywood studios
and other providers, and even standard definition analog tapes. It transfers
analog and S-VHS signals after conversion to 480p (progressive) digital video
for greatly improved image quality.
Moreover, since a single HDMI cable carries all video and
audio signals, it is easier to set up and enjoy today’s most advanced home
theater performance than it is to set up a conventional system. HDMI makes ugly tangles of cables a
thing of the past.

What sets D-VHS apart from other digital systems is that it
is the only format that can record HDTV in full quality and without further
compression or decoding and re-encoding stages. Because D-VHS’s 28.2 Mbps HS mode far
exceeds the 19Mbps specification of ATSC MPEG-2 HD broadcasting formats, and
because a single DF-480 D-VHS cassette stores up to 50 gigabytes of data, D-VHS
records high-definition sources such as 1080i or 720p digital broadcasts
complete with 5.1-channel surround sound.
Of course, D-VHS also records standard definition (SD) sources such as
480p* and 480i digital broadcasts thanks to its 14.1 Mbps STD and other LS
modes. There’s even a built-in
MPEG-2 encoder to easily make high-quality digital recordings from analog NTSC
sources in the high quality HS**, STD, or extended-time LS3 modes.
