whether from CD or DVD sources. In other machines, the audio clock is
slaved to the video – not to the audio data. This is done to keep audio syn-
chronized with video. In the PMDT, the audio is optimized, independent of
the video, while maintaining proper synchronization. The PMDT even lets you
delay audio to compensate for recordings where the video is not synchronized
with the audio. This same feature can correct for systems where video proces-
sors delay the video signal by such a degree that the audio is no longer in
sync.
Digital audio outputs are provided on four different connector standards: EIAJ
(Toslink), S/PDIF on RCA and BNC, and AES/EBU on XLR.
Unexcelled video techniques Many people think good video performance is a given when it comes to DVD.
While it’s true that even the most basic DVD players deliver much higher per-
formance than VHS tape, many fall short of the full potential of the format.
The PMDT is designed to extract video information from the disc with the
greatest fidelity, preserving the digital signal, converting to analog and buffer-
ing the analog output with the greatest care. The PMDT achieves superior
video performance through attention to detail. Careful selection of parts and
construction details – such as trimming circuit elements by hand – allow us to
achieve better results. This is the same approach that distinguishes our audio
designs and contributes to both their cost and their value.
The PMDT uses a 5-part-per-million TCXO (temperature-controlled crystal os-
cillator – the same type used for our digital audio) to ensure low-jitter recov-
ery of the digital video signal.
The PMDT uses 10-bit, oversampled video DACs (rather than the standard 8-
bit variety) for highest resolution. An active I-V (current-to-voltage) converter,
phase-accurate analog filters and broadcast-quality analog output buffers com-
bine to form a system where all aspects of the video path are well balanced.
Analog video outputs include composite on RCA and BNC, S-Video, and Com-
ponent (BNC). The optional PVP cards provide a 480p (y, pb, pr) output and
video processing for additional video inputs.
Ease of use For all of the advantages that DVD can bring to audio and video performance,
the frustrating difficulty of the format has been its user interface. DVD players
tend to be difficult and awkward to use – and no two seem to work the same
way. The operation of most players even varies from disc to disc, complicating
the operation of an otherwise familiar player.
The PMDT makes significant progress in this area. It allows the setting of sys-
tem defaults to help automate basic selections such as language, surround for-
mat and aspect ratio. System defaults are easily overridden for individual discs
with different, preferred settings. What’s more, the PMDT can automatically
recall the settings of a DVD from the last time it was used – with no additional
programming required.
People around the world are listening to DVDs with Dolby Pro Logic ® because
they don’t know that they need to select Dolby Digital, sometimes for their
player, sometimes for each disc they play, sometimes each time they play it.
