Additional Information
About playback of discs recorded in
AVCHD format
This player can play AVCHD format discs.
What is the AVCHD format?
The AVCHD format is a high-definition digital
video camera format used to record SD (standard
definition) or HD (high definition) signals of either
the 1080i specification
*1
or the 720p
specification
*2
on DVDs, using efficient data
compression coding technology. The MPEG-4
AVC/H.264 format is adopted to compress video
data, and the Dolby Digital or Linear PCM system
is used to compress audio data. The MPEG-4 AVC/
H.264 format is capable of compressing images at
higher efficiency than that of the conventional
image compressing format. The MPEG-4 AVC/
H.264 format enables a high definition (HD) video
signal shot on a digital video camera recorder to be
recorded on DVD discs, in the same way as it would
be for a standard definition (SD) television signal.
*1
A high-definition specification which utilizes
1080 effective scanning lines and the interlace
system.
*2
A high-definition specification which utilizes
720 effective scanning lines and the progressive
system.

Some AVCHD format discs may not play,
