About the AVCHD format
What is the AVCHD format?
The AVCHD format is a high definition
digital video camera format used to
record an HD (high definition) signal
of either the 1080i specification* 1 or the
720p specification* 2 , 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 video signal shot on
a digital video camera recorder to be
recorded on 8 cm DVD discs, internal hard
disk drive, flash memory, “Memory Stick
PRO Duo,” etc.

camcorder records with the HD (high
