About the AVCHD format

Your digital video camera recorder
incorporates both the AVCHD format and
the MPEG2 format for the recording
function.
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*
specification* , using efficient data
2
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, etc.
