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*
1
or the 720p
specification*
2
on internal hard disk drive,
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, etc.
