Maintenance and
precautions
What is the AVCHD format?
The AVCHD format is a high definition
digital video camera format used to record
a high definition (HD) Signal of either
the 1080i specification*l or the
nop
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, "Memory Stick PRO Duo"
media, etc.
