About the AVCHD format

What is the AVCHD format?
The AVCHD format is a high definition
digital video camera format used to record
a high definition (HD) signal 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.
As the AVCHD format uses a

compression coding technology, the
picture may be disturbed in scenes
where picture, field angles or brightness,
etc. change drastically, but this is not a
malfunction.
Recording and playback on your
camcorder
Based on the AVCHD format, your
camcorder records with the high definition
image quality (HD).
In addition to high definition image
quality (HD), your camcorder is capable
of recording a standard definition (STD)
signal in the conventional MPEG-2 format.


compliant device inserting memory card
into memory card adaptor, make sure the
memory card is inserted facing in the correct
direction. Note that improper use may cause a
malfunction.
On image data compatibility
Image data files recorded on memory card by

your camcorder conform to the "Design rule
