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.

About GPS
The GPS (Global Positioning System) is a
system that calculates geographical location
from highly accurate US space satellites.
This system allows you to pinpoint your
exact location on the earth. The GPS
satellites are located in 6 orbits, 20,000 km
above the earth. The GPS system consists of
24 or more GPS satellites. A GPS receiver
receives radio signals from the satellites,
and calculates the current location of the
receiver based on the orbital information
(almanac data) and travel time of the
signals, etc.
Determining a location is called
“triangulating.” A GPS receiver can
determine the location’s latitude and
longitude by receiving signals from 3 or
more satellites.
As the positions of GPS satellites vary
constantly, it may take longer to determine
the location or the receiver may not be able to
determine the location at all, depending on the
location and time you use the camcorder.
“GPS” is a system for determining geographic
location by triangulating radio signals from
GPS satellites. Avoid using the camcorder
in places where radio signals are blocked or
reflected, such as a shadowy place surrounded
by buildings or trees, etc. Use the camcorder in
open sky environments.
You may not be able to record location
information at locations or in situations where
radio signals from the GPS satellites do not
reach the camcorder as follows.
In tunnels, indoors or under the shade of
buildings.
Between tall buildings or at narrow streets
surrounded by buildings.
