AVCHD format
The AVCHD format was developed for high-definition digital video cameras when recording
an HD (High-Definition) signal using high-efficiency compression coding technology. The
MPEG-4 AVC/H.264 format is used 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 compression coding technology, the picture may be unstable
in scenes where the screen, angle of view, or brightness, etc. change drastically, but this
is not a malfunction.
