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*
1 or the 720p
specification* 2 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, hard disk drive, flash memory,
memory card, etc.
