What is the AVCHD format?
The AVCHD format is a high-definition digital video camera format used to record SD (standard
definition) or HD (high definition) signals of either the I080i specification* or the
nop
specification**
on DVDs, 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 A VC/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 (HD) video signal shot on a digital video camera recorder to be recorded on DVD discs, in
the same way as it would be for a standard definition (SD) television signal.
*
