Avchd Format - Sony α NEX-3N Instruction & Operation Manual

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
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.
Discs recorded with HD (high definition) image quality can be played back only on
AVCHD format-compatible devices. DVD-based players or recorders cannot play back
HD image quality discs, as they are incompatible with the AVCHD format. Also, DVD-
based players or recorders may fail to eject HD image quality discs.
