TOKYO — Matsushita Electric Industrial Co. Ltd., and Sony Corp. have jointly proposed specifications for high definition (HD) video cameras named the AVCHD format, which enables consumers to shoot and record HD video images using 8-cm DVD recordable discs. 
 
The AVCHD format is an HD digital video camera format for recording 1080i and 720p signals onto 8-cm DVD media.

MPEG-4 AVC/H.264 for video compression, and Dolby Digital (AC-3) for audio
 

The format employs MPEG-4 AVC/H.264 codec for video compression, and Dolby Digital (AC-3) or Linear PCM for audio codec. Data transfer rate is maximum 18 Mbits per second. The 8-cm DVD-RAM, DVD-RW, DVD-R and DVD+RW and DVD+R discs can be used.

While present DVD formats employ MPEG 2 video compression, the AVCHD format will use H.264 video compression to store HD images on an 8-cm DVD disk with 1.46 Gbyte capacity. It compresses data at twice the efficiency of conventional MPEG 2; a one-sided DVD disc can store 20 minutes of high-resolution digital images while a two sided disc can store 40 minutes of footage at a 9 Mbps data rate.
