No matter the storage media is tape or CD-ROM and flash memory card, the final recorded HD file format is not uniform. The format is not compatible between each other. Then consumers would fall into confusion. AVCHD format appears to solve this problem.
Japan's Panasonic and Sony AVCHD is the joint launch of a new high-definition video format. It is based on MPEG-4 AVC/H.264 compression and encoding. H.264 is HD DVD and Blu-ray Disc format's compression technology. In addition to the AVCHD format only in user-generated video, AVCHD is to avoid the complex issue of copyright protection. For the new users of the digital camcorders, this format will not cause any problem on the transition of the formats.

The content can also be a 4G flash card to record 40-90 minutes of content. With the increasing capacity of flash memory card and continue to lower prices, a large-capacity memory card can record time of up to several hundred minutes.

Because the small size flash memory card than the CD a lot, so it is also reduced the size of the camera in a circle. Although the flash card market rival Sony and Panasonic are a respected memory stick, another respected SD card, in their own ways to launch its own AVCHD Memory Stick and SD cards using the AVCHD format digital camera camcorder. Other Japanese companies such as Canon and JVC and other manufacturers have introduced a variety of hard disk AVCHD format HD cameras and flash cards.

However, with the escalation of computer products will be resolved quickly. Some large-screen flat-panel TV through the USB interface or SD card slot of the machine can read and play the video in AVCHD format.
