Table of Contents Maintenance and precautions About the AVCHD format What is the AVCHD format? The AVCHD format is a high definition digital video camera format used to record a high definition (HD) signal 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.  As the AVCHD format uses a compression coding technology, the picture may be disturbed in scenes where picture, field angles or brightness, etc. change drastically, but this is not a malfunction. Recording and playback on your camcorder Based on the AVCHD format, your camcorder records with the high definition image quality (HD). In addition to high definition image quality (HD), your camcorder is capable of recording a standard definition (STD) signal in the conventional MPEG-2 format.  Damaged or lost data may occur in the following cases (the data will not be compensated for):  If you eject the memory card, or turn off your camcorder while your camcorder is reading or writing image files on the memory card (while the access lamp is lit or flashing)  If you use the memory card near magnets or magnetic fields  It is recommended that you make a back-up of important data on the hard disk of a computer.  Do not attach a label or the like on memory card or memory card adaptor.  Do not touch, or allow metallic objects to come into contact with the terminals.  Do not bend, drop or apply strong force to the memory card.  Do not disassemble or modify the memory card.  Do not let the memory card get wet.  Keep the memory card out of the reach of small children.
