DVD VIDEO A disc that contains up to 8 hours of moving pictures even though its diameter is the same as a CD. The data capacity of a single-layer and singlesided DVD is 4.7 GB (Giga Byte), which is 7 times that of a CD. The data capacity of a double-layer and single-sided DVD is 8.5 GB, a single-layer and double-sided DVD is 9.4 GB, and double-layer and double-sided DVD is 17 GB. The picture data uses the MPEG 2 format, one of the worldwide standards of digital compression technology. The picture data is compressed to about 1/40 (average) of its original size. The DVD also uses a variable rate coding technology that changes the data to be allocated according to the status of the picture. Audio information is recorded in a multi-channel format, such as Dolby Digital, allowing you to enjoy a more real audio presence. Furthermore, various advanced functions such as the multi-angle, multilingual, and Parental Control functions are provided with the DVD.

JPEG (Joint Photographic Expert Group) Under the auspices of the International Organization for Standardization (ISO), JPEG is defined as a universal standard format for digital compression and decompression of still images for use in computer related systems. Usually, the compression rate is variable before visible degradation occurs. Still images are compressed about 1/10 to 1/100 original size. Title The longest section of a picture or music feature on a DVD, movie, etc., in video software, or the entire album in audio software.
