Forward Versatile Disc: Difference between revisions

FVD or Forward Versatile Disc is a offshoot of DVD developed in Taiwan jointly by the Advanced Optical Storage Research Alliance (AOSRA) and the Industrial Technology Research Institute (ITRI) as a more inexpensive alternative for high definition content. The disc is similar in structure to a DVD in that pit length is the same and a red laser is used to read it, but the track width has been shortened slightly to allow the disc to have 5.4GB of storage per layer as opposed to 4.7GB for DVD. The spec allows for up to three layers for total of 15GB in storage. WMV9 is used as the video codec allowing for 135 mins. of 720p video on a 2 layer disc and 135 min. of 1080i video on a 3 layer disc. FVD uses AAES copy protection which is the one of the same schemes used in both HD-DVD and Blu-ray discs. FVD is not expected to be marketed outside of Taiwan.
