Digital VHS (D-VHS) was a videocassette format that transmitted MPEG transport stream via magnetic tape. The medium was notable for having introduced high-definition video into the consumer VHS market. It was capable of storing up to four hours of high-definition video, and could scan a maximum of 1080 interlaced lines per frame.
D-VHS was a combined effort between JVC, Phillips, Hitachi, Matsushita and Sony, which culminated in a high-definition videocassette intended for mass consumption in the late 1990s. Mitsubishi also collaborated on developing the format, but experienced compatibility issues that were never resolved.
Several major studios (Artisan, Dreamworks SKG, 20th Century FOX and Universal) supported the D-VHS format, including a broadcast platform for it called D-Theater. However due to overwhelming competition from digital formats such as DVD, the D-VHS medium was discontinued.
