The iVDR is another promising technology that failed miserably in Japan and that will never see the daylight in any other country. For those of you who don’t know what it is, the iVDR is a concept and hardware system that uses cartridges (a bit like the first Nintendo’s) in which you have a 15 to 30GB HDD and these cartridges are compatible with a whole range of products like PC’s, camcorders, HiFi sets, video players, cars, … . There is also a mini version. The idea was good, but the absence of DRM might have scared some people away.
