Is platform independence so hard? (Score 0)

From my viewpoint the issue isn't limited to downloading content to my TV, it is just downloading the content - to be played on whatever device I feel the need to play it on. Whether it's streaming video ported to my family room TV, or on my study's PC. The main issue to resolve (if possible) is portability of the data. This does not seem to be to the advantage of any one company, so none look to be attempting it. The legal issues of platform independence seem to be the key stumbling block. Do any DRM schemes translate from PC, to TV, to portable media player? will the media be archiveable?
