PKI Dvd Player - on a stick

For downloadable movies

USB devices vary a lot. You can plug in a phone, a memory stick or a DVD player. So imagine a DVD player that looks like a memory stick. To the computer it is a DVD player.

So that is what the user sees, but a USB device can do a lot more like have multiple interfaces. So suppose we add an interface that accepts downloading content from movie providers ?

Since the USB stick is self-contained it could ensure only legit movie content is downloaded and could expire anything downloaded after a preset time. You can't see what's on the raw memory, its only a DVD drive (or multiple DVD drives) to the user except when using software to download.

In copy protection (and PKI) terms, just having a bit of hardware made by movie providers means they have control. This DVD player stick can be reprogrammed with other downloaded movies instead of having to take plastic discs back to the rental shop.

DVD player on a stick, its like having a little Blockbuster in your own home.

Couple that with TCP/IP broadcast protocol and you get dirt cheap movie rentals and real tv on demand without flooring your neighbourhood's internet connection.

       Some Linux ditros do almost the same, except the copy protect part (not my bone).

       Weird this idea got an immediate fishbone and few annos, its actually a reasonable idea.   

       Let me elaborate a little -   

       1) Online film services typically offer a very poor selection or are overpriced.   

       2) The DVD/BD distribution chains are already trusted as a viable way of getting new content to subscribers. DVD rental companies are trusted.   

       3) The reason for 2) is that DVD players make it difficult for users to cut and paste content onto the internet. DVD player manufacturers are trusted.   

       So imagine a solid state DVD player made by Sony, on a stick. Its still a real trusted DVD player made by Sony. And because it behaves like a regular DVD player it is equally hard to copy content.   

       All the stick needs extra is an encrypted interface to get the stuff onto it from trusted online content providers, maybe the movie companies themselves. This can be done with PKI stuff.   

       When putting loads of stuff on the DVD stick, there would need to be an user interface to choose / mount / unmount a DVD - thats it.   

       The end result is a way to use the existing DVD rental trust networks to provide an online service. This may result in a cheap online service with a good selection of recent content and a good price.   

       //Movix// //HDMI drive// As per above comments, these are just regular software solutions and don't offer any kind of copy protect, especially the DVD disc kind which movie companies are so stuck too.

       I should have look closer to the PKI part (it's the first word in the title, my bad). Seems to me that this concept should work.   

       At some point, the companies will must take the network paths for distributing their content. But I suspect that the fear to unwanted copies will keep them in the old well known system of physical supports until it doesn't work anymore [+].

       I can't really see the distinction between this idea and the 'HDMI drive'. The HDMI drive could easily have AACS (the standard PKI for video); the movie would be stored in its encrypted form (bit-for-bit identical to the data on a Blu-ray) and decoded for output through the HDMI cable.   

       Your idea is a bit confusing. It is not clear if the device has USB output or typical AV/HDMI output.   

       If it is does have a USB output I'm not sure how the PKI encryption would have any useful effect, since the only file types playable by TV and DVD through the USB input (that I know of) are regular AVI, MPEG etc. which could easily be ripped straight from the device.

       [xaviergisz] Its a USB DVD Player so all you can copy are the encrypted forms.
