Hello,
i want to build a DRM device using microcontroller / something similar.
the idea in general is to hook from one side usb and the outher side to screen using hdmi , and the device in the middle will varified the usb
and play is encrypted content on the screen.
my q. is:
A. Witch is the best way to go to achieve this goal? (best way = cheaper, most quality output, easier to make)
B. How do i program this kind of stuff on the microcontroller? are there any libererys to help with such a project?
C. Are anyone know any guide/tutorial about such a projects? i'm experienced at low level programming (c, drivers) but never did anything with microcontrollers before...

p.s.
i considered to use raspberry pi / something like this for this project but it's too expensive and too slow , i want something that will boot up in seconds and will work smoothly and coast around 10$ , i know i ask a lot ... thank you for the help!!!
 
it's a project , i have no need of actual media player.
i want to understand how this work and to build one.
 
In which case use a Raspberry Pi, or something similar - building and programming one from scratch would be an immense job.

Assuming you really want to?, do it on a PC first, bearing in mind not to use libraries or routines you download, you need to write it entirely from scratch so as to understand how to implement it on a much smaller and slower system.

You claim the PI is too expensive and too slow?, so you're going to have to make hardware that's a lot more powerful than the PI, and is going to cost a lot more.

Here's an example of a commercial unit, you'll probably struggle to make something a fraction as good and spend many times the price.

can you please suggest me on a good micro controller/ board that will be good for my purpose?

You don't want a micro-controller, you need a full micro-processor, with lot's of RAM and support chips etc.

I've no idea what it would take to meet your requirements, as a PI is pretty high spec for an amazingly low price.
 
Nigel, Went to this site you suggested:

Slick rig and an excellent example for the OP.

I did, however, notice this Amazon shipping restriction: "This item does not ship to the United States" with a "learn more" button, which I hit.

I read through it and almost fell out of my seat with this specific restriction under "International Delivery Restrictions":

"Light bulbs can't be delivered to the Republic of Ireland."

I'm not even going to ask...

Possibly it means 'incandescent' light bulbs can't be delivered there?, presumably they are banned and you should be using LED ones (or CCFL).

I don't think you can buy normal '60W' whatever bulbs in the UK any more?, but you can still buy specialist bulbs, as used in flame effect fires etc.

However, as it's Ireland common sense probably doesn't apply :D
 
i want to make decryption and verification on the input device (usb) so i can't use some of the shelf media player.
