Hi,

I'd like to develop a multimeida player with DRM features. Is it
possible to use for example 'forward lock' using JSR 135? I am unable
to find any more detailed info on the web.

Thank you
-Piero

I do not know how on earth all the line breaks disappeared from my previous email making it illegible.

Let's try one more time (sorry for wasting the bandwidth)

As an example the MMAPI implementation on:

S60 3rd Edition devices support OMA DRM 1.0 for audio.

S60 3rd Edition Feature Pack devices support OMA DRM 1.0 for all content types.

Series 40 3rd Edition Feature Pack devices (for example Nokia 5300 and 7390) support DRM protected content.

Hi,

There's no DRM specification in the JSR135, but the API allow to open a file, encrypted or not. Then it depends on the implementations (you'll have to check device per device).

JSR 135 allow this trough file locator :
Manager.createPlayer("/pathToFile/audioFL.dm");
Manager.createPlayer("/pathToFile/audioOMA1SD.dcf");

Security scheme associated to native DRM should not allow you to open an InputStream on a forward lock file (as there's no encryption in FL) Forward lock should not be called DRM, it's not real protection.

It could be possible on OMA1 SD files, but I did not find any device allowing this.
