PlayReady - KeyID vs. Content ID

May 23, 2011 at 11:44 AM


As I understood - the PlayReady KeyID that is used to sign the media can be used to identify the media.

That is - if Kx comes to my server, I can know its media X since it is signed with Kx.

Is this a good practice? or do you recommend adding content ID in the custom data to identify the media?

KeyID should be fine. Unless you have legacy WMDRM stuff i would suggest using that :)

Why cant the WMDRM use the KeyID too?

It can as well, when i said legacy stuff i kinda meant stuff that wasnt optimally designed to begin with ;)
