Implementing iPhone DRM for audio and video

Question

I did a lot of searches, to no avail,
I am interested to know that my own or third-party options are designed to implement DRM to protect sound (say, in a similar scenario) and video. (for VOD applications)
I saw the mention of widescreen, but for all content, apparently from 18 months to 2 years.

What are my options for implementing DRM on iPhone?

Answer 1

There are PlayReady or Widevine DRM solutions for iOS, such as this one in Inside Secure. They provide an SDK for integrating audio / video DRM protection in applications (disclaimer: I work there).
