Abstract:
A method and apparatus support delivering a video media stream to a wireless device by exchanging communication signals through a secure communications interface to establish first and second communication channels. The channels may be according to different communication protocols. A first portion of the streamed video media stream over the first communication channel is encrypted while a second portion of the video media stream over the second communication channel is not encrypted. The second portion is based on the first. In addition to encryption of only the first portion, one embodiment includes using different communication protocols for the first and second channels to further enhance secure media delivery.
