Abstract

Systems and methods include broadcasting an entitlement management message (EMM) in a communication system using a scheduled delivery window. The systems and methods including receiving a EMM broadcast window from a distribution system, listening for the EMM during the EMM broadcast window, and receiving the EMM from the distribution system during the EMM broadcast window.

Description

[0001] Claim of priority under 35 U.S.C. §119 [0002] This patent application asserts Serial No. 61 / 023,262, entitled "Efficient Broadcast Entitlement Management Message Delivery Mechanism Using a Scheduled Delivery Window," filed January 24, 2008 Provisional Application No. , assigned to the present assignee and expressly incorporated herein by reference. Background technique [0003] Communication networks have been devised to deliver media content to recipients using cable, satellite, and mobile television. Delivery can be by unicast (one-to-one) or broadcast (one-to-many). For example, in subscription-based systems, to receive content, an Entitlement Management Message (EMM) is first delivered to a wireless device, also known as a subscriber unit. EMMs may be delivered using unicast or broadcast delivery. EMMs contain confidential data, such as logical keys, that enable users to access media content that has been protected, such as by encryption, so that only authoriz...
