Abstract

Methods and systems enable receiving on mobile devices credits, tokens or coupons from mobile TV broadcast service providers. Credits may be delivered via direct unicast messages such as SMS or e-mail, or via broadcast provisioning messages. Subscription response messages may be used to deliver credits to mobile devises which transmit a request for service. Broadcast service providers may push credits to mobile devices by transmitting a solicited pull message or a credit grant push message. Credits may be sent to mobile devices within a credit response message or a long term decryption key message. Credits may be used a purchase transaction, with the broadcast service provider controlling redemption of credits by sending an a long term decryption key message via a unicast network or a short term decryption key message via the broadcast network to cause mobile devices to decrement their stored credits.
