Abstract
Subscription based content is decrypted for one or more trial periods without shortening the subscription period for the device. The subscription period for the content does not start until the expiration of the last trial period. The subscription logic included with the device monitors a packet value received in a broadcast to determine when the device is receiving a packet within a trial period. The packet value is time-based such that the subscription logic can determine when the device has exceeded the number of allowed trial periods as well as to determine when the subscription ends.
