发明名称 SYSTEM AND METHOD FOR TRACKING USE OF STREAMING MEDIA
摘要 A system for providing pre-paid access to digital streaming media tracks a number of credits associated with each subscriber. The system measures subscriber use of a digital media stream by embedding frame indicators in the stream at periodic intervals. Each frame indicator includes a URL or other response address. The frame indicators may be inserted, for example, in an RTP header of the digital media stream. Subscriber devices, upon receiving frame indicators, send responses to the response address. With each response received from a subscriber device, the system decrements the number of credits available to the subscriber. The system may stop delivering the media stream to a subscriber who runs out of credits, until that subscriber purchases more credits.
