Abstract
Upon the receipt by an HTTP server over the Internet from a web browser for title information for audio or video data, the HTTP server retrieves the title information and sends it to the web browser along with a passcode particularly associated with the requested title information. Then, when an application server coupled to the HTTP server receives a request for the audio or video data from a viewer application associated with a web browser, the audio or video data will only be sent from a video server to the viewer application over the Internet if the request for the audio or video data is accompanied by the passcode. After sending the audio or video data to the viewer application, the passcode is invalidated. If the request for the audio or video data requests titles other than those associated with the passcode, the request is denied.
