System and method for transacting access to media
InactiveUS20060253399A1Secure transmissionReduce usageAcutation objectsAnalogue secracy/subscription systemsContent distributionNetwork connection
A flexible product distribution and payment system for computer network based electronic commerce is disclosed. Primary content data is made available to customers through a detachable local storage medium, such as a DVD or CD-ROM disc, or over a network connection. The primary content is capable of being accessed and played back through a computer or game console at the customer site. The primary content distribution may comprise a superset of content that is intended to be used by the customer. The customer is allowed to view and access the encoded primary content, and is charged only for the primary content that is used. Content that is encoded on the medium but that is not used by the customer remains on the medium but is not charged. A content database and customer database maintained at the primary customer site maintain records of products ordered and used by the customer, as well as identification and use patterns associated with the user. Authentication and use trigger data associated with the distributed content alert the primary content server computer when customer use has occurred and when a charge to the customer is appropriate.

Correlating detected patterns with content delivery
In the present invention a content distribution network delivers content that can include training, entertainment, assessment, and evaluation among many other types of content. Content can be delivered on-demand to devices operated by users in local or remote locations or can be delivered live in a present local or live-streamed to remote locations. In each of these cases the user, thru the user device, can provide valuable feedback to the content distribution network to improve content delivery and user content retention in the form of correlating detected patterns with the content being delivered. An image sensor attached to a user device captures facial expressions as patterns and transmits them to a content manager that aligns the pattern with the content and determines a sentiment corresponding to the pattern. The content manager can improve the user's content reception by implementing a workflow responsive to the corresponding sentiment pattern.
