PREVENTING UNAUTHORIZED DISTRIBUTION OF MEDIA CONTENT
摘要
One aspect here described is a method for providing media content while preventing its unauthorized distribution. The method includes transmitting from a client to an administrative node a request for delivery of an instance of media content (IMC); determining which content source (CS) of a plurality of CSs to provide delivery of the IMC, provided the client is authorized to receive the IMC; transmitting to the client an access key and a location of the IMC; transmitting from the client to the CS a second request and the access key; in response to receiving the second request and the access key, transeferring the IMC from the CS to the client; transmitting from the client to the administrative node an indicator indicating a successful transfer of the IMC; and generating a transaction applicable to the client and associated with the transfer of the IMC to the client.
