VIDEO DISTRIBUTION AND PLAYBACK

摘要

Systems and methods are disclosed for providing a content delivery network with one or more network-connected audiovisual players. A content delivery network provider can provide an access module residing within a network-connected audiovisual player wherein the access module can be configured to control the player. The access module can be configured to function within a gateway environment on the player such that the gateway environment passes commands from the access module to the firmware or secure module on the player operating in a secure environment. As a result, each player with the access module can become a part of the content delivery network as the content delivery network provider can control the network-connected audiovisual players. The content delivery network can implement multi-level access controls to licenses and encryption keys to secure audiovisual content.
