Resumption of play for a content-delivery session

摘要

Multimedia content may be delivered to content consumer devices via a content-delivery network. Encrypted content and cryptography keys for decrypting the content may be distributed from a data center to various nodes of the content-delivery network, each node acting as a semi-independent content-delivery system. Each content-delivery system is capable of delivering received content to end-users and implementing a key-management scheme to facilitate secure content-delivery and usage tracking, even when the content-delivery system is disconnected from the data center. Further, each content-delivery system may generate an authorization-token that can be transmitted to other systems in the content-delivery network, enabling the other systems to quickly determine that a request to resume a previous content-delivery session has already been authorized.

主权项

1. A computer-implemented method for verifying access-rights to content, the method comprising:
authorizing, at a content-delivery system (“CDS”) disposed on a vehicle, a content-delivery session to deliver selected content from the CDS to a mobile consumer device via an in-vehicle network for the vehicle, the selected content selected from a collection of content; transmitting, from the CDS to the mobile consumer device, one or more keys for decrypting encrypted content-data received by the mobile consumer device during the content-delivery session, the encrypted content-data representing the selected content; generating, at the CDS, an authorization-token indicating that the CDS authorized the content-delivery session and transmitting the authorization-token; receiving, at a data center, the authorization-token; receiving, at the data center, a request to resume the content-delivery session; authorizing or denying by the data center, based on the authorization-token indicating that the CDS authorized the content-delivery session, the requested resumption of the content-delivery session; and when the requested resumption is authorized: transmitting one or more keys for decrypting encrypted content-data representing the selected content.
