On-demand download of partial encrypted content for partial super distributed content
Abstract:
A request to render content associated with a first super distributed content file is detected by a content rendering device. At least one portion of the content associated with the first super distributed content file is determined to be missing from the first super distributed content file. A second file including the at least one portion of the content missing from the first super distributed content file is obtained from a server. The at least one portion of the content of the second file includes partial encrypted portions of the content associated with an encryption system of the content rendering device. A content output stream including decrypted partial encrypted portions of the content of the second file and the content associated with the first super distributed content file is generated. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
