ABSTRACT:
Systems and methods to license combinations of one or more data streams from an encoded file including multiple data streams are described. In one aspect, the encoded file is accessed from a data source. A header is generated to specify a first group of one or more data streams for licensing independent of a second group of one or more data streams. The data stream content in the first group is not equivalent to the data stream content of the second group. A number of business rules are identified to indicate respective licensing strategies for the data streams in the first and second groups. A data file is generated to encapsulate the header and an encrypted version of the encoded media. An end-user is provided access to the data streams in the first and/or second groups via the data file and the header according to the respective licensing strategies.
