The method receives a request to change the first set of characteristics to a second set of characteristics. The request includes information requesting a switch from the second state to the first state. In response to receiving the change, the method sends a second frame to continue pushing content to the client in the stream based on the second set of characteristics and transitions from the second state to the first state.

Abstract: Viewing policies are received for a media program being offered via linear programming. The viewing policies are transformed to a linear prioritized list of audiences and respective actions to perform on a per user basis for presentation via the live linear programming. The actions analyzed to determine a base action associated with sending a base content stream for the media program. An audience associated with the base content stream and previous audiences associated with previous actions that have a higher priority in the linear prioritized list than the content stream audience are selected. An audience definition for the media program is generated defining restrictions based on the base audience and the previous audiences. The audience definition is used to determine whether users may view the media program based on characteristics of the users before the media program is available via the live linear programming.
