A method and apparatus for processing object-based audio signals for reproduction through a playback system is provided. The apparatus receives a plurality of object-based audio signals in at least one audio frame. In addition, the apparatus receives at least one audio object command associated with at least one object-based audio signal of the plurality of object-based audio signals. In addition, the apparatus processes the at least one object-based audio signal based on the received at least one audio object command. Further, the apparatus renders a set of object-based audio signals of the plurality of object-based audio signals to a set of output signals based on the at least one audio object command. The at least one audio frame may be received from one of a set top box, an OD player, or a television. The apparatus may be an AV receiver or a television.

Implementations of the system and method use an existing management server infrastructure to deliver video-on-demand or streaming content, including real-time live streaming. Existing client content playback devices, such as IPTVs, may be employed to stream content items, obtain advertisements, track user's viewing behaviors, and the like. By reusing existing client devices, there is no need for additional hardware purchases on the user side. By reusing existing management server infrastructures, capital expenses are also reduced. In such a system, a user can watch both video-on-demand and streaming audiovisual content.
