Abstract: A system and method for routing the audio output from a selected one of a plurality of independent audio sources to an audio system for amplification/playback; the routing being based upon the movement of a user's head, and in particular the user's line-of-sight inferred from the movement. The invention employs a spatial mapping of the plurality of audio sources and routes the respective audio output of each of the sources to the audio amplification/playback system upon making the determination that the user's line-of-sight is being directed to a particular one of the audio sources.

Abstract: Methods, systems, and computer readable media can be operable to facilitate a generation of a content rating based upon user input and an insertion of the content rating into a video stream. A user interface may be utilized at a multimedia device to gather user input including a rating assigned to a piece of content by the user. The user input including the content rating may be output from the multimedia device to an upstream system over a return path. The upstream system may consolidate the received content rating with other ratings associated with the piece of content and may generate an aggregate rating for the piece of content. The aggregate rating may be inserted, as metadata, into a transport stream carrying the piece of content, and the piece of content, along with the metadata representing the aggregate rating, may be output to one or more multimedia devices.
