An apparatus for enabling feedback from a recipient of media content includes a receiver that receives a content data stream, containing media content and embedded Meta-Data, and a decoder that decodes the content data stream to extract the media content and the Meta-Data. A playback signal dependent upon the extracted content is passed to a content playback device of the content recipient. A control device interface receives a signal from a local control device operated by the content recipient and a network interface provides the desired feedback by accessing a network in accordance with the Meta-Data and the signal from the local control device of the content recipient. The Meta-Data, which may be related to the content, is embedded in the encoded media content data sequence before the sequence is transmitted or at a later stage in the transmission network.
