1. A method for a user interaction routine for a user terminal which may be tuned to a stream of information from a provider thereof from which at least one transport stream may be demodulated, the method comprising:

  • demultiplexing a transport stream to obtain an encoded video stream and an encoded audio stream, the encoded video stream and the encoded audio stream each having a packet identifier;

    decoding the encoded video stream to provide a decoded video stream;

    retrieving overlay information stored at the user terminal;

    producing a merged information stream using the overlay information and the decoded video stream;

    decoding the encoded audio stream to provide a decoded audio stream;

    presenting user perceptible audio-visual information from the decoded audio stream and the merged information stream;

    determining whether a provided user selection is associated with interactivity processing or user terminal processing; and

    in response to the user selection being associated with interactivity processing, determining whether a time-dependent stream or a time-independent stream is selected for the interactivity processing.
