A method and device for communicating private application data, along with audio data (e.g., MPEG-2 encoded audio data) and video data (e.g., MPEG-2 encoded video data), from a first location to a second location. The private application data is either stuffed into a header portion of packets of encoded audio or video data, or packetized and multiplexed with packets of encoded audio or video data. The multiplexed packets form a packet stream which is communicated to the second location.
