Abstract
A system and method for switching data packet traffic distribution across diverse transmission medium according to detected quality of service characteristics for a given data packet rate from server to client. It should be recognized that diverse medium are not interdependent with regard to fading or signal strength considerations. One mode of switching comprises switching all the data packets from transmission on a first medium to transmission over a second diverse medium. In a second mode of switching the distribution is changed according to a media-time coding mechanism in which typically data is being transmitted simultaneously across more than one of the multiple diverse medium. The data packet transmissions preferably comprise audio-video data packet streams, such as MPEG-2 streams. By way of example, the diverse transmission medium may comprise a wireless connection (i.e. WiFi) used in combination with a power-line network connection, such as within a home network.
