the echo canceller 108 takes the audio signal that would emit from the television or display device or audio system that is outputting an audio signal coming through the set top box 11 and generate a cancelling signal that would mix with the signal coming into the set top box 11 via the audio pick up device thus cancelling the unwanted audio signal and preventing unwanted feedback the transmission encoder 110 encodes data from the echo canceller 108 so as to prepare it to be transmitted to a desired networked target the audio video combiner 112 merges the audio and video outbound feeds together this is accomplished by taking the audio signals from the echo canceller 108 and combining them with the video signal generated by the local video encoder 106 in other embodiments the transmission encoder 110 is not included and the audio and video feeds are transmitted as separate signals the combiner mixer 113 combines different sources of the audio video signals which are to be provided to the television 118 or desired display device and routes the combined signal to the output interface 101 it is contemplated that sms gaming audio video audio call video call video audio call interactive menu displays co viewing displays and others may be provided to the output interface 101 by the combiner mixer 113 in some embodiments the combiner mixer 113 includes an encoder while in other embodiments an encoder is provided in the output interface 101 referring now to fig3 the process of initiating a coviewing session between.
