It is disclosed a method for changing channel in a television appliance. Upon reception of a user command to tune on a desired channel (301), the television appliance is tuned on the desired channel (302) and audio and video packets are received. Video and audio packets are buffered in relative buffers, so that audio and video output can be generated by processing the buffered packets. Video output frame rate is increased from a first, slower, frame rate to a predetermined final frame rate. Independently from the frame rate increasing law, video output frame rate is raised to the final frame rate as soon as an audio output can be generated from the buffered video packets which is synchronized to the video output. A television appliance implementing the method is also disclosed.
