Title: Changing communication mode in a CATV pathway using mute commands

Abstract: A cable node and a cable hub that communicate on a CATV network are configured to switch communication modes without signal loss or degradation due to delays in switching communication modes. In particular, a cable node sends one or more mute commands in an outgoing data stream to the cable hub, causing the cable hub to disable the RF outputs. Afterward, or along with the one or more mute commands, the cable node can send a switch mode command, thereby causing the cable hub to switch to the appropriate next communication mode, such as a communication mode using a new compression rate. When the cable hub has switched to the appropriate next communication mode, the cable hub can then properly receive and decode a corresponding data stream using the next communication mode.
