• initiate communication of tuner update data associated with the tuner configuration input to update the rendering devices that are further configured to share the tuner of the tuner device to receive the different television content;
• receive a join request to join the shared television session from an additional rendering device;
• cause display of the join request from the additional rendering device at one or more of the rendering devices that share the tuner;
• deny joining the additional rendering device if a join deny input is received from one of the rendering devices that share the tuner;
