Command and control transfer

A home entertainment system, comprising:

• a plurality of nodes;
• a video display unit;
• and
• a controller;
• the plurality of nodes including a first node configured to dynamically generate and transmit to the video display unit a node navigation tree,
• receive a node navigation input from the controller identifying a particular node in the node navigation tree,
• modify and transmit to the video display unit a subset of the node navigation tree based on the node navigation input from the controller,
• generate and transmit to the video display unit a node function list including one or more functions pertaining to the identified node,
• receive a node function input from the controller corresponding to a particular node function in the node function list;
• and
• transmit a command to the identified node based on the node function input.

A computer readable medium having stored thereon sequences of instructions for causing one or more processors employed in conjunction with a system comprising a plurality of nodes and a video display unit to:

• dynamically generate a node navigation tree;
• transmit the node navigation tree to the video display unit;
• receive a node navigation input identifying a particular node in the node navigation tree;
• modify a subset of the node navigation tree based on the node navigation input;
• transmit the modified subset of the node navigation tree to the video display unit;
• generate a node function list including one or more functions pertaining to the identified node;
• transmit the node function list to the video display unit;
• receive a node function input corresponding to a particular node function in the node function list;
• and
• transmit a command to the identified node based on the node function input.
