2. The system to facilitate expansion of media device interface capabilities of claim 1 , wherein the port expander further adds the one or more additional interface ports to the sink device at least in part by:

detecting a change in a state of the port expander or the plurality of media devices;

wherein the transferring the first message is consequent to the detecting the change.

3. The system to facilitate expansion of media device interface capabilities of claim 2 , wherein the change in the state corresponds to the port expander being initially connected or powered on, and the generating the first message is consequent to the detecting the change.

4. The system to facilitate expansion of media device interface capabilities of claim 3 , wherein the transferring the first message comprises broadcasting the first message.

5. The system to facilitate expansion of media device interface capabilities of claim 4 , wherein the change in the state corresponds to a second media device of the plurality of media devices being communicatively coupled to the port expander or being communicatively decoupled from the port expander.

6. The system to facilitate expansion of media device interface capabilities of claim 1 , wherein the port expander further adds the one or more additional interface ports to the sink device at least in part by:

operating to transfer content to the sink device based at least in part on audio and/or visual data via at least one interface port of the first set of one or more additional interface ports.

7. The system to facilitate expansion of media device interface capabilities of claim 1 , wherein the transferring the first message facilitates the sink device creating a set of virtual inputs so that user-selectable options are provided to allow selection of media devices via the first set of one or more additional interface ports and the native set of one or more interface ports.

8. The system to facilitate expansion of media device interface capabilities of claim 1 , wherein the port expander is further configured to:

receive a second message, from the sink device, that requests configuration information of the port expander;

wherein the first message is:

generated and transferred responsive to the second message; and

directly addressed to the sink device.

9. The system to facilitate expansion of media device interface capabilities of claim 1 , wherein each of the first set of one or more addition interface ports are of the first port type.

10. The system to facilitate expansion of media device interface capabilities of claim 9 , wherein the port expander is further configured to:

receive a second message, from the sink device, that requests information of one or more additional port types supported by the port expander;

wherein the first message:

is generated and transferred responsive to the second message;

is directly addressed to the sink device; and

comprises a descriptive name for each of second set of one or more additional interface ports.

11. The system to facilitate expansion of media device interface capabilities of claim 1 , wherein the sink device comprises one or more of a television, a television receiver, a set-top box, and/or a display device.

12. The system to facilitate expansion of media device interface capabilities of claim 1 , further comprising the sink device.

13. The system to facilitate expansion of media device interface capabilities of claim 12 , wherein the sink device comprises the port expander.

14. A method to facilitate expansion of media device interface capabilities, the method comprising:

adding, by a port expander, one or more additional interface ports to a sink device, where the sink device comprises a native set of one or more interface ports that are native to the sink device, at least in part by:

identifying a first set of one or more additional interface ports that are configured to interface with one or more multimedia devices, wherein at least some of the first set of one or more additional interface ports are of a first port type;

identifying a set of parameters, the set of parameters comprising parameter information pertaining to interface ports facilitated by the port expander, the parameter information indicating a number of ports and at least the first port type;

identifying a second set of one or more additional interface ports that are configured to interface with one or more multimedia devices, the second set of one or more additional interface ports being of a second port type;

wherein the parameter information indicates capabilities of the port expander at least partially by indicating that each of the first set of one or more addition interface ports are of the first port type and each of the second set of one or more additional interface ports are of the second port type;

wherein the first port type is different from the second port type;

transferring the first message to the sink device to indicate the first set of one or more additional interface ports and the native set of one or more interface ports.

15. The method to facilitate expansion of media device interface capabilities of claim 14 , wherein the port expander further adds the one or more additional interface ports to the sink device at least in part by:

detecting a change in a state of the port expander or a plurality of media devices communicatively coupled to the port expander;

wherein the transferring the first message is consequent to the detecting the change.

16. The method to facilitate expansion of media device interface capabilities of claim 14 , wherein the port expander further adds the one or more additional interface ports to the sink device at least in part by:
