In one embodiment, a universal media server (e.g., a set-top box) has zero or more physical audio and/or video (A/V) inputs configured to receive A/V data, and at least one Internet Protocol (IP) input configured to receive IP data. In particular, the universal media server has one or more virtual A/V inputs, each virtual A/V input corresponding to an IP-based A/V source device having a corresponding IP source address and configured to receive IP-based A/V data from the IP-based A/V source device on the at least one IP input. The universal media server also has at least one A/V output configured to selectively output A/V data according to a selected input of the physical and virtual inputs.
