1. A system comprising:
- a. a first signal source having a first analog-signal port, a first digital-signal port, and a first unique signal-source identifier; and
b. a receiver having;
i. a first analog input channel connected to the first analog-signal port;
ii. a second analog input channel; and
iii. memory having a first device field storing the first unique signal-source identifier and a first plug-identifier field associated with the first device field, and wherein the receiver associates a second device field with the second analog input channel;
iv. wherein the receiver associates the first device field with the first analog input channel.

Abstract
An entertainment system includes a digital television connected to a number of audio/video input devices. The television and at least two of the input devices support analog legacy communication schemes. The television is adapted to uniquely identify the analog output channels from each of the input devices. Uniquely identifying the analog output channels from each input device enables the television to automatically select the correct device output from among the numerous possibilities. This automation relieves the user of having to manually select the correct analog channel.
