Infrared Receivers: Protocol Used

What infrared protocols does the Macintosh TV and Macintosh 630 family work with? I want to use a universal remote control, but I don't know what command set I need.
Both the Macintosh 630 family and Macintosh TV use the standard Sony command set. A universal remote control that supports the Sony command set can be used to control these devices.

There are no specific infrared receiver (IR) protocols published by Apple Computer, Inc.
