Abstract
Circuits, methods, and apparatus for testing media player accessories. One example includes an accessory validation system including hardware, firmware, and software. This example provides two test modes, referred to a sniff mode and an emulation mode. In the sniff mode, a test box may be inserted between an accessory and a media player. Traffic between the accessory and media player may be monitored and the presence of errors may be determined. In the emulation mode, the accessory validation system hardware emulates a media player. The emulator provides various types of responses to the accessory that would otherwise occur infrequently with an actual media player. The tests to be completed in these modes are compiled based on the category of functions that an accessory maker wishes to claim for the accessory. These category claims are then converted into a number of rules. From these rules, specific tests are generated.
