Method and system for automated test of end-user devices
A test system, for example for set top boxes or game consoles, includes logic to reformat media signals output by a device under test, logic to receive the reformatted media signals and to analyze them for errors, and a pluggable interface coupling the device under test to the logic to reformat the media signals.
1. A test system comprising:
conversion logic to receive media output by a unit under test and to reformat audio/video formats into converted media comprising a format compatible with test/analysis logic;
the test/analysis logic to receive the converted media and to analyze the converted media for errors;
an interchangeable cable interface module comprising cable plugs coupling the unit under test to the conversion logic, the cable plugs having a configuration unique to a make and/or model of the unit under test;
the interchangeable cable interface module comprising an identification in non-volatile memory of the make and/or model of the unit under test, the interchangeable cable interface module removable from between the unit under test and the conversion logic;
a slide onto which the unit under test is mounted;
a control to move the slide to engage cable plugs of the unit under test with the cable plugs of the interchangeable cable interface module; and
source signal selection logic to select a signal from a plurality of different sources based on the make and/or model of the unit under test and to direct a selected signal to the interchangeable cable interface module.
2. The test system of claim 1 , further comprising:
the test/analysis logic to detect the make and/or model of the unit under test.
3. The test system of claim 2 , further comprising:
configuration logic to apply the make and/or model of the unit under test to select a service provider configuration for the unit under test.
4. The test system of claim 3 , further comprising:
the service provider configuration applied to the unit under test via the interchangeable cable interface module.
5. The test system of claim 2 , further comprising:
selection logic to select the test/analysis logic to apply to the converted media according to the make and/or model of the unit under test.
6. The test system of claim 2 , further comprising:
selection logic to select the conversion logic according to the make and/or model of the unit under test.
7. The test system of claim 1 , further comprising:
testing logic to apply test signals to the unit under test via the interchangeable cable interface module, the test signals from a source other than a service provider network for the unit under test.
8. The test system of claim 7 , further comprising:
logic to select the test signals according to the make and/or model of the unit under test.
9. The test system of claim 1 , further comprising:
a retainer to engage and disengage the interchangeable cable interface module to and from the test system.
10. The test system of claim 1 , further comprising:
testing logic to apply test signals to the unit under test via a same physical medium as a service provider configuration is applied to the unit under test.
11. The test system of claim 1 , further comprising:
a high definition multimedia interface (HDMI) daughter board coupled to the interchangeable cable interface module, the HDMI daughter board configured to decode and test HDMI signals for compliance with a high bandwidth digital content protection (HDCP) specification.
