Multimedia device test system
A test system includes a supervisor unit coupled to a control interface; the control interface coupled to first and second test modules, each test module comprising a first logic module to test macro blocking errors; a second logic module to perform optical character recognition; a third logic module to perform signal to noise ratio measurement; and a fourth logic module to perform random noise measurement; each test module coupled to a device under test, the four logic modules applied to test a menu-driven video decoding device.
1. A test system comprising:
a supervisor unit coupled to a control interface;
the control interface coupled to first and second test modules, each test module comprising
a first logic module to test macro blocking errors;
a second logic module to perform optical character recognition;
a third logic module to perform signal to noise ratio measurement;
and a fourth logic module to perform random noise measurement;
each test module coupled to a device under test, the four logic modules applied to test a menu-driven video decoding device.
2. The test system of claim 1 , further comprising:
each test module comprising a fifth logic module to communicate commands to setup the proper menus on the device under test.
3. The test system of claim 1 , further comprising:
the supervisor unit comprising logic to configure a behavior of each logic module.
4. The test system of claim 1 , each test module comprising server logic, the server logic adapted to control each logic module as a server service.
5. The test system of claim 1 , further comprising:
the test modules comprising logic to store in nonvolatile memory one or more reference patterns for use by the logic modules.
6. A process comprising:
a supervisor unit communicating control commands via a control interface to multiple test modules, the commands communicated to each of a first logic module to test macro blocking errors; a second logic module to perform optical character recognition; a third logic module to perform signal to noise ratio measurement; and a fourth logic module to perform random noise measurement;
each logic module obtaining a video frame from a menu driven video decoding device under test and operating on the video frame according to the control commands received from the supervisor unit;
each logic unit communicating a result of operating on the video frame to the supervisor unit.
7. The process of claim 6 , each test module comprising server logic and communicating with the supervisor unit via a client-server communication model.
