Secret Sauce: the Platform Capabilities Matrix

For a closer look at the performance details that underlie the PCS display, DHCAT users can click the detail button in the lower left corner to bring up the Platform Capabilities Matrix (PCM) screen. This is where the rubber meets the road, as the PCM clearly shows which scenarios a platform did very well, passably well, and not well at all. The PCM provides a graphic overview of the test platform’s performance at each capability level, and in scenario-by-scenario detail. Each scenario tested is shown with a color-coded display that indicates the performance achieved.

• Green = Excellent
• Yellow = Good - Acceptable
• Red = Poor - Failure

Multi-primitive scenarios receive an overall grade equivalent to that of the worst performing primitive. Similarly, scenarios that are tested in multiple instantiations (to accommodate multiple video codecs) receive an overall grade equal to the worst performing primitive in the best performing instantiation.
