Type: Automated Test

Overview

The CSS Negotiation\Region Check test verifies that it does not take more than 20 ms to start and end the CSS session or conduct a region check on the DVD content. This test requires a CSS-encrypted DVD. The test operates by programmatically running Windows Media Player and taking an event trace log that records the negotiation and region check events and parses the log file, looking for any event that has a timestamp of longer than the bar of 20 ms.
