Type: Manual Test

Overview

The Tuner-Audio Video Capture Test (TVWLPTest) verifies that both audio and video capture must occur on the same physical device, with tightly synchronized audio/video (A/V) elementary streams--less than 100ms phase skew (which determines audio and video synchronization, failure of which causes lip-synch issues); multiple small host capture buffers (a minimum of 64 buffers and a maximum of 32 KB per buffer); and low interrupt rates (less than 500 per second).
