Abstract
The paper concentrates on a lip-sync test for DTV with respect to audio and video signals using the digital bitstream. We propose a new lip-sync test method which does not affect the current program by use of the TATS (transient effect area test signals) and an additional sub-channel audio signal. The experimental result shows that the time difference between the audio and video signals can be easily measured by a captured oscilloscope waveform at any time.
