V2A Timing Display (TVM-A3-OPT V2A only)

NOTE: The TVM-A3-OPT V2A option is only available when the TVM-A3-OPT 3TL or TVM-A3-
OPT 5TL is purchased. The V2A option must be used with a GEN-STAR or an X75HD/X75SD
device containing the Video/Audio Timing test signal.
The TVM-A3-OPT V2A option is used to receive a VA2 test signal and analyze the
timing between the video and the audio. The V2A (Video-to-Audio) Timing Display
menu is used to enable and disable the Lip Sync Timing display. After analysis, the
V2A Lip Sync Timing display, when enabled, shows the audio and video timing
differences (if any) that occur during the following processes:
• Up, cross, and down conversion
• Analog-to-digital conversion
• Digital-to-analog conversion
• MPEG coding and decoding
Lip sync indicators appear next to each channel in the bar graph and CineSound
displays. The markers indicate the channel number and the timing difference in
milliseconds. The indicators do not appear on the loudness display. Positive numbers
indicate that the audio is leading the video. Negative numbers indicate that the audio is
lagging the video. A question mark (?) appears when no V2A signal is present, no
video signal is present, or no audio signal is present.
