Table 2: Trial 1 Videotape-Testing Procedure
| Step |
Replay each tape. |
| 1 |
Identify audio-track configuration. |
| 2 |
Optimize playback using an automatic tracking control. |
| 3 |
Identify replay-tracking position at three tape locations. |
| 4 |
Detect and plot radio-frequency waveform. |
| 5 |
Broadly group as many tapes as possible according to similar radio-frequency waveform shape, tracking position, and audio configuration. |
| 6 |
Further separate tapes into groups using 6a and 6b. |
| 6a |
Visually compare plots. |
| 6b |
Compare overlaid similar radio-frequency waveforms at optimum and central replay-tracking position. |
