VIDEO/AUDIO SIMULTANEOUS TRANSMISSION SYSTEM |
| 摘要 |
The horizontal sync signal contained in the video signal from a video apparatus sometimes undergoes phase jump, resulting in failure of multiplexing of audio and video signals based on the horizontal sync signal. A sync signal switching circuit is adapted to produce a modified sync signal by switching the sync signal to a local sync signal upon occurrence of the phase jump, thereby assuring the multiplexing of audio and video signals. |
