“灰度同步”是一种能使电视图象信噪比改善3dB,并能有效地实现电视伴音同步传声的技术。我们在研究电视同步信号与伴音信号数字处理的基础上,研制出了能传输PAL制彩色全电视信号和适应过频偏接收的“灰度同步”设备。文中着重介绍了它的方案和实验结果。
“Grayscale synchronization” is a technology that can improve the signal-to-noise ratio of the television image by 3dB and effectively realize the simultaneous sound transmission of the television sound. Based on the study of the digital processing of TV synchronization signals and audio signals, we developed a “gray-scale synchronization” device that can transmit PAL full-color television signals and accommodate over-frequency offset reception. The article focuses on its program and experimental results.
