          • Introduction
          • Parameters
          • Characteristics
          Differential VGA audio and video signal transmission system is used for high quality transmission of VGA signal and audio signal of multimedia audio and video system in metro train compartment. It is specially designed for the actual environmental conditions in metro train carriage by our company.

          According to the company's proprietary technology, VGA signals are optimized and coded to send, which can well suppress common-mode noise and various interference signals, and transmit VGA signals and audio signals through unshielded five types of network lines. The system supports input of various signal formats, supports 640 * 480, 800 * 480, 800 * 600, 1280 * 1024, 1600 * 1200 and other resolutions. It has high quality and rich color.
