TV SIGNAL CONVERTING APPARATUS

摘要

The TV signal contains a video signal and two audio carrier signals and is received over a single channel. The TV signal is converted into a video signal of a preset channel. The converter contains demodulators (1) for perception of the video signal and generating a base band video signal and the two audio carrier signals. Separators and adjusters (2) are used to separate the generated two audio carrier signals and adjust the level of at least one audio carrier signal. Adders (3) are used for the separated and adjusted two audio carrier signals adding to the perceived base band video signal. Modulators for a carrier of a frequency corresp. to the preset channel of the video signal provide the modulation and generation of the two audio carrier signals. USE/ADVANTAGE - For community aerial TV, with precise separation in stereo transmission, audio-multiplex transmission etc.
