▲环绕声电视又一种图象伴音系统的研制工作正在由NBC进行试验。此项试验是将环绕声伴音信号与MTS立体声信号一起传输。环绕声最开始出现在电影伴音中,由于电影中的环绕声信息是经矩阵处理成两个通道的信号,因此在进行传输时,不需附加另外的伴音信号通道。试验网络将测试环绕声在各种不同条件时的重现性。试验包括卫星传输,VHF和UHF频段传输及
▲ Surround Sound Television Another audio-visual system developed by NBC is being tested. This test transmits the surround sound signal together with the MTS stereo signal. Surround sound initially appears in the soundtrack of the movie. Since the surround information in the movie is a matrix-processed signal of two channels, there is no need to attach additional audio signal channels during transmission. The test network will test the surround sound reproducibility under a variety of different conditions. Tests include satellite transmission, VHF and UHF band transmission and
