METHOD FOR TRANSMISSION AND/OR STORAGE OF DIGITAL SIGNALS OF MORE THAN ONE CHANNEL |
摘要 |
FIELD: transmission and/or storage of multichannel signals; transmission of TV programs with audio signal in many languages. SUBSTANCE: method requires bit transmission speed of 384kbit/s due to reducing transmitted data. For the purpose, K input channels are reflected in the form of NúK segments of virtual spectral data channels which are quantized , encoded, and transmitted including psychoacoustics principles and then K output channels are reproduced from transmitted bit stream by means of jointly transmitted list of NúK spectral data channels. EFFECT: provision for transmitting two stereo channels and three additional channels of comments; improved data transmission speed. 10 cl |
