<p>PCT No. PCT/DE93/01047 Sec. 371 Date May 2, 1995 Sec. 102(e) Date May 2, 1995 PCT Filed Nov. 2, 1993 PCT Pub. No. WO94/10758 PCT Pub. Date May 11, 1994A process for transmitting and/or storing digital signals of multiple channels. This process is suited, in particular, for transmitting the five channels of 3/2 stereophony as well as for transmitting two stereo channels and three additional commentary channels. In this manner, by way of illustration, television programs with multi-language audio signals can be transmitted. This process is distinguished in that by reduction of the to-be-transmitted data, only a bit rate of 384 kbit/s is required for transmission. The reduction of the data is achieved by the K input channels being imaged in segments onto the N</=K virtual spectral data channels, by the spectral data channels being quantized, coded, and transmitted taking into consideration the principles of psychoacoustics, and by K output channels being reproduced from the transmitted bit stream with the aid of a transmitted list from the N</=K spectral data channels.</p> |
