摘要 |
A data compression apparatus is proposed for data compressing at least a first and a second digital information signal (L0,L1,L2, . . . ,R0,R1, R2, . . .), each of the at least two digital information signals comprising subsequent samples. The apparatus comprises an input (1,2) for receiving the first and second digital information signal, a merging unit (6) for merging the samples of the first and second digital information signal after each other into one datastream so as to obtain a composite information signal (L0,R0,L1,R1,L2,R2, . . .). Further, a data compression unit (12) is available for data compressing the composite information signal so as to obtain a data compressed composite information signal and an output (16) is present for supplying the data compressed composite information signal.
