Abstract
In an apparatus for connecting first and second digital data which overlap before and after a connecting point, and in which said digital data is muted after the connecting point for limiting errors in the output from the apparatus, the combination of a detector which detects when the muting of the second digital data terminates and which generates detection signals in response thereto, and a cross-fader which gradually fades out the first digital data and gradually fades in the second digital data in response to the detection signals.
Claims20
In an apparatus for reproducing from a record medium a composite digital data signal that was formed by connecting first and second digital data signals, in which said first and second signals are interleave-coded so that the signals overlap before and after a connecting point between the respective signals, thereby forming the composite digital data signal, and in which said composite digital data signal is muted in the vicinity of said connecting point for limiting errors in the output from the apparatus;
- the combination of:
- detector means receiving said composite digital data signal for detecting a termination point of said muting of said second digital data signal and generating a detection signal upon such detection;
- and
- cross-fading means receiving said composite digital data signal and said detection signal for gradually reducing data values of said first digital data signal and gradually increasing data values of said second digital data signal in response to said detection signal.
In an apparatus for reproducing an information signal from an edited signal formed by connecting first and second audio PCM data from first and second magnetic tapes which have been splice edited together, each of said first and second audio PCM data being comprised of an even series and an odd series of digital words, and in which said edited signal is muted at the connection of said first and second data at a splice point for limiting errors in an output information signal from the apparatus;
- the combination of:
- error detector means receiving said edited signal for detecting errors in said even and odd series of digital words in the vicinity of the connection between the first and second audio PCM data and generating respective even and odd muting request signals upon such detection;
- splice point detector means receiving said edited signal for detecting the splice point between said first and second audio PCM data and generating a splice control signal in response thereto;
- and
- cross-fading means receiving said even and odd muting request signals, said splice control signal, and said edited signal for fading out said first audio PCM data in response to termination of a first one of said even and odd muting request signals while said splice control signal is present and in response to generation of a second one of said even and odd muting request signals, and for fading in said second audio PCM data when one of said even and odd muting request signals terminates.
