Abstract

A data recording and/or reproducing apparatus having actuating buttons or adjustment volumes which enable a wide variety of processing operations despite a limited operating space, and which is able to display levels of plural audio data or to display various other data on a limited display area without detracting from viewability. To this end, the apparatus recording and/or reproducing includes a unit for recording and/or reproducing data for a non-linear accessible recording medium, at least one input port and at least one output port. The input port and the output port time-divisionally access the recording and/or reproducing unit to process the data inputted to the input port to output the processed data to the recording and/or reproducing a unit. The data reproduced from the recording and/or reproducing unit is processed by and outputted from the output port. The apparatus also includes a port actuation button for selecting the input and output ports, an actuation selection button for selecting recording or playback for the input port or the output port as selected by the port actuation button, and a controller for performing control so that the recording operation or the playback operation as selected by the actuation selection button will be executed by the input port or the output port as selected by the port actuation button.

Dependent claims

A data recording and/or reproducing apparatus comprising recording and/or reproducing means for recording and/or reproducing data for a non-linear accessible recording medium, at least one input port and at least one output port, said input port and the output port time-divisionally accessing said recording and/or reproducing means, said input port outputting the data inputted to said recording and/or reproducing means and said output port being fed with the data reproduced by said recording and/or reproducing means to output the data, wherein the apparatus further comprises:

level detection means for detecting the level of audio data contained in data inputted to and outputted from the input and output ports;
control means fed with level data detected by said level detection means for outputting control data for displaying the audio level;
and
display means fed with level data detected by said level detection means for displaying the audio level inputted to and, outputted from the input and output ports based on said level data;
wherein said display means is a monitor provided on a front side of the data recording and/or reproducing apparatus for displaying thereon the audio level of said audio data based on the control data outputted by said control means;
said control means outputting control data configured for performing control so that respective channels of said audio level will be displayed from port to port in display areas of said monitor based on the numbers of said input and output ports, the number of the audio levels that can be displayed in the respective display areas of said monitor, the number of channels contained in the audio data inputted or outputted to or from the respective ports and on said level data.

An audio level displaying method for a data recording and/or reproducing apparatus comprising recording and/or reproducing means for recording and/or reproducing data for a non-linear accessible recording medium, at least one input port and at least one output port, said input port and the output port time-divisionally accessing said recording and/or reproducing means to output the data inputted to said input port to said recording and/or reproducing means, the data outputted from the recording and/or reproducing means being inputted to said output port, said port actuation method comprising:

a first step for detecting the audio level contained in said data inputted to said input port and to said output port;
and
a second step for displaying said audio level detected at said first step;
said second step displaying respective channels of said audio level from port to port in display areas of a monitor provided on the front side of the data recording and/or reproducing apparatus based on the numbers of said input and output ports, the number of channels contained in the audio data inputted to the respective ports, the number of display areas and on the audio data detected in said first step.
