Abstract

Abstract An optical disc reproducing apparatus in which the type of the optical discs 2 is discriminated by a disc type discriminating device, the function of a pointing device 74 is displayed by a plurality of light emitting diodes 77 provided in the pointing device and in which a controller performs a switching control of the function display by the light emitting diodes 77 depending on the type of the optical disc 2 indicated by a discriminating output of the disc type discriminating device so that the operability of the CD-I player may be improved because the functions of the pointing device associated with the types of the optical discs to be reproduced are displayed by a display device provided in the pointing device.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 229 words
An optical disc reproducing apparatus comprising: optical disc reproducing means for reproducing an optical disc on which only audio digital information is recorded or an optical disc on which non-audio digital information is recorded in addition to the audio information, a pointing device for generating a command signal corresponding to one of a plurality of operational modes of the optical disc reproducing means in response to a selection input by a user of the optical disc reproducing apparatus, provided with an X-Y device and trigger buttons, display means provided in the pointing device for indicating the operational modes which can be selected by the pointing device, disc discriminating means connected to the optical disc reproducing means for discriminating the type of the optical disc being reproduced by the optical disc reproducing means, reproduction controlling means connected to the pointing device for designating the operational modes which are selectable by the pointing device depending on the type of the optical disc designated by a discriminating output of the disc discriminating means, the reproduction controlling means, upon receipt of a command signal from the pointing device, controlling the operation of the optical disc reproducing means to perform a selected operational mode, and display controlling means for changing the display on the display means depending on the type of the optical disc designated by the discriminating output of the disc discriminating means.
Claim 2
Dependent Claim 229 words
An optical disc reproducing apparatus comprising: optical disc reproducing means for reproducing an optical disc on which only audio digital information is recorded or an optical disc on which non-audio digital information is recorded in addition to the audio information, a pointing device for generating a command signal corresponding to one of a plurality of operational modes of the optical disc reproducing means in response to a selection input by a user of the optical disc reproducing apparatus, provided with an X-Y device and trigger buttons, display means provided in the pointing device for indicating the operational modes which can be selected by the pointing device, disc discriminating means connected to the optical disc reproducing means for discriminating the type of the optical disc being reproduced by the optical disc reproducing means, reproduction controlling means connected to the pointing device for designating the operational modes which are selectable by the pointing device depending on the type of the optical disc designated by a discriminating output of the disc discriminating means, the reproduction controlling means, upon receipt of a command signal from the pointing device, controlling the operation of the optical disc reproducing means to perform a selected operational mode, and display controlling means for changing the display on the display means depending on the type of the optical disc designated by the discriminating output of the disc discriminating means.
Claim 3
Dependent Claim 27 words
The optical disc reproducing apparatus as claimed in claim 1 wherein function display patterns on the display means are provided by a plurality of light emitting diodes.
Claim 4
Dependent Claim 82 words
The optical disc reproducing apparatus as claimed in claim 1 wherein the reproduction controlling means designate the X-Y device and the trigger buttons of the pointing device as a reproduction command key, a braking key, and a stop key, respectively, when the optical disc on which only the audio information is recorded is reproduced by the optical disc reproducing means, the reproduction controlling means accepting the command signal of the pointing device for controlling the operation of the optical disc reproducing means.
Claim 5
Dependent Claim 88 words
The optical disc reproducing apparatus as claimed in claim 1 wherein the reproduction controlling means designate the X-Y device and the trigger buttons of the pointing device as an X-Y direction command key, an execute key, and a stop key, respectively, when the optical disc on which the video information is recorded in addition to the audio information is reproduced by the optical disc reproducing means, the reproduction controlling means accepting the command signal of the pointing device for controlling the operation of the optical disc reproducing means.
