Interactive audio teaching aid
First Claim
1. A microprocessor controlled compact digital disk system adapted for providing both a teaching function and an entertainment function, said entertainment function making use of a plurality of compact disk control switches, comprising:
- (a) keyboard means for establishing a selection code signal to recover audio data from discrete predetermined locations on said compact digital disk responsive to a manual input, said keyboard means establishing said selection code when said teaching function is enabled;
(b) mode selection means for directing said microprocessor to enable one of said teaching or entertainment functions, said mode selection means including (1) a mode select switch having two positions, and (2) a mode select interface coupled to said mode select switch and said microprocessor for enabling said plurality of compact disk control switches in one of said positions and mutually exclusively enabling the system responsive to said selection code signal established by said keyboard means in the other of said positons; and
,(c) memory means for transmitting to said microprocessor one of a multiplicity of predetermined control code signals responsive to said selection code signal from said keyboard means.

Abstract
An interactive compact disc system (10) having a teaching mode in addition to an entertainment mode is provided for the recovery of a predetermined aural response from predetermined randomly accessed storage on a compact digital disc. The interactive compact disc system (10) includes a mode select switch interface (26) which is coupled to microprocessor (22) by data bus (34) and address bus (32) for selecting the desired operational node. A keyboard (12) which includes a removable graphic overlay, provided for use in the teaching mode, is coupled to keyboard decoder/driver (14). Keyboard decoder/driver (14) generates a unique character code for each of the keyboard switches in keyboard (12). Microprocessor (22) uses that unique character code to generate an address for accessing the track encoder read only memory (24). Track encoder read only memory (24) provides a lock-up table which in effect cross references each keyboard key switch with a discrete audio segment on a compact digital disc located in disc playback unit (30).

9. An interactive compact disk system having a teaching mode and an entertainment mode, where said teaching mode provides a means for recovery of a predetermined aural response from non-sequential discrete storage locations on a compact digital disk, said compact disk system having a plurality of control switches for use in said entertainment mode, comprising:
-
(a) interface means for (1) converting a mechanical input to a digital code, and (2) establishing an interrupt signal responsive to said mechanical input for initiating the temporary storage of said digital code, said digital code being representative of said discrete storage location on said disk; (b) microprocessor means for (1) establishing a multiplicity of signals to control said compact disk system, at least one of said multiplicity of control signals being a track selection signal defining said storage location on said disk, and (2) establishing an encoder address responsive to said digital code when said microprocessor is operating in said teaching mode; (c) mode control means for selecting between said teaching mode and said entertainment mode, said teaching mode selection enabling said response by said microprocessor means to said digital code from said interface means, said entertainment mode enabling said plurality of control switches, said mode control means including (1) a mode select switch having two positions, each of said two positions representing one of said mutually exclusive modes, and (2) a mode select interface coupled to said mode select switch and said microprocessor; and
,(d) memory means for providing a predetemined control code signal responsive to said encoder address generated by said microprocessor means, said control code signal defining said tract selection signal. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
