     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     An embodiment of an audio video apparatus controller according to the present invention will hereinafter be described with reference to the drawings. 
     FIG. 1 is a systematic block diagram showing a controller 1 to which the present invention is applied and a variety of audio video apparatus 50 which are controlled in operation by the controller 1. In that case, FIG. 1 is formed of FIGS. 1A and 1B drawn on two sheets of drawings so as to permit the use of a suitably large scale. 
     The controller 1 is mainly formed of a microcomputer (control means) 3 and controls the operation of the audio video apparatus 50 in accordance with an operation signal input from a remote controller 100 through a light receiving unit 7 and processing data or the like stored in a program ROM (read only memory) 5 by way of a bus interface 10 and a bus line shown by a bold line. 
     An operation signal necessary for energizing the audio video apparatus 50 is stored in a start buffer 9, an operation signal necessary for stopping the operation of the audio video apparatus 50 is stored in a stop buffer 11, and control contents and so on are displayed on the picture screen of a television monitor 13, if necessary (see FIG. 3). 
     The audio video apparatus 50 includes an audio video selector 50A for selectively switching and supplying signals delivered, respectively, from a television tuner (TV) 50a, a VTR-A 50b, a VTR-B 50c, a laser disc player (LDP) 50d, and a BS (broadcast satellite) tuner 50e to the television monitor 13. 
     The audio video selector 50A interchanges audio signals between it and an audio amplifier selector 50B; and the audio amplifier selector 50B selectively switching and supplying audio signals delivered, respectively, from an audio tuner (AM, FM) 50f, a compact cassette recorder (TAPE) 50g, a digital audio tape recorder (DAT) 50h, and a compact disc player (CDP) 50i to a loud speaker 50C. 
     The audio video selector 50A enables an output signal from the television tuner 50a, the laser disc player 50d or the BS tuner 50e to be supplied to the VTR-A 50b and VTR-B 50c, while the audio amplifier selector 50B enables an output signal from the audio tuner 50f or from the compact disc player 50i to be supplied to the compact cassette recorder 50g and the DAT 50h. Also, the audio amplifier selector 50B enables the dubbing to be effected between the compact cassette recorder 50g and the digital audio tape recorder 50h. 
     A situation wherein an audio signal is exchanged between the audio video selector 50A and the audio amplifier selector 50B, is exemplified by the audio signal of the BS tuner 50e being recorded by the DAT 50h or the like. 
     As seen in FIG. 2, the remote controller 100 is designed so that information corresponding to a predetermined operation is converted into an infrared signal and received by the light receiving unit 7 so that a variety of control contents (operation signals) implemented by the controller 1 can be inputted thereto from the remote controller 100. 
     How to input the operation signal by the remote controller 100 to the controller 1 and how the controller 1 is driven in response to the input operation signal will be described next with reference to the following specific examples (1) and (2). (1) To record a television program on channel 15 of the BS tuner 50e by the VTR-A 50b in normal speed during 9:00 p.m. to 10:54 p.m. on Monday. (i) When the viewer pushes a timer button 150 of the remote controller 100, the present situation of the timer in use is displayed on the picture screen of the television monitor 13. 
     As shown in FIG. 3, the television monitor 13 displays on the picture screen thereof a reserve number display area 500, a day display area 510, an A.M./P.M. separate display area 520, a start time display area 530, a difference of audio video apparatus and an operation condition display area 550 associated with the start time display area 530, an operation end time display area 540 and a difference of audio video apparatus and an operation condition display area 560 associated with the end time display area 540. 
     In this case, as the timer, a timer 60 incorporated in the VTR-A 50b or in the VTR-B 50c is utilized, and when the timer 60 is supplied with a set of operation start time and operation end time, a memory circuit of the timer 60 stores a reserve number indicating the order of the input set and the times of the set. 
     When the viewer pushes the timer button 150, the stored reserve number and the times of the set are read out from the memory circuit of the timer 60 by the microcomputer 3 and displayed, respectively, on the display areas 500, 530 and 540. (ii) When the viewer pushes a &#34;Monday&#34; button 210a of a day button pad 210, &#34;Monday&#34; is displayed on the display area 510. Also, when the viewer pushes a PM button 230 to select &#34;P.M.&#34;, &#34;PM&#34; is displayed on the display area 520. &#34;Day&#34; data and &#34;A.M&#34; &#34;P.M.&#34; data are stored in the memory circuit at the timer 60. (iii) The operation start time is input by pushing keys on a ten-digit key pad 160 and a button 180 in the order of &#34;9&#34;, &#34;:&#34;, &#34;0&#34; and &#34;0&#34; and the input of the operation start time is completed by pushing an enter key 200 (time input means). The operation end time is input in a similar fashion. (iv) When the viewer pushes a button 110a in an audio video apparatus selecting button key pad 110, the BS tuner 50e is selected, and the operation condition thereof (in this case, the channel selection) is input by pushing the keys in the ten-digit key pad 160 in the order of &#34;1&#34; and &#34;5&#34; and then the input of the operation condition is completed by pushing a button 190 (setting means). (v) The VTR-A 50b is selected by pushing a button 110b and the operation condition thereof (normal speed) is selected by pushing a speed button 120a of a function selecting button pad 120. Whereas, the operation condition thereof (recording) is set by finally pushing the enter button 200 (setting means) after a recording button (including both picture and sound) 120b was pushed, and the thus set data are displayed on the display area 550. (vi) The operation condition and so on in the operation end time are similarly set by pushing a stop button 120c, a rewind button 120d and the enter button 200 in that order after the VTR-A 50b was selected, and the thus set data are displayed on the display area 560. 
     At operation start time, the BS tuner 50e, the VTR-A 50b, and the audio video selector 50A are powered and the audio video selector 50A is controlled to supply an output signal from the BS tuner 50e to the VTR-A 50b. At operation end time, the power of the respective apparatus must be turned off (the VTR-A 50b is turned off after the rewinding operation) and these essential control procedures are automatically set by the microcomputer 3 when the operation conditions are set. 
     When the data of the reserve number 1 are set by the remote controller 100 as described above and when the timer time reaches the operation start time, the timer 60 derives a trigger signal (operation start command signal) and this trigger signal is supplied to the microcomputer 3. 
     Accordingly, the microcomputer 3 energizes the BS tuner 50e, the VTR-A 50b and the audio video selector 50A in accordance with the operation signals stored in the start buffer 9 and the processing data stored in the program ROM 5. 
     Then, the audio video selector 50A is switched so as to supply the output signal of the BS tuner 50e to the VTR-A 50b and the VTR-A 50b is energized to start the recording at normal speed. 
     When the timer time reaches the operation end time set, then a trigger signal (operation end command signal) from the timer 60 is supplied to the microcomputer 3 so that the microcomputer 3 turns off the powers of the BS tuner 50e and the audio video selector 50A and also stops and causes the VTR-A 50b to start the tape rewind operation. 
     At the completion of the tape rewind operation, the power of the VTR-A 50b is turned off and the processing for the reserve number 1 is finished. (2) To reproduce the compact disc from its third music loaded in the compact disc player 50i everyday during a period of 7:00 A.M. to 7:15 A.M. (i) When the listener pushes the timer button 150, data of the reserve number 2 is displayed. Then, when an &#34;everyday&#34; button 240 and the AM button 220 are pushed and when time data are input similarly as described above, respective data are displayed on the display areas 500, 510, 520, 530 and 540 as data of reserve number 2. (ii) Contents of the display area 550 are set and displayed by pushing a button 110c, pushing a music order button 120e twice (when this button 120e is not pushed, then the compact disc is reproduced from its first music), pushing a play button 120f and finally pushing the enter button 200, in that order. (iii) Contents of the display area 560 are set and displayed by pushing the button 110c, the stop button 120c and the enter button 200 in that order. 
     Contents or data of the reserve number 2 are set as described above. When timer time reaches the operation start time, then the trigger signal (operation start command signal) from the timer 60 is supplied to the microcomputer 3. 
     The microcomputer 3 energizes the compact disc player 50i and the audio amplifier selector 50B in response to the trigger signal supplied thereto in accordance with the operation signal and the processing procedure data stored respectively stored in the stop buffer 11 and the program ROM 5, and also switches the selector 50B so that the output signal of the compact disc player 50i is supplied to the selector 50B. 
     Then, the microcomputer 3 controls the compact disc player 50i so that the compact disc player 50i reproduces the third music from the compact disc. 
     When timer time reaches the operation end time set, the trigger signal (operation ending command signal) from the timer 60 is supplied to the microcomputer 3 so that the microcomputer 3 turns off the powers of the compact disc player 50i and the selector 50B, thereby the processing of the reserve number 2 being ended. 
     As described above, according to this embodiment, the timer 60 of the VTR-A 50b is utilized to control not only the VTR-A 50b but also other audio video apparatus such as the BS tuner 50e, the compact disc player 50i and so on or the selectors 50A and 50B. 
     Accordingly, the timer 60 can be utilized in the extended range and the audio video apparatus system 50 can be controlled by the controller 1 in a well-coordinated fashion. 
     Further, the controller 1 may be preferably incorporated within the audio video selector 50A, and the timer 60 may preferably be provided in the controller 1. 
     Furthermore, it is also preferable that the operation signal is input to the controller 1 by a panel switch or the like provided in the controller 1 instead of the remote commander 100. 
     As will be understood from the above description, in the audio video apparatus controller according to the present invention, the audio video apparatus are controlled to operate at desired time by utilizing the timer provided in the audio video apparatus. Accordingly, since audio video apparatus other than the audio video apparatus having the timer can be controlled by the same timer, the timer can be utilized in the extended range and also the audio video apparatus can be controlled in a well-coordinated fashion. 
     Having described the preferred embodiment of the invention with reference to the accompanying drawings, it is to be understood that the invention is not limited to that precise embodiment and that various changes and modifications thereof could be effected by one skilled in the art without departing from the spirit or scope of the novel concepts of the invention as defined in the appended claims.
