    Hello.
    Can someone gives any idea about the implementation of a basic Finite State Machine model for a VCD / DVD player? My idea would be something like this :

    Code:
    State OFF ---> Power ---> State ON / TRAY CLOSE
    State ON / TRAY CLOSE ---> Power ---> State OFF
    
    State ON / TRAY CLOSE ---> Eject ---> State TRAY OPEN
    State TRAY OPEN ---> Eject ---> State ON / TRAY CLOSE
    
    State ON ---> Play ---> State PLAYING
    
    State PLAYING ---> Pause ---> State PAUSED
    State PLAYING ---> Forward ---> State FORWARD PLAY
    State PLAYING ---> Backward ---> State BACKWARD PLAY
    
    State PAUSED ---> Play ---> State PLAYING
    State FORWARD PLAY ---> Play ---> State PLAYING
    State BACKWARD PLAY ---> Play ---> State PLAYING
    
    State PAUSED ---> Forward ---> State FORWARD PLAY
    State PAUSED ---> Backward ---> State BACKWARD PLAY
    
    State PLAYING ---> Stop ---> State ON
    State PAUSED ---> Stop ---> State ON
    State FORWARD PLAY ---> Stop ---> State ON
    State BACKWARD PLAY ---> Stop ---> State ON
    
    State PLAYING ---> Power ---> State OFF
    State PAUSED ---> Power ---> State OFF
    State FORWARD PLAY ---> Power ---> State OFF
    State BACKWARD PLAY ---> Power ---> State OFF
    I'm sorry if I'm quiet dumb at this, this might be the worst form to represent an FSM model, but it's the best way I can think of now. I would appreciate any suggestion, improvement or correction.
