1. a digital device (200), being used to reset is stored in the compressed digital video representation signal on the recording medium, and said digital device comprises:

  • Processing unit (251,220) is used to handle the said digital video representation signal that is stored on the recording medium, to produce the compressed digital video signals stream (221) of an output, to be decoded by a decoder (117);

    Status message generator (205/270) is used to produce a message data signal (272) of indicating the working method of said digital device (200);

    Display message combiner (275);

    Has the first input end that is connected with said message data signal (272);

    With second input that is used for receiving the vision signal (102) of decoding from said decoder (117);

    So that the vision signal (102) of said message data signal and said decoding is combined, on video-frequency monitor, to show synchronously;

    AndDelay element;

    Be connected to said status message generator (205/270);

    Be used to postpone the generation or the transmission of said message data signal (272);

    Wherein said delay element provides delay, to compensate the decode time of said decoder, makes said message data signal synchronous with the vision signal of the said decoding that is used for showing synchronously thus.
