Alternatively, a display apparatus  100 , which has the display unit  11  may be provided as an additional apparatus.  
      In another exemplary embodiment of the present invention, a broadcasting signal recording/playing system may comprise a broadcasting signal recording/playing apparatus  500  which has a storage unit  41  and a playing unit  31 , and a broadcasting signal tuning apparatus  200  which has a broadcasting signal tuning unit  21  and a recording/playing controller  25 . Here, one of the broadcasting signal recording/playing apparatus  500  and the broadcasting signal tuning apparatus  200  may further comprise a display unit  11 . Alternatively, a display apparatus  100 , which has the display unit  11  may be provided as an additional apparatus.  
      The broadcasting signal recording/playing system may be variously provided as long as the recording/playing controller  25  is disposed in the same apparatus together with the broadcasting signal tuning unit  21 , and controls other apparatuses.  
       FIG. 3  is a control flowchart of the broadcasting signal recording/playing system which comprises a storage apparatus  400 , a playing apparatus  300 , the broadcasting signal tuning apparatus  200  and the display apparatus  100 . Alternatively, the broadcasting signal recording/playing system may vary.  
      If the broadcasting signal is received (S 11 ), the broadcasting signal tuning apparatus  200  tunes the broadcasting signal into a predetermined channel according to the predetermined tuning control signal. If the recording signal is input through the user selection unit  15  (S 13 ), the recording/playing controller  25  of the broadcasting signal tuning apparatus  200  outputs the broadcasting signal tuned by the broadcasting signal tuning unit  21 , to the storage apparatus  400  (S 15 ). Hereinafter, the recording signal comprises a pause signal as an example of the exemplary embodiment of the present invention.  
      Here, the recording/playing controller  25  may control the storage apparatus  400  to store the broadcasting signal therein. Then, the storage unit  41  of the storage apparatus  400  stores the broadcasting signal from the point of time if the pause signal is input (S 17 ).  
      If the predetermined playing signal is input (S 19 ) and the storage apparatus  400  stores the broadcasting signal therein (S 21 ), the recording/playing controller  25  controls the broadcasting signal stored from the time if the pause signal is input, to be output to the playing apparatus  300  from the storage apparatus  400 .  
      As the storage apparatus  400  supplies the broadcasting signal stored therein from the point of time if the pause signal is input, to the broadcasting signal tuning apparatus  200 , the broadcasting signal tuning apparatus  200  outputs the broadcasting signal stored in the storage apparatus  400  to the playing apparatus  300  (S 43 ). If the broadcasting signal is input, the playing unit  31  processes the input broadcasting signal to be played by the display apparatus  100  (S 45 ), and outputs the broadcasting signal to the display unit  11  of the display apparatus  100 . Then, the display unit  11  displays an image thereon based on the broadcasting signal (S 47 ). If the predetermined playing signal is input (S 19 ) and if the storage apparatus  400  stores the broadcasting signal therein (S 21 ), the recording/playing controller  25  outputs the broadcasting signal and a storage control signal to store the broadcasting signal, to the storage apparatus  400  (S 49 ). Then, the storage unit  41  of the storage apparatus  400  stores the broadcasting signal therein (S 49 ). Here, the operation S 48  in which the recording/playing controller  25  outputs the storage control signal to the storage apparatus  400  may be changed with the operation S 43  in which the broadcasting signal is output to the playing apparatus  300 . Alternatively, the operations  48  and  43  may be simultaneously performed. Accordingly, the operation  49  in which the broadcasting signal is stored in the storage apparatus  400  may be changed with the operation S 47  in which the playing apparatus  300  processes the broadcasting signal to be played and the display unit  100  displays the image thereon.  
      If the predetermined playing signal is input (S 19 ), and if the storage apparatus  400  does not store the broadcasting signal therein (S 21 ), the recording/playing controller  25  outputs the broadcasting signal input through the broadcasting signal tuning unit  21 , to the playing apparatus  300  (S 23 ). The playing unit  31  processes the input broadcasting signal to be played by the display apparatus  100  (S 25 ), and then outputs it to the display apparatus  100 . The display unit  11  of the display apparatus  100  displays the image thereon based on the broadcasting signal (S 27 ).
