Recording and reproducing apparatus

Abstract

A recording and reproducing apparatus capable of recording and reproducing the signals of both a digital broadcast system and an analog broadcast system is disclosed. By utilizing the existing configuration efficiently, the cost increase due to the system change is minimized. Both the digital broadcast system and the analog broadcast system are connected to a connector to receive both digital and analog broadcast signals. The analog broadcast signal input through the connector is recorded in a digital broadcast signal recording unit of the digital broadcast system under the control of the control unit included in the digital broadcast system.

1 . A recording and reproducing apparatus comprising:
 an analog broadcast unit to receive and reproduce an analog broadcast signal; and   a digital broadcast unit to receive and reproduce a digital broadcast signal;   wherein said digital broadcast unit includes   a digital recording unit to record the digital broadcast signal received,   an input unit to input selected one of a control signal generated in said analog broadcast unit for controlling the recording operation into said digital recording unit and an analog broadcast signal received by said analog broadcast unit, and   a control unit to control the recording operation into said digital recording unit; and   wherein said control unit performs the control operation in such a manner that said analog broadcast signal input through said input unit is recorded in said digital recording unit based on the control signal input from said input unit.

       3 . A recording and reproducing apparatus comprising:
 an analog broadcast unit to receive and reproduce an analog broadcast signal;   a digital broadcast unit to receive and reproduce a digital broadcast signal; and   a connector to connect said analog broadcast unit and said digital broadcast unit to each other to exchange data;   wherein said analog broadcast unit includes a first recording unit to record the received analog broadcast signal;   wherein said digital broadcast unit includes a second recording unit to record the received digital broadcast signal and a control unit to control the recording operation of said digital recording unit based on the control signal generated by said analog broadcast unit and input through said connector; and   wherein said control unit performs the control operation in such a manner that said analog broadcast signal input through said connector is recorded in said first recording unit, while said analog broadcast signal input through said connector is recorded in said second recording unit based on the control signal input through said connector.   
   
   
       4 . A recording and reproducing apparatus according to  claim 1 , comprising a reproducing unit to reproduce the data recorded in selected one of said digital recording unit and selected one of said first recording unit and said second recording unit. 
   
   
       5 . A recording and reproducing apparatus according to  claim 1 ,
 wherein said digital broadcast unit includes an encryption unit to encrypt selected one of said digital broadcast signal and said analog broadcast signal input through said connector, before being recorded in selected one of said digital recording unit and said second recording unit.   
   
   
       6 . A recording and reproducing apparatus according to  claim 5 ,
 wherein said digital broadcast unit includes a decoding unit to decode the data encrypted by said encryption unit and recorded in selected one of said digital recording unit and said second recording unit.   
   
   
       7 . (canceled) 
   
   
       8 . A recording and reproducing apparatus according to  claim 1 , comprising a communication interface unit to exchange the signals indicating the operating conditions of said analog broadcast unit and said digital broadcast unit. 
   
   
       9 . A recording and reproducing apparatus according to  claim 3 ,
 wherein said control unit performs the control operation in such a manner that the data recorded in said first recording unit is recorded in said second recording unit.
