Tuning data sharing apparatus and a method thereof for a television/video cassette tape recorder

A tuning data sharing apparatus for a television/video cassette tape recorder, comprising:

• a first memory for storing a plurality of tuning data;
• a first microcomputer for transferring the plurality of tuning data stored in the first memory, when a command to store the same tuning data is input thereto by the user;
• a second microcomputer for receiving the plurality of tuning data transferred from the first memory;
• a second memory for storing the plurality of tuning data transferred from the first memory under control of the second microprocessor so as to store the same plurality of tuning data in the first and second memories;
• tuner means for tuning a broadcasting signal using the plurality of tuning data stored in the first or second memory, said tuner means including a first and second tuner;
• said first tuner for tuning the broadcasting signal according to the plurality of tuning data stored in the first memory;
• a first audio/video signal processing circuit for processing the tuned signal;
• said second tuner for receiving the broadcasting signal bypassed through the first tuner to tune the broadcasting signal using the plurality of tuning data stored in the second memory;
• and
• a switch circuit for selecting between an output of the second tuner and an output of the first audio/video signal processing circuit.
