Abstract: <P>PROBLEM TO BE SOLVED: To provide an electronic apparatus and a control method of the electronic apparatus capable of correctly processing a desired broadcast program.  <P>SOLUTION: When a channel signal selectively received from a plurality of channels broadcasted is supplied from an external electronic apparatus, and a desired broadcast program is video-recorded by recording the above signal, a channel lock setting request is sent to the external electronic apparatus in ST2 in case that a recording start operation is performed in ST1. When completion of the channel lock is determined in ST3, video recording is started in ST4. When the video recording is completed in ST6, a channel lock release request is sent to the external electronic apparatus in ST7. In ST8, when the channel lock release is determined, the video recording is terminated. Because the external electronic apparatus is set to the channel lock state during the video recording, operation is determined invalid even when channel switching operation is performed on the external electronic apparatus. Thus, the desired program can be video-recorded correctly. Without any operation for setting or releasing the channel lock on the external electronic apparatus, setting or releasing the channel lock can be performed automatically.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
