  • an analog video tape recorder has been used to record and playback images and sounds. That is, the video tape recorder receives a TV signal and stores the TV signal in an analog video tape, thereby enabling users to record TV programs. Such recording or taping can be accomplished either while watching the TV program or by programming a desired time and station so that the television need not be playing the TV program being recorded.
  • Such an analog video tape recorder records TV broadcast signals in a VHS manner having a resolution less than that originally supported by the TV broadcast signals of the NTSC system (supporting 720 pixels x 240 lines x 60 field and 525 scan lines). That is, the resolution is one-third that obtained with the TV broadcast signals. Accordingly, when the recorded TV program is played back, the reproduced images and sounds are inferior to the original resolution supported by TV broadcast signals. This problem also occurs in the case of the PAL and SEC AM systems. When the user intends to record TV program by programming the tape recorder, typically the desired time and channel is set by the user. There is also a method in which a bar code assigned to each program is used to program the recorder.

Then, the controller 8 determines if the selected data group is a protected data group (S4_2).
