FIG. 1 shows an example of commercial sponsor information superimposed on a signal vertical blanking interval of a commercial section in a television broadcast program. This sponsor information 100 is schematically given priority information 101 indicating priority for each commercial. , The commercial appeal method 102. The priority information 101 has five levels, and the appeal method 102 for each level is:
Priority = 1: Sponsor name (bold), detailed information, link information to the homepage (URL)
Priority = 2: Sponsor name, detailed information, link information to the homepage (URL)
Priority = 3: Sponsor name, homepage link information (URL)
Priority = 4: Sponsor name, detailed information Priority = 5: Sponsor name. That is, based on the sponsor information 100, the transmission side superimposes the sponsor priority information 101 together with the information 102 such as the sponsor name and URL in the signal vertical blanking interval of the commercial section of the television program.

  FIG. 2 shows a recording / reproducing device 11 according to an embodiment of the present invention. The broadcast signal is taken into the tuner 4 in the recording / reproducing device 11 through the antenna 3, and when a specific broadcast is selected by the user's instruction, the tuner 4 selects the television signal to which the priority information 101 is added. The decoder information of the decoder / encoder 5 is acquired by the decoder 5 and the sponsor information 100 including the priority information 101 and the video / audio data are acquired. The video / audio data is converted into a form to be recorded on the recording medium 9 by the encoder unit of the decoder / encoder unit 5, and is recorded on the recording medium 9 through the CPU 6 and the pickup 8. On the other hand, the sponsor information 100 is temporarily stored in the memory 7 through the CPU 6, and is additionally stored in the memory 7 every time the sponsor information 100 is acquired until the end of the recording operation (memory 7a, 7b, 7c in FIG. 2). Upon completion of the recording operation, the sponsor information 100 stored in the memory 7 is recorded on the recording medium 9 via the CPU 6 and the pickup 8.

  FIG. 3 shows an example of logical recording positions on the recording medium 9. In the navigation data area 14, navigation data created at the time of encoding to reproduce the video / audio data recorded on the recording medium 9 is recorded, and the sponsor information 100 is also recorded in this area 14. Reference numeral 15 denotes an area for recording video / audio data of the program. FIG. 4 shows an example of the saved sponsor information 16 recorded in the navigation data area 14, and the saved sponsor information 16 is recorded in order of priority.

  FIG. 5 shows a menu screen 17-1 that is output and displayed on an external monitor 12 when a program recorded in the recording medium 9 is reproduced. The menu screen 17-1 shows a thumbnail representing the recorded program. 18-1 to 18-6 are displayed. FIG. 6 shows a screen 17-2 output when the thumbnail 18-1 is selected on the menu screen 17-1 of FIG. 5. On the screen 17-2, an icon 18-1 and this screen are displayed. A message 19 explaining 17-2, detailed information 20-1 to 20-4 arranged in order of priority for each saved sponsor information 16 recorded in the navigation data area 14 of FIG. 4, and a reproduction start button 21 are displayed. .
