[0071] Embodiments of the cable TV system of the present invention are described with reference to the drawings. figure 2 It is a block diagram showing the relationship of each device constituting the wired system. The wired system includes a headend 101 and three terminal devices, namely terminal device A111, terminal device B112 and terminal device C113. In this embodiment, three terminal devices are connected to one headend. However, the invention can be implemented with any number of terminal devices connected to the headend.
[0072] The front end 101 transmits broadcast signals such as video, audio, and data to a plurality of terminal devices, and receives data transmitted from each terminal device. To achieve this, the frequency band is divided for data transmission between the front end 101 and the terminal device A111, the terminal device B112 and the terminal device C113. image 3 is a table showing examples of divided frequency bands. There are roughly two freq...

[0169] In the first embodiment, in the case where a situation in which descrambling cannot be performed occurs during recording, recording is terminated. However, when the situation in which descrambling cannot be performed lasts only for a short period of time and scrambling becomes possible again immediately, the period of time of the program recorded in the scrambled state is also short. Therefore, it may be more advantageous for the user to continue recording the program.
[0170] Thus, in this embodiment, recording is continued even when a situation in which descrambling cannot be performed occurs during recording. However, in the case of writing the program recorded in the auxiliary storage unit 510 into the medium inserted into the medium writing unit 516, whether to perform writing is confirmed by the user.
[0171] Figure 24 A flow chart of the recording function in this embodiment is shown in the case where a situation in which descrambling cannot be performed occ...

[0186] In the second embodiment described above, when problematic recording data is written on the recording medium, the user is notified of problem information. In this embodiment, when problematic recorded data is reproduced, the user is notified of problem information. In this example, a terminal device (digital broadcast recording device) includes a reproducing unit (not shown in the figure) that reproduces a recording subject program stored in an auxiliary storage unit.
[0187] Figure 31 is a diagram showing an example of question information notified to the user according to the present embodiment.
[0188] exist Figure 31 Among them, 609 means Figure 7 The display shown in 609. Display 1710 depicts the Figure 28 Create the problem information corresponding to the management information indicated in row 1708. Here, as an example, "Movie A" is described as the recording subject program corresponding to row 1708 . Time 2701a indicates the time at which the ques...
