The program deletion priority standard is a combination of the number of times of reproduction and the broadcast start date and time. In other words, a program may be “played once”,
It is classified into any one of the groups of “reproduction twice or more”, “no reproduction”, and “reserved”.
Times ”,“ 2 or more times of reproduction ”,“ no reproduction ”, and“ reserved ”. In addition, within the same group, a program with an earlier broadcast start date and time is given a higher deletion priority. However, a program in which the user specifies whether or not erasing is “erasable” is not given an erasure priority. Therefore, the program “baseball ab vs cd12” is classified into the “reservation” group, but the designation of erasure is “non-erasable”, so the program “baseball ab vs cd1” is specified.
The recording reservation of "2" will not be canceled without the user's instruction to cancel the recording.

The program erasure priority criterion in the second embodiment corresponds to the predetermined criterion of the present invention in combination with the above-mentioned designation of erasability by the user.
