When the program recording setting device sets the recording of a program, the management device predicts whether there is a shortage of vacant space in the recording medium. This is done when the recording device writes the contents of the program to the recording medium by referring to program management information. To provide vacant space in the recording medium, the management device decides programs to be erased according to predetermined criteria which include an erasure possibility set prior to erasure of the programs to be erased.
The medium control part 60 inputs a command from the micro controller 240 wherein a clock and graphics function are built in and erases the data containing the contents of the program �It Will be Sunny Tomorrow (sixth)� and the data containing the contents of the program �It Will be Sunny Tomorrow (seventh).�
The main tuner 10 receives the electric wave sent out from the broadcasting station (not shown) from the antenna 1 at 21:00 on Aug. 12, 1999 and extracts the data containing the contents of the program �Total Solar Eclipse (second)� so as to carry out a signal output to the image/speech sound encoding processing part 30. The image/speech sound encoding processing part 30 encodes a signal inputted from the main tuner 10 and carries out a signal output to the medium control part 60. The medium control part 60 inputs a signal from the image/speech sound encoding processing part 30 and starts the writing in of the data containing the contents of the program �Total Solar Eclipse (second)� to the recording medium 261.
The micro controller 40 wherein a clock and graphics function are built in recognizes that sufficient vacant space does not exist in the recording medium 61 at the time when the writing in of the data containing the contents of the program �Total Solar Eclipse (second)� of which the recording time is 2 hours is carried out (that is to say, at 21:00 on Aug. 13, 1999), because the maximum recording time of the recording medium 61 is 12 hours and the total recording time of the programs of which the program recording conditions are �recorded� at 21:00 on Aug. 13, 1999 is 12 hours. Accordingly, the microcontroller 40 wherein a clock and graphics function are built in judges that the data containing the contents of the program which has been recorded at 21:00 on Aug. 13, 1999 must be erased in order to carry out the recording of the program �Total Solar Eclipse (second)� according to the record indication by the recording setter A.
The micro controller 40 wherein a clock and graphics function are built in accepts the recording of the program group �Total Solar Eclipse� based on the above described judgment as the record indication by the recording setter A and updates the program management information as shown in FIG. 3 into the program management information as shown in FIG. 4. Here, FIG. 4 is a list of updated program management information at 20:30 on Aug. 12, 1999 which is described in the embodiments of the present invention, which is different from FIG. 3 in the point that information concerning the program group �Total Solar Eclipse,� is written in. Here, the program �Professional Baseball Avs. B (the eighth game)� (which is noted as 1999/0810/18:00in FIG. 4) and the program �News Seven (August 11)� (which is noted as 1999/0811/07:00 in FIG. 4) which are the programs intended to be erased have x marks attached.
The program erasure priority criterion is the combination of the playback number and the broadcast start date and time. That is to say, the programs are categorized into any of the groups: �playback once,� �playback twice or more,� �no playback� and �set for recording� according to the playback number and the recording condition while the erasure priority becomes higher in the order of �playback one,� �playback twice or more,� �no playback� and �set for recording. In addition, within the same group the earlier the broadcast start date and time the higher the erasure priority given to the program. Here, no erasure priority is given to a program of which the above described user indication of erasure possibility is �non-erasable.� Accordingly, though the problem �Baseball ab vs. cd 12� is categorized in the group �set for recording,� the setting for the recording of the program �Baseball ab vs. cd 12� is not cancelled without the indication of cancellation of the setting for the recording by the user since the indication of the erasure possibility is set as �non-erasable.�
Here, the program management table consists of seven items: present time, broadcast start date and time, program title, program recording capacity, erasure priority (including indication of a program for which �non-erasable� is designated) erasure plan and check box for manual setting of erasure/recording release. In addition, in the lower part of the program management table, a button which has a �return� symbol to call back the immediately preceding screen and a button which has a �release� symbol for confirming the manual erasure/recording release through the GUI utilization are displayed.
The speaker 92 inputs the command from the micro controller 40 wherein a clock and graphics function are built in and outputs the speech sound indication �setting for recording is complete.�
