As described above, the television device with a memory function according to the present invention can select the channel selection mode and the category selection mode. In this embodiment, it is assumed that the category selection mode is selected. The recording mode of the category selection mode starts (step SP1). In step SP2, the remaining recordable capacity of the large-capacity memory held by the television device with a memory function is checked and stored. In step SP3, information such as a category is detected from the broadcast content transmitted from the broadcast station with an ID code and stored. In step SP4, it is confirmed whether or not the user has made a program reservation. If the user has made a program reservation, the program is preferentially accepted. If there is no user program reservation, the broadcast contents are classified for each category as they are.
[0038]
In step SP5, if a category area is selected and a broadcast station is specified, the category code is detected and stored. In step SP6, a FIFO operation is performed in which old broadcast contents are sequentially deleted and new broadcast contents are recorded. In step SP7, the remaining capacity of the memory capacity allocated to the category area is checked.
[0039]
If there is a margin in the recording capacity of the category area, the process proceeds to step SP8. If there is no margin in the recording capacity, the process returns to step SP6 to repeat the FIFO operation to update the broadcast contents. In step SP8, if the ID code such as the broadcast time is checked and matched, the process proceeds to step SP9 and the recording is started continuously. If there is no match, the process returns to step SP8 again to match the broadcast time. . In step SP10, the series of recording mode operations ends.
[0040]
Next, the operation in the playback mode will be described with reference to FIG. When the user selects a reproduction mode and starts (step SP11), in step SP12, a menu screen showing each category area shown as an example in FIG. 2B is displayed based on the control program in the ROM / RAM. In step SP13, a desired category is selected (recorded broadcast content) from the menu screen. If NO, the process returns to step SP12, and if YES, the process proceeds to step SP14. In step SP14, the menu screen display is erased, and at the same time, a playback mode window as shown in FIG. 6A is displayed. At this time, a predetermined time for normal reproduction is displayed on the display unit as “reproduction time is 60 minutes”.
[0041]
Moving to step SP15, when the user selects a desired category area by operating the operation unit of the remote control unit, a pointer (instruction mark) 22 appears on the display unit of FIG. 6A, and the operation unit is displayed. The normal reproduction mode or the high-speed reproduction mode is selected by moving up and down and clicking (enter). Here, when the normal reproduction mode is selected, the process proceeds to step SP16, and other functions are selected. If YES, the process moves to step SP17, where the selected function is processed and displayed on the display unit. If the selection of other functions is NO, the process returns to the start position.
[0042]
On the other hand, when the high-speed playback mode is selected in step SP15, the process proceeds to step SP18, and a playback time designation window is displayed as shown in FIG. 6B. In step SP19, the operation unit of the remote control unit is operated on the display unit to move the poiter 22 to select a desired time, and the playback time is selected by moving the operation unit up and down and clicking. In step SP20, a playback time window as shown in FIG. 6C is displayed, and an arbitrary playback time is realized by selecting a combination of the playback times shown in the drawing.
[0043]
In step SP21, it is prompted to determine whether or not to start digest playback with the displayed playback time, and in case of cancellation, the process returns to the playback time window in step SP20. If start is selected, the process proceeds to step SP22, where the ID of the recorded content added during recording is checked and read out. At step SP23, the recorded contents of the large-capacity memory are started to be reproduced at a desired reproduction speed, and are displayed on the display unit at step SP24. As described above, the series of high-speed playback mode operations ends (step SP25).
[0044]
According to the embodiments of the present invention described above, even when a multimedia-capable television device with a memory function is likely to be adopted in the future, a form incorporating various large-capacity memories will be broadcast. Since a desired broadcast program can be recorded from a vast number of broadcast programs and a desired playback time can be freely set and viewed, busy users can be freed from complicated operations such as VTR. Thus, it is possible to obtain the latest information easily and within a desired time. Also, the method for selecting the playback time is easy.
[0045]
In the above embodiment, the method of specifying the playback time has been described in the case of setting in the screen dialogue format. However, the desired playback time may be set directly with the numeric keypad, and of course, like a normal VTR. A manual operation for selecting and recording desired program software is also possible. Furthermore, it goes without saying that the present invention can be developed in various forms without being limited to the above-described embodiment.
[0046]
