(Embodiment 1) Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

FIG. 1 is a block diagram of a device having the data storage device of the present invention as one component, FIG. 2 is a diagram showing an example of preset information, and FIG. 3 is a diagram showing an example of a reception schedule table. FIG. 4 is a flowchart of background reception.

In FIG. 1, the user sets the reception area or directly sets the channel by the operation unit 105, and the control unit 103 of FIG. 3 uses the preset information as shown in FIG. Such a reception schedule table is created and stored in the storage unit 104. The control unit 103 controls the tuner 101 and the digital data extraction unit 102 according to the procedure shown in FIG. 4 so that the text broadcast data and the data broadcast data are set to the channel of the tuner 101 shown in FIG. Storage unit 10 while sequentially switching
4 When the teletext and data broadcast data stored in the storage unit is used, the control unit 10
From 3 is displayed on the display unit 106.

The preset information of FIG. 2 is stored in the storage unit 1 of FIG.
04, and the priorities of the channels to be received are set for each region. For example, if the area is "Kobe", the first priority broadcasting station name is "NHK General" and the receiving channel is "28ch".
And the reception limit time is “1200 seconds”. Also,
In “Kobe”, “Asahi Broadcasting” of priority order 2 indicates that a data broadcast exists.

The reception schedule table of FIG. 3 shows an example in which the area selected by the user via the operation unit 105 of FIG. 1 is “Kobe”. The reception priority of “Kobe” in the preset information of FIG. 2 is extracted and stored as a reception schedule.

Based on the reception schedule table shown in FIG. 3, when the apparatus is capable of background reception, it receives and accumulates teletext data in order from the channel of the first priority. Further, in the case of a channel in which a data broadcast exists, reception and accumulation of data of the data broadcast are also performed.

FIG. 4 is a flowchart showing the operation of the control unit 10 shown in FIG.
3 shows a control procedure performed in Step 3. Initialization for starting reception from the channel of priority 1 is performed in ST1 of FIG. In ST2 of FIG. 4, it is determined whether the background reception of the text broadcast and the data broadcast is possible, and if possible, the process proceeds to ST3 of FIG. In ST3 of FIG. 4, it is determined whether the last priority of the reception schedule has been reached. If the last priority is exceeded, the process returns to ST1 in FIG. If it is within the last priority, the process proceeds to ST4 in FIG. In ST4 of FIG. 4, the receiving channel of the priority to be received is stored in the storage unit 104 of FIG.
From the reception schedule of FIG. 3 stored in
A channel is set in the tuner 101 of FIG. For example, in FIG. 3, when the priority is 1, the reception channel is 2

Set h.

In step ST5 of FIG. 4, it is determined whether or not data broadcasting exists in the selected priority channel based on the reception schedule of FIG. 3 stored in the storage unit 104 of FIG. When there is no data broadcast, S in FIG.
The control is shifted to T6, and when data broadcasting is present, the control is shifted to ST7 in FIG.

In ST6 of FIG. 4, reception of only the text broadcast is started, it is confirmed whether background reception is enabled in ST8 of FIG. 4, and control is transferred to ST10 of FIG. In ST10 of FIG. 4, text broadcast data is accumulated until all pages of the teletext are completely received within the reception limit time set in the reception schedule of FIG. For example, when the priority is 1, as shown in FIG.
The accumulation processing of text broadcast data for a maximum of 1200 seconds on 8 channels is performed. After the completion of the accumulation, the control is transferred to ST12 in FIG.

In ST7 of FIG. 4, reception of both the text broadcast and the data broadcast is started, and it is confirmed whether background reception is enabled in ST9 of FIG.
Control is transferred to ST11 of FIG. In ST11 of FIG. 4, it is not determined whether the teletext page has been completely received, and the data of the teletext and the data broadcast are accumulated until the reception limit time set in the reception schedule of FIG. 3 is reached. For example, if the priority is 2, according to FIG.
The accumulation processing for 6000 seconds is performed in the channel. After the completion of the accumulation, the control is transferred to ST12 in FIG.

In ST12 of FIG. 4, the priority is incremented by one, and the process returns to ST2 of FIG. 4 to start the accumulation processing of the reception channel of the new priority.

In many cases, this device has an effect that the data can be displayed immediately after the start of the text broadcast display, and that it can be compatible with the reception of the data broadcast.
