Description

  The present invention relates to a data processing apparatus that stores and reproduces data, a control method thereof, a control program, and a storage medium.

  Conventionally, as a method of recording broadcast contents such as radio broadcasts and television broadcasts, a program being broadcast, such as a cassette tape or MD (Mini Disk) in the case of radio broadcasts, a video tape in the case of television broadcasts, etc. The method of recording on a recording medium has been mainstream. In recent years, digital devices using a recording medium such as an IC memory card, a non-volatile memory, and a hard disk have appeared, and some have a function of recording a radio broadcast or a television broadcast. Even in a vehicle data processing apparatus such as a vehicle digital audio which is a kind of digital equipment, it is possible to record radio broadcasts, television broadcasts, and the like on hard disks and IC memory cards.

  Some of such in-vehicle digital devices can display the playback content on a display screen. As a method, for example, CD (Compact Disk) or the like, information from a disk or database such as CD-TEXT is used. A method using a search system based on TOC information such as (CDDB) has been performed. Thus, information such as the album name and track name of the CD to be reproduced is displayed, and the user can visually grasp the CD information and search for the track to be selected.

In broadcast programs, an electronic program guide (EPG) or the like can be used to automatically display a program name or the like at the time of reproduction, and the electronic program guide is acquired from broadcast radio waves or the Internet. For example, in a radio broadcast, a listener of a radio broadcast can record the music by using a recording device such as an MD recorder when the favorite music flows. On the other hand, when a broadcast tag including the name of the broadcast station and the broadcast time of the recorded music is transmitted from the user terminal so that the title and artist of the recorded music can be known, the broadcast tag is associated with the broadcast tag. There has been proposed a database server that transmits identification information describing a title and an artist recorded to a user terminal (see, for example, Patent Document 1).

  By the way, in the above conventional technique, the electronic program guide corresponding to the recorded content is acquired based on the frequency of the broadcast radio wave, the broadcast station name, or the broadcast time. However, even if broadcast radio waves have the same frequency (channel), broadcast stations and programs may differ depending on the region. For this reason, the electronic program guide can be used without any problem if the installation location is always fixed in the same area, but it is not considered to be used for a moving device such as an in-vehicle data processing device. In other words, the recorded contents and the electronic program guide do not always correspond correctly only with the frequency of the broadcast radio wave and the broadcast time. Therefore, when recording a broadcast with an in-vehicle data processing device, if the reception area is not set manually each time it moves, the recorded time and the electronic program guide will not correspond correctly when the recorded content is played back. I can only do it.

First, main controller 11 determines whether or not the current position has been specified based on the information acquired from position detector 2 (step 1).
In step S1, if the main control device 11 determines that the current position could not be specified (step S1: NO), the user manually operates the operating area 3 to manually specify the broadcast area to which the current position belongs (step S1). S2), the process proceeds to step S3.

  On the other hand, if the main control device 11 determines in step S1 that the current position has been identified (step S1: YES), the position data is checked against the list of broadcast stations (transmitting stations) stored in the database of the recording device 1. The receivable broadcast stations are listed, and the receivable broadcast stations at the current position are displayed on the display unit 10 (step S3). Here, in order to extract a receivable broadcast station based on position data, it is determined by determining whether or not receivable is possible based on the distance from the current position to the broadcast station, transmission output, and the like.

  In step S2, if the area to which the current position belongs is manually specified, the receivable broadcast stations in the specified area are displayed on the display unit 10 without being based on the position data.

  Next, the user operates the operation unit 3 to select a broadcast station that should receive broadcast radio waves from receivable broadcast stations displayed on the display unit 10 (step S4).

  Then, main controller 11 determines whether or not the broadcast signal recording operation is started by the user operating operation unit 3 (step S5).

  In step S5, when determining that the broadcast signal recording operation has not been started (step S5: NO), main controller 11 is in a standby state until it is determined that the broadcast signal recording operation has been started.

  On the other hand, when the main control device 11 determines in step S5 that the recording operation of the broadcast signal has started (step S5: YES), the main control device 11 broadcasts based on the time data included in the GPS data acquired from the position detection unit 2. The recording start time when the signal recording operation is started is stored in the storage device 12 (step S6).

  Next, main controller 11 stores information on the currently received broadcasting station selected in step S4 in storage device 12 as receiving station information (reception frequency information) (step S7).

  Then, main controller 11 determines whether or not the broadcast signal recording operation is finished (step S8).

  In step S8, when determining that the broadcast signal recording operation has not been completed (step S8: NO), main controller 11 repeats the process of step S8).

  On the other hand, if the main control device 11 determines in step S8 that the recording operation of the broadcast signal has been completed (step S8: YES), the main control device 11 broadcasts based on the time data included in the GPS data acquired from the position detection unit 2.

Is determined (step S24). Here, the fact that there are a plurality of corresponding programs means that there are a plurality of programs between the recording start time and the recording end time stored in the program verification data.

  In step S24, when the main control device 11 determines that there are a plurality of programs corresponding to the broadcast data corresponding to the program verification data in the electronic program guide (step S24: YES), a plurality of corresponding program information (for example, broadcast) Time and program name) are acquired as program candidate information (step S27), and the process proceeds to step S29.

  On the other hand, if the main controller 11 determines in step S24 that there is one program corresponding to the broadcast data corresponding to the program verification data in the electronic program guide (step S24: NO), the corresponding program is It is determined that the program is recorded as broadcast data corresponding to the program verification data, and the program name of the corresponding program is determined as the program name of the program recorded as broadcast data (step S26).

  Next, main controller 11 obtains program information corresponding to the program having the program name determined in step S26 from the database (step S28), and determines whether or not the collation process is completed (step S29). Here, whether or not the collation process is completed is determined by whether or not there is any other program collation data.

  In step S29, when determining that there is other program verification data and the verification process has not ended (step S29: NO), main controller 11 repeats the series of processes from step S22.

  On the other hand, when the main control device 11 determines in step S29 that there is no other program verification data and the verification processing has ended (step S29: YES), the series of processing ends.

  In step S24, when the main controller 11 determines that there are a plurality of programs corresponding to the broadcast data corresponding to the program verification data in the electronic program guide, one of the plurality of corresponding program information is automatically set. It is possible to set in advance so that the user can select program information to be displayed on the display unit 10, or display program information options on the display unit 10.

In addition, when a plurality of programs are recorded continuously at a time, the program start time and the like can be obtained based on the program information. You can search, divide, delete, and edit the beginning of a file in which data is recorded.
Further, by comparing the recording start time and the recording end time with the program broadcast time of the program information acquired from the database, whether the broadcast data is a recorded program or a part of the program is recorded. It is also possible to determine whether or not and display that fact on the display unit 10.

  According to the present embodiment, even if the broadcasting station receives different broadcast radio waves depending on the region even though the same frequency is transmitted, the broadcasting station can be identified and broadcast program information can be acquired. Therefore, when the broadcast content based on the broadcast signal acquired from the broadcast radio wave is recorded, the program information corresponding to the recorded broadcast content can be correctly acquired.

  As mentioned above, although this invention was demonstrated based on one Embodiment, this invention is not limited to this. For example, in the embodiment, the main control device 11 determines the recording start time and the recording end time based on the time data stored in the GPS data acquired from the position detection unit 2, but the present invention is not limited to this.
