In a digital broadcast receiver with a recording function equipped with one tuner, there is a restriction that there is only one program that can be viewed at the same time. By eliminating the simultaneous reservation, only one program can be reserved for recording during the same time period. However, for mobile devices that have digital broadcast reception functions for different broadcasting systems, such as broadcasting in the VHF band and broadcasting in the UHF band, which broadcasting system is received favorably depending on the state of the receiver at the scheduled recording time. If the program to be recorded is determined at the time of recording reservation, the program selected in advance cannot be received at the time of recording, and another broadcasting system that does not record due to duplication of recording can be received. Things happen.
In the above-mentioned patent document, when the reception status of each broadcast with overlapping reservations differs depending on the situation where the receiver is placed at the reserved recording start time, a technique corresponding to the difference is not disclosed.

  In view of such circumstances, the present invention is intended to provide a broadcast receiving apparatus with a recording function and a program capable of selecting a better reception state when recording reservations overlap.

The present invention provides a broadcast receiving apparatus having a function of receiving and recording a broadcast program,

  The TS data processing unit 15 includes a one-segment recording data processing unit 16 and an ISDB-Tmm stored broadcast data processing unit 17. Under the control of the control unit 20, the one-seg recording data processing unit 16 extracts a recording packet for one-seg broadcasting from the TS data and records it in the recording unit 19. The ISDB-Tmm stored broadcast data processing unit 17 extracts a stored broadcast packet of ISDB-Tmm broadcast from the TS data under the control of the control unit 20, reconstructs the stored content, and records it in the recording unit 19.

An embodiment in which the present invention is applied to a mobile phone equipped with ISDB-Tmm (VHF band) and one-segment (UHF band) reception functions will be described below.
As shown in FIG. 2, program A (broadcast time 19:00:00 to 20:00) of storage type broadcast (file casting broadcast) of ISDB-Tmm broadcast station 2 and program B (broadcast time of one-segment broadcast station 3) 19: 30-20: 30), recording reservations overlap at 19: 30-20: 00. In this mobile phone, the overlapping reservation as shown in FIG. 2 is allowed at the time of reservation.

  The operation of the mobile phone according to the first embodiment in which the overlapping recording reservation is made will be described with reference to the flowchart of FIG.

The control unit 20 acquires the current time from the time management unit 21 (step S1). With reference to the program reservation list in the reservation management table (see FIG. 2) of the reservation management unit 22, if it is one minute before the recording reservation start time (step S2; Yes), another reservation is made before the end of the reserved program. It is confirmed whether there is (step S3). If it is not one minute before the start time reserved for recording (step S2; No), the process returns to step S1.
For example, according to the reservation management table of FIG. 2, since there is a recording reservation for program A from 19:00, when the control unit 20 reaches 18:59, is there another overlapping reservation during the recording time of program A? Confirm.

  If there is no overlap in recording reservation time (step S3; No), normal recording processing is performed (step S16). This is a process of starting the tuner 10 seconds before the reservation start time, selecting a desired broadcast station, and starting recording on the recording unit 19 at the reservation start time.

  If there is an overlap in the recording reservation time (step S3; Yes), the user is notified to put the mobile phone 10 in the most sensitive state (step S4). For example, in the case of receiving a VHF broadcast wave, when it is necessary to attach an earphone antenna, the display unit 23 performs a display for prompting the user to perform such an operation.

The control unit 20 activates the tuner 14 (step S5).
In step S6, processing for acquiring the reception status of the program that has been reserved for overlapping is performed (steps S7 to S10). The program A and the program B in FIG. 2 that have been reserved for recording overlap at 19:30 to 20:00. Therefore, in step S6, the reception status of the broadcasting stations 2 and 3 is acquired.

The antenna switching unit 13 causes the antenna to select the VHF antenna 11 and selects the broadcast station 2 (step S7). The control unit 20 acquires information indicating the reception state such as BER and CN from the tuner 14 and temporarily stores the information in the recording unit 19 (step S8).
Next, the control unit 20 causes the antenna switching unit 13 to switch the antenna to the UHF antenna 12 and selects the broadcast station 3 (step S9). The control unit 20 acquires information indicating the reception state such as BER and CN from the tuner 14 and temporarily stores it in the recording unit 19 (step S10).
In step S6, the information indicating the reception state may be obtained by periodically repeating antenna switching for a certain period of time and obtaining the average value as the reception state.

  In step S6, the control unit 20 compares the reception states of the broadcasting stations 2 and 3 stored in the recording unit 19, and determines which reception state is better (step S11).

  As a result of the comparison, if the reception state of the broadcasting station 2 is better, the control unit 20 causes the antenna switching unit 13 to switch the antenna to the VHF antenna 11 (step S12), and performs the recording process of the program A of the broadcasting station 2. (Step S13).

  As a result of the comparison, if the reception state of the broadcasting station 3 is better, since the program B starts at 17:30, the control unit 20 turns off the tuner 14 once and turns the tuner 14 again 10 seconds before the recording start time. Activation, tuning to the broadcasting station 3, switching the antenna to the UHF antenna 12 (step S14), and recording the program B in the recording unit 19 (step S15).

  In this way, even when recording reservations are duplicated, the program to be recorded at the time of reservation is not selected, and the mobile station program that can be stably received at the recording start time is selected and recorded. Therefore, the risk that the recording becomes impossible can be reduced.

If the broadcast is being viewed before the reservation start time, the tuner 14 has already been activated, so the above-described tuner activation and tuner OFF processing is omitted. In addition, the time of 1 minute, 10 seconds, etc. in the above description is only described as an example, and is not limited thereto.
In addition, a program to be recorded with priority is determined in advance, and if both are in a good reception state in step S11 and both are in a bad reception state, the priority program is recorded.

[Example 2]
FIG. 1 is a block diagram showing a second embodiment of a mobile phone capable of receiving digital broadcasting. This mobile phone 30 has a structure in which a current position acquisition unit 31 and a broadcast reception area storage unit 32 are added to the mobile phone 10 of the first embodiment shown in FIG.
The current position acquisition unit 31 acquires the current position (latitude, longitude) of the mobile phone 30 using GPS (Global Positioning System) or the like.
The broadcast reception area storage unit 32 stores a receivable area of each broadcast station.

The operation of the mobile phone according to the first embodiment in which the overlapping recording reservation is made will be described with reference to the flowchart of FIG.
The operations in steps S1, 2, and 3 in the first embodiment and steps S21, 22, and 23 in the second embodiment are the same.
When there is an overlap in the recording reservation time (step S23; Yes), the control unit 20 acquires the current position of the mobile phone 30 from the current position acquisition unit 31 (step S24). The control unit 20 collates the acquired current position with the reception area information of each broadcast station stored in advance in the broadcast reception area storage unit 32 in the terminal (step S25), and the broadcast station with the higher reception level. Is selected (step S26).

  Here, if the reception area information is not stored in the mobile phone, the acquired current position information is transmitted via communication to a server that provides the reception area information. There is also a method for obtaining information on whether the reception state is good.

  The program recording process of the broadcasting station with the good reception state determined in step S26 is performed. Steps S26 to S31 perform the same processing as steps S11 to S16 of the first embodiment. The effect of the second embodiment is the same as that of the first embodiment.

[Modification]
If the program being recorded becomes unreceivable due to movement of the mobile phone during the overlapping reserved program broadcast time, the reception status of the other broadcast station that is not recorded can be confirmed, and if good, the recording process can be performed. it can. Although only a part of the program or stored content can be recorded, it is often useful for the user.

In the first embodiment, a broadcast station that can be received more stably is selected from the information indicating the reception state acquired from the tuner, and in the second embodiment, from the current position information and the reception area information. You may carry out by the method like this.
A database of a combination of past reception history and position information is stored in the mobile phone, and it is determined that reception is possible if there is a reception history at the same position in the past from the database.
Weighting may be performed at the time of selection according to the reception state of the recording start time of the duplicate program. For example, when reservations for programs A and B overlap, the reception level of the broadcast station for program A is not less than X, but the reception level of the broadcast station for program B is not less than Y.

  The present invention can be provided even when recording reservations are duplicated in the same broadcasting system. For example, even in 1Seg, depending on the area, a certain channel can be received well, but another channel may not be received. In such a case, even if the one-segment recording reservations overlap, the reservation is accepted as it is at the time of reservation, the reception state is confirmed at the recording start time, and the program to be actually recorded is selected.

  The program that operates in the broadcast receiving apparatus according to the present invention may be a program that controls a CPU (Central Processing Unit) or the like (a program that causes a computer to function) so as to realize the functions of the above-described embodiments related to the present invention. good. Information handled by these devices is temporarily stored in RAM (Random Access Memory) during the processing, and then stored in various ROMs such as Flash ROM (Read Only Memory) and HDD (Hard Disk Drive). Reading, correction, and writing are performed by the CPU as necessary.

  In addition, a program for realizing the function of each component may be recorded on a computer-readable recording medium, and the program recorded on the recording medium may be read into a computer system and executed to perform processing of each unit. Good. Here, the “computer system” includes an OS and hardware such as peripheral devices.

  The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. Furthermore, the “computer-readable recording medium” dynamically holds a program for a short time like a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line. In this case, a volatile memory in a computer system serving as a server or a client in that case, and a program that holds a program for a certain period of time are also included. The program may be a program for realizing a part of the functions described above, and may be a program capable of realizing the functions described above in combination with a program already recorded in a computer system. Further, part or all of the broadcast receiving apparatus in the above-described embodiment may be realized as an LSI that is typically an integrated circuit.
