For example, if it is confirmed that the time is 5 hours ago, the network I / F 83 is controlled based on the stored recording reservation information, and the reservation as shown in FIG.
- the content information D is transmitted to the server 2.
- the reserved content information d1 of the broadcast content having the content ID “0100” is the broadcast start date and time of “2002/03/14
- the reserved content information D may include a plurality of pieces of reserved content information. Further, when the content ID is included in the reservation content information D, the reservation content information D transmitted from the broadcast receiving and recording apparatus 3 may be only the content ID.
- step S101 the CPU 31 of the server 2 receives the reserved content information D via the communication unit 39, and in step S102, the CPU 31 includes the reserved content information D in the reserved content information D. Matching processing of the broadcast contents and the broadcast contents of the content change information C registered in the change information database 12 is executed.
- the matching processing in step S102 is the same processing as the matching processing in step S2 in FIG. 4, and the description thereof will be repeated, but the description is omitted. If the content information does not have the content ID, the matching process shown in FIG. 6 is executed, and if the content information does not have the content ID, the matching process shown in FIG. 9 is executed.
- step S102 for example, based on the content ID "0100" of the reservation content information d1 in FIG. 14A, the content change information c2 in FIG. Reserved to be Whether the broadcast content of the content information D and the broadcast content of the content change information C are determined to be the same broadcast content, that is, content change information corresponding to the broadcast content of the reserved content information D is stored in the change information database 12. It can be seen whether or not it is in the registered content change information C.
- step S103 it is determined whether or not the content change information corresponding to the broadcast content of the reserved content information D is included in the content change information C, and the content change information corresponding to the broadcast content of the reserved content information D is determined. If it is determined that there is content change information, in step S 104, the CPU 31 transmits the corresponding content change information E from the change information database 12 to the communication unit 39, and To the broadcast receiving and recording device 3 via the.
- the content change information el as shown in FIG. 14B (similar to the content change information c1 in FIG. 8) is transmitted from the change information database 12 to the broadcast receiving and recording apparatus 3. Sent to.
- the content change information E transmitted from the server may transmit only the change code and the changed value of the change item.
- the CPU 80 of the broadcast receiving and recording apparatus 3 receives the content change information E corresponding to the reserved content via the network I / F 83 and sends it to the hard disk drive 85 via the hard disk drive controller 84. To supply. Thereafter, based on the content change information E corresponding to the reserved content, the recording reservation information recorded on the built-in hard disk may be changed, or the broadcast content reserved for recording is changed. The display may be displayed on the monitor 77 or an e-mail may be sent to warn the user.
- the reserved content information is transmitted to the server 2 five hours before the broadcast start time corresponding to the broadcast start date and time of the reserved content, but the transmission time is set by the user.
- the number of transmissions may be any number.
- the reservation content of the corresponding broadcast content Although only the recording information is transmitted, all the recording reservation information recorded on the internal hard disk may be transmitted. Alternatively, when the recording reservation information is recorded, it may be transmitted at regular intervals.
- the broadcast receiving device 3 transmits the reserved content information to the server 2 at an appropriate time and checks whether or not the broadcast content reserved for recording has been changed. It is provided efficiently when change information of reserved broadcast content is needed.
- the server 2 obtains the content information periodically and determines whether the change information of the content information includes the broadcast content corresponding to the reserved content information, the process of confirming the change of the content information can be performed at high speed. It is better to make it.
- the series of processes described above can be executed by hardware, but can also be executed by software.
- the programs that make up the software are installed in a computer that is embedded in a dedicated hard disk or by installing various programs to perform various functions. It is installed from a program storage medium to a general-purpose personal computer that can be executed, for example.
- a program storage medium for storing a program installed in the computer and made executable by the computer includes a magnetic disk 51 (including a flexible disk), an optical disk 52 (CD-band), and the like.
- Package media consisting of Corapact Disc-Read Only Memory (DVD) (including Digital Versatile Disc), magneto-optical disc 53 (including MD (Mini-Disc) (trademark)), or semiconductor memory 54 Or, it is composed of a ROM 32 in which the program is temporarily or permanently stored, and a storage unit 38.
- the step of describing a program recorded on a recording medium is not limited to processing performed in chronological order according to the described order, but is not necessarily limited to time. Even if they are not processed sequentially, they also include processes that are executed in parallel or individually.
- system refers to an entire device including a plurality of devices.
- broadcast content change information is provided as required by the user. Also, change information of broadcast contents is provided efficiently.
