(Operation)
The operation of the program selection recording system in the first embodiment of the present invention will be described below with reference to FIGS.

  FIG. 10 is a flowchart relating to extraction of search keywords from the voice information purchase history according to the first embodiment of the present invention.

  A description will be given by taking the first audio information extraction priority list in which the audio information meta information is arranged in the order of purchase history as an example. Here, recording audio information such as a CD in the storage unit for the first time from the disk reading unit 201 is also regarded as purchase.

  Newly purchased voice information, when the voice information distribution service 102 or CD or the like is newly purchased, or when the time for updating the voice information extraction priority list defined by the user (elapse of a certain period) has come (s101; Yes) The first audio information extraction priority list is updated based on the audio information meta information of the information (s102). First audio information meta-information is extracted from the update result (s103). A first search keyword is further extracted from the first audio information meta information (s104). The extracted first search keyword is stored in the first memory 203, and the process ends (s105).

  It should be noted that the user can arbitrarily specify when the first audio information extraction priority list is updated and which information in the audio information meta information is selected and extracted.

  Here, in step s101, if the voice information is not newly purchased or the update period determined by the user is not reached (s101; No), the process returns to step s101 and the processing is continued.

  FIG. 11 is a flowchart relating to extraction of search keywords from a playlist according to the first embodiment of the present invention.

  A description will be given by taking as an example a second audio information extraction priority list in which audio information meta-information in a newly created playlist is arranged.

  When the user creates a new playlist or the update time of the second audio information extraction priority list determined by the user comes (s111; Yes), based on the audio information meta-information of the recently created playlist The second audio information extraction priority list is updated (s112). The second audio information meta information is extracted from the update result (s113). A second search keyword is further extracted from the extracted second audio information meta information (s114). The extracted second search keyword is compared with the first search keyword stored in step 105 to extract a new third search keyword (s115). The third search keyword is transmitted to the recording device 20 and the process is terminated (s116).

  Here, in step s111, if a new playlist is not created or if the update time set by the user is not reached (s111; No), the process returns to step s111 to continue the processing.

  FIG. 12 is a flowchart relating to selection of a program that matches the user's preference according to the first embodiment of the present invention.

  The recording apparatus 20 that has received the third search keyword after finishing the processes in FIGS. 10 and 11 (s121) collects the EPG information 104 flowing in the broadcast radio wave (s122). A program that matches the user's preference is selected from the EPG information 104 and the third search keyword (s123). The channel and broadcast time of the selected program are displayed on the display unit 307, and the process is terminated (s124).

  The network television receiver 30 selects and displays a program that matches the user's preference on the third display unit 407 by the same operation as the flowchart of FIG.

  FIG. 13 is a flowchart relating to recording reservation of a program that meets the user's preference according to the first embodiment of the present invention.

  The recording apparatus 20 that has received the third search keyword after finishing the processing in FIGS. 10 and 11 (s131) collects the EPG information 104 flowing in the broadcast radio wave (s132). A program that matches the user's preference is selected from the EPG information 104 and the third search keyword (s133). The selected program is reserved for recording and the process is terminated (s134).

  FIG. 14 is a flowchart relating to the portable terminal 40 according to the first embodiment of the present invention. Since the PC 10 has the same configuration, the same operation is possible.

  The portable terminal 40 ends the processes in FIGS. 10 and 11 and extracts the third search keyword (s141). The e-mail creation unit 503b creates an e-mail and sends the e-mail to the address of the recording device 20 (s142). The recording device 20 receives only the mail in which the search keyword is written from the mail box (s143). A fourth search keyword is extracted from the received e-mail (s144). If the fourth search keyword extracted below is used to automatically select a program that matches the user's preference, the flowchart of FIG. 12 is executed, and if the program is to be automatically reserved for recording, the flowchart of FIG. 13 is executed.

  FIG. 15 is a timing chart showing transmission / reception between the PC 10 and the recording apparatus 20 according to the first embodiment of the present invention.

  The recording device 20 checks whether a device is connected using UPnP (Universal Plug and Play) or the like (s151). The PC 10 receives it, sends back device information and service information, and the recording device 20 receives it (s152). The recording apparatus 20 determines whether or not the other party can request the search keyword, and requests the search keyword (s153). The PC 10 receives the request and transmits a search keyword (s154). The recording device 20 receives the search keyword (s155), and performs a recording reservation process based on the received search keyword.

(Effects of the first embodiment)
According to the first embodiment described above, a program that matches the user's preference can be automatically selected and matched to the preference with high accuracy.

[Second Embodiment]
FIG. 16 is a flowchart relating to a search keyword filter according to the second embodiment of the present invention. In the following description, parts having the same configuration and function as those of the first embodiment are denoted by common reference numerals.
(Operation)

  A description will be given by taking as an example a third audio information extraction priority list in which audio information meta-information is arranged in order of newest reproduction history of audio information.

  When the number of purchase histories and playlists is large, the user can add a reproduction history to search keyword extraction. The third audio information extraction priority list is updated based on the audio information meta-information of the audio information that has been recently played back or frequently played back (s161). The fourth audio information meta information is extracted from the update result (s162). A fourth search keyword is further extracted from the extracted fourth audio information meta information (s163). The fifth search keyword is newly extracted by comparing the extracted fourth search keyword with the third search keyword extracted in step 116 (s164). The fifth search keyword is transmitted to the recording device 20 and the process is terminated (s165).

(Effect of the second implementation)
According to the above-described embodiment, when the purchase history and the playlist increase, and when there is a deviation from the program that suits the user's preference, the playback history is newly added as a keyword extraction means for higher accuracy. The user can select a program that matches the user's preference.

  The program selection recording system of the present invention has been described based on the above embodiment, but the present invention is not limited to the above embodiment, and can be implemented in various modes without departing from the gist thereof. Is possible.
