To control.

Next, a search word accumulation method, a content output / recording control method, and a display control method, which are features of the present invention, will be described in detail.
(A) Search Word Accumulation Method A search word accumulation method according to Embodiment 1 of the present invention will be described with reference to FIG. FIG. 5 is a flowchart showing a flow from reading a character string from text information stored in the text information storage unit 202, extracting a word, and storing a search word in the search word storage unit 206. In the following description, it is assumed that the word “genre” is designated as an index for limiting the accumulation of search words. The character string stored in the text information storage unit 202 is read (step S501). The word extraction unit 205 performs morphological analysis on the read character string, and temporarily stores all words in the word storage buffer (step S502). One word is extracted from the word storage buffer (step S503). If the extracted word has appeared in the past (no in step S504), the process jumps to step S510. If the extracted word has not appeared in the past (yes in step S504), it is searched whether the word exists in the dictionary data section 204 (step S505). If the word does not exist in the dictionary data portion 204 (No in step S506), the process jumps to step S510. When the word exists in the dictionary data part 204 (yes of step S506), the genre of the word is read from the dictionary data part 204 (step S507). If the read genre does not belong to the genre set by the user (no in step S508), the process jumps to step S510. If the read genre belongs to the genre set by the user (yes in step S508), the word is stored in the search word storage unit 206 (step S509). The operations after step S503 are repeated until the word storage buffer becomes empty (step S510).
(B) Content Output / Recording Control Method A content output / recording control method according to Embodiment 1 of the present invention will be described with reference to FIG. FIG. 6 is a flowchart showing the flow of processing in the content output / recording control unit 214. In the following description, it is assumed that the user is viewing a teletext broadcast that is being broadcast. Further, the content output unit 212 has a chasing playback function (a function for playing back a recorded scene while viewing a program being recorded). In the following description, the content output unit 212 and the content recording unit 213 according to the present embodiment are controlled, but the same control can be performed for an external content reproduction device and content recording device. First, it is confirmed whether or not the linkage mode with the content output unit 212 and the content recording unit 213 is designated (step S601). If the interlock mode is not designated (no in step S601), nothing is done. If the interlocking mode is designated (step S601: yes), it waits for a search word to be selected (step S602). When the search word is selected (yes in step S602), the appearance time t0 of the selected word is acquired from the search word accumulation unit 206 and recorded in the time buffer. At this time, if the content output unit 212 is performing chasing playback (yes in step S604), a playback stop command is output to the content output unit 212 (step S605). If the content output unit 212 is not chasing playback (no in step S604) and the content recording unit 213 is not recording (no in step S606), a recording command is output (step S607), and the current time t1 is recorded in the time buffer. (Step S608). If the content output unit 212 is not chasing playback (no in step S604) and the content recording unit 213 is recording (yes in step S606), the recording start time t2 is recorded in the time buffer (step S609). Thereafter, the user finishes browsing the search word result and waits for the browse end key 108 to be pressed (step S610). When the browsing end key 108 is pressed (yes in step S610), the content output unit 212 outputs a rewind and chasing playback command to the time stored in the time buffer (step S611). That is, when the content output unit 212 selects a search word during chasing playback, after the search result is browsed, playback starts from the scene where the search word appears, and the content output unit 212 is not chasing playback. When the search word is selected when the content recording unit 213 is not recording, after the search result is browsed, the search is started from the scene at the time when the search word is selected.
(C) Display control method The display control method in Embodiment 1 of this invention is demonstrated using FIG. FIG. 7 is a flowchart showing the flow of processing in the display control unit 210. The following is a case where the stored search words are displayed in a list in order of appearance time in synchronization with the content. First, if no search word has been selected (no in step S701), if the content output unit 212 is currently chasing playback (yes in step S702), the playback time t3 is stored in the time buffer ( If the chasing reproduction is not being performed (step S703), the current time is stored in the time buffer (step S704). Then, the search word that appears at the time closest to the time stored in the time buffer among the search words stored in the search word storage unit 208 is displayed with the head (step S705). When a search word is selected (step S701: yes), the contents of the search result storage unit 208 are displayed (step S706). When the browsing end key is pressed (yes in step S707), the process jumps to step S702. The list display is not limited to the order of appearance time described above, and can be in the order of 50 notes or in alphabetical order.

  As described above, according to the electronic dictionary device of the present invention, since it is not necessary to browse the search result while viewing the flowing content, the search can be performed without missing or listening to the content. You can browse the results carefully, and even if you browse the search results while viewing the flowing content, you can re-view the scenes that you missed or missed in the meantime.

  It is also possible to easily search for a word that appears while searching for a certain word.

  The above-described embodiment is realized by the CPU interpreting and executing predetermined program data stored in a recording device (ROM, RAM, hard disk, etc.) that can execute the processing procedure described above. In this case, the program data may be introduced into the recording apparatus via the recording medium, or may be directly executed from the recording medium. Here, the recording medium is, for example, a semiconductor memory such as a ROM, a RAM, or a flash memory, a magnetic disk memory such as a flexible disk or a hard disk, an optical disk such as a CD-ROM, DVD, or BD, or a memory card. The recording medium is a concept including a communication medium such as a telephone line or a conveyance path.

  In the above-described embodiment, each functional block is typically realized as an IC or LSI that is an integrated circuit. These may be made into one chip for each individual, or may be made into one chip so as to include a part or all of them.

  Further, the method of circuit integration is not limited to LSI's, and implementation using dedicated circuitry or general purpose processors is also possible. An FPGA (Field Programmable Gate Array) that can be programmed after manufacturing the LSI or a reconfigurable processor that can reconfigure the connection and setting of circuit cells inside the LSI may be used.

  The electronic dictionary device of the present invention does not have to browse the search result while viewing the flowing content, so that the search result can be browsed carefully without missing or listening to the content, Even if you browse the search results while watching the flowing content, you can re-view the scenes that you missed or missed during that time, so the electronic dictionary device Etc. are useful.
