- the search keyword can be associated with the reproduction information including the time information when the operation for inputting the search keyword is started, the search keyword is reproduced along the time axis. It is possible to appropriately associate the search keyword with the content information.
- the search keyword input information generation unit calculates the time when the search keyword was acquired, the time required to input the search keyword, and the time information when the operation for inputting the search keyword was started.
- the search keyword input terminal will be described.
- FIG. 35 illustrates a functional block diagram of the search keyword input terminal according to the present embodiment.
- the search keyword input terminal 3500 includes a content information reproduction unit 801, a search keyword input unit 802, and a search keyword input information generation unit 803.
- the content information playback unit 801 has playback position information acquisition means 1301, and the search keyword input information generation unit 803 has reverse calculation acquisition means 3501.
- the configuration of the search keyword input terminal according to the present embodiment is a configuration in which the reverse keyword acquisition means 3501 is provided in the search keyword input information generation unit 803 in the search keyword input terminal according to the thirteenth embodiment.
- "Back-calculation acquisition means" 3501 obtains and calculates the reproduction position information, which is time information, by obtaining and calculating the time when the operation for inputting the search keyword is completed and the time required for inputting the search keyword. It is means for obtaining reproduction information including.
- the search keyword input unit 802 generates the search keyword input information generation immediately after the operation for inputting the search keyword is completed, and the time required for inputting the search keyword. Assume that the output is to part 803.
- the time when the search keyword input information generation unit 803 acquires the search keyword may be regarded as the time when the operation for inputting the search keyword is completed. Accordingly, the reverse calculation acquisition means 3501 subtracts the time required for inputting the search keyword from the time when the search keyword input information generating unit 803 acquires the search keyword, thereby performing an operation for inputting the search keyword. You can get the time information when is started.
- search keyword input information generation unit 803 For example, as illustrated in FIG. 35, information related to a search keyword "Sweet Cherry Blossom Town" and a time of 30 seconds as input time for the search keyword is searched. It is assumed that the keyword input information generation unit 803 has acquired. In addition, it is assumed that the playback position information of 17 minutes 45 seconds from the start of content information playback is acquired at the time of acquisition. Then, the reverse calculation acquisition means 3501 subtracts 30 seconds from 17 minutes 45 seconds to acquire time information of 17 minutes 15 seconds, and the search keyword input information generation unit 803 reads “confectionery” from 17 minutes 15 seconds. It is determined that an operation for inputting a search keyword “Sakuramachi” has started, and search keyword input information is generated.
- FIG. 36 illustrates a flowchart illustrating a process in which the search keyword input unit 802 obtains the time required to input the search keyword in the present embodiment.
- step S3601 the process waits until character input of the search keyword is started.
- step S3602 the process proceeds to step S3602, and a timer is started.
- step S3603 the process waits until the input of the search keyword is completed.
- step S364 the time required for inputting the search keyword is calculated based on the timer value.
- the search keyword input unit outputs the time calculated in step S3605 to the search keyword input information generation unit 803 in association with the input search keyword.
- any method may be used.
- the completion of Kana-Kanji conversion may be the completion of the input of the search keyword.
- the input of a search keyword may be completed when a specific button or key is pressed. For example, when a submit button or return key is pressed. Alternatively, it may be a key that represents a punctuation mark such as a period. Further, it may be detected that the operation is not performed for a predetermined time. Alternatively, the completion of the input of the search keyword may be detected when the input of the next search keyword is started.
- the search keyword input information is generated from the search keyword input unit 802. Since it is only necessary to send information to the part 803 once for each input of the search keyword, the structure of the search keyword input part 802 and the search keyword input information generation part 803 is simplified.
- the search engine can be used to search, and it is particularly useful in the industry because it has the effect of eliminating the need to enter characters.
