  Step 109) The inter-viewer communication unit 1 displays the video and the comment corresponding to the scene section from the data storage unit 2 on the user terminal.

  Step 110) When a scene section exists in the data storage unit in Step 102, a list of representative videos of the scene section is displayed.

  Step 111) When a comment is input from the viewer, the comment is stored in the data storage unit 2 in association with the scene section.

  Step 112) The comment acquisition unit 3 acquires and analyzes the comment information from the data storage unit 2, and passes the analysis result to the scene section detection unit 4.

  Step 113) The scene section detection unit 4 detects a scene section based on the acquired analysis result. Detailed processing will be described in the second to fifth embodiments.

  Step 114) The scene section information update unit 5 stores the detected scene section in the data storage unit 2. Control goes to step 109.

[First Embodiment]
In this embodiment, the scene section information is not set in the data storage unit 2, and a process of newly detecting a scene section and setting it in the data storage unit 2 will be described.

  FIG. 7 is a flowchart of processing of the scene section detection unit based on comment analysis according to the first embodiment of this invention.

  The operation shown in the figure is that a scene section is undefined, that is, the scene section information managed by the data storage unit 2 is newly analyzed by comment analysis from the state where the beginning and end of the video are one scene. This defines a simple scene section.

  Step 201) The scene section detection unit 4 reads the time when the comment is given from the comment information management table of the data storage unit 2, and classifies the comment. At this time, with respect to the comments excluding those whose comment type is “Reply”, a process in which a given time is shorter than a preset value is set as the same group. At this time, processing may be added so that the time interval between comments decreases as the number of replies and the total number of comment characters increases. In addition, when the number of comments in each classified group is less than or equal to a preset value, by deleting the group, when the number of comments for the entire video is small, it is divided into many short sections. Can be prevented.

  The scene section detection unit 4 manages N comment groups in the memory with numbers n = 1, 2,...

  Step 202) With n = 1, the scene sections corresponding to the first group are sequentially detected.

  Step 203) The time ts (n) given first is detected among the comments belonging to the group number n.

  Step 204) The time te (n) given last is detected among the comments belonging to the group number n.

  Step 205) As a margin when defining the scene section, a margin time a for the start of the section and a margin time b for the end of the section are set in advance, and time ts (n) -a and time te (n) + b Is detected as the scene section time.

  Step 206) It is determined whether all comment groups have been processed. If so, the process proceeds to step 205. If not, the process of step 207 is executed.

  Step 207) Processing for the next comment group is performed.

  Step 208) When the scene section time setting processing is performed for all comment groups, the following sections are detected as scene sections.

The section from the beginning of the video time to the time ts (1) -a;
From time te (n) −a to time te (n) + b (n = 1, 2,..., N−1)
From time te (n) + b to time ts (n + 1) -a (n = 1, 2,..., N−1)
From time ts (N) -a to time te (N) + b
FIG. 8 shows how the scene section is defined by the above processing from the time te (N) + b to the end of the video time. In the figure, the comment groups are classified into three, and finally seven scene sections are defined.

  When the scene is defined, the scene section is transferred to the scene section update unit 5, and the scene section update unit 5 updates the scene section information in the data storage unit 2. The scene section update unit 5 assigns a scene ID to each scene obtained above, and identifies the start time (ts) and end time (te) for each scene, and comments within the start time and end time. The number is stored in the scene section information table of the data storage unit 2.

[Second Embodiment]
The configuration of the communication device in the present embodiment is the same as the configuration shown in FIG.

  In the following, a procedure for defining a new scene section by comment analysis when a scene section has already been defined (FIG. 6, Step 102, Yes) will be described.

  FIG. 9 is a flowchart of processing of the scene section detection unit by comment analysis according to the second embodiment of the present invention. In the following processing, operations similar to those in the flowchart shown in FIG. 7 are denoted by the same step numbers and description thereof is omitted.

  Step 301) s = 1 is set for s (s = 1, 2,..., S) which is an identification number of an existing scene section.

  Step 302) The comment information assigned to the scene section with the identification number s is read from the data storage unit 2.

  Step 201) The comment classification process of step 201 in FIG. 7 is performed on the comment information acquired in step 302.

  Step 303) It is determined whether or not the number of classified comment groups is larger than 1. If the number is larger, the process proceeds to Step 202. If not, the process proceeds to Step 305.

  Thereafter, the processing of steps 202, 203, 204, 206, and 207 in FIG. 7 is executed.

Step 304) The scene section s is divided into N sections of the number of comment groups. The separator between the nth and n + 1th scene sections is
te (n) + (ts (n + 1) -te (n)) / 2
And

  Step 305) It is determined whether all existing scene sections have been processed. If so, the entire process is terminated. If not, the process of step 304 is executed.

  Step 306) Perform processing for the next existing scene section.

  FIG. 10 shows how an existing scene section is divided by the processing described above. Since the existing “scene section 2” in the figure has been classified into two comment groups, it is divided as shown in the scene section defined after the end of processing. As described above, when there is a long scene section, it is appropriately divided.

[Third Embodiment]
The configuration of the communication device in the present embodiment is the same as the configuration shown in FIG.

  In the following, a procedure for defining a new scene section by comment analysis when a scene section has already been set (FIG. 6, step 102, Yes) will be described using FIG.

  In the present embodiment, when a section that is the same topic for the viewer is divided into a plurality of sections in the existing scene sections, the scene section detection unit 4 uses the similarities for the sections. Will be described.

  FIG. 11 is a flowchart of processing of the scene section detection unit by comment analysis according to the third embodiment of the present invention.

  Step 401) s = 1 is set for s (s = 1, 2,..., S) which is an identification number of an existing scene section.

  Step 402) The comment information given to the scene sections of the identification numbers s and s + 1 is read from the data storage unit 2.

  Step 403) A morphological analysis is performed on the comment portion of the comment information acquired in Step 402.

  Step 404) From the result of the morphological analysis, the frequency distribution of the noun for the scene section with the identification number s and the frequency distribution of the noun for the scene section with the identification number s + 1 are obtained. It is also effective to count similar nouns together by preparing dictionary data of nouns with similar meaning when obtaining the frequency distribution.

  Step 405) For the nouns with the above frequency set in advance, the number ns (s, s + 1) of nouns common in the scene section of the identification number s and the identification number s + 1 is calculated.

  Step 406) It is determined whether the number of common nouns ns (s, s + 1) is larger than a preset value NS. If it is larger, the process proceeds to step 407. If it is not larger, the process of step 408 is executed.

  Step 407) The scene sections of the identification number s and the identification number s + 1 are integrated into one section.

  Step 408) It is determined whether all existing scene sections existing in the data storage unit 2 have been processed. If so, the entire process is terminated. If not, the process of step 409 is executed.

  Step 409) Perform processing for the next existing scene section.

  An example in which existing scene sections are integrated by the above processing is shown in FIG. An example is shown in which it is determined that the existing “scene section 2” and “scene section 3” have a high degree of similarity, and these are integrated. As described above, when a section that is the same topic for the viewer is divided into a plurality of sections in the existing scene section, these sections are integrated.

[Fourth Embodiment]
The configuration of the communication device in the present embodiment is the same as the configuration shown in FIG.

  In the present embodiment, a scene segment division process and a scene segment integration process performed by the scene segment detection processing unit 4 based on comment analysis will be described.
