Non-transitory computer readable medium, information processing apparatus, and information processing system

Abstract

A non-transitory computer readable medium stores a program causing a computer to transmit and receive multimedia data including at least one of sound data and video data between plural terminals connected to each other through a network to communicate with each other. The program causes the computer to function as a detection section and an association section. The detection section detects an event occurring when the plural terminals communicate with each other. The association section associates event information relating to the event with the multimedia data based on time information included in the multimedia data and a time when the detection section detects the event.

What is claimed is: 
     
         1 . A non-transitory computer readable medium storing a program causing a computer to transmit and receive multimedia data including at least one of sound data and video data between a plurality of terminals connected to each other through a network to communicate with each other, the program causing the computer to function as:
 a detection section that detects an event occurring when the plurality of terminals communicate with each other; and   an association section that associates event information relating to the event with the multimedia data based on time information included in the multimedia data and a time when the detection section detects the event.   
     
     
         2 . The non-transitory computer readable medium according to  claim 1 , the program causing the computer to further function as:
 a receiving section that receives operation information indicating details of an operation that a user performs on one of the terminals; and   a determination section that refers to a storage section that stores the operation information and an event information type indicating a type of the event information corresponding to the operation information in association with each other, to determine the event information type corresponding to the operation information received by the receiving section,   wherein the association section associates the event information corresponding to the event information type with the multimedia data.   
     
     
         3 . The non-transitory computer readable medium according to  claim 2 , wherein
 the storage section stores the operation information, user information for identifying a user having performed the operation and the event information type corresponding to the operation information in association with each other, and   the determination section determines the event information type corresponding to the operation information received by the receiving section and the user information.   
     
     
         4 . The non-transitory computer readable medium storing a program according to  claim 1 ,
 wherein when the detection section detects as the event a user's operation to switch between pages of a material used in a conference, the association section associates the event information including
 time information indicating a time when the user switches between the pages, 
 a page number before the user switches between the pages, and 
 user information of the user who switches between the pages, 
   
       with the multimedia data. 
     
     
         5  . The non-transitory computer readable medium according to  claim 1 ,
 wherein when the detection section detects a user's operation to select a submitted message as the event, the association section associates the event information including
 time information indicating a time when the user selected the message, 
 details of the selected message, and 
 user information of the user who selects the message 
 
 
       with the multimedia data. 
     
     
         6  . The non-transitory computer readable medium according to  claim 1 ,
 wherein when the detection section detects an operation to change a user who makes a presentation in a conference as the event, the association section associates the event information including
 time information indicating a time when the user who makes the presentation is changed, and 
 user information of the user who makes the presentation before the change 
 
 
       with the multimedia data. 
     
     
         7 . The non-transitory computer readable medium according to  claim 1 , the program causing the computer to further function as:
 a receiving section that receives from a user a request for reproduction of the multimedia data corresponding to the event; and   a reproduction section that reproduces the multimedia data,   wherein the reproduction section reproduces a portion, corresponding to the event selected by the user, of the multimedia data.   
         8 . An information processing apparatus that transmits and receives multimedia data including at least one of sound data and video data between a plurality of terminals connected to each other through a network to communicate with each other, the information processing apparatus comprising:
 a detection section that detects an event occurring when the plurality of terminals communicate with each other; and   an association section that associates event information relating to the event with the multimedia data based on time information included in the multimedia data and a time when the detection section detects the event.   
     
     
         9 . An information processing system that transmits and receives multimedia data including at least one of sound data and video data between a plurality of terminals connected to each other through a network to communicate with each other, the information processing system comprising:
 a detection section that detects an event occurring when the plurality of terminals communicate with each other; and   an association section that associates event information relating to the event with the multimedia data based on time information included in the multimedia data and a time when the detection section detects the event.   
     
     
         10 . The non-transitory computer readable medium according to  claim 1 , wherein the detection section detects the event occurring when the computer and the terminals are communicating the multimedia data with each other. 
     
     
         11 . The non-transitory computer readable medium according to  claim 1 , wherein the events detected by the detection section is one selected from the group consisting of:
 a presenter's operation to switch between pages of a material used in a conference, the presenter making a presentation in a conference,   a participant's operation to switch between pages of the material, the participant being different from the presenter,   an operation to change the presenter to another person,   an operation to enter the conference,   an operation to exit the conference,   an operation to select a comment submitted during the conference,   an operation to input a handwritten character, and   an operation to totalize a questionnaire.   
     
     
         12 . The non-transitory computer readable medium according to  claim 1 , wherein the event information includes
 event identification information,   sound time information indicating a sound starting time and a sound termination time, and   information indicating details of the event.
