摘要:
A method and apparatus for recording and indexing audio information exchanged during an audio conference call, or video, audio and data information exchanged during a multimedia conference. For a multimedia conference, the method and apparatus utilize the voice activated switching functionality of a multipoint control unit (MCU) to provide a video signal, which is input to the MCU from a workstation from which an audio signal is detected, to each of the other workstations participating in the conference. A workstation and/or participant-identifying signal generated by the multipoint control unit is stored, together or in correspondence with the audio signal and video information, for subsequent ready retrieval of the stored multimedia information. For an audio conference, a computer is connected to an audio bridge for recording the audio information along with an identification signal for correlating each conference participant with that participant's statements.
摘要:
A method and processing system for the indexing of data for one or more users involving the steps of receiving primary data, delineating episode data from the primary data, generating media representations to correspond with the episode data, generating a table of contents from the episode data and media representations in real time, and storing and/or presenting the table of contents on a graphical user interface. Primary data may constitute audio data, video data, text data, combinations of these as well as any medium-generated data which may be in or converted to digital form. Episode data is generated on the basis of significant video images determined by scene changes and other information. In addition, episode data may be based on a significant audio change, delineated from the primary data, e.g. based on speaker changes and other information. Media representations are iconic images, symbolic representations or graphical images which refer to episode data to ultimately aid the user in making decisions from reviewing the real time table of contents.
