METHOD AND APPARATUS FOR IDENTIFYING KEY INFORMATION IN A MULTI-PARTY MULTIMEDIA COMMUNICATION
An apparatus for identifying key information in a multi-party multimedia communication includes a processor, and a memory storing instructions that, when executed by the processor, configure the apparatus to perform a method. The method includes receiving multi-modal data including video data and audio data for each of multiple participants, and presentation data presented on one or more multimedia devices. Vision information and at least one of tonal information or text information is used to determine a representative participation score (RPS) for one or more participants. Content from presentation data presented during or proximate to pronounced RPS movement is identified and sent for display.

sending the first content, the second content, and the determined change for display.
5 . The method of claim 2 , further comprising:
identifying a hyper-relevant text keyphrase in the identified content; and
sending the identified hyper-relevant text keyphrase for display.
6 . The method of claim 1 , wherein the identifying content comprises optical character recognition (OCR).
7 . The method of claim 1 , wherein the determining the change comprises comparing consecutive frames.
8 . A computing apparatus comprising:
a processor; and
a memory storing instructions that, when executed by the processor, configure the apparatus to:
receive, at an analytics server, from a plurality of multimedia devices in a multimedia communication between a plurality of participants, multi-modal data comprising video data and audio data for at least one of the plurality of participants, and presentation data comprising data presented on at least one of the plurality of multimedia devices, wherein the plurality of multimedia devices are remote to the analytics server;
extract, for each of the plurality of participants, vision information from the video data, at least one of tonal information or text information from the audio data;
determine a representative participation score (RPS) based on the vision information and the at least one of the tonal information or the text information, for each of the plurality of participants, for a plurality of consecutive time intervals;
determine a pronounced RPS movement
for at least one of the plurality of participants during a first plurality of time intervals,
for at least two of the plurality of participants during a second plurality of time intervals, or
for at least a predefined duration for at least one of the plurality of participants during a third plurality of time intervals;
identify, from the presentation data, content relevant to the pronounced RPS movement, the content comprising at least one of a text element, an audio element, a graphic element, or a frame; and
send the identified content for display.
9 . The computing apparatus of claim 8 , wherein the identifying the content relevant to the pronounced RPS movement comprises identifying content presented
during the pronounced RPS movement, and
at least one of
a predefined duration or a predefined number of speaker turns before the pronounced RPS movement, or
at least one of a predefined duration or a predefined number of speaker turns after the pronounced RPS movement.
10 . The computing apparatus of claim 9 , wherein the at least one of predefined duration is 5 s, and the at least one of predefined turns is 2.
11 . The computing apparatus of claim 9 , wherein the instructions further configure the apparatus to:
determine, from the identified content, a change from a first content to a second content, the second content presented at a time after the first content; and
send the first content, the second content, and the determined change for display.
12 . The computing apparatus of claim 9 , wherein the instructions further configure the apparatus to:
identify a hyper-relevant text keyphrase in the identified content; and
send the identified hyper-relevant text keyphrase for display.
13 . The computing apparatus of claim 8 , wherein the identifying content comprises optical character recognition (OCR).
14 . The computing apparatus of claim 8 , wherein the determining the change comprises comparing consecutive frames.
15 . A non-transitory computer-readable storage medium, the computer-readable storage medium including instructions that when executed by a computer, cause the computer to:
receive, at an analytics server, from a plurality of multimedia devices in a multimedia communication between a plurality of participants, multi-modal data comprising video data and audio data for at least one of the plurality of participants, and presentation data comprising data presented on at least one of the plurality of multimedia devices, wherein the plurality of multimedia devices are remote to the analytics server;
extract, for each of the plurality of participants, vision information from the video data, at least one of tonal information or text information from the audio data;
determine a representative participation score (RPS) based on the vision information and the at least one of the tonal information or the text information, for each of the plurality of participants, for a plurality of consecutive time intervals;
determine a pronounced RPS movement
for at least one of the plurality of participants during a first plurality of time intervals,
for at least two of the plurality of participants during a second plurality of time intervals, or
for at least a predefined duration for at least one of the plurality of participants during a third plurality of time intervals;
