Abstract

Presented herein is a method to adaptively archive recordings and meetings based on user interest analytics. The method provides flexibility for different late-coming viewers to choose a preferred viewing trajectory of a recorded event. It can also provide storage savings by automatically archiving seldom accessed segments of each recording at a lower quality and resolution.

ABSTRACT

Presented herein is a method to adaptively archive recordings and meetings based

on user interest analytics. The method provides flexibility for different late-coming viewers

to choose a preferred viewing trajectory of a recorded event. It can also provide storage

savings by automatically archiving seldom accessed segments of each recording at a lower

quality and resolution.

DETAILED DESCRIPTION

Many existing enterprise conferencing systems support the capability to record an

entire meeting or event for others to view later. This service is analogous to "time-shifted

viewing" in the context of television. Such recordings usually need to be archived in the

system over a long period of time (e.g., several years), and typically contain multiple

sources of input (e.g., video feeds from individual participants’ webcams, shared slides,

audio, multiple camera feeds capturing a big conference room or stage, etc.). In existing

systems, the recordings only preserve a "canonical" view containing a subset of these

content sources. For instance, a recording of a meeting may contain the merged audio track,

shared slides, and only the video thumbnail of the person who is speaking. However,

different viewers may be interested in different parts of the meeting at different instants of

time. It is also difficult to predict in advance which content source may draw more interest

from viewers.

For example, at time t in the recording of a technical demo, user A may be more

interested in zooming in on the camera view of the demo itself, user B may be more

interested in inspecting the accompanying slide illustrating a setup of the demo, and user

C may be more concerned with observing onsite audience responses to the demo. It is

challenging to pre-package a canonical view of the meeting recording that accommodates

and presents all three content feeds given with sufficient resolution. It is also difficult to

predict in advance which view to focus on.

As such, described herein is a method for efficiently archiving recordings of

meetings and events based on historical user viewing interest. The method involves two

stages: (1) the post-recording user interest gathering stage, and (2) the user interest driven

archiving stage.

In the post-recording user interest gathering stage, the system generally focuses on

data gathering. The initial version of the recording contains high-resolution representations

of all content sources. Instead of presenting the meeting recording in a prescribed canonical

view, this system permits time-shifted viewers to dynamically switch between different

content sources via a flexible graphical user interface (GUI), or to freely observe pre-

composed mash-up views (e.g., speaker thumbnail + audio + slides). T...
