ABSTRACT

    An approach is presented herein to solve the large conference roster reporting problem by introducing an active roster that includes predetermined fixed users and dynamically selected active speakers. An algorithm is provided to select the active speakers.

DETAILED DESCRIPTION

    Supporting a roster (list of participants) is a common feature in multimedia conferences. When the conference size is small, a full roster can be shared among all the participants in the conference. However, when the number of participants/invitees for the conference gets very large, sending the full roster can be problematic. The problem is largely due to the high cost of computing resources to send the roster to all the participants and due to the delay for clients to receive the complete list, particularly, when many participants join the conference at approximately the same time. On the other hand, it is a useful feature to provide the roster to meeting participants so that they know people in the conference, can mute/unmute participants, subscribe/unsubscribe to a stream, etc. This roster may not be complete but should contain those participants the user wants to see.

    Presented herein is a solution that introduces a special roster that contains well- selected users as well as an on-demand roster. More specifically, the common scheme of a request-based roster is provided to allow users to obtain the entire roster, if he/she wants it. In addition, a special well-selected roster is provided that reflects the current conference active status changes and tendency. This roster is called an active roster

while the request-based roster is simply called the roster. FIG. 1 below shows a possible user interface display arrangement for these two lists.

    The special roster could roughly be classified into two categories: fixed users and active speakers.

Fixed Users:

    The fixed users are those participants whose roles have special meaning for the conference and are unlikely to change over the conference session. The fixed users are application dependent. In general, they may include the conference hosts, organizers, presenters (one or more at the same time or at different times), panelists and special users who may be assigned by the host in run time. This list should be small.

Active Speakers:

    The active speakers include two types of speakers. The first type, called frequent speakers, are those speakers who actively speak, though their speech each time could be relatively short and the total talk time may not be long. The second type, called long talking speakers, are those who tal...
