Abstract: In one embodiment, an apparatus includes two modules. A first module receives a request from a first endpoint to subscribe to a voice activated multicast group and causes the first endpoint to receive a current speaker's video stream if the first endpoint is not the current speaker and to receive a last speaker's video stream if the first endpoint is the current speaker. A second module receives a request from a second endpoint to subscribe to a continuous presence multicast group and causes the second endpoint to receive a continuous presence, current speaker video stream if the second endpoint is not the current speaker and to receive a continuous presence, last speaker video stream if the second endpoint is the current speaker. The continuous presence, current speaker video stream includes a composition or two or more video streams, one of which includes at least a portion of the current speaker's video stream. The continuous presence, last speaker video stream includes a composition or two or more video streams, one of which includes at least a portion of a last speaker's video stream.

Abstract: Playback of multimedia data associated with a recorded conference session is simplified, particularly for a person who participated in the conference session from a mobile device. At a recording server that is in communication with a plurality of endpoints in a conference session, multimedia received from the plurality of endpoints participating in the conference session is recorded. The recording server obtains geographical location information for at least one mobile endpoint participating in the conference session as the at least one mobile endpoint moves. The recording server temporally correlates the geographical location information for the at least one endpoint with recorded multimedia data for the conference session. The recording server stores data tags for the geographical location information for the at least one mobile endpoint in association with the recorded multimedia data for subsequent use in indexing to map data to retrieve a portion of the recorded multimedia data for playback.
Abstract translation: 与记录的会议会话相关联的多媒体数据的回放被简化，特别是对于从移动设备参与会议会话的人来说。 在与会议会话中的多个端点通信的记录服务器中，记录从参与会议会话的多个端点接收到的多媒体。 当至少一个移动终端移动时，记录服务器获得参与会议会话的至少一个移动终端的地理位置信息。 记录服务器将至少一个端点的地理位置信息与会议会话的记录的多媒体数据暂时相关。 记录服务器存储与记录的多媒体数据相关联的用于至少一个移动端点的地理位置信息的数据标签，用于随后用于索引以映射数据以检索记录的多媒体数据的一部分用于回放。
