Abstract: A media gateway (MG) that services a plurality of client devices, may be handled at least a portion of video conferencing (VC) processing during a VC call between at least one of said plurality of client devices and at least one other VC client. The portion of the VC processing handled by the media gateway may be offloaded from a centralized VC multipoint control unit (MCU). The MG may handle one or more VC MCU functions, which may comprise video conferencing call control and/or management and/or audio/video (AV) transcoding. The MG may perform localized quality of service (QoS) management, to select, and adaptively control and/or configure resources and/or local links used in the MG and/or in VC clients or neighboring MGs connected to the MG, during VC operations, such as in generating, handling, and/or communicating data or content exchanged during VC calls.

Abstract translation: 服务多个客户端设备的媒体网关（MG）可以在所述多个客户端设备和至少一个其他VC客户端中的至少一个之间的VC呼叫期间处理视频会议（VC）处理的至少一部分。 由媒体网关处理的VC处理的部分可以从集中式VC多点控制单元（MCU）卸载。 MG可以处理一个或多个VC MCU功能，其可以包括视频会议呼叫控制和/或管理和/或音频/视频（AV）代码转换。 在VC操作期间，MG可以执行本地化的服务质量（QoS）管理，以选择和/或配置在MG和/或连接到MG的VC客户端或相邻MG中使用的资源和/或本地链路。 ，例如在生成，处理和/或传送在VC呼叫期间交换的数据或内容。
