1.发明申请Method and Apparatus for Motion Based Participant Switching in Multipoint Video Conferences 审中-公开多点视频会议中基于运动的参与者切换的方法和装置公开(公告)号：US20150326825A1
公开(公告)日：2015-11-12
申请号：US14801145
申请日：2015-07-16
Applicant: Cisco Technology, Inc.
Inventor： Conrad Bebbington , Paul Bright-Thomas
IPC: H04N7/15 , H04N19/139
CPC classification number: H04N7/152 , H04N19/139
Abstract: In one embodiment, an apparatus comprises a memory that stores executable instructions and a processor that executes the instructions in order to determine, for plural received compressed video inputs, at least one motion vector included in each of the plural compressed video inputs; calculate, based on the determined motion vectors, a motion value corresponding to each of the plural compressed video inputs, the motion values representing a level of motion over several frames for each of the plural compressed video inputs; and select, based on the calculated motion values, at least one of the plural compressed video inputs to be displayed.
Abstract translation: 在一个实施例中，一种装置包括存储可执行指令的存储器和执行指令的处理器，以便为多个接收的压缩视频输入确定包含在多个压缩视频输入中的每一个中的至少一个运动矢量; 基于所确定的运动矢量计算与所述多个压缩视频输入中的每一个相对应的运动值，所述运动值表示所述多个压缩视频输入中的每一个的几帧上的运动水平; 并且基于所计算的运动值，选择要显示的多个压缩视频输入中的至少一个。
