Frame dropping for streams of images frames

摘要

One or more streams of image frames are processed wherin a packetizer uses a filtering-out pattern to drop frames of image data and the receiver replaces dropped frames with copies of received frames. Patterns are applied regardless of the content or characteristics of the particular image frames being filtered out, or their similarity or dissimilarity to adjacent or neighboring image frames. Examples are removing every second or every nth frame, or passing or transmitting a plurality of image frames for every frame that is filtered out, for example removing n frames out of every m>n frames to be sent. Computer graphics may correspond to content that does not change frequently and removal of such image frames has low impact upon the perceived image quality. Dropping of frames is well-suited for use with computer graphic images and may be enabled when computer graphics are being transmitted and disabled for video data.
