<P>PROBLEM TO BE SOLVED: To provide a method and an apparatus for encoding video, such as surveillance video. <P>SOLUTION: A video frame is encoded by: evaluating a level of activity in video frame relative to one or more neighboring frames; encoding the video frame using an inter-coding technique if the evaluation satisfies one or more predefined inter-coding criteria, wherein the inter-coding technique is applied to the video frame without a Group of Pictures structure having a maximum number of consecutive inter-coded frames; and encoding the video frame using an intra-coding technique if the evaluation satisfies one or more predefined intra-coding criteria. The evaluating step may comprise, for example, determining whether differences between the video frame and the one or more neighboring frames exceed a predefined threshold. <P>COPYRIGHT: (C)2011,JPO&INPIT |
