Abstract:
Video coding techniques are disclosed for resource-limited destination display devices. Input video data may be coded by converting a first representation of the input video to a resolution of a destination display and base layer coding the converted representation. Additionally, a region of interest may be predicted from within the input video. The predicted ROI may be converted to a resolution of the destination display, and the converted ROI may be enhancement layer coded. The base layer coded data and the enhancement layer data may be transmitted to the destination display where the coded base layer data is decoded and displayed until a zoom event occurs. When a zoom event occurs, both the coded base layer data and the coded enhancement layer data may be decoded and displayed. Thus, the switchover from a first field of view to an ROI view may be performed quickly.
