More Information
Summary:A video call method in a portable terminal and an apparatus thereof are provided to prevent the processing of video frames from being delayed and stabilize the CPU occupancy of a video decoder by selectively displaying video frames, which are received and accumulated in a video call. If a video call starts(401), a portable terminal displays received video frames and measures video call system resources(403). The portable terminal checks whether video frames, received from the other side's terminal, are accumulatively stored in a buffer(405). If the received video frames are accumulatively stored in the buffer, the portable terminal decodes all the accumulatively stored video frames, measures the number of the video frames, and determines the number of video frames to be skipped using the measured video call system resources(407). The portable terminal selects video frames to be skipped according to the determined number among the decoded video frames, discards them, and displays the other frames.
