Abstract: Method, device and computer program product for stabilizing a video signal. A plurality of frames of the video signal are captured using a camera. A motion sensor associated with the camera is used to generate a plurality of samples representing motion of the camera. The samples are used to determine a displacement of the camera between a first time and a second time, wherein the first time corresponds to an exposure time midpoint of a first frame of the video signal and the second time corresponds to an exposure time midpoint of a second frame of the video signal. The determined displacement is used to compensate for motion in the video signal between the first and second frames caused by the motion of the camera, to thereby stabilize the video signal.

Abstract: A method of performing a rate-distortion optimization process comprising, for each of a plurality of target image portions to be encoded in each of a plurality of frames, selecting a preferred one of a set of encoding modes by optimizing a function comprising an estimate of distortion for the target image portion and a measure of bit rate required to encode the target image portion, wherein the estimate of distortion is based on source coding distortion and an estimate of a distortion that would be experienced due to possible loss over the channel; encoding the target image portion into the encoded video stream using the selected encoding mode; and transmitting the encoded video stream over the channel. The rate-distortion optimization process for a current one of the frames is performed in dependence on feedback received from the receiving terminal based on an earlier one of the frames.

Abstract: Method, device and computer program product for stabilizing a received video signal. A plurality of frames of the video signal is captured using a camera. The video signal is transmitted as an encoded bit stream. Displacement of the camera between successive frames is determined from a motion indication in the bit stream. The determined displacement is used to compensate for motion in the video signal between successive frames caused by the motion of the camera, to thereby stabilize the video signal.
