Abstract: A TV graphical user interface provided on a TV screen includes a graphical channel changer for enabling a user to select a required TV channel among about 1000 channels carried by a satellite TV system. The graphical channel changer contains a vertical channel bar composed of channel boxes that display numbers and logos of selected TV channels. To switch the TV set to a required TV channel, the user directs the pointing device at the graphical channel box that indicates the required channel. Up and down scroll bars, that allow the user to scan through the entire list of TV channels, extend beyond a safe area on the screen provided to accomodate a picture to overscan conditions. A direct access bar is arranged so as to cause the channel boxes to display numbers and logos of a selected group of channels when the user directs the pointing device at the area of the direct access bar that represents the selected group of channels.

Abstract: A motion sensor is mounted within a camera, and measures motion data such as translation, rotation, and zoom. The motion data is then associated with the video frame data captured by the camera. In some embodiments, the motion data is used to remove jitter in the frame data due to camera movement, and in some embodiments, the motion data is used to remove global motion from frame data before compression. Since the motion data is kept with the video frame data, the motion data is available during decompression of the video frames.
