Abstract: There is provided a motion-constrained AV1 encoding method and apparatus for tile-based streaming of an ultra-high definition image, which encodes an image such that the image can be decoded by integrating tile-based segmented images at a bit stream level without modifying an AV1 standard decoder. According to an embodiment of the present disclosure, the motion-constrained encoding method includes: limiting a motion prediction range based on a format and a size of an image; and predicting motion vectors regarding tiles constituting the image, based on the limited motion prediction range. Accordingly, a tile-based streaming service is possible through motion-constrained AV1 encoding of an ultra-high definition image (360 VR image or panorama image). In addition, a consumer electronic device is enabled to integrate and decode segmented images by using a single standard AV1 decoder.

Abstract: A method and an apparatus for calculating an offset of a Wheatstone bridge type sensor are described. The offset calculation method includes measuring resistances between nodes of a Wheatstone bridge type sensor, calculating an offset of the sensor using the measured resistances and providing information on the calculated offset. Accordingly, the offset of the Wheatstone bridge type sensor can be rapidly and easily calculated independently from the size of a bias current, and ultimately. Furthermore, time required to measure can be reduced and thus a sensor fabrication cost can be reduced, and also, mass production can be enhanced.
