Abstract: A method and a device for compensating for sensor drift are disclosed. A method for compensating for sensor drift, according to one embodiment, comprises the steps of: confirming the suitability of sensor data; defining a transformation model for transforming the sensor data; setting a loss function on the basis of the transformation model; and optimizing the transformation model on the basis of the loss function.

Abstract: A program guide data processing apparatus which can effectively use a frame_filter by effectively combining SCIDs of an SCID_filter (corresponding to the conventional PID_filter) and frame_headers of a frame_filter (correponding to the conventional section_filter), and which can reduce the size of a buffer for storing APG data by effectively using the buffer. The apparatus has the feature that the SCID_filter (PID_filter) and the frame_filter (section_filter) are in a multi-to-multi correspondence by providing at least one SCID corresponding to a respective header of the frame_filter, and the size of the buffer for storing the APG data is ‘(the number of APG_SCIDs)*(the size of the buffer set by a user: the minimum size whereby the buffer is not in full)’.
