Abstract: In a hybrid codec apparatus for data broadcasting, an encoder divides a source file into N sections, generates N principal encoded data after coding on a first finite field and k additional encoded data after coding on a second finite field, then transmits a group of coefficient encoded data and the N+k encoded data to a decoder. The decoder merges the group of coefficient encoded data and the N+k encoded data, and decodes the N principal encoded data on the first finite field. When the decoder fails to decode the N principal encoded data, the decoder uses the k additional encoded data to assist the data decoding on the second finite field. After the decoding, a recovered source file is produced.

Abstract: An exemplary embodiment provides a method for swing result deduction and posture correction. The method includes performing a coordinate transformation between a sensor frame and an earth frame, deducting the swing result according to at least one piece of sensor information and a swing result deduction analysis, and providing a posture correction advice according to at least one piece of sensor information and a posture correction analysis.

Abstract: A method and a system for motion tracking, capable of tracking a trajectory of a movable object by an architecture having at least three accelerometers arranged in a predefined structure. The trajectory, displacement and rotational angle of the movable object are determined by ways of extrapolation, numerical calibration and vector transformation according to the acceleration signals detected by the at least three accelerometers.

Abstract: A real-time point of interest (POI) suggesting method is provided. In the method, present waiting time at several candidate POIs is obtained respectively right when an electronic apparatus is detected leaving an exit of a visited POI. Moving time for heading respectively for the candidate POIs from the visited POI is obtained. A suggested POI is selected from the candidate POIs according to the present waiting time and the moving time. Information of the suggested POI is transmitted to the electronic apparatus. The electronic apparatus outputs the information of the suggested POI. A computer readable storage medium with a computer program to execute the method and a real-time POI suggesting system are also provided.
