Abstract: A method and device of generating an image stream with verification data are provided. The method includes the following steps. First, determine at least one pixel in a first image according to a first encoding parameter. Then, generate a timing data sequence associated with information about the correlation between the verification data and time points according to a second encoding parameter and the verification data. Next, modify a pixel value of the at least one pixel in the first image to generate a second image according to the verification data corresponding to one of the time points in the timing data sequence. Lastly, generate the image stream including the second image.

Abstract: A data encoding and decoding system including an encoding apparatus and a decoding apparatus is provided. The encoding apparatus is configured to patternize a data. The encoding apparatus displays the patternized data in a manner of dynamic twinkling. The patternized data twinkles in a predetermined frequency. The decoding apparatus is coupled to the encoding apparatus. The decoding apparatus is configured to capture the data which dynamically twinkles in a predetermined time period. The decoding apparatus performs a data processing operation on the captured data to identify the captured data. In addition, a data encoding and decoding method is also provided.

Abstract: A method and an apparatus for establishing a coordinate system and a data structure product are provided. The method includes following steps: obtaining at least one layer related to an arrangement of an indoor space to generate a layout pattern in a 2D or 3D model; obtaining locations of positioning devices located within the indoor space and labelling the locations in the layout pattern; dividing the layout pattern into multiple view tiles according to a unit area or a unit volume for displaying the layout pattern; dividing a portion of the layout pattern around the labelled positioning devices into multiple positioning tiles according to the labelled locations of the positioning devices; and selecting at least one representative point of the view tiles and the positioning tiles as a reference point to define a reference frame and establishing the coordinate system based on the reference frame.
