摘要： According one embodiment, after receiving, as a received bit sequence, an information bit sequence which has been encoded for an error correction in the form of connecting an error correcting code to the outside of an LDPC code, the received bit sequence is subjected to the LDPC decoding, and then subjected to an error correction corresponding to the error correcting code. When the error correction corresponding to the error correcting code is impossible, a bit with low reliability is detected from the received bit sequence subjected to the LDPC decoding, and the bit is inverted, and then the received bit sequence with the inverted bit is subjected to an error correction corresponding to the error correcting code.

摘要： The present invention proposes a dot pattern on which code information and x and y coordinate information can be defined even if the dot pattern is extremely small, and proposes an information reproducing method and an information reproducing device based on the dot pattern. More specifically, a medium such as a printed material on which is formed a dot pattern portion by arranging in accordance with a given rule dots generated by a dot code generating algorithm in order to recognize various kinds of multimedia information is scanned as image data by scanning means. Then, the image data is converted into code data. Multimedia information corresponding to the code data is read out of storing means to be reproduced.

摘要： To achieve an information output device in which information of a medium disposed on a stage surface can be surely and efficiently read out, and a stage effect and a security are high. In the information output device, media are disposed on a stage surface in a state where the media are opposite to the stage surface, the media where dot patterns are printed on medium surfaces on the basis of a predetermined rule, the dot patterns are read by imaging units disposed in a space below the stage and converted into code values or coordinate values indicating the dot patterns from photographed images obtained by the imaging units, and information corresponding to the code values or the coordinate values is outputted. Further, light transmitting reading holes are respectively provided at a plurality of medium disposing locations on the stage surface, and the imaging units are disposed in the space below the stage corresponding the respective reading holes such that the imaging units photograph the medium surfaces of the media disposed on the reading holes.
