    摘要: A frame coding unit (13) generates individual picture signal information from a moving picture signal Vin, and outputs a frame code value InfVal_F which is a numeric value to be obtained as a result of coding picture signal information of each frame. A variable length coding unit (16) decomposes the frame code value InfVal_F into unit frame code values Val_F which are basic units of coding, converts the unit frame code values Val_F, into frame code words Code_F using only a single code table (16a), and constructs a frame stream by combining the converted frame code words Code_F. A multiplexing unit (17) multiplexes a header stream which is constructed through a method equivalent to a conventional method and the frame stream, and constructs a picture coded signal Str.

    摘要: An error correction coding system employs a single check symbol from an arbitrary sequence of information symbols to provide single error correction at the symbol level. The sequence of information symbols may in fact also be arbitrarily long. The coding system of the present invention provides both a method and apparatus for encoding the check symbol and a method and apparatus for error correction based upon the single coded symbol character. The system is particularly applicable for use in conjunction with bar code recognition systems but is in fact applicable to a broad range of coding systems, including optical character recognition and ordinary alphanumeric codes.

    摘要: Die Erfindung betrifft ein Verfahren in einem Computersystem zur Umcodierung einer codierten Zwischenvariablen (z) in eine umcodierte Ergebnisvariable (z'), wobei ein Produkt durch eine Multiplikation einer Eingangskonstanten (A) mit einer zu codierenden Eingangsvariablen (xf) gebildet wird, und die codierte Zwischenvariable (z) zumindest mittels dieses Produkts gebildet wird und wobei ein multiplikatives Inverses (A -1 ) von der Eingangskonstanten (A) bestimmt wird und das multiplikative Inverse (A -1 ) auf die codierte Zwischenvariable (z) angewandt wird, so dass kein uncodiertes oder teilweise uncodiertes Zwischenresultat (R1,R2,R3) entsteht und/oder in welchem die potentiell in der codierten Zwischenvariablen (z) enthaltene Fehlerinformation nach wie vor erkennbar ist.
    Weiterhin betrifft die Erfindung ein Computerprogramm sowie eine Datenverarbeitungsanlage.
