  • Data transmission and data receiving apparatus that obtains file differences during transmission
    Patent number: 6434623
    Abstract: A data file recording medium stores data files which are an object of transmission and reception. A data file includes data, information as to data volume of the data, and a program having a data volume comparison processing and a data integration processing. The program may include additionally a data expanding processing, in the event that the data is a compression format of data. Such a data file is transferred between a data transmission apparatus and a data receiving apparatus. At the receiving end, a data volume comparison processing is effected to compare data volume as to received data of the data to be transmitted with data volume represented by the data volume information. If the data is in short supply, an amount of missing data is informed to the data transmission apparatus. The data transmission apparatus transmits a data file including data involved in only the missed out portion.
