  • Patent number: 10142433
    Abstract: A compression necessity determiner is configured to determine a necessity of compression of to-be-uploaded data to a server. A data compressor is configured to compress, when the compression necessity determiner determines that the compression of the to-be-uploaded data is necessary, the to-be-uploaded data in a predetermined scheme. When the compression necessity determiner determines that the compression of the to-be-uploaded data is unnecessary, a data sender sends data, in which a header is added to the to-be-uploaded data to the communication interface, and when the compression necessity determiner determines that the compression of the to-be-uploaded data is necessary, the data sender sends to the communication interface data in which a header, containing information indicating that the to-be-uploaded data is compressed data, is added to the to-be-uploaded data compressed by the data compressor.
