APPARATUS AND METHOD FOR DATA TRANSMISSION, APPARATUS AND METHOD FOR RECEIVING DATA, AND DATA TRANCEIVING SYSTEM

摘要

PURPOSE: A data transmission apparatus, data reception apparatus, and data transmission and reception system are provided to increase data transmission rates by determining data compression rates in real time. CONSTITUTION: A data management unit(150) allocates a transmission target file to plural sub data. A compression unit(160) compresses the allocated sub data. A transmission unit(170) transmits sub data including the compression data of the sub data by using parallel stream to a reception unit. A compression unit compresses data by comparing a compression rate between compressed data and the sub data.
