Abstract: A data transmission method and apparatus, which can improve transmission efficiency and securely perform communication without increasing the bandwidth of encrypted data in an environment in which a transmission success rate for encrypted data is changeable depending on the quality of a network. In the method, a network quality of a channel is measured, and a lossy compression scheme or a lossless compression scheme is selected depending on results of measurement. Original data to be transmitted is compressed so that the original data is compressed using the selected compression scheme. Compressed data is encrypted. ECC encoding is performed on encrypted data, and ECC-encoded data is interleaved.

Abstract: A multi-frame data processing apparatus and method using frame disassembly is provided. The multi-frame data apparatus includes a data communication unit, a frame processing unit, and a data processing unit The data communication unit receives a transmission signal from a Line Adaptation Unit (LAU). The frame processing unit disassembles each frame of the transmission signal and acquires information data that is included in the transmission signal. The data processing unit transfers the information data to an Algorithm Processing Unit (APU), and acquires processed information data that is obtained by processing the information data via the APU based on a corresponding algorithm.
