Device and method for controlling digital bidirectional communication |
| 摘要 |
An interface block (11) converts the format of input downstream data (STRM). A CPU (12) receives the format-converted data (DIF) and realizes the MAC function. A TEK process block (13) receives TEK process data (DTEK) obtained from the data (DIF), analyzes the data structure of the TEK process data, and performs decryption processing based on a result of the analysis.
