Device for forming frame for data over cable service interface specification data transmission, has data slice forming block producing data-slice based on media access control-management data frame and user data frame

摘要

The device has a media access control (MAC)-frame classification block classifying a received MAC-frame in a MAC-management data frame and a user data frame. An input processing block (101) preprocesses the MAC-management data frame and the user data frame and receives a head end-reference unit. A data slice forming block (104) produces a data-slice based on the MAC-management data frame and the user data frame. The input processing block contains a synchronization correction block, which detects a synchronization message frame of the MAC-data frame. An independent claim is also included for a method for forming a frame for data over cable service interface specification data transmission.
