The L1 signaling 202 provides necessary information in the physical layer such as information for connection or release with the DVB-NGH network. Reference numerals 203 and 204 denote an upper layer of the physical layer, and data transmitted from an upper layer is generated as a baseband (BB) frame through an encapsulation process.

A small CID (small CID) or a large CID (large CID) is used for RoHC compression information through the CID field among the fields of Table 2 above. Here, the small CID is one octet between 1-15, and the large CID is one or two octets between 1-16383. The size of the CID is determined by the following rule.

- When the CID value starts with '1110': RoHC compression information uses small CID, the context size is one octet, and the CID is four bits.

- If the CID value starts with '0': RoHC compression information is large CID, the context size is one octet, and the CID is 7 bits.

- When the CID value starts with '10': RoHC compression information uses a large CID, the context size is 2 octets, and the CID is 14 bits.

In the context profile field of Table 2, the range of the protocol used for compressing the IP stream is informed to the RoHC compression information, and the static chain byte field initializes the IP stream compressed by the RoHC compression information , And the size and structure of the static chain byte field depends on the context profile.
