Method for conveying IP packet in broadcast network
2007
The present invention provides an IP message transmission method of broadcasting network, which can be used for effectively completing IP-based business in the multi-media broadcasting network, such as browsing, games and so on. In the method, the Mac address, IP and UDP header, and IP data payload are packaged in an IP load; the Mac address indication and IP header compression indication are packaged in an IP block head; the IP block head, the IP load and the CRC are packaged in a data unit; the length and the type of each data unit are recorded in a data segment head; a plurality of data units are packaged in the data segment; the data segment and other data to be transmitted are packaged and transmitted in a business channel; the terminal extracts each data unit after receiving the data segment, according to the length of each data unit in the head; the IP, the UDP header and the IP payload are extracted from the data unit so as to acquire the IP message. The length of the Mac address can be changed; the IP header can be compressed for transmission, thus the transmission efficiency is improved.
