A method of compressing and restoring an Internet Protocol (IP) packet which is transmitted through a broadcast network is provided. According to the method, by using a characteristic of a transmission structure of a broadcast network, that is unlike ordinary packet switching communication networks, a field value that can be removed from a header part of an IP packet is determined. Then, the determined field value is removed from the header, and an IP packet having a header formed with the remaining field values is generated, thereby compressing the header of the IP packet more effectively compared to the header of the conventional static IP packet. In addition, by transmitting a compressed IP packet instead of a static IP packet which is periodically transmitted according to the conventional method, compatibility that the compression method can be used together with conventional compression methods is guaranteed. |
