    • 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.
    • 提供了通过广播网络传输的压缩和恢复因特网协议(IP)分组的方法。 根据该方法,通过使用与普通分组交换通信网络不同的广播网络的发送结构的特征,可以确定可以从IP分组的报头部分去除的场值。 然后,从标题中移除所确定的字段值,并且生成具有由剩余字段值形成的报头的IP分组,从而比传统静态IP分组的报头更有效地压缩IP分组的报头。 此外,通过发送压缩IP分组而不是根据常规方法周期性地发送的静态IP分组,保证压缩方法可以与常规压缩方法一起使用的兼容性。
