    Abstract: PURPOSE: An apparatus and a method for processing a timestamp using signature information in a physical layer are provided to improve accuracy by reducing a delay, jitter and uncertainness according to the performance of a timestamp in a physical layer. CONSTITUTION: A first timestamp processor(10) allocates signature information for indentifying a synchronization message to a transmitting message through a pseudo random number. A first timestamp processor verifies the signature information in a physical layer, and a second timestamp processor(20) verifies a pseudo random number of a message on the physical layer. Accordingly, the second timestamp processor discriminates whether or not the message is the synchronization message.

    Abstract translation: 目的:提供使用物理层中的签名信息来处理时间戳的装置和方法,以通过根据物理层中的时间戳的性能来减少延迟,抖动和不确定性来提高精度。 构成:第一时间戳处理器(10)通过伪随机数将用于识别同步消息的签名信息分配给发送消息。 第一时间戳处理器验证物理层中的签名信息,第二时间戳处理器(20)验证物理层上的消息的伪随机数。 因此,第二时间戳处理器判断消息是否是同步消息。
