Abstract: Provided herein is a sentence hiding and displaying system comprising: an image creating interface receiving an input of information on an original image, a plurality of sentences corresponding to the original image, and a language that needs to be hidden; an image creator configured to determine a sentence that needs to be hidden based on the plurality of sentences and the language that needs to be hidden, and to create on the original image an image where the sentence that needs to be hidden is hidden; a sentence display interface configured to receive an input of information on a language selected by a user; and a sentence extractor and displayer configured to parse a sentence expressed in the selected language of among sentences that need to be hidden based on the hidden image and the selected language, and to display the sentence expressed in the selected language.

Abstract translation: 本文提供了一种隐藏和显示系统，包括：图像创建界面，接收原始图像信息的输入，与原始图像对应的多个句子以及需要隐藏的语言; 被配置为基于所述多个句子和所述需要隐藏的语言来确定需要隐藏的句子的图像创建器，以及在所述原始图像上创建隐藏需要隐藏的句子的图像; 句子显示接口，被配置为接收由用户选择的语言的信息的输入; 以及句子提取器和显示器，被配置为基于所隐藏的图像和所选择的语言来解析需要隐藏的句子中以所选择的语言表达的句子，并且显示以所选择的语言表达的句子。

Abstract: Provided herein is a PLC synchronization method including allocating a predetermined value with respect to a plurality of modulation symbols depending on whether sum of squared magnitude of in-phase component and orthogonal component is arranged in a predetermined range, calculating first moving sum and second moving sum of a value allocated to the plurality of modulation symbols, and performing PLC (physical layer link channel) synchronization based on the plurality of modulation symbols having maximum value of the first moving sum and the second moving sum.
