Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 本発明は、衛星放送移動体受信装置に関する もので、衛星放送電波遮断時に発生する“ボツ音”ノイ ズを消去することを目的とする。 【構成】 衛星放送電波を受信して選局、復調した広域 周波数成分から、衛星放送電波が遮られた時の状態をい ち早く、CN比で検出し、CN比が低くなってPCMデ ータ信号が誤り、データの再生が出来なくなる前のレベ ルになった場合に、音声出力信号にミュートをかける。 【効果】 自動車や電車等の移動体上で、衛星放送電波 が遮られるたびに発生する“ボツ音”が消去でき自然で 違和感のない衛星放送受信ができる。 (57) [Summary] [Object] The present invention relates to a satellite broadcast mobile receiver, and an object thereof is to eliminate "click noise" noise generated when the satellite broadcast radio wave is cut off. [Structure] From the wideband frequency component that received and tuned to and demodulated satellite broadcast radio waves, the condition when the satellite broadcast radio waves were interrupted was quickly detected by the CN ratio, and the CN ratio became low and the PCM data signal was erroneous. , Mute the audio output signal when the level reaches the level before the data cannot be reproduced. [Effect] On mobiles such as automobiles and trains, the "click noise" generated each time the satellite broadcast radio waves are blocked can be eliminated, and natural and comfortable satellite broadcast reception can be performed.
