PURPOSE:To prevent confusion between visual and audible senses, by reproducing background music at the playback of character information, in a signal receiver broadcasting character information signals on a television signal. CONSTITUTION:In receiving normal television program sources, a switching circuit 23 is switched to a television side. When an index signal for fully fixed display is included in a reception data transmitted on a character broadcasting data bus 14, an input and output controlling circuit 21 applies a background music BGM start signal to a power supply 24 and a delay circuit 25 of a BGM generator 20. Thus, the switching circit 23 is switched to the BGM side, music information from a melody generator 22 is reproduced from a speaker 30 and the character information is pictured on a television screen. |
