PURPOSE: A TS(MEPG2 Transport Stream) signal monitoring device using an FPGA(Field-Programmable Gate Array) is provided to have high reliability and stability even though the operation lasts for 24 hours. CONSTITUTION: An FPGA element(10) analyzes the malfunction of a TS signal by detecting one or more of a sync byte, a null packet, PSIP(Program and System Information), or PSI(Program Specific Information) received from a broadcast program supplier. A display unit(80) receives the information detected by the FPGA element. The display unit displays the received information as channel information of the TS signal.
