Abstract
The object of the invention is to offer a signal recording/playback device which contributes to the efficiency of analysis work when analyzing the cause of failures of mechanical equipment or the like. A synchronization separation section 2 extracts a horizontal synchronization signal and a video signal from a television signal. A temperature sensor 4 outputs an electrical signal proportional to the measured temperature. An S/H section 5 samples the electrical signal output by the temperature sensor 4 in synchronization with the horizontal synchronization signal. The video signal data and electrical signal data corresponding to the same horizontal synchronization signal are stored at the same address in a memory section 7. On the other hand, the video signal data and electrical signal data stored at the same address in the memory section 7 are simultaneously read in synchronization with a display synchronization signal output by a display synchronization signal generating section 8. A display control section 9 displays a video image reconstructed from the video signal data and measured values indicated by the electrical signal data on the same screen in synchronization with the display synchronization signal.
