Abstract

There are provided a TV recorder, a TV receiver, and a medium of storing a control program, which enable reliable recording of a TV program being broadcast in a channel used before switching while avoiding cumbersome operations. If information detected by an infrared camera indicates fluctuations in the number of TV viewers between before and after an instruction to change to a new display channel, a control section determines that the instruction to change to the new display channel is issued from a new TV viewer different from a TV viewer existing before the instruction is received, and makes a display signal output section output TV signals of the new display channel to a TV monitor and also makes a HDD record TV signals of the display channel used before the instruction to change to the new display channel is received.
