Abstract
A tuner receiving system, a control unit for controlling a tuner receiving operation, a computer readable storage medium, and a method of receiving radio waves by using a tuner, are disclosed. The tuner receiving system outputs video and audio signals by processing the signals sent out when communication is established between a tuner unit for receiving radio waves from external sources and a capture card or the like. The main part of the system or the control unit discriminates the type of the tuner included in the tuner unit, based on a control signal output from the tuner unit after the start of the communication between the tuner unit and the communication interface unit, and displays a receiving station corresponding to a channel receivable by the tuner, in accordance with the type of the tuner and information from the communication interface unit.
