Abstract
Abstract A receiver such as a liquid crystal display television receiver, which a user carries with him, is used for learning at sight which television stations at a destination supply broadcasting service. The receiver performs automatic tuning operation of television signal waves to search available television channels, stores searched available television channels in a memory device, and displays a list of the available stored television channels. The receiver displays the available television channels stored in the memory device, and successively receives the available television channels, thereby displaying the television programs for a predetermined period. The receiver is equipped with a memory in which local areas, local television stations in the areas, frequency data and network relations between key stations and the local television stations are memorized. When an area memorized in the memory is designated, a station-selecting guide information is displayed, which indicates a network relation between the local television stations and the key stations. The receiver selects an arbitrary television station and detect the signal receiving intensity, and stores data of the selected television station and the relevant signal receiving intensity in the memory device. The receiver displays a channel number and frequency data of the selected television station in a displaying manner associated with the detected signal receiving intensity.
