摘要： FIG. 1 shows an electronic program guide unique to viewer A grouped from an electronic program guide based on electronic program guide data; the program type is set in an (a) column and the display mode of each program is set in a (b) column. In FIG. 1, a news program is displayed in text and a music program is displayed in an icon of musical notes on a music sheet. A sports program is displayed in an icon of a bat and a ball. Since the music program and the sports program are thus displayed in such icon images of reminding the viewer of the program contents, the viewer A can quickly determine the program contents visually.

摘要： A communication device, particularly, a car-mounted information device, which makes it possible to obtain information of a transmitting source and of a receiving end linked to a navigation function relying upon end-to-end communication by using electronic mail among vehicles. The car-mounted information device comprises a cellular phone terminal connected to an external unit, a car navigation function, a modem function for transmitting and receiving data end to end between the vehicles via the cellular phone terminals, a mail transmitting/receiving function for transmitting and receiving the data using electronic mail, and a car navigation-linking function for processing the information of the electronic mail transmitted and received by linking the information to the car navigation function.

摘要： The present invention is directed to the provision of a radio receiver and of a radio receiving method that can reliably detect IBOC hybrid broadcast carrier waves. The radio receiver includes a tuning section for tuning to the frequency of a broadcast carrier wave, a detection section for detecting the signal level of the broadcast carrier wave at the frequency to which the tuning section has tuned, and a control section for detecting an IBOC hybrid broadcast carrier wave, based on a first signal level detected by the detection section by causing the tuning section to tune to a first frequency, a second signal level detected by the detection section by causing the tuning section to tune to a second frequency, and a third signal level detected by the detection section by causing the tuning section to tune to a third frequency. The radio receiving method is implemented in such a radio receiver.
