A transmission/reception system includes a transmitter for transmitting pay information, and a plurality of receivers. The transmitter includes a service center for editing contents to be transmitted, and a transmitting station for receiving the contents from the service center and transmitting same. The plurality of receivers each include a mounting portion in which a storage element may be removably mounted. The storage element pre-stores charging information for permitting reception of the pay information and is sold at a predetermined cost. Each receiver determines whether it is allowed to receive and reproduce the pay information in accordance with the charging information stored in the storage element mounted in the mounting portion. When the storage element is purchased, the cost is remitted or electronically sent to one of the service center and an account of said service center. Another part of the cost is remitted to one of the transmitting station and an account of the transmitting station.

Broadcasting system, and charging system and method

A service information receiving apparatus for receiving pay service information and date data which is multiplexed on FM broadcast waves transmitted from an FM broadcasting station, wherein use end day data calculated on the basis of valid term relative value data stored in a detachable IC card installed in the service information receiving apparatus and the received date data is acquired and stored, and the stored use end date data and received date data are compared. The display of pay service information is permitted while both data do not coincide, and the display of pay service information is prohibited after both data have coincided.

Information transmission/reception system

A service information receiving device receives pay service information and year/month/day-of-month data, both multiplexed with FM broadcast radiowaves and transmitted from an FM broadcasting station. The device compares the use end date data, stored in an information storage medium which is detachable from the device, with the year/month/day-of-month data received by the device, and the device permits the display of the pay service information during the period in which these two sets of data disagree with each other, and after they have coincided with each other, inhibits the display of the pay service information.

An indication or image on a display unit is switched in response to changes in performance data of a tune which is being played automatically. Tone pitch data included in the performance data are detected, and the indication (image) on a display is switched in response to changes in the detected tone pitch data. Velocity data and tone color data in the performance data may be used in place of the tone pitch data. If a tune is automatically played based on a plurality of performance data which are simultaneously read out, the indication on the display is switched based on changes in either of the plurality of performance data. If switching data representing changes of rhythm of the tune is included in the performance data, the switching data are detected, and are used to change a way of switching the indication (image) on the display. The indication or image on the display may be switched at timings based on beats or strong beats or at timings of measures. If performance data for automatically playing a tune are input while a user of a musical instrument is playing the instrument, the indication or image on the display is switched based on the number of keys which the user operates simultaneously, touch data or tone area data.

A plurality of pad operating means for manual operation are provided on a keyboard panel of an electronic keyboard musical instrument. When an operator operates the pad operating means using the keyboard during melody play, an operation signal is supplied to a CPU, and a rhythm sound corresponding to the operated pad is generated under control of the CPU. An automatic sound signal generator is provided for generating and outputting sound signals according to a designated rhythm, and selectively stops such sound signal generation. A sounding system is provided for sounding the signals received thereby.
