Description

Remote control with radio broadcast reception

The present invention relates to a remote control, and more particularly, to a remote control having a radio broadcast reception function formed in one unit by adding a function of radio broadcast reception to a remote control device for remotely controlling various sound devices.

In general, the remote control function for the remote control has emerged as an essential item due to the increasing demand and the variety of functions of home appliances such as television, audio, VCR, and the like. Such a remote controller is configured to, for example, output a command signal according to its operation in the case of a television as a pulse signal, and a receiver mounted at a predetermined position on the front panel of the television receives the same and decodes the command.

FIG. 1 is a flowchart illustrating a processing operation of a remote controller signal which is generally used. When the power is turned on, the system clears a memory such as a RAM and initializes each port. At this time, information about the channel, etc., performed just before the system is finished from the EEPROM inside the system can be read and output. For example, if you were watching channel 4 just before the power was turned off, the television would be on and at the same time channel 4 would be output to the screen.

Then, it is determined whether there is an input of a command through a manual key mounted on the front panel of the television, and if there is no input of a manual key, it is determined whether an input of a remote control key exists. At this time, if there is no input of the manual key and the remote control key, the system continuously performs the above determination process and enters the standby state.

On the other hand, if a manual key or a remote control key is present in the above operation, the input key is decoded to determine what command the command is. If the current state is the power on state, the execution routine of each key is performed. Jumps to perform the operation of each key and return again.

The conventional general remote controller operating as described above generally maintains a volume of a constant size, but a problem arises in that the function has no additional function other than the convenience of remote control of the corresponding electronic device.

An object of the present invention for solving the above problems is to add a radio broadcast reception function to a remote control device for remotely controlling various audio devices by combining a radio broadcast receiver and a remote controller which are separately configured in one configuration. It is to provide a remote control having a radio broadcast reception function formed integrally.
