MOBILE KARAOKE SYSTEM, METHOD USED PROVIDE ELECTROMAGNETIC COMPATIBILITY FOR MOBILE KARAOKE SYSTEM, MOBILE WIRELESS TRANSMITTING DEVICE FOR IT, CARTRIDGE FOR IT, METHOD USED TO PREVENT USAGE OF UNAUTHORIZED CARTRIDGE IN IT AND METHOD TO PREVENT UNAUTHORIZED ACCESSED TO THE DATA STORED IN IT
Mobile karaoke system shall mix signal from external audio input, such asvoice of asinger who performs a song to a microphone, with musical accompaniment datathat is pre-stored in ROM package and generates a signal for transmission to a radio. Thespecificfeature of this technical approach is that the mobile wireless transmitter forkaraoke systemshall be upgraded with auxiliary decoder for communication with cartridge viainterfaceconnector, and the cartridge is equipped with key identification and codingdevice that islinked to the Read-Only-Memory and can communicate with auxiliary decoder ofthetransmitter via interface connector. Transmission to the receiver shall bebased either onoptical signal, or ultrasonic acoustic signal, or radio frequency signal,which is transmittedeither via electric and/or magnetic near field of antenna while radio wavesemission is beingsuppressed, or while using such emission within vacant allocated band. Thissignal isconverted at the point of reception into broadcast frequency band with furtherreception ofthis signal by standard home radio. Due to the above said, there shall be nopossibility ofunauthorized access to the data that is stored in cartridge ROM, besides,unauthorized (pirate)cartridges can not be used for karaoke system, therefore, the rights of musiccomposers andthe rights of legal owners of intellectual property shall be observed.
