Abstract: 1. Portable system karaoke comprising a portable transmitting device further integrating the audio signals control processor, the first input of which is connected to a constant memory for a data storage of musical accompaniment and corresponding numbers as the digital signals, second input-to a matrix of switches, and the first output-to an input of the liquid crystal display, a video signals control processor, the first input of which is connected to a permanent memory for storage of background images and corresponding numbers as digital signals, and the second input-to a matrix of switches, a voice signals processor connected with internal and external microphones, and a mixer, the first input of which through an audio card is connected to an output of the audio signals control processor, the second input is connected to an output of the voice signals processor, and the first output-to an input of the modulated high-frequency radio signals generator connected to an aerial, television receivers capable of reception of modulated high-frequency radio signals generated in the transmitting device at the aerial input, distinguished by that the low-frequency television signals generator is installed into the transmitting device, at that the third input of a mixer is connected to an output of the video signals control processor, and the second output-with an input of the low-frequency television signals generator, the output of which is connected to video inputs of, at least, a part of television receivers by means of a cable. 2. A system according to claim 1, distinguished by that the portable transmitting device is encased into embodiment adapted for convenient grasp, operation and control by the singer inside which or on which all fixed compound units of the transmitting device are placed. 3. A system according to claims 1 or 2, distinguished by that cartridges with musical accompaniment and cartridges with the background images are installed into the transmitting device, the said cartridges being placed into separate slots to be capable of connection to the third inputs of the audio signals control processor and the video signals control processor accordingly. 4. A system according to claim 3, distinguished by that cartridges are legally authorized and protected from the non-authorized access by the authorized identifying and coding key device with the password of access, at that interconnected and connected with a cartridge interface socket microcircuits for storage of the downloaded data of musical accompaniment or background images are fixed in each cartridge and the authorized identifying and coding key device with the access password for prevention of the non-authorized access to the data stored in the READ-ONLY STORAGE of a cartridge and for identification of belonging of a cartridge to a certain set. 5. A system according to claim 1 or 2, distinguished by that the voice signals control processor is made and programmed to be capable of adjustment of height of tone, a rhythm, tempo, a delay of a sound, a level of an echo, artificial reverberation and volume of performance.
