The invention relates to a device (cable transmitters) to convert the video and audio signals in the radio frequency television signal, it “mixing” in the coaxial cable line for viewing on a television receiver, television tuners, computers, or other television devices used in multichannel systems videoaudioplayer.e for round the clock protection technical areas, entrances of residential buildings, stairwells adjacent to residential buildings in the areas, Parking lots, technical objects, monuments, etc.

Known systems videoaudioplayer.e containing the transmitting module that transmits the television signal through the telephone network using a modem), or by the television channel (US No. 4916737).

A device used in the system of multichannel videoaudioplayer.e and providing adaptation (agreement on inclusion and the means of reproduction devices, responsible for collecting, managing, processing information from systems televideoapparatury with standard household systems of recording and playback. The device pairing allows the system televideoapparatury to be able to use it as a household surveillance and protection. The television signal from each camera is fed to a device that can be negotiated to enable the playback (recording) and select an image from the N cameras with reproducing (TV) or recording (VCR) system. The block selection provides the coordination of selected channels using the control signal. The control unit

ensures the consistent inclusion of cameras and playback (recording) using the control signal. The device pairing provides the possibility of using domestic television and video equipment surveillance system (RU # 2129304, 1999).

The closest analogue is the system used as a surveillance tool for private residential and non-residential premises, open perimeters of warehouses, garages, administrative and industrial buildings, as well as intercoms and implemented her way. This system enables the use of coaxial wiring collective antenna for transmission of a television signal to the television sets of observation points without creating interference to the signals of television broadcasting stations. The system includes a TV, cable distributors, unit videoaudioplayer.e, the matching node of a television signal, the supply cable, power supply cable, and the power videoaudioplayer.e includes a video camera, microphone, video Converter, amplifier, modulator, the control filter, controlled filter, a local oscillator, and the matching node television signal includes a frequency-independent attenuator amplitude equalizer and block mixing signal (RU # 2149460, 2000).

Described above provides the closest analogue to the creation of television surveillance system using coaxial wiring collective antenna for transmission of one television signal into two or more household TVs. The closest analogue is not intended for the information of the information into a single point of protection (control) and does not provide for the reception of videohudozhnika from multiple cameras with microphones on one unit videoaudioplayer.e.

The problem solved by the invention, is to eliminate the disadvantages closest analogue.

The technical result that is achievable with the use of the invention is the provision of the transfer of images and sound in real time from multiple cameras with microphones through a single multi-channel system bus (coaxial cable) to the point of protection (control room). This proposed device is transmitting module provides empowerment system videoaudioplayer.e due to the transmission of one coaxial cable to 64 synchronized with the audio video signals (PAL color or black and white, microphone with AGC and adjust the frequency response and sensitivity).

Unlike the closest analogue, the proposed solution allows to use a single line, formed by a coaxial cable, for high-quality, simultaneous transmission to a single remote control signals from a few blocks videoaudioplayer.e located in different places.

The possibility of transferring multiple high-frequency signals on a single coaxial cable is known from the prior art. However, attempts to transfer from multiple cameras located at different distances from a single point of observation, encountered a number of technical difficulties, not to get quality signal transmission from multiple cameras on a single remote monitoring. In particular, these challenges include differences in the level of the sum signal and spectrum group of television signals in the unit of addition ranges (the adder), the system spurious emissions, giving interference to TV RF signals, standing higher in frequency than the television signal transmitted from any camcorder, misalignment of the wave resistance of the line and, as a consequence, the presence of crosstalk, reflections, attenuation and beating other signal line. In the presence of branched coaxial line requires a fairly complex and time-consuming calculation of voltage drop for different cable types and different lengths of line in order to ensure the feasibility and performance of a system.

We offer the transmitting module (cable transmitter) provides the possibility to increase the volume of the system videoaudioplayer.e simple connection of additional modules to the existing highway without investment in wired communications. This is accomplished due to the fact that all information flows are independent from each other, divided by the frequency in a single trunk coaxial cable, and the power to carry through the transmitting module to the Central wire of the coaxial cable is a single cable line.

Cable transmitter provides:

- the absence of mismatch of the wave resistance of the line and as a result, there is no crosstalk, reflections, attenuation and beating other signal line;

- the lack of noise at a higher frequency television signal line;

- ability to level with a group range of TV signals and as a consequence normal operation subsequent equipment highway (main television amplifiers, equalizers, dividers, couplers, etc.);

- the food itself, the television camera (camcorder), etc. from an arbitrary voltage in the line. There is no need for time-consuming calculation of voltage drop for different cable types and different lengths of the line;

- normal completion signal (carrier frequency) reverse control line, that is, signals from the consumer to the sources.

The technical result is achieved due to the fact that the input of the transmitting module - cable transmitter (driver highway to convert low-frequency videohudozhnika in the high-frequency modulated television signal) configured to connect to the output of the corresponding video camera and a microphone or microphone LF amplifier, and the output cable transmitter configured to connect to the input of the summation ranges, with cable transmitter includes a filtering unit system power supply is made with the possibility of connection to the Central conductor of the coaxial cable, which is the food system, and also includes sequentially connected TV modulator harmonic filter (HPF)amplifier , high frequency and attenuator.

The unit filtration system power supply includes a serially concatenated block barrier filter television signals for selecting a power supply unit protective filter feedback signals and the control line and the stabilizer, and the entrance of the filtration unit system power supply is connected to a Central residential line, which receives power from power source system. To the outlet of the filtration unit system power supply connected to the power system camera, microphone, microphone amplifier low frequency amplifier high frequency cable transmitter.
