Description

The invention relates to devices for transmitting an audio signal to wired radio subscribers and can be used to upgrade or replace the radio feeders of a city or rural broadcasting network.

A known system for transmitting audio data in digital format with compression on the main channels, designed to transmit analog audio signals with a frequency band of 40-15000 Hz and 50-7000 Hz, in high-frequency transmission systems [Pat. RF №2373651 C1, IPC Н04Н 20 / 02, s. 04/06/2007., Op. November 20, 2009.], which includes a reference circuit for the structural scheme of the main audio broadcasting with an end transmitting point, in which the signals are modulated to be transferred to the high-frequency spectrum of high-frequency transmission systems, and an end receiving point, in which the high-frequency signals are demodulated to extract audio signals broadcasting, moreover, the reference circuit and the corresponding structural circuit of the main channel, designed to transmit over the main network of audio broadcasting signals in digital Format in a standard 2048 kbit / s digital stream from 1 to 2 stereo channels or, respectively, from two to four mono channels corresponding to analog mono channels with a frequency band of 40-15000 Hz, transmit from more than six channels in digital format corresponding to analog channels with a frequency band of 40 -15000 Hz, by compressing the frequency spectrum by suppressing the frequency components of audio signals that do not carry basic information, and introducing certain quantization levels in the digital stream of digital, cable, microwave and optical fiber optic transmission systems.

In the known solution, as channels for the secondary distribution of sound broadcasting programs, the use of wire broadcasting channels for transmitting programs in the city (three-program receivers) and rural areas is allowed. At the same time, the low prospects of this type of communication are indicated. The task of replacing worn networks is not posed.

Similar disadvantages are inherent in the distance data transmission system [Pat. RF №74257 U1, IPC H04L 12/28, z. 10/01/2007., Op. 20.06.2008.], Including transmission means, information receiving means, sound source, format identification means, at least one computer. At the same time, the computer has a board for collecting audio data, encoding it into a network protocol and converting analog signals to a digital audio stream, while many consumers are included as receiving devices. In one of the options, it is possible to connect subscribers of urban broadcast networks. It should also be noted that this system implies the presence of feedback from the subscriber to the broadcasting studio, which undoubtedly complicates the system and requires the subscriber to have modern high-tech equipment.

Switchgear, which is part of a wired radio and television broadcasting system, Internet access, emergency alerts and communications with law enforcement [Pat. RF №94098 U1, IPC Н04М 11/00, G06F 15/16, з. 01/14/2010., Op. 05/10/2010.] Connected via a transformer to the radio feeder of a city or rural broadcasting network of wired broadcasting and including a command transmitter, a command receiver, a power converter, a carrier frequency detector, connected to the processor to isolate sound signals, separate interference and code transmission with reliability excluding false actuation on the actuator, through which the switchgear is connected to the speaker for notification, installed on the landing, outlets, ment of the apartments and the lines of radio outlets installed in the kitchen. According to its functionality, the switchgear is capable of providing an Internet connection (for which the system contains wired broadcast equipment connected to the Internet). This technical solution provides the possibility of using the existing wire broadcasting network for the latest types of communications, but does not take into account the need to maintain and restore obsolete networks in parallel with other, more modern and efficient, wired (cable) networks.

As a prototype of the selected switchgear audio broadcasting [US Pat. RF №108254 U1, IPC Н04М 20/00, з. 04/06/2011., Op. 09/10/2011.]. The prototype allows subscribers to receive wired radio programs (GOST 11515-91) in the usual format (for example, using three-program receivers, GOST 5961-89, GOST 18286-88) in case of failure or dismantling of the wire broadcasting network on the site from the broadcasting studio ( broadcasting equipment) to the subscriber’s house or apartment.

The prototype is installed in the house, connected to a wired broadcasting distribution network, contains a processor with the ability to extract, process, convert and transmit audio signals to subscribers, an input interface unit, with one of the following modules: Ethernet interface module [http: //ru.wikipedia. org / wiki / Ethernet], USB interface module [http://ru.wikipedia.org/wiki/USB], xDSL interface module [http://ru.wikipedia.org/wiki/XDSL], Wi-Fi interface module [http://ru.wikipedia.org/wiki/Wi-Fi], the WiMAX interface module [http://ru.wikipedia.org/wiki/WiMAX], the IMT-2000 interface module [http: //club.mabila .ua / wiki / IMT-2000], the interface module ca DVB-x [http://ru.wikipedia.org/wiki/DVB], VHF (FM) module [http://ru.wikipedia.org/wiki/УKB_CCIR]

However, the prototype does not take into account the possibility of using fiber-optic communication lines as a medium for signal transmission without the use of additional devices that convert optical signals into electric ones (for example, http://www.nateks.ru/products/index.php ? link = prod & id = 286) and the ability to use the transport medium of cellular and radio networks.

The objective of the utility model was to ensure that subscribers receive wired radio programs in the familiar format (for example, using three-program receivers) in the case of using fiber-optic communication lines to transmit a wired broadcast signal.

The problem is solved by the converter of wire broadcasting programs for installation in a house, connected to intra-apartment wire broadcasting networks containing a processor and configured to isolate, process, convert and transmit audio signals to subscribers, which, according to the proposal, contains an input interface unit containing at least , one of the following modules: PON [http://ru.wikipedia.org/wiki/PON], EPON [http://wiki.mvtom.ru/index.php/EPON], GEPON [http: // www. konturm.ru/tech.php?id=gepon], GPON [http://wiki.mvtom.ru/index.php/GPON], 10GEPON, APON [http://wiki.mvtom.ru/index.php/ APON], BPON [http://wiki.mvtom.ru/index.php / BPON], LTE [http://ru.wikipedia.org/wiki/3GPP_Long_Term_Evolution], GSM [http://ru.wikipedia.org/wiki/GSM], DRM [http://ru.wikipedia.org/ wiki / Digital_Radio_Mondiale].

The inventive utility model is illustrated by drawings.

Figure 1 presents the block diagram of the Converter; figure 2 and 3 presents examples of the integration of the device into the broadcast system through a data network based on fiber optic links or radio waves (DRM, GSM, LTE).

The converter of wire broadcasting programs 1 generally contains a digital signal processing unit 2 (motherboard, processor, RAM, ROM, digital-to-analog converter), an analog signal processing unit 3 (filters, modulators, adder, amplifiers), a protection and control unit 4 (sensors, matching transformer), control and adjustment unit 5, information input / output unit 6 (for example, by means of memory cards) and input interface unit 7.

The wired broadcast program converter 1 can be installed in a telecommunication cabinet 8 (fiber-optic communication line 11 to the building - see, for example, http://ru.wikipedia.org/wiki/FTTx) and is connected to the broadcasting platform 10 via fiber an optical communication line connected to the optical port of the input interface unit 7. The outputs of the device 1 (from the analog signal processing unit 3) are connected to the in-house wired broadcasting networks (wired broadcast subscriber 12).

Converter wired broadcasting works as follows.

The signals from the broadcasting equipment 9 through the platform 10 via a fiber-optic line 11 (or via radio waves) are fed to the converter 1. The essence of the device 1 is the receipt of a digital signal, processing and converting a digital signal into an analog signal of wire broadcasting (blocks 2 and 3) and supply of an analog signal to subscriber receivers of wire broadcasting 12. The protection and control unit 4 serves to protect against short circuits that may occur in the driveway and subscriber wiring. The use of sensors in the protection and control unit allows device 1, when removing a short circuit, to automatically resume issuing an analog signal to the building distribution network. The control unit and settings 5 is necessary to provide access for service personnel to the device for its settings and diagnostics on site (for connecting, for example, a laptop), in the absence of remote access to the device. Information input / output block 6 (optional) allows you to expand the functionality of device 1.

It should be noted that there is a large category of subscribers for whom a wired radio receiver remains a familiar and affordable means of communication. The proposed device will allow you to save this type of information without any additional costs on the part of subscribers, and will also reduce the costs of the service organization, especially in cases where the management of the same organization has modern communication lines.
