Description

This system relates to methods and devices for distributing information transmissions simultaneously among several receiving points along wired transmission lines or using radio waves and is used to broadcast a continuous stream of audio data (broadcasting) to any cities and towns using a global local area network (LAN), including satellite channels.

The level of technical use implies the organization of broadcasting, for example, from Orenburg to any region of Russia, as well as the continent.

To date, the principles of radio signal propagation, known since 1921, are actively used (see R. Hovsepyan, “History of the Latest Russian Journalism”, Moscow: Moscow State University 1999, pp. 73-89, 100-101, 120-124, 146) - electromagnetic radiation at various frequencies with the use of amplitude, frequency, phase and other modulations for a limited distance or zones included in the region of the reflected signal. Namely, broadcasting on the VHF band, on medium waves and wired urban broadcast networks. The disadvantages of this broadcasting system are as follows:

- The broadcast city wire network is obsolete and is gradually being reduced to nothing.

- Broadcasting on VHF is limited to a range of 20-30 km.

- Medium wave broadcasting is limited by sound quality.

- Difficulty in organizing and maintaining the transmission equipment.

A known system for transmitting and receiving audio / video and handwritten information in real time, adopted as a prototype (Patent No. 2302703, H04L 12/28, 2007.07.10).

The following system has been discovered in the known system related to the development and implementation of new technologies. This system has an excessive number of additional manipulations in establishing communications. Before its establishment, a bilateral agreement is necessary, i.e. the process is agreed in advance.

The task was: to develop a real-time distance data transmission system (DSS) more convenient for use, with an extended range, easier to organize broadcasting, including places where the radio signal was not transmitted.

In order to make SPDR more convenient for use, it is necessary to use a board for collecting and managing audio data in real time.

It is also proposed to install a special multifunctional computer program encoding audio data into a continuous stream of TCP / IP protocol. In order to achieve the indicated technical result in a known information transmission system including a transmission means, information receiving means, an audio signal source, format identification means, at least one computer, it is new that many consumers are included as receiving devices, including local area networks Internet providers, local computer networks of enterprises and towns, mobile phones, landline telephone network, satellite receivers, network radio speakers broadcasting of enterprises and municipalities, vehicles, cable television receivers, sound amplification equipment in open areas, radio receivers, WI FI computer-to-computer wireless transmitters, HF, VHF, FM transceivers.

The figure 1 shows the connection diagram of the finished functionally finished nodes broadcast studio.

The figure 2 presents a General diagram of the interaction of the broadcast studio in the global computing network.

Consider figure 1.

The source of the digital TCP / IP protocol is a broadcast studio. A continuous digital audio stream from a server is distributed to consumers via an Internet connection in a LAN at the first request of a listener located in one of the groups of signal recipients. The number of simultaneous listeners on the LAN channel can reach several thousand.

Broadcast studio 10 (see figure 1) consists of the following components:

1 Sources of analog audio signals;

2 Mixer, in which audio signals are mixed and adjusted in level;

3 uninterruptible power supplies;

4 computing machines of a Pentium IV class computer;

5 Boards for collecting audio data (sound adapter);

6 Management server program;

7 Standard network card with a fixed IP address;

8 Codecs of digital audio formats;

9 LAN cable connected to the LAN

The data transmission system at a distance works as follows.

The audio signals from group 1 are fed through the mixing console 2 to the audio data collection board 5.

From the board 5 and (or) from the codecs 8, the digitized signal is converted by the control program 6. The main function of the control server program 6 is the transcoding of continuous streams of digital data. This data, obtained by digital conversion of an analog signal (ADC data acquisition board 5) or finished digital audio format 8, is encoded into a sequence of TCP / IP protocol packets through a standard network card 7 via one or more ports, creating multichannel stereo audio streams.

Program 6 runs in the Windows environment with standard players such as Winamp, Aimp, Windows Media, using ready-made audio channel mixing resources.

The user, using standard sound-reproducing programs, at the request of a URL address known to him on the Internet or a local local network, is able to continuously listen to information. The amount of delay in delivering audio data depends on the bandwidth of the user's network with the provider and can be from 1 to 60 seconds.

From board 7, the encoded audio stream enters a network cable 9 connected to the global LAN.

Go to figure 2

The figure 2 presents a General diagram of the interaction of the broadcast studio in the global computing network.

A broadcast studio through the Global LAN can communicate in real time between consumers of the audio stream. End-listeners can send their information in text through the website of the broadcasting studio, through ISQ. By voice through a telephone connected to the broadcast studio’s remote, via Skype, through a headset or telephone via the Internet. Listeners can send CMC to a mobile phone broadcast studio. The operator of the broadcasting studio has the ability to display the voice of the caller on the air, and this can be heard by all subscribers connected to groups of consumers of the signal from the Global LAN. The result is a closed loop of communication with students, with good feedback.

The consumer is the provider's local network, consisting of remotely located computers that have sound reproducing devices (speakers, headphones). The mobile operator may be the consumer of the audio stream.

From the broadcasting studio, the signal is transmitted through the global LAN to the server of the mobile operator. Further, through the WAP portal is served on mobile phones of subscribers.

At the same time, using a physical communication line, the signal from the server can be connected to the city telephone network (GTS).

A GTS subscriber receives an Audio Stream in his landline telephone by dialing a short number. By pressing the appropriate phone buttons, the subscriber can select sound channels.

This technology is used to broadcast a continuous stream of audio data (broadcasting) to any cities and towns using the global local area network (LAN).

The level of technical use implies the organization of broadcasting, for example, from Orenburg or Moscow to any region of Russia, as well as the continent.

The proposed system for broadcasting a continuous stream of audio information from a broadcasting node to all settlements with access to a global LAN allows minimizing the cost of acquiring transmission equipment and energy consumption. Transfer is made by the TCP / IP protocol. The establishment of data reception occurs only at the request or need of the subscriber, requesting the IP address or DNS name (in the appropriate software, distributed freely on official sites). There are no restrictions in time and geography. The control technologies used in this system are easy to maintain and, despite the fact that they are high-tech, have an excellent combination of price / quality and are available for use by a graduate of a technical university. The proposed audio and video data transmission system allows you to receive listeners' calls and put them live in other cities. At the same time, in different time zones, you can receive data transmitted from the broadcast complex.

You can receive information from this system in mobile phones through the WAP portal, where there is no analog radio.

Using a receiving and transmitting server, you can communicate in hard-to-reach areas where radio waves do not pass through an optical fiber line or a regular telephone line.

Using this system, you can receive information in a regular landline telephone through a switch.

When using a radio channel, it is possible to communicate between local radio nodes in cities located at a reception distance and further relaying to the following networks.

If satellite equipment is used, the server of the transmitting satellite broadcasts over large areas.

The signal from the broadcast studio is fed to the server via the global LAN. From the server, the signal is transmitted to various receivers through the receiving server. In the case of using a satellite, the signal from the broadcasting studio via the transmitting satellite is delivered to the receiving satellite dish and then distributed to consumers. Signal consumers can be mobile operators, FM radio stations in different cities, Internet and cable television providers with their own networks.

Local subscribers with access to the global LAN can receive a signal from the data transmission system.

Subscribers of urban broadcast networks in different cities. In this case, the signal is taken either from the global LAN or from the satellite and fed into its network.

Open areas with sound amplifying equipment can be used to transmit data from the server through a radio channel or global LAN, as well as through a fixed landline telephone. On the radio nodes of any enterprises, data from the global LAN is received and relayed through their networks.

In the case of combining disparate local area networks of Internet providers into one subscriber of these networks can receive a signal and hear each other using SPDR.

This system can be perfectly used in the coverage of various elections, in broadcasting, as well as for communication between remote areas and cities.

At present, the distance data transmission system has been tested and is working successfully.
