Ethernet Broadcaster


Ethernet MP3/Ogg Vorbis Broadcaster streaming media server is a small embedded system used to transmit or receive an audio stream over Internet connection or in a LAN network. The board has a compact size, the dimensions are only 60x56mm and its height is less than 20mm. The broadcaster board can be used as module or inserted into an aluminum box with two plastic covers from which come out the audio, power and Ethernet connectors.

The Broadcaster board can operate as an integrated client for IP transmitted digital audio signal. It is a device designed to support MPEG-1 Layer 3 and Ogg Vorbis high quality compressed audio. The encoding and decoding takes place in real time by a powerful DSP processor and the output signal is both in digital (USB) and analog form. All these features allows you to quickly and effortlessly connect an audio systems to the Internet. Developed with the thought of easiness of use, Broadcaster can be managed through a standard Web browser, from: PC, PDA, Smartphone, etc. making it the best choice for professional and consumer use.


  • High quality MPEG-1, MPEG-3 and Ogg Vorbis real-time audio encoding and decoding;
  • 32 kHz, 44.1 kHz and 48 kHz sample rates support;
  • Support of all standard bitrates in CBR or VBR;
  • 4 LEDs on the front for a quick diagnostics;
  • 3 user programmable push buttons;
  • USB Host connector for Mass storage advantages;
  • IP address announcer at startup or discoverable through BroadcasterDiscovwerer.jar;
  • Static or DHCP automatically assigning Network Settings;
  • Easy setup via a standard web browser (HTML5 and javascript is required);
  • UPnP for easy discovery in Local Networks;
  • Shoutcast / Icecast compatible TCP/IP stream;
  • Auto switching to another server in the event of a connection loss (next release);
  • Analog Audio Output (1 x 3.5mm jack);
  • Analog Audio Input (1 x 3.5mm jack);
  • RJ-45 Ethernet connector.

The board can be used to transmit alarm messages in a natural park or in a factory, or to broadcast your themed radio station in a shopping center or at home. To see all possible combinations you can read the usage scenarios.

How to locate your board in a LAN

A PC Java application used to discover Broadcaster boards

To locate a board inside a LAN, you can download and use the simple application for PC (written in Java) nominated BroadcasterDiscovwerer.jar. The application shows the boards found in a table with four columns, the first show the IP address (, the second the NetBIOS name (BROADCASTER1), the third shows the MAC address (00-04-A3-F4-63-CF) and the last column displays the power event. The table have dynamic link, clicking on a row you'll be redirected to home page of the associated board.


Broadcaster board usage scenarios

Ethernet Broadcaster Home view

The Broadcaster board is compatible with many standard streaming media protocols, like IceCast or SHOUTCast. For this reason the audio stream can be create from two or more Broadcaster boards or from a computer to other boards or viceversa. The board has been well tested in unicast or broadcast streaming with VLC Media Player and some others player, but it is also compatible with the major web radios that transmit in MP3 or Ogg Vorbis format. Through the special web pages contained into the internal Flash of the Broadcaster board you can configure the differents mode to operate. The home page associated to IP address of the board has a free access, instead the settings pages need the administration credentials. The default administrator credentials are: admin and password. To prevent unwanted access you need to change the default settings since the first use.

There are at least four standards modes to operate in TCP mode and two standards modes in UDP.

In TCP mode, also known as Point-to-Point Unicast stream, there are the following scenarios:

  1. Single audio stream from one board (Server) to another board (Client), guide;
    Unicast stream: from Broadcaster to Broadcaster
  2. VLC Media Player as Transmitter (Server) guide and:
      1. one or more boards as Receivers (Clients) guide, and/or
      2. one or more instances of VLC Media Player as Receivers (Clients) guide.
    Unicast stream: from VLC to any
  3. One board as Transmitter (Server) guide and one instance of VLC Media Player as Receiver (Client) guide.
    Unicast stream: from Broadcaster to VLC
  4. A WebRadio as Transmitter (Server) and one or more boards as Receivers (Clients).
    Unicast stream: from Web Radio to any

In UDP mode, also known as Point-to-Multipoint Broadcas tstream, there are the following scenarios:

  1. Broadcast audio stream from one board as Transmitter (Server) guide, and:
      1. one or more boards as Receivers (Clients), and/or
      2. one or more instances of VLC Media Player as Receivers (Clients).

    Multicast stream: from Broadcaster to any
  2. VLC Media Player as Transmitter (Server) guide, and:
      1. one or more boards as Receivers (Clients), guide and/or
      2. one or more instances of VLC Media Player as Receivers (Clients), guide.

    Multicast stream: from VLC to any

Otherwise, for special needs you can ask a firmware customization related to your scenario.

All scenarios may include only Broadcaster boards or even computer with VLC Media Player.
