Digital Broadcasting Solutions

When it comes to terrestrial radio broadcasters, they expect the highest quality – and they expect it now. But ensuring network performance is easier said than done, especially if you are trying to control costs. Using Experior Networks all IP network, broadcasters are able to connect their IP-Audio networking equipment into our state of the art system to deliver high quality live radio broadcasts to customers while minimizing costs.

Experior Networks high bandwidth MPLS network enables broadcasters to carry multiple uncompressed channels of bi-directional analog or AES audio (as well as GPIO) over our wireless data links that operate outside the crowded 950 Mhz band. Our combination of fiber and wireless technologies offers a flexible and cost-effective solution for delivering advanced multimedia services to broadcasters including end to end network monitoring and unique multicast support. Our high bandwidth network offers broadcasters the ability to economically scale their operations with guaranteed Quality of Service(QoS).

IP Audio Overview

In an IP based network, individual audio sources are connected to audio nodes located in local studios and/or central server areas. These nodes convert incoming analog or AES/EBU signals to uncompressed 48 kHz, 24-bit digital audio, which is further converted to packet data suitable for Ethernet transmission. Each audio node input and output is assigned a unique IP address for identification and routing purposes.

Logic ports on each audio device are connected to GPIO nodes which convert these commands to packet data. Each node, connected to a local Ethernet switch, makes its audio and control data available to the network for subscription. Gigabit Ethernet or fiber-optic links between switches provide extremely high system capacity (many thousands of stereo signals per system).

Each studio's local Ethernet switch is connected to the other rooms via core switches or daisy-chain style. In this manner, control of all audio devices and their output streams are made available for on-demand use anywhere within the network. Since these audio streams are now in routable data form, automated software control of routing paths and switching configurations is possible. Entire routing networks can be remapped with a single mouse click. To simplify I/O even further, IP-Audio inter-faces can be built-in to broadcast equipment, allowing devices to send and receive audio channels to and from the network by simply connecting them to a local switch with an Ethernet cable.

Digital Broadcasting Reliability

When broadcasters convert their transmission to an IP based system, they are using the same technology that the largest corporate networks in the world are using. The same technology that underlies Voice over IP (VoIP) telephony that nearly 75% of all Fortune 100 companies are using. IP is now accepted as a universal transport for almost any kind of signal. You see it in television studios, business teleconferencing, government communications, banking, etc.

Entertainment and cable companies such as Viacom, Time-Warner, Cox and The Walt Disney Company have invested large sums of capital to ensure that their IP-based TV-on-demand systems will work as advertised. Cisco, Juniper Networks and other industry leading networking equipment vendors have invested billions to perfect and incorporate this technology in their mission-critical Ethernet switching equipment. Ethernet technology is in fact so reliable that it is projected US enterprises will spend more than $27 billion in Ethernet services over the next five years, growing from $2.4 billion in 2009 to $7.8 billion by 2014.

IP Audio Features and Benefits

The numerous operational benefits of Experior Networks’ high bandwidth transport services for IP-Audio networking include:

  • Lower Costs - With an IP infrastructure, all data, voice, and video applications can be integrated onto a single, secure network. New applications work reliably with existing applications because they are all based on the same protocol. Both short- and long-term savings are realized in several different areas, including materials, installation and maintenance. Users of IP-Audio networks typically report an installed cost 20% to 35% less than that of traditional hardwired studios;
  • Scalability - Since the underlying transport structure is standard switched Ethernet, expanding an IP-Audio network can be accomplished as easily as expanding a business computing network. All that’s required to add a new studio to the net is to connect its audio nodes to a local Ethernet switch that links to the core switch. The engineer can then quickly assign IP addresses to the new inputs using a standard Web browser;
  • Reliability – Experior Networks all IP network was engineered and designed with the reliability, redundancy and QoS that broadcasters demand. Our core MPLS network is managed and monitored 24/7/365 by industry experts to ensure your network is always live and service quality is never an issue.
