IP Audio Distribution

Using IP for Broadcast Audio Distribution…

Rapid improvements to IP network infrastructure have led to broadcasting over the public internet becoming a new paradigm for a growing number of radio engineers. Cost pressures and demands to improve the bottom line have also driven broadcasters away from leased lines, ISDN and satellite IP into terrestrial IP networks for STLs and audio distribution.

Tieline provides a range of IP solutions for distributing mission critical broadcast audio streams over LANs, WANs, the internet, satellite IP, 3G, 4G, Wi-MAX and Wi-Fi. Tieline multipoint IP audio solutions are ideal for:

  • Distributing programming between network affiliates or studios.
  • Sending multiple STL signals to different transmitter sites.
  • Sending program inserts to studios or affiliates.
  • Distributing audio from one site to multiple end points.
  • Sending voice tracks from remote studios, affiliates and other locations.

Multipoint Solutions Featuring Bidirectional Audio Streams

Tieline's Genie Distribution IP audio codec is the most feature-packed audio distribution codec with multiple levels of power, audio and network redundancy. It features a range of bidirectional audio distribution solutions which include:

  • 3 x bidirectional stereo connections, or
  • 2 x stereo and 2 x mono bidirectional connections, or
  • 1 x stereo and 4 x mono bidirectional connections, or
  • 6 x mono bidirectional connections.

Genie Distribution is also capable of distributing up to 6 channels of bidirectional mono audio between two codecs.

Expand Your Network with Multi-unicast IP Streams

Tieline IP multi-unicasts are the ideal way to modernize your network and reduce network infrastructure costs for broadcast audio distribution.

Multi-unicasting lets you create multiple connections from one broadcast codec to a specific group of codecs over LANs and WANs. This reduces capital investment by minimizing the number of codecs required when routing audio to several locations from a single point.

The transmitting multi-unicast codec specifies exactly which codecs will receive individual audio streams and dials them directly. This is different to multicasting, which is demand driven by any number of codecs and which is usually restricted to private LAN networks.

Tieline's latest multipoint IP innovations have created affordable new opportunities for streamlining IP audio across public and private IP networks using reliable, cost effective multi-unicast IP technologies. Tieline can assist you to implement these technologies and deliver flexible broadcast solutions to your network.

Genie Distribution is capable of up to 3 simultaneous mono or stereo multi-unicasts to a maximum of 50 endpoints in total.

Multicasting over Compatible IP Networks

Multicasting is an effective way to distribute audio to many locations with minimal IP configuration. It does not require a large amount of bandwidth at the codec transmitting the broadcast audio and it is particularly useful to broadcasters over private LANs that support multicast audio distribution within a network. Multicasts are ideal for:

  • Distributing high quality audio over broadcast LANs.
  • Distributing audio to multiple zones within a broadcast or non-broadcast network.
  • Distributing broadcast quality audio throughout environments like large buildings, airports, hotels and retail outlets.

Multicasting can also be a good way to set up permanent STL connections to affiliate codecs across private LANs that support multicast connections.

Genie Distribution supports up to 3 simultaneous mono/stereo multicasts over compatible IP networks to unlimited endpoints.

Tieline G5 ISDN module

Many broadcast networks are transitioning to IP but still require connectivity over ISDN or POTS/PSTN. Tieline's interchangeable connection modules provide the flexibility to connect anywhere, anytime, over your choice of connection transport as required.

Simply purchase optional Tieline G3 or G5 ISDN or POTS modules for your model of codec, insert them in the codec and you are ready to connect over ISDN, POTS or IP on demand. Click here to learn more about Tieline ISDN options.

SmartStream PLUS: The industry standard for broadcasting over the public internet

--------- SmartStream logo

Over a decade ago, as an IP audio pioneer, Tieline was the first major codec manufacturer to integrate SmartStream features such as Automated Jitter Buffer management, Forward Error Correction (FEC) and error concealment techniques in all IP codecs. These features dynamically respond to variable conditions over unmanaged IP networks like the public internet to ensure reliable streaming.

   --- SmartStream PLUS logo

Now SmartStream PLUS has revolutionised IP broadcasting by delivering the rock solid and reliable STL-grade audio quality you would expect over a T1/E1 link by using inexpensive unmanaged IP networks like the internet for STLs, audio distribution and remotes.

SmartStream PLUS technology allows you to stream simultaneous redundant data streams from dual Ethernet ports and deliver seamless redundancy when streaming over IP. This technology delivers your mission critical audio streams with rock solid reliability and best of all it's absolutely FREE in our Genie and Merlin range of codecs.

Compatibility and Interoperability, the key to flexible audio distribution...

All Tieline IP codecs are compatible with all major brands of IP codecs that have implemented the EBU N/ACIP tech 3326 specification, relating to interoperability over IP using SIP (Session Initiation Protocol).

All new generation Tieline codecs also support both IPv4 and IPv6 (Dual Stack) protocols, so broadcasters can be assured that they have made a smart investment for the future as new networks and technologies emerge over time.

When connecting over ISDN and X.21, Tieline codecs are compatible with all major brands of codecs using the popular G.722 and MPEG algorithms. Tieline codecs are also compatible over POTS/PSTN with Comrex* Matrix*, Access*, Vector* and Blue* codecs.

This means that if you have a Tieline codec in your studio with a LAN connection attached and a POTS/PSTN and ISDN module installed, you can accept calls from any ISDN codec, most IP codecs, most Comrex codecs and Tieline wireless enabled codecs - now that's compatible!
