The Most powerful DSP-based 1RU IP Codec

The Tieline Gateway introduces a new era in high-density multichannel IP codec streaming.

SmartStream PLUS redundant streaming

 

Connect multiple IP links to codecs and use SmartStream PLUS to stream simultaneous redundant data streams and deliver seamless redundancy when streaming over IP.

 

Bond multiple interfaces with Fuse-IP

 

Imagine the peace of mind knowing you can bond data links from different Telcos and let Tieline’s Fuse-IP technology automatically manage the data capability of each link!

 

 

The Gateway is ideal for:

- Audio contribution and managing multiple remotes.
- Studio-to-Transmitter Links.
- Network syndication of programming.

- Multi-channel links to remote studios.
- HTTP Icecast or Shoutcast streaming.

 

 

 

Flexible Audio Distribution

 

 

 

 

 The Gateway supports 16  mono or 8 stereo full-duplex audio streams. Gateway also supports flexible multi-unicasting and multicasting configurations for audio distribution.

 

 

 

- Stream up to 16 different multi-unicast audio streams to up to 80 endpoints in total.

 

- Stream up to 16 different multicast audio streams to unlimited endpoints over compatible networks
