Rock Solid IP Audio STL Connections

With the phasing out of synchronous ISDN and POTS/PSTN leased line networks such around the world, thousands of broadcasters are turning to IP audio technologies and upgrading their Studio to Transmitter Links.

Tieline IP codecs can be used over:

• Public Internet Connections (WANs).
• Private LAN Connections.
• Dedicated or Shared Fiber Connections.
• Public or private WiMAX networks.
• A mix of the above-mentioned services.

Full Featured STL IP Audio Solutions

Tieline Commander G3 IP codecs are engineered to deliver rock solid and reliable audio over IP and they are capable of connecting over POTS/PSTN, ISDN, X.21, wireless 3G/4G and satellite networks. So with a Tieline G3 codec it is possible to take advantage of both new and old telecommunications transports as telcos and broadcast networks transition into new IP-based technologies.

Tieline Commander G3 rack mount codecs are ideal for STLs and deliver:

• Automatic network failover to POTS/PSTN, ISDN, X.21, IP or 3G/4G.
• Loss-tolerant algorithms delivering crystal clear audio with extremely low latency.
• Tieline's unique QoS Performance Engine Software for IP networks.
• Simultaneous analog and AES/EBU digital in/out.
• Real-time confidence monitoring.
• Full remote control from the studio.

Affordable, high quality STL IP audio solutions…  

Bridge-IT allows radio and television broadcasters to expand their IP network at a fraction of the cost of competing IP codecs, without compromising on quality or broadcast quality features.

It comes with 16 Bit 22kHz uncompressed linear audio at less than 12 ms encode delay, as well as MPEG Layer 2, G.711, G.722 and Tieline Music. Tieline MusicPLUS is also standard and provides 22 kHz mono and stereo with 20ms encode delay at under 100 Kbps, offering huge savings on your IP data bills and outstanding audio quality. AAC-LC and AAC-HE v1 and v2 decoders are also included as standard.

Bridge-IT is designed for desktop use or two units can be installed side-by-side in a purpose-built 1RU mounting bracket.

Applications:

Bridge-IT is perfect for a large range of broadcast and professional applications that include:

• Studio-to-Transmitter Link (STL) applications
• IP audio distribution
• Simple remote broadcast links
• Cable Head End IP Audio Distribution
• Low-latency audio over IP bridging solutions
• Multiple codec installations (2 codecs fit in 1 x 19” rack unit)

Tieline Delivers Steadfast and Dependable Audio over IP...

You may think that QoS (Quality of Service) that guarantees IP connection bandwidth is essential for STL links. While this is preferable, it is not always possible.

Tieline's QoS Performance Engine is a formidable broadcast tool in demanding IP broadcast situations. It is without doubt the benchmark technology for IP broadcasting excellence, combining superior network stability with uncompromising broadcast flexibility.

By responding to variable network conditions with agility and flexibility, it significantly improves connection reliability over lossy IP networks such as 3G cell-phone networks and the Internet.

This is extremely useful because broadcasters are usually unable to buy QoS (Quality of Service) over 3G networks, and it is difficult to obtain at most remote broadcast locations. With features such as Forward Error Correction (FEC) and automated jitter buffering, the QoS Performance Engine is a formidable broadcast tool in demanding IP broadcast situations.
