Audio over IP is the next big remote broadcast revolution, and will soon be available through our G3 Commander and i-Mix platforms making them the world's first POTS, ISDN, GSM and IP-capable codecs.

Traditional broadcasting mediums such as ISDN, POTS and GSM will increasingly be replaced with broadband internet, Wi-Fi and high-speed cell phone networks.

Using Tieline codecs, you will have access to near-real time, high-quality audio from remote locations over the internet including DSL, Wi-Fi (802.11x), cable modems, high-speed data cell phones and satellite IP networks.

Configuring your studio for high quality, low cost remote broadcasts

The four steps, explained in detail on our website, are:

Step 1: Obtaining a wired, high-speed internet connection.
Step 2: Acquiring a Public (Static) IP address.
Step 3: Installing the Public IP and configuring the Network Address Translation.
Step 4: Connecting the codec (via LAN port).

See www.tieline.com/ip/ for details.

• Go completely wireless with a portable battery module or in-car power cable and a Wi-Fi bridge connected to the codec's LAN port.
• In most cases, unsecured Wi-Fi routers will auto-assign an IP address to the codec, allowing you instant access to the internet.
• If the venue has a DHCP LAN with broadband access, then connect the codec to the LAN port, dial the studio and you're on the air. It's that simple.

Upgrade options in the future
In this fast changing world, it is essential for broadcasters to choose a codec that offers a growth path to their evolving needs and offers investment protection against obsolescence.

As your needs evolve, you can significantly expand our codec's capability by adding network modules at a very low cost compared with buying additional dedicated codecs.

IP codec features at a glance:

• Connect your remote field codec to an unsecured DHCP wired DSL or Wi-Fi hotspot and dial back to the studio in SECONDS.
• Optimized for reliable operation over variable internet broadcasting conditions.
• A range of algorithms to deliver 7kHz - 15kHz mono and stereo at low bit rates plus uncompressed linear audio.
• Auto configuration of the remote codec from the dialing codec.
• Remote control your talents audio input from the studio. You don't need technical support in the field.
• Simultaneous broadcasting over IP and your choice of POTS, ISDN or GSM.

It’s one thing to report live from a stationary OB van, but it’s quite a different story from a moving car! Reporters at Omrop Fryslan, a European regional broadcaster are doing just that. Here’s how they do it!

Figure 2: Omrop Fryslan's reporters can connect to the studio with the push of a button in their VW Polo.

Omrop Fryslan's editorial staff had put up a challenge: Design a car in which reporters can set up a connection to the studio, walk in the vicinity of the car with a portable transmitter and operate as simply as possible - preferably using only one button!
“With this challenge in mind we started looking for a suitable solution,” said Martin Wijbenga, co-ordinator of audio technology at Omrop Fryslan.

The entire installation, in the trunk of a VW Polo, consists of a Tieline Commander G3 19”rack mount unit with POTS and GSM modules, a Motorola GM340 talk back unit to the portable transmitter, a Sennheiser VHF receiver and battery charger for the SER 20-4VHF portable transmitter and a Victron converter. The roof of the Polo carries three different antennae for the various systems.

Four hot keys on the Tieline codec's front panel were programmed so that with just a push of a button it connects to the studio and an internal relay in the codec switches on the return channel of the portable transmitter.

The first hot key dials a POTS connection without the extra “0.” The second one is pre-set with a “0” for PABXes. The third hot key dials the GSM network. The fourth hot key sets up a connection with the GSM network and activates the second audio input.

Mounted in the dashboard are a headphones output, audio input and a switch to dial a connection from the passenger seat. What more could a reporter wish for?

Reporting from a moving car has proven to be a major success and offers far better quality than a standard GSM cell phone. The reporters at Omrop Fryslan are more than pleased with their new car's possibilities!

Distance, speed, and location are no longer barriers.

It's the sportscasters dream machine. The Tieline i-Mix G3 is an advanced codec, commentary, communications, talkback and control interface featuring audio over POTS, ISDN, GSM - and soon IP!

We've combined the capability of SIX live remote broadcast products into ONE 16” x 9” box weighing just 4lb and offering 15kHz mono/stereo over ISDN, POTS, 7-15kHz over GSM - and soon IP!

The i-Mix G3 was designed by sports-radio and live-television-event broadcasting specialists to integrate communications, control and programming functions while significantly reducing the set up time, personnel, wiring and signal distribution costs and it does ALL of that!

The iMix G3 has six-input and three-output configurable digital mixing capability including five switchable mic/line inputs, one auxiliary and an analogue line input. An on-board telephone talkback interface is also included for taking live callers in the field.

The i-Mix features comprehensive control options, including a relay and RS-232 control system for local and remote control of equipment at either end of the codec link, plus control of the remote talent's audio input levels from the studio.

More options!

You can add additional POTS, ISDN and GSM codec modules into the expansion slot on the right hand side of the i-Mix G3 or unlock the internal IP streaming software module to increase programming, mixing and communications options.

The optional plug-in GSM module delivers 7.5kHz audio over standard GSM networks and up to 15kHz over High Speed Circuit Switched (HSCSD) GSM networks. Simply dial between the GSM enabled codec to a landline-enabled Tieline POTS codec. Use the battery module or vehicle power supply for a complete wireless solution.
