ViA - the remote revolution

It’s time to reimagine outside broadcasting with the definitive remote codec of our generation. Tieline’s revolutionary ViA portable codec sets a new standard in wireless remote broadcasting and will fundamentally change the way you perform live remotes.

Picture yourself or an announcer taking your codec to a remote site, powering it up and tapping a single button on a colour touchscreen to get connected – just like making a phone call. Wouldn’t it be great if remotes were that simple? Well now they are – with ViA.


Remotes without limits

Our mission is to empower you with the technology to go live where no broadcaster has been before, and make it simpler. To achieve this, ViA delivers more IP choices and backup options than ever before.

Connect using dual Ethernet LAN ports, or 2 USB modems, or use the built-in Wi-Fi to connect over Wi-Fi. Use the touch screen to add Wi-Fi access points in seconds. Stream using a cell-phone Wi-Fi hotspot, or connect to hotels and other public Wi-Fi access points using the touch screen web-browser in a snap!

Insert an optional POTS or ISDN module and the codec is instantly transformed to connect over alternative network transports. This means you can configure primary and backup connections over different network transports as required, or use them as your IFB circuit.

Flexible Connections

ViA delivers all the flexible transport options you would expect from a professional codec. Select wired or wireless IP options, or choose to connect over ISDN or POTS.

Intuitive Interface

ViA has a 4.3 inch colour touch screen with menus designed to provide a familiar and intuitive user experience, similar to using a smartphone. Navigate and configure settings via the touch screen, or use front panel navigation buttons - the choice is yours. Brightness and adaptive light-sensor controls ensure the screen is readable in even the toughest light conditions.

Power on the GO!

ViA comes with a rechargeable Lithium-ion smart battery which delivers superior performance with up-to 6 ½ hours* of broadcast time. Extend battery performance with features such as configurable screen sleep time-out, screen brightness controls, plus automatic low battery power saving measures.

Wi-Fi Remotes on the Go

Built-in Wi-Fi and web browser connectivity expands your connection options from access points in hotels, fast food chains, or even a smartphone’s Wi-Fi hotspot. Use the touch screen to add Wi-Fi access points in seconds and stream program audio or your IFB circuit. Plus it's fully compatible with SmartStream PLUS and Fuse-IP. That's true flexibility.

Dual Cellular USB Modems

ViA supports a variety of pre-tested cellular USB modems out of the box. Simply insert a modem into a USB port and you're ready to go live in seconds! Bond data from multiple modems with Fuse-IP, or use two modems with SmartStream PLUS for dual redundant streaming.

Simplify use with Admin & Basic modes

Restrict user access to complicated network settings and take the hassle out of broadcasting forever. An administrator can configure 'Basic Mode' to simplify operation and present a subset of menus suitable for non-technical users. Configure the codec to automatically power-up in basic mode, then tap a program to go live in seconds.

Network Bonding with Fuse-IP

Use our proprietary Fuse-IP bonding technology to aggregate data from multiple IP transports such as LANs, cellular modems or Wi-Fi, and increase connection bandwidth. This improves connectivity, quality and redundancy.

Fuse-IP and SmartStream PLUS

With Tieline’s proprietary Fuse-IP data aggregation technology you can bond multiple IP interfaces, including options like:

• 2 USB modems, or

• On-board Wi-Fi, or

• Dual Ethernet LAN Ports.

Imagine the peace of mind knowing you can bond 2 USB modem data links from different Telcos and let Tieline’s Fuse-IP technology automatically manage the data capability of each link! Tieline understands flexibility is paramount for remotes, so you can even bond a USB modem with a Wi-Fi connection, or bond Ethernet connections.

ViA also includes Tieline’s SmartStream PLUS dual redundant streaming software, which has set the benchmark for redundant IP streaming over the public internet. Some manufacturers charge thousands of pounds for IP management software like SmartStream PLUS as an optional extra, however Tieline believes high performance and rock-solid reliability is an essential part of each and every broadcast, so you get it for FREE!

Nobody likes a traffic jam, least of all broadcasters dealing with IP packet congestion! With Tieline’s SmartStream PLUS and Fuse-IP technologies, as well as automated jitter buffer management and error correction strategies, you can be assured of trouble-free motoring on the information superhighway!

Stereo Program and IFB Communications

ViA seamlessly integrates with Tieline’s Merlin and Merlin PLUS audio codecs to transmit high fidelity, full duplex stereo program audio with a separate bidirectional IFB circuit. As an example, you could use a USB data modem to broadcast your main program feed and another USB modem or Wi-Fi to transmit your IFB circuit. Now that’s flexible!
