Tieline ViA Remote Codec




Remotes without limits

Tieline’s 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 chipset 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.
