TVU G-Link Software feature User Guide

TVU G-Link software feature is an Internet-based, licensed solution for point-to-point live transmission that provides an affordable way of sharing live video between two locations. The G-Link software feature allows a receiver to transmit video to and from another G-Link receiver (point-to-point) for bidirectional transmission. The TVU G-Link software feature is added to the existing VS3100, VS3200, VS3500, and VS3600 server Web interface and is accessed and enabled in the Feature Control menu.

The TVU Server is the primary hardware component of TVU G-Link. With the G-Link software license, two servers can simultaneously send and receive a broadcast-quality video feed to/from each other. A TVU Server with the TVU G-Link software license takes a variety of incoming video types and formats, including incoming TVU One and TVU Anywhere transmissions, SDI input, and external IP sources. A TVU Server with a TVU G-Link software license also outputs in SDI and various IP formats in high resolution and can send feeds directly to social media platforms such as YouTube and Facebook via an optional IP streaming software.

Note: Prior authorization for the G-Link feature is required by the TVU Support team at support@tvunetworks.com.

Features

The TVU G-Link software feature enables TVU Servers to send and receive video with another dedicated G-Link software-enabled TVU Server.

TVU G-Link works with other TVU Products, including AP ENPS Integration, TVU Analytics, TVU Booking Service, TVU MediaMind, and TVU Producer. Also, A TVU Server with the TVU G-Link software license can be easily upgraded with a TVU Grid service license and subscription.

• TVU G-Link software is reliable, easy to use, and affordable.
• TVU G-Link is designed to work with commodity internet.
• SDI delivery with a wide variety of IP-based inputs and outputs.
• It supports up to two bidirectional links (between two locations) or four unidirectional links (between two locations).
• Controllable via an intuitive and web-based management platform.

Enabling the G-Link feature for LinuxR allows users to:

• Set bitrate, codec, and port of the G-Link encoder
• Add a G-Link source to the receiver
• Remove a G-Link source from the receiver
