TVU One TM1000v3 FHD and 4K Software Quick Start User Guide

Introduction and Pack preparation

Note: The contents and features in this software user guide is compatible with TM1000 V3 FHD / V3 4K v7.3 and higher (Linux R) and v6.5 and higher (Windows R).

TVU One 4K delivers high-definition picture quality with 0.3-second latency at 3 Mbps. The TVU One FHD and 4K transmitters use the H.265/HEVC or H.264 encoding and compression standard to deliver greater data efficiency and transmission stability.

The H.265 hardware encoding chip delivers full broadcast quality in 4K, 10-bit true 60 fps video at as low as 3 Mbps with proven patented Inverse StatMux Plus technology, ISX.

ISX is the ultimate transmission algorithm. TVU One 4K uses less data and combats packet loss to achieve transmissions with virtually zero latency, down to 0.3 seconds, even in a moving vehicle or when going live in 4K. The TVU One FHD transmitter can also transmit live 1080p-60 at as low as 800 Kbps. ISX offers better utilization of available bandwidth in congested/low-signal areas and has extremely low latency as low as 0.3 seconds on cellular.

Both TVU One transmitter models simultaneously aggregate up to 12 data connections and can obtain bandwidth from anywhere: cellular 3G/4G/5G, WiFi, Ethernet, or satellite.

The TVU One 4K and FHD models have 100% more battery life than their predecessors. The TVU One FHD can communicate without latency using IFB and bidirectional VoIP between the studio and the field operator.

Real-time dual encoding allows you to go live under any network conditions by simultaneously recording a full HD copy of your video for later download.

Before you begin

Before using your TVU One transmitter, refer to the latest TVU One FHD and 4K Hardware Quick Start User Guide to set up the hardware and identify the devices you intend to use with the unit, including cameras, cables, power sources, modems, TVU services, and unit accessories.

TVU One software builds (v6.8.2, v7.0, and higher) support the RVF adapter and can be controlled using the LCD touchscreen. It includes an RVF option to support viewing return video feeds from an iPhone or iPad. Refer to the TVU One data sheet for more features.

Builds prior to v8.2 featured two LCD console interfaces to choose from.
