TVU One FHD and 4K Hardware Quick Start User Guide

Introduction, setup, and base operation

Build v7.0 and higher features two LCD console interfaces to choose from. Users can switch to the updated console from the LCD touchscreen.

Product overview

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 technology, ISX.

ISX is TVU’s ultimate transmission algorithm. The 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.

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

Charging the internal battery

To charge the internal battery without removing it from the encoder, connect the provided AC power adapter to the DC input on the unit and plug the other end of the adapter into an electrical outlet. The battery will then begin to charge. When the encoder is turned off, the battery will charge significantly faster (in approximately 3 hours).

The TVU One comes with an AC adapter. To charge the TVU One, connect the AC adapter as shown.

Power button status when charging

The TVU One displays the following power button status when the AC adapter is properly connected and the battery is charging:

The power button displays a steady green light when the unit is powered on and charging.
The power button light is off when the battery is charging and the unit is off. The LCD Screen displays the battery charging percentage.
The power button light is off when the battery is not charged or connected to the unit.

Note: An optional external TVU POWERPAC Li-Ion battery can extend the internal battery runtime. Refer to “TVU One backpack and battery mounting configurations” on page 5 for more information.

TVU POWERPAC Li-Ion batteries

The TVU POWERPAC Li-Ion battery mounts to the v-mount, g-mount, or gold-mount plates inside the backpack to extend the battery life of the transmitter while in the field.

The TVU POWERPAC 2 Li-Ion battery mounts to the v-mount plate inside the backpack to charge and extend the onboard battery life of the transmitter while in the field. The POWERPAC 2 is able to power your accessories and transmitter simultaneously with the integrated USB C, USB micro, and USB type A interface.

For more information, refer to the POWERPAC Quick Start User Guide.

Inserting SIM cards

The transmitter SIM card slots are designed to hold up to 6-Nano SIM (4ff) cards in three embedded modem slots. These SIM configurations are user-serviceable.

Note: The transmitter SIM card slots only accept Nano SIM (4ff) cards.

Complete the following steps to insert a SIM card into the embedded modem slot on the transmitter:

Note: The unit must be powered down before inserting a SIM card.

The TVU One FHD and 4K models feature three dual SIM card carriers for use with the internal modems. To remove a SIM card tray, gently push the end of the SIM tool into the round opening next to the SIM card tray until it clicks and slightly pops out. Carefully pull the dual SIM tray out of the slot.
Place 2 SIM cards into the dual nano SIM card tray as shown below and carefully slide the carrier into the embedded modem slot. Ensure the SIM cards stay in their respective carrier recesses during this process.

Turning off the TVU One

To turn off the TVU One, complete the following steps:

Press the power button once. A sliding button will display on the LCD touchscreen.
Slide the button from left to right to power down the unit.
