Setting panel – Control
The setting panel controls are located as shown below.
![Setting panel](https://www.tvunetworks.com/wp-content/uploads/2023/11/Setting-panel.png)
The setting panel includes the following controls and functions:
![Control setting panel](https://www.tvunetworks.com/wp-content/uploads/2023/11/Control-setting-panel.png)
(1) Delay control: To configure the live shot latency, adjust the slider or enter a value manually in the input box and press Save.
This value is always stable and will not change unless manually adjusted during transmission. Delays as low as 0.5 seconds should be routinely achievable in good bandwidth conditions. There is a relationship between lower delay and the amount of bandwidth consumed for error correction, so higher delays of 4 to 10 seconds are recommended for non-latency-sensitive transmissions.
(2) Bitrate control: The TVU server has a smart VBR scaling system. The unit automatically adjusts the bitrate to output the best quality picture based on the desired latency. To effectively take advantage of the smart VBR scaling system, set your desired latency and the maximum bitrate you want to utilize. The bitrate setting for 4K streaming is now supported up to 25 Mbps.
(3) Adaptive delay control (dynamic/fixed) for Grid only: Controls the dynamic buffering feature of Grid. When set to dynamic mode (recommended), the server automatically increases the stream buffer to ensure stable transmission. This selection maximizes stream stability but at the potential cost of increasing the delay/latency. The fixed mode will lock the Grid stream to a specific delay but allow errors if the setting is too aggressive. We recommend using dynamic mode for normal operations. Where fixed mode is enabled, the operator should pay extra attention to the stream stability with their given setting.
(4) VBR/CBR: The TVU server has a smart VBR scaling system.
Refer to Advanced operations for more information.
![Mode selection menu](https://www.tvunetworks.com/wp-content/uploads/2023/11/Mode-selection-menu.png)
(5) Preset selection menu (operational): Click the Select drop-down menu to view User’s 1 and 2 presets.
- User 1 & User 2: These are user definable presets. To program these, users right-click the preset they would like to define. Users can then name the preset, change the bitrate, manually set latency, or check Set Current, saving the current latency setting to that preset. Press Apply to program once finished.
Status panel – diagnostics
Many indicators are arranged vertically in the Status panel to help an operator make quality and troubleshooting decisions. Information such as error rate and line quality are displayed, and a quality histogram depicts the total transmission encoding bitrate over a period. The histogram’s scale can be changed by selecting a different display option on the drop-down menu. The status of the transmitter’s batteries is also displayed.
The Status panel diagnostics are located as shown below.
![Status panel diagnostics](https://www.tvunetworks.com/wp-content/uploads/2023/11/Status-panel-Diagnostics.png)
The Status panel includes the following controls and functions:
![Diagnostics panel](https://www.tvunetworks.com/wp-content/uploads/2024/03/Diagnostics-panel.png)
(1) Input and output formats: “Input” displays the video input format of the transmitter. “Output” displays the server output setting.
Note: The server output format follows the input format when the Input Match feature within Feature Control is enabled.
The TVU Pack input and server output should match. The server software is not intended to convert or adjust the resolution. In the event of a mismatch, the server will attempt a format conversion, which may result in losing video quality and removing closed captions from the transmission.
(2) IFB status: The IFB status and the IFB Signal display. The IFB signal has a strength meter that depicts the input level of the IFB.
(3) VoIP status: The VoIP Signal has a strength meter that depicts the input level.
(4) Refresh button: If the video displays as a black screen or pixelates heavily and does not recover automatically within 15 seconds, click the Refresh button to reset the video stream.
(5) Select button: The Select button opens the preset selection drop-down menu.
(6) Eco-Preview: The Economy Preview Timer Setting feature allows the operator to set the preview mode timer (in minutes). The operator can also set the Preview mode to remain, whereby the operator can manually exit.
Note: Refer to the “Advanced configuration” section for more information.
(7) Edit timer: Use the Edit time button to edit the Economy Preview setting.
![Quality histogram and link](https://www.tvunetworks.com/wp-content/uploads/2024/03/Quality-histogram-and-link.png)
(8) Audio level light display: The audio bars allow users to monitor your audio levels visually. This displays decibels relative to the server’s full-scale (dBFS) audio input level.
(9) Quality histogram/Quality link: The quality histogram below the Quality link displays a 5-minute aggregate histogram of the live transmission.
Click the Quality link to access the post-live histogram. The post-live histogram allows users to recall a histogram of a transmission and display it as a Web-based graph. The operator can review the post-live histogram overall performance of that transmission over a certain period.
Post-live histogram features: Users can look at a transmission that took place on a specific date and monitor the entirety of a live transmission in a “Post-Live histogram.” The automatic refresh time can be set to a desired length, and users can search for a specific transmitter by typing in the PID number of the transmitter.

TVU Linux server transmission – Going Live
Taking your transmission live involves selecting a source, starting a live session with a video source, setting the correct bitrate and delay, and tuning your shot.
Selecting a source
To select a source from the Web Receiver UI, complete the following steps:
- In the source panel, expand the source type, select thumbnail view, and click on the desired live source thumbnail.
![Source type panel](https://www.tvunetworks.com/wp-content/uploads/2023/11/Source-type-panel-2.png)
- After a source is selected, a red box will frame the thumbnail image.
Note: Selecting a transmitter that has a video thumbnail (live source), will start a live session.
![Video or live source selected thumbnail indicator](https://www.tvunetworks.com/wp-content/uploads/2023/03/Video-or-live-source-selected-thumbnail-indicator.png)
The source thumbnails will display using one of the following status indicators:
The following thumbnail indicates the video source is Offline.
![Offline thumbnail indicator](https://www.tvunetworks.com/wp-content/uploads/2023/03/Offline-thumbnail-indicator.png)
The following thumbnail indicates that the remote source is powered and connected, but no video input is detected.
![Connected with no video input thumbnail indicator](https://www.tvunetworks.com/wp-content/uploads/2023/03/Connected-with-no-video-input-thumbnail-indicator.png)
The following thumbnail indicates when a source is online and live video is detected.
![Connected and online with video input thumbnail indicator](https://www.tvunetworks.com/wp-content/uploads/2023/03/Connected-and-online-with-video-input-thumbnail-indicator.png)
The following thumbnail indicates that the video is a generic external source. Other external sources are SMPTE2022, YouTube, NDI, or SRT, with identifying thumbnail icons.
![Generic external source detected thumbnail indicator](https://www.tvunetworks.com/wp-content/uploads/2023/03/Generic-external-source-detected-thumbnail-indicator.png)
- If the live source was previously activated and then stopped, the thumbnail will continue to display with the thumbnail framed in red. To take the source live again, click the Live button.
Taking a shot live
To take the shot live, complete the following steps:
- Click the thumbnail in the source panel to start a live session with a source not already framed with a red box.
- Click the Live button to start a live session with a source framed with a red box.
- Set the bitrate, delay, and VBR/CBR settings.
Setting the variable bitrate (VBR) and delay
The two primary controls affecting the quality and latency of a live shot are the bitrate and delay sliders displayed in the Setting control panel.
![Receiver UI control panel](https://www.tvunetworks.com/wp-content/uploads/2024/03/Receiver-UI-Setting-control-panel.png)
In the Settings > General pop-up window, users can change the default buffer size from the 2-second default to 0.25 – 0.5 seconds for very stable networks. Other delay selections are available from 1 second up to 3.5 seconds.
To set or edit the bitrate and delay, complete the following steps:
- Delay: To configure the live shot latency, adjust the slider, manually enter a value in the input box, and click Apply.
This value is always stable and will not change unless manually adjusted during transmission. Delays as low as 0.5 seconds should be routinely achievable in good bandwidth conditions. There is a relationship between lower delay and the amount of bandwidth consumed for error correction, so higher delays of 4 to 10 seconds are recommended for non-latency-sensitive transmissions.
- Bitrate: Use the slider to select a value, or enter it manually into the input box, and click Apply.
A higher value will increase the pack’s encoding quality and transmission throughput (subject to bandwidth availability) to a maximum threshold of 10 Mbps. Bitrates above 5 Mbps should not be required except for fast or high-motion sports videos.
Note: Changes to the bitrate slider can be made during a live transmission without interrupting the shot. Adjusting the Delay setting during a live transmission will interrupt the video while the stream rebuffers.
- Click Settings and select General. Scroll down to Default Delay and Bitrate Setting. The Default Delay and Bitrate Settings display. The slider must be green “enabled” as shown.

Selecting VBR vs. CBR
The TVU system makes use of SmartVBR™ adaptive encoding technology to maximize the reliability of the live transmission. The encoder will detect the bandwidth available and adjust the encoding bitrate up to the maximum value set on the slider. If the SmartVBR detects a drop in available bandwidth, it will decrease the encoding resolution to keep the video stable and smooth.
Variable bitrate (VBR) mode
VBR is the default setting and should be used under most circumstances. Click the VBR drop-down menu above the bitrate slider to select or change the setting.
Constant bitrate (CBR) mode
In some circumstances, turning off the VBR logic and forcing the transmission to CBR mode may be desirable. The encoding will be locked to the configured bitrate in CBR mode regardless of available bandwidth. The most common application for this setting is with IP satellite systems with fixed bandwidth.
Tuning a shot
In a live interactive environment with ample bandwidth, normal operation would combine a high bitrate with a low delay for smooth, stable transmission. If the bandwidth is constrained and the transmission is not stable at the configured settings, the operator has two primary controls to affect the transmission:
- Increase the delay of the transmission. An increase in delay causes a reduction in the error correction overhead required for stability. A reduction in overhead frees up more available bandwidth for video quality. The delay can be increased from 0.5-second steps up to 10 seconds.
- A stepped increase of 0.5 seconds up to a maximum setting of a 10-second delay should be attempted.
- Suppose the nature of the transmission is especially delay sensitive, or the conditions are very challenging. In that case, bitrate reductions should be performed in steps of approximately 500 Kbps until stability is achieved.
Combining these two controls should allow the operator to routinely and reliably manage video streams from challenging environments.
Note: When transmitting a very low movement or still setting, the pack will adjust and use less data until movement is reintroduced. This is normal behavior.
The Eco Preview – Timer setting feature
The Economy Preview (Eco Preview) saves data usage by reducing the transmission rate to 500 Kbps while in preview mode. The transmission will revert to the previously set bitrate upon expiration or cancellation of the Eco Preview timer.
The Economy Preview button allows the operator to automatically set the Eco Preview mode timer (in minutes) to exit the Preview mode. The operator can also set the Eco Preview mode to remain active, whereby the operator can manually exit.
Note: To display the Eco Preview button, a TVU transmitter must be selected from the source menu.
To set up the Economy Preview Timer feature, complete the following steps:
- In the server information pane, click the Eco Preview button.

Appendix A – Network and firewall configuration
This section provides related support documentation for network and firewall configuration.
TVU Networks® recommends that you assign a static IP address to the TVU server to ensure the network configuration remains stable.
Contact TVU Networks support if you want to use a configuration other than the one specified in the this user guide.
The following configuration allows the transmitters and servers to link with each other and permit video transport automatically.
Complete the following steps to configure your TVU Pack router or firewall:
- Allow TCP Outgoing traffic from the TVU server on port 3970.
- Allow UDP Outgoing traffic from the TVU server on port 123.
- Permit all TCP/UDP incoming traffic for port 8088 to the server.
- Forward all traffic arriving on port 8088 of the external firewall interface of the IP address of the TVU server.
Recommended firewall configuration for remote control of the server from an iPad or smartphone
The TVU Pack hotspot feature allows remote configuration of the TVU Pack server settings from a smartphone. To enable this feature, permit all TCP incoming traffic for port 8288 to the receiving terminal; forward all traffic arriving on port 8288 of the external firewall interface to the IP address of the TVU Receiver. This port is configurable.
Bandwidth requirements
TVU Networks recommends a stable, low latency connection with guaranteed bandwidth for best results. Allowances should be made for bandwidth of incoming TVU transmitter transmissions based upon the following criteria:
- Each TVU server can utilize up to 20 Mbps of downstream bandwidth per live video feed.
- A minimum of 20 Mbps upstream bandwidth per TVU server is required for all features to function efficiently.
TVU server port-forwarding guidelines
TVU has developed a separate internal document for port-forwarding information. Please refer to the latest “TVU Server Port-Forwarding Guidelines” for Models VS3100, VS3200, VS3250, VS3500, VS3550, VS3600, and VS3650. If you are a customer, contact TVU Support for detailed information.
