The optional TVU dual-encoder feature records a pristine, high-resolution copy of all detected video directly to the local SSD storage. SSD storage ensures that no video is lost, even if the original transmission encountered difficulties.

The TVU One transmitter continuously records at a high bitrate using a second encoder. The second encoder is always on when the unit is powered and does not require any manual configuration or power.

An operator can then view and extract recorded content from the TVU transmitter remotely using the receiver download feature. In addition, the local TVU operator can access the recorded content for editing purposes.

Autosync feature

Autosync is a high-speed file transfer feature that automatically pushes the files from the transmitter to the receiver using IS+.

There are two Autosync methods you can use to send files to the TVU receiver automatically:

• You can perform Autosync by inserting a USB stick into the transmitter USB connector.
• You can use the TVU transmitter wireless hotspot feature to transfer files directly to the TVU transmitter for upload.

Using the Autosync feature with a hotspot (PC)

Complete the following steps to perform an Autosync file transfer using a wireless hotspot:

1. Search for the hotspot on your laptop or smartphone. The SSID is:

TVUPACK_XXXX
(Where X is the last 4 digits of the TVU transmitter PID)

2. Connect to the SSID.
3. The password is the last 8 digits of the PID of the backpack (Note: All characters are uppercase).
4. Once the connection is established, obtain the IP address in the Connection details.
5. Open file explorer, select “Network,” and enter the IP address. For example: //192.168.3.1
6. The Autosync folder displays as shown below in “Network IP connection and Autosync folder.” Drag-and-drop the files to be transferred into the Autosync folder.

Using the Autosync feature with a hotspot (Mac)

Complete the following steps to perform an Autosync file transfer using a wireless hotspot:

1. Search for the hotspot on your laptop or smartphone. The SSID is:

TVUPACK_XXXX
(Where X is the last four digits of the TVU transmitter PID)

2. Connect to the SSID.
3. The password is the last eight digits of the PID of the backpack (Note: All characters are uppercase)
4. Go to Finder and click the Go tab. Then, select Connect to Server.

5. Enter “192.168.3.1” in the “Server Address” field and click the Connect button.

6. A “Connect As” pop-up menu displays. Click the Guest radio button and then the Connect button.

7. Move files you want to send using TVU Autosync to your desktop’s “Autosync” shared drive icon.

Using the Autosync feature with a USB stick

The Autosync feature allows you to transmit wireless digital content from the TVU transmitter to the TVU receiver using a USB memory stick.

The TVU transmitter will auto-detect the memory stick and automatically transfer the contents to its internal SSD hard drive. The content will then be available for wireless transmission to the TVU receiver.

Attention: The supported disk format is FAT 32 only.

To perform an Autosync using a USB memory stick to a TVU One transmitter, complete the following steps:

1. Create a directory named “autosyncimport” in the memory stick.
2. Copy the content you want transferred into the “autosyncimport” directory.
3. Plug the memory stick into any spare USB port on the transmitter.
4. Monitor the file upload status on the TVU transmitter’s LCD screen. Do not unplug the USB memory stick during the file upload, as this may cause the system to malfunction.

Accessing stored content

You can download the recorded content locally to a USB Memory Stick.

Connecting a USB memory stick (FAT 32 only) to a TVU transmitter while the video source is disconnected, the entire video content of the last session is transferred to the memory stick in an NLE-compatible format.

Additionally, the Recording screen will list the recorded sessions on the TVU transmitter SSD available for download on the web-based monitoring and controls interface. The following three functions are available on the Recording screen:

• Copy and Play
• Upload
• Mark in and Mark out

Refer to “Working with recorded content” for instructions about using the Mark in and Mark out functions.

Copy and Play functions

The Copy function allows the user to extract recorded clips listed in the recording screen from the transmitter to a local USB drive. To use the Copy function, complete the following steps:

1. Click the drop-down menu and select Recording.
2. Select the checkbox next to the desired recording(s).
3. Click the Copy button. A warning message displays if there is not enough space on the memory stick to complete the copy function.
4. Select a clip and click the Play button to preview any recorded content.

Note: Playback is only available on iOS devices.

Once a file has been selected to download to the USB, a “Copying” message will appear when the process has begun, and a “Complete” message will display when the process is complete.

Note: The TVU transmitter cannot be “live” to use this function.

Upload function

The Upload function in the Recording screen will use the Autosync feature to push recorded clips from the transmitter to a remote receiver.

Working with recorded content

The Recording panel features three functions that allow you to work with recorded content.

Mark in and Mark Out functions

The Recording panel’s Mark in and Mark Out functions allow users to explicitly select a portion of a live ingest for extract or upload functions. For example, this function allows users to isolate and copy a live video clip to a USB thumb drive or upload it directly to a receiver using the Recording status panel.

To use the Mark in and Mark Out functions, complete the following steps:

Note: The TVU device is always recording when it is powered on and a valid video source is connected.

1. Click the drop-down menu and select Recording.

2. Click the Mark in button to mark the IN point of a segment in the recorded video in the TVU Pack Recording panel.
3. Click the Mark Out button to mark the OUT point of a segment in the recorded video on the TVU Pack.

Note: After the IN and OUT points are identified, it is possible to play the clip, copy it locally to an inserted USB thumb drive, or upload it directly to the selected receiver.

4. In the Name field, enter a specific name for the recorded segment.
5. Click the Apply button to add the recording to the recorded segment list at the bottom of the Recording status window.
6. To search for and display a recorded video segment by date, click the calendar icon in the Query search field, select the recording date, and click the Query button to display the recording in the list. Click the Select All checkbox to display only recordings completed on a selected date.
7. To select and play a preview of a specific video recording in the list, click the checkbox next to the recording and click the Play button.
8. To copy a clip from the list to a TVU Pack, insert the thumb drive into the TVU Pack USB port, click the recorded file checkbox in the list, and click the Copy button.
9. Click the Upload button to transfer the copied recorded file from the TVU Pack to the default receiver (designated in the receiver window).

Upload feature

The TVU MLink Upload window allows users to upload files using the Autosync feature to a specific receiver.

To select a specific receiver to upload files from, complete the following steps:

1. Click the drop-down menu and select Upload.
2. Select the specific receiver from the drop-down menu for each file you want to upload.
3. After selecting a receiver, click the Select Default R: checkbox to make your selection the default receiver. This will enable all future files to be uploaded to the default receiver.
4. Click Apply to save your changes.
