Data transmission panel – Live, record, and Transcriber mode tabs

The data transmission panel’s Live, Record, and Transcriber tabs control different modes of operation:

(1) Live mode: The Live mode is the primary interface used during a Live transmission. When the Live tab is selected, the Bitrate, Delay, and Operational Mode buttons display. In addition, the status of each of the data card network connections is displayed in the data card panel.

Record mode operations

The Record tab displays recorded content timelines and file management operations.

Record mode

Whenever a video source is connected, the TVU transmitter automatically creates a new recording on its internal SSD in a FIFO loop. Each recorded clip is displayed in the Recorded content timeline in the Record tab.

This recording utilizes two separate encoders that are used for the Live transmission. This ensures that a high-quality version of the content (whether Live or not Live) is available.

Recorded content panel

The recorded content panel has the following controls and functions:

(1) Recorded content timeline: The timeline displays clips initiated by date.

(2) Number of clips indicator: The green-circled numbers next to the date indicate the number of clips available. Refer to the recorded content timeline as shown below.

(3) Clip thumbnails: Thumbnails of selected clips are displayed below the recorded timeline. The start time for the clip also displays below the thumbnail. The currently selected clip is outlined in blue.

(4) Clip duration: When you highlight a thumbnail, its start and end times appear in the left column below the “Download All” button.

(5) Clip extraction timeline: A thumbnail of an extracted clip displays and can be edited in the clip extraction timeline.

(6) Clip scrub bar: Thumbnails by frame of a selected clip can be marked by sliding the white beginning and ending markers on the green clip scrub bar.

After a clip is scrubbed, the user can preview the clip by pressing the Preview button, which initiates a live transmission of the clip.

Click the Download button to transfer the clip to the File Management panel. The download status displays in the Download tab records list during the download.

File Management panel

The File Management panel has the following controls and functions:

Note: A file may be played before the transfer operation completes.

(3) FTP tab: The FTP tab displays files uploaded from an FTP client. The stored data can be played or deleted after a clip status displays 100% uploaded.
