The VPLE user interface is divided into two modes: Presentation Mode and
Dataset Mode. The following two annotated screenshots identify the components
that make up each mode. The rest of this document will refer to these
Toggle button located in the Tool Bar for switching between Presentation Mode
and Dataset Mode. The highlighted toggle button signifies the currently
selected Mode. From Presentation Mode, double-clicking a dataset from the
Presentation Playlist View will open that dataset in Dataset Mode.
Add Dataset from File opens a file browser into the
media directory and gives users the option to navigate to and add a dataset to
the Presentation Playlist View that is not available in the SOS Data Catalog
database (and is therefore not showing up in the Search Results View).
A list of all the datasets that have been added to the presentation playlist
you are currently creating. Double-clicking on a dataset will open the dataset
in Dataset Mode so it can be previewed or modified. The number in parentheses
is the number of datasets in the presentation playlist.
Add or view presenter notes to/for the currently open presentation playlist,
or, view the dataset info for the currently selected dataset. The toggle
button at the top allows users to indicate whether they want to view Presenter
Notes or Dataset Info.
View an existing presentation playlist. Click and drag a dataset from this
view to add it to the Presentation Playlist View. The number in parentheses is
the number of datasets in the reference presentation playlist.
The Search Panel allows you to quickly search and browse for datasets in the
entire SOS Data Catalog (all of the NOAA-managed datasets) and the Site-Custom
datasets on your SOS computer. (Site-Custom datasets have a diamond icon at
the end of their name so that they are easy to identify at a glance.) Simply
click on any combination of filters (Major/Sub Categories, Movies/Realtime,
etc.) to narrow down search results. The dataset search results will appear in
the Search Results View. The toggle button at the top allows users to indicate
whether they would like to search within Datasets or Live Programs.
You can also search for datasets by typing a search term in the search text
field. By default, the search field searches through dataset titles, keywords,
and dataset contact name/organization.
Pressing the Clear Search Filters button clears all
filters and search terms and shows all datasets available on your SOS computer
in the Search Results View.
If the Live Programs toggle has been selected, the
search filters are disabled and only browsing by Major Category and Live
Program name is supported. Also, for Live Programs, a small
i button appears next to the Add Dataset from File
button. This button is a toggle between:
Live Program Presenter Notes and My Presentation Playlist Presenter Notes
when the Presenter Notes toggle is selected in the Search Panel
Live Program information and information for the currently selected dataset
when the Dataset Info toggle is selected in the Search Panel
The Search Panel checkboxes are tri-state filters. This means that each
checkbox supports three modes: Unchecked, Checked, and Intermediate. For
example, for the Has Audio checkbox:
Unchecked and filled is the default state, and the search will return
datasets with or without audio
Checked and filled will return datasets that do have audio
Unchecked and not filled will return datasets that do not have audio
A list of all the datasets that match the filters selected in the Search Panel.
Click and drag a dataset from this view to add it to the Presentation Playlist
View. The number in parentheses is the number of datasets found.
A component of a dataset. For Base Layer, Layer, and PIP, the underlying data
can be an image file, a movie, or a directory of images. An SOS dataset can
have multiple Layers and PIPs. There are 6 main element types in SOS:
An industry standard SubRip Subtitle file (.srt) that contains a sequential set
of closed captions/subtitles with their start and end timecodes and that runs
in sync with global data that is either a movie or a directory of images.
View and modify the global attributes of a dataset (ex. name, sphere tilt,
frames per second, etc.) and the attributes of Elements of a dataset such as a
PIP’s width, height, and location. Every attribute in each of the tabs
corresponds to an attribute/value pair that gets written to a dataset’s
playlist.sos file. Please see the Playlist Reference Guide
detailed information about each attribute.
The Tab View also includes a Description tab for the dataset. For NOAA-managed
datasets, the description comes from the SOS Data Catalog. For Site-Custom
datasets, the description comes from the description that your site entered for
A list of all the Elements in the dataset shown as a set of track lanes.
Clicking on a track lane will highlight the corresponding Element in the
Preview and will show the Element’s attributes in the Element Tab View. Each
track lane contains 4 buttons:
Reorder an Element. Note that re-ordering is only relative to an Element type
(for example, a Layer Element will only get re-ordered relative to other
Layers). If the Element has a Lock icon, it cannot be re-ordered.
