About the Polycom Recording Studio Software
The Polycom PRS 2000 Software is Polycom's presentation capture software
which runs on the Polycom PRS 2000 appliance. The Polycom PRS 2000
Software consists of two interfaces; the Operator Interface and the Touch
Interface.
The Operator Interface, covered in this chapter, is used to create mixes for
different output experiences and to define presets that will be used for
recording a presentation. Different configurations can be saved for each
individual presenter or situation.
The Touch Interface, covered in the next chapter, is a simplified interface
designed for the presenter. It provides all the functionality required for a
presenter to create a recording and to switch among various views using the
presets created within the Operator Interface.

Using the Session Properties Polycom Recording Studio Software
Windows Media
The Windows Media output type creates a recording viewable in any player
or device that supports Windows Media Video (.wmv) files. This includes
playback in Windows Media Player, a Windows Media Player embedded in a
web page, or Windows Mobile devices.
The Distribution section of the Windows Media output type configuration
allows users to dictate whether they want .wmv files archived and whether
they wish to enable Pull or Push broadcasting to or from the Windows Media
Server. Pull broadcasting requires that you provide your HTTP port. Any
computer with access to that port can then access the content. Push requires a
URL and template URL, as well as authorized user credentials for access.
Polycom, Inc. 11
Polycom PRS 2000 Administrator Guide Using the Session Properties
Raw
The Raw output type is for archive-quality video. Raw files are uncompressed
and are larger in file size, but are uncompromised in quality.
MP3
The MP3 output type is an audio-only output type for playback on any device
that supports MP3s. This output type is ideal for podcasting a recording.

Note about Session Configuration Files
Users of the Polycom PRS 2000 appliance have the ability to create multiple
session configuration files. A session consists of the following high level
categories, Metadata, Inputs, Outputs, Presets and Video Mix.
Within the metadata category, the user has the ability to assign a title, author,
subject, etc. A user could select multiple session configurations with metadata
to correspond to different lecturers for their specific presentations. However,
a user of the system can modify the title, author, etc. with the same session
configuration.
Within the Input category, the user can select the specific video, VGA and
audio sources to have active for a given presentation/recording. The first is
where the Polycom PRS 2000 appliance is used as a mobile recording system
for different studios or rooms throughout an organization. In this use case,
different A/V equipment, cables, and VGA sources are typically deployed in
each room. By using different session configuration files which correspond to
the particular rooms, users can easily map the different audio video layouts to
simplify mobility.
For the Output category, the user can use session configuration files in a
multitude of ways. First, a user can specify different encoder outputs, which
not only include standard settings such as resolution and frame rate, but also
feature audio and video mixes. For example, the H.264 encode could be a mix
which features a full screen of Video Input 1 and Microphone 1, whereas the
Windows Media mix includes 3 video inputs and VGA as well as an audio mix
of 3 different audio inputs. The audio outputs could also be extended to
support multiple language inputs. Countless permutations exist of different
mixes that can be created using the Polycom PRS 2000 appliance.
Polycom, Inc. 25
Polycom PRS 2000 Administrator Guide Capturing Your Experience
Presets were discussed in an earlier section. It should be noted however, that
presets map to configuration files. As such, a user can define different presets
lists for different configuration files. This capability is helpful in use cases
again where the system is mobile and different A/V equipment is available in
each room and studio.
Finally, the video mix also maintains its settings within the configuration files.
This includes saved templates, images used as backdrops, and video and
audio levels.
Events
Events can enhance a presentation with the ability to add meaningful data to
the presentation during a recording. A presenter can create a chapter point in
any part of a presentation, insert captions which will appear in the closed
captioning area of the interface, or insert search terms into any point in a
recording allowing the user to search on a keyword to locate a specific portion
of a presentation.
A Presenter can also add post-production Events to signify to the video editor,
including specific notes for the editor as well as segments of the video to be
removed via the Polycom PRS 2000 Mark In/Out feature.
The Events feature is only accessible in the Polycom PRS 2000 Operator
Interface and appears on the right window column under the Events tab.
NOTE: Polycom PRS 2000 Events are only used with the Polycom Rich Experience
player output type.

Capturing Your Experience Polycom Recording Studio Software
To add an event:
1 Under the Cue pane, click on an Event button (Chapter, Caption, Search,
URL, Mark In, Mark Out, Note, Custom).
Types of Event
2 Enter the appropriate text in the field provided. This field can be edited
3 Specify a time for the event or click the clock button (at left) to
set the current time of the recording.
4 Click on the carat button (at left) to apply it to the timeline. The
Event should appear in the Monitor pane.
5 To remove an event, click on the O button in the Monitor pane and it will
come down into the Cue pane.
6 Click the X button (at left) to cancel the Event completely.
The following list describes each of the Events that can be added during a
recording:
Chapters
Chapters can be added to specify areas in a recording a presenter may wish to
identify as a key segment in a discussion. By adding a title, a chapter is created
with the title the presenter has specified. Note that these Chapters are created
in parallel with the chapters created by the Polycom PRS 2000 OCR.
Polycom, Inc. 27
Polycom PRS 2000 Administrator Guide Capturing Your Experience
Usage example: A presenter may discuss a single image at length that
contains no recognizable text for OCR. The presenter could send Chapter
events during the discussion of that image to create chapters so the
audience can navigate to a specific portion of the discussion.
Caption
A Caption can be added to a recording by sending a Captions event. These
captions appear in the closed captioning area typically occupied with closed
captioning text that appear when the CC button in the Polycom Rich Media
Player is pushed.
Usage example: A presenter can take advantage of this feature by adding
captioning notes to display to the audience. This could be useful to display
text to highlight key concepts or to display a mathematical formula.
Search
Search terms can be added to a recording to make any segment of a
presentation searchable.
Usage example. A presenter with a speech-only discussion will not have
automatic chapter creation or searchable text. The presenter may wish to
insert searchable keywords pertaining to various segments of the
discussion so the viewer can search for that portion of the presentation.
URL
A URL event can be sent during the recording if a presenter wishes to add a
URL as a resource during a presentation.
Usage example: A presenter may have a web resource available not
available in a presentation slide. To make this URL available to the viewer,
the presenter can send a URL Event to provide a link of the online resource
to the viewer.
NOTE: To use the URL Event requires a custom script to be written to launch a
browser window.
Mark In/Mark Out
The Mark In and Mark Out events are used for post production of a recording.
Sending these events during a recording will mark the timeline with "In" and
"Out" and is viewable in Microsoft's Expression Encoder. If the presentation
requires editing, an editor can view the timeline for these "In" and "Out" marks
and remove portions of the video accordingly.
28 Polycom, Inc.
Capturing Your Experience Polycom Recording Studio Software
Usage example: A presenter can start a recording as the audience is being
seated and may only want to keep his or her speaking portions of the
recording. The presenter can then Mark In at the moment the actual
presentation is started and Mark Out during intermission or at the end of
the presentation. The presenter can Mark In and Out as many times as
needed to produce a single video without intermissions or other irrelevant
events.
NOTE: For detailed instructions on how to use the Mark In/Mark Out feature, please
see “Using the Mark in/Mark Out Feature in Expression Encoder” on page 47.
Notes
The Note event is used to provide notes for a video editor for post production
of a recording if any is required. The note will appear within Microsoft
Expression Encoder's Script Commands pane.
Presets
Usage example: The presenter can send a Note event during a recording
to flag a segment of the video to a post-production editor. This note can
specify details about a part of a recording that the presenter would like an
editor to review and edit in Expression Encoder 2.
Custom
The Custom event is a used to add a custom script into the timeline which can
be used to launch an event.
Usage example: With a Custom script event embedded into the video
timeline, a script can be written to "listen" for custom scripts to run a
command at strategic times to launch a survey window, for example.
Presets can be made from any mix you define. Multiple combinations of
elements including visual layout, audio tracks, volume levels, aspect ratio,
PTZ settings, output size and bit rate can be defined.

Silverlight Recording Layout
The Polycom PRS 2000 device has as an option two of its outputs entitled
"SLVideo" and "SLImage," both of which are used by the system to generate a
Silverlight VoD presentation package after a recording is complete.
Using the inherent capabilities of the Polycom PRS 2000 device, multiple video
and VGA inputs are detected and extracted automatically for the purpose of
rendering the Silverlight package.
Polycom, Inc. 51
Polycom PRS 2000 Administrator Guide Silverlight Recording Layout
The Expression Encoder output folder contains the Windows Media file,
HTML, corresponding snapshots to timestamps, and the XAP file. The
Silverlight VoD will also seamlessly render chapter titles from OCR (Optical
Character Recognition), thumbnails corresponding with screenshots,
metadata, and other information. See the diagram below for more
information.
NOTE: Outputs designated for Silverlight must conform to the provided naming
designation, specifically "SLVideo" for the media output and "SLImage" for image
