Audio/Video (AV) Functions
Once a call is connected, the MCD can send an AV media stream to the
MCA software client.
5.1.
Turning the Video Stream On or Off
To start streaming real-time video to the MCA software client, press the
green
Stream
button on the top of the MCD. Press the
Stream
button
again to stop streaming. This does not disconnect the call; the stream can
be started and stopped as often as desired within the current call.
This sends a live audio/video media stream from the MCD to the MCA
software client. The stream will continue as long as the call is connected
(i.e., neither user hangs up the call), or until the Operator or MCA user
selects an option to stop streaming.
5.2.
Setting the Subject Audio Source
The MCD provides two audio channels: one for subject audio and one for
VoIP telephone communication (see page 13).
The Subject audio — the audio being captured and streamed with the
video — can be captured by the MCD’s built-in microphone or from an
audio source connected to the Audio-In port.
Note:
Audio-in, S-video, Ethernet and USB are only available on the Sled
accessory. For more information on using the Sled, see
Accessories
on
page 14.
The Audio-in port can be configured as either microphone or Line-in. This
allows the MCD to capture and stream high-quality audio that is time-
synchronized with the video. The green
Stream
button also starts and
stops streaming of Subject Audio, just as in video streaming described
above.
To set which source will act as the Subject Audio Source:
1.
From the standard Viewfinder display window, press the
Display
button three times (or until the Main Menu appears).
2.
Tap the
Configuration
option with the stylus to display the
Configuration screen.
3.
Display the
Audio
tab. This tab allows you to control speaker and
microphone volume, and to select the Subject Audio Source.
5.3.
Using S-video
Note:
Audio-in, S-video, Ethernet and USB are only available on the Sled
accessory. For more information on using the Sled, see
Accessories
on
page 14.
When using an MCD model which has S-video input/output, the S-video
source must be attached to the MCD and powered before setting the video
source to
S-video
in the
Configuration Video
tab. Otherwise, the video
stream being sent to the MCA may not synchronize and may not be
aligned to the frame. If synchronization does not occur, correct it by
setting the MCD’s video source to
Internal
and then back to
S-video
. See
Configuration
on page 30 for more information about configuring the MCD
video.
