5 Audio/Video (AV) Functions
Onsight can provide a complete record of a call, including two-way voice, video, subject audio, images and
telestration. Calls can also be recorded without an active video stream.
Once a call is connected, the Onsight device can send an AV media stream to Onsight Expert.
In a conference call the AV media stream is seen by all Onsight Expert participants. The secondary Onsight
devices can participate in image sharing and streaming of recorded audio/video, but unlike the primary Onsight
device, can not participate in live streaming.
5.1 Turning the Video Stream On or Off
Enabling the video stream sends a subject audio/video media stream from the Onsight device to the Onsight
Expert participants. The stream will continue as long as the call is connected or until the operator or Onsight
Expert selects an option to stop or temporarily freeze the streaming.
Î To start and stop streaming live video to Onsight Expert:
1. Press the Stream button on the top of the Onsight device.
2. 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.
Î To temporarily freeze the streaming video, without exiting from the video stream:
1. Press the Enter button
. This freezes the video image.
2. Press the Enter button again to restart live video.
3. The message “Video resumed” appears.
If the device is sharing an image when the stream is resumed, then the video
stream resumes on the Onsight Expert Call window, but the captured image
remains in the Onsight device’s Viewfinder until image sharing is ended by
either briefly pressing the Capture button, or selecting End Still Image
Sharing from the Image Shared icon
.
5.2 Setting the Subject Audio Source and Volumes
The Onsight device provides two audio channels: one for Subject Audio and one for VoIP telephone
communication.
Subject Audio is the unprocessed sound coming from the subject. The sound (Subject Audio) being captured and
streamed with the video is captured by the Onsight device’s built-in microphone or from an external audio source
connected to the Onsight device’s Audio Line-in port. This allows the Onsight device to capture and stream audio
that is time-synchronized with the video.
The Audio Line-in port is standard for the Onsight 1000 (see paragraph 1.6.1 on page 3). For the Onsight
2000/2
500, Audio Line-in is located on the I/O Sled accessory (see paragraph 1.7.3 on page 10).
For the Onsight 2000/2500 device, the Audio Line-in port can be configured to
accept either an external microphone or line-level audio input.
The Stream button also starts and stops streaming of Subject Audio, just as in video streaming described in
paragraph 5.1.
For VoIP telephon
e communication see paragraph 3.5, VoIP Telephone Communication, on page 29.
