1) Streaming
Mode
: Streaming can be set for either USB 2.0 streaming (MJPEG) or IP streaming (H.264); but not both at
the same time. The QC-USB can stream USB and accept IP control, or it can IP stream with IP control. Choose the
streaming mode here.
2) USB Device Name:
Allows the user to use a “friendly name” per system. In a BYOD format, the user has the ability to
move between different UC conference rooms and have the ability to assign the PC’s USB resources to that room.
3) Color
Space
: The UVC drivers will negotiate the color depth, but this parameter allows the user to reduce the color depth
to 4:2:0, which is used with the older/cheaper webcams and applications, where image quality is not as critical. The 4:2:2
color is used by many applications that take advantage of the performance of the camera where the colors are more
vibrant and precise.
4) IP Streaming Settings:
The Video Settings allow the selection of the target performance for the IP Streaming. The QC-
USB is set up for a variable bit rate and the user can select the video resolution and the quality, such as High Quality
(Best), Standard Quality (Better) and Low Bandwidth (Good). Every effort to eliminate stupefyingly bad combinations with
the 5 or 6 parameters that make up the image size, quality, bit rate, bandwidth etc… has been made, so you can’t pick
1080p at a bit rate of 128Kbps, which would look totally wicked awful - and probably wouldn’t work anyway.
5) Streaming Protocol and URL
: Admin chooses the streaming type and the port number for RTSP. The HLS port is
always on 80. The supported protocols are RTSP and HLS (Apple’s HTTP Live Streaming). RTSP is best for live
applications, where HLS serves the Apple iOS devices and is better for playback due to the amount of buffering the HLS
has built-in. The Streaming URL auto populates and that path can be changed.
When finished setting up the streaming parameters click Save to put the changes into effect or cancel, which will not save
the configuration.
