Screen Shot: Streaming
The Streaming Page allows an administrator to set up the type of streaming, audio delay, USB streaming settings
and USB terminal type, color space, IP streaming settings, video speed and quality, protocol and path.
The Streaming Menu:
1) The
USB STREAMING MODE is set for either USB 2.0 streaming (MJPEG/PCM) or IP streaming (H.264/AAC) however,
the AV Bridge CONFERENCE cannot stream both at the same time. It can stream USB and accept IP control, or it can IP
stream with IP control. Choose the streaming mode here. Frequently the Audio requires a delay in order for the video
and audio to arrive simultaneously. The audio delay is like the lip sync control on a BD player.
2) USB STREAMING SETTINGS allows the admin to add a device name (friendly name) and to enable HID audio controls
for applications that allow it. Here the USB Terminal Type is also set and depends upon the application and the room
audio system configuration.
Use Type 0x405 when connecting to professional audio conferencing mixers with echo
cancellation. Use Type 0x403 when connecting to audio equipment that does not have internal echo cancellation.
3) COLOR SPACE control allows the admin to reduce the color depth to 4:2:0, which is used with applications where image
quality is not as critical or the window sizes available are small. The 4:2:2 color is used by many applications that take
advantage of the video performance where the colors are more vivid and precise.
4) The IP STREAMING SETTINGS allow the selection of the target performance for the IP Streaming. AV Bridge
CONFERENCE is set up for a variable bit rate, which is much simpler to use. The user can select the resolution and the
quality, such as High Quality (Best), Standard Quality (Better) and Low Bandwidth (Good - all Good frame rates are at
15fps). Every effort to eliminate bad combinations with the 5 or 6 parameters that make up the image size, quality, rate
etc… has been made, so you can’t pick 1080p at a bit rate of 128Kbps, which would look totally gnarly-awful…if it worked
at all.
5) The IP STREAMING PROTOCOL also allows the admin to choose 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.
6) When finished setting up the streaming parameters, click on Save to put the changes into effect or Cancel to…cancel it.
