The monitor output display is made up of 8 panels. Below is a description of each panel and the information it displays.
Input View
The main panel displays your current video input from the connected SDI video source.
On Air Status
Prior to streaming, the on air status indicator will display ‘off’ to let you know
Web Presenter HD is standing by and ready to broadcast. When streaming begins, the indicator will display a bright red ‘on air’ status until streaming is stopped.
Underneath the on air indicator is the duration counter. When you press the on air button on the Web Presenter HD, the duration counter will start running.
If your Web Presenter HD is off air but will stream via a tethered smartphone, the ‘off’ indicator includes a blue smartphone icon in the corner. When on air, the smartphone icon will illuminate red.
Live Stream
The live stream panel displays information about your live stream settings. This includes the streaming platform, server and the first 10 digits of your streaming key. It also displays the stream resolution and quality settings.
Using the Monitor Output |

Video Input
The 5 mini viewers at the top of the video input panel show the previous 6 seconds of your live stream, each mini viewer represents 1.2 seconds of streaming time.
Below the mini viewers you can view detailed technical information about the video input source connected to your Web Presenter HD’s SDI input.
Input Standard |
Displays the resolution and frame rate of the SDI video input. |
|
Web Presenter HD supports up to 2160p60. |
Colorimetry |
Shows the color space of the SDI video input. Web Presenter HD |
|
supports Rec.601, Rec.709 and Rec.2020 color spaces. |
SDI Ancillary Data |
Ancillary data is data carried in the SDI video input that is in |
|
addition to video. This includes embedded audio, timecode and |
|
closed captions. If your SDI input includes ancillary data then |
|
‘Present’ will be displayed. |
|
|
Timecode
Closed Captions
SMPTE 292 CRC
Luminance Y Bits
and Chroma Bits
Displays the timecode from the SDI video input source.
If your SDI video input includes Closed Captions the format will be displayed here. CEA-608 and CEA-708 formats are supported.
This is an error checking function for SDI video. If your
Web Presenter HD detects a problem in the SDI video input it will display an error. CRC errors are usually caused by a faulty SDI cable or a cable that is too long.
The indicators for ‘luminance y bits’ and ‘chroma bits’ show you the activity of the SDI video input signal. Each letter represents the state of one bit of the video signal.
X - An ‘X’ indicates a constantly changing bit. L - A low bit.
H - A high bit.
SDI offsets are subtracted to make it easy to understand. For example, all bits are low when video is black.
Generally, all 10 bits for your SDI video input will show ‘X’ to mean all the bits on your video stream are changing constantly. If your SDI input is 8 bit video, the two rightmost bits will always be ‘L’ as they don’t have any data. If a bit stays ‘L’ or ‘H’ when you expect it to be ‘X’, this indicates a ‘stuck bit’ and could be the result of a fault in the upstream video.

Audio Input
The audio waveform display at the top of the audio input panel shows the audio information for the past 6 seconds of your live stream. This is continually updated and scrolls from right to left.
Below the audio waveform display you can view detailed technical information about the audio input.
Sample Frequency
Emphasis
Audio Source Lock
Word Length
Origin
Time of Day
Audio Bits
Displays the sample frequency rate of the audio embedded in the SDI input.
Indicates if your audio source has its emphasis option enabled.
Indicates whether the audio source frequency is locked to an external reference source.
Shows the bit depth of the audio embedded in the SDI input.
These four characters indicate the channel origin.
Free run timecode.
Similar to ‘luminance y bits’ and ‘chroma bits’. An ‘X’ means a constantly changing bit. If a ‘L’ or ‘H’ is displayed this indicates a ‘stuck bit’ and may mean the the audio signal bit depth is less than expected.
VUCP
Sample Address
AUX Bits Use
Audio Channels 1-32
Reading VUCP bits from left to right: the ‘V’ bit indicates ‘valid’, ‘U’ is the ‘user’ bit, ‘C’ is the ‘checksum’ bit, and ‘P’ is for ‘parity’. This field is like ‘audio bits’.
Audio sample counter.
Indicates whether AUX bits are used for main audio.
Each digit represents an embedded audio channel on the SDI input. A ‘P’ shows that an audio channel is in use and a ‘-’ means that there is no audio on that channel.
