Using the Monitor Output
The monitor output lets you monitor the video input, audio levels, on air status, data rate and
cache levels, plus technical information about the SDI input.
The monitor out on Web Presenter HD provides comprehensive
information including data rate and cache status.
10Using the Monitor Output
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.
11Using 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 Displays the timecode from the SDI video input source.
Closed Captions If your SDI video input includes Closed Captions the format will be
displayed here. CEA-608 and CEA-708 formats are supported.
SMPTE 292 CRC 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.
Luminance Y Bits
and Chroma Bits
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.
12Using the Monitor Output
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 Displays the sample frequency rate of the audio embedded
in the SDI input.
Emphasis Indicates if your audio source has its emphasis option enabled.
Audio Source Lock Indicates whether the audio source frequency is locked to an
external reference source.
Word Length Shows the bit depth of the audio embedded in the SDI input.
Origin These four characters indicate the channel origin.
Time of Day Free run timecode.
Audio Bits Shows the bit activity in the audio samples embedded in the
SDI connection. Even if the audio channel status says you have
16, 20 or 24 bit audio, the audio bit activity will confirm it.
VUCP Reading VUCP bits from left to right: the ‘V’ bit indicates ‘valid’,
‘U’is the ‘user’ bit, ‘C’ is the ‘channel status’ bit, and ‘P’ is for
‘parity. This field is like ‘audio bits’.
Sample Address Audio sample counter.
AUX Bits Use Indicates whether AUX bits are used for main audio.
Audio Channels 1-32 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.
13Using the Monitor Output
Data Rate Display
The data rate display shows the current data rate of of the encoder over the past
60 seconds. The data rate is measured in megabits per second. This indicator runs
consistently, even when off air, so you can accurately gauge your bandwidth before
going on air.
Cache Display
The cache display shows the percentage of Web Presenter HD’s built in memory buffer
that is currently in use and the graph shows the amount used over the past 60 seconds.
The cache is a small amount of internal memory that continuously records and plays the
program output. It acts as a safety measure if the streaming data rate decreases below
a level able to sustain video.
The variable nature of the internet is mostly due to network activity or wireless signal
strength, so if the broadcast data rate decreases, the buffer data will increase
accordingly. If the connection speed becomes slow enough that it cannot support the
video stream, the cache will fill with video frames to compensate. However, once the
cache is 100% full, the video stream will be compromised, so you will want to avoid a
full cache where possible. You can run a test by connecting a video feed and watching
the cache display in the monitor output without having to start the stream. If the cache
frequently approaches 100%, choose a lower quality in the live stream settings.
Audio Meters
You can monitor the levels of your audio source using the audio meters. These can be
set to display either PPM or VU levels in the Web Presenter HD’s menu settings. If your
audio levels are too high the meters will illuminate red and may mean that the audio in
your live stream could become distorted or clipped. Ideally try to keep your audio
towards the top of the green section and occasionally in to the yellow section.
14Using the Monitor Output
Using Web Presenter Setup
When your Blackmagic Web Presenter is connected to a network, any computer connected to
the same network can be used to control your Web Presenter remotely. With Blackmagic Web
Presenter Setup, you can access the same controls and settings that are available on the units
front panel.

HyperDeck Low 12 to 20 Mb/s
Streaming High 6 to 9 Mb/s
Streaming Medium 4.5 to 7 Mb/s
Streaming Low 3 to 4.5 Mb/s
The data rate used by the quality setting will change depending on the video standard
Web Presenter HD is using. For example, if you select ‘streaming high’ quality and are
running at 1080p24 then it would use the 6 Mb/s data rate.
The data rates used on HyperDeck High are 45 to 70 Mb/s, the rates for HyperDeck
Medium are 25 to 45 Mb/s and the data rates used for HyperDeck Low are 12 to 20
Mb/s. The streaming data rates are lower to allow for transmitting the data over the
internet, so the data rate for Streaming High is 6 to 9 Mb/s, the data rate for Streaming
Medium is 4.5 to 7 Mb/s and the data rate for Streaming Low is 3 to 4.5 Mb/s.
You will notice that each setting has 2 data rates mentioned. The lower number is used
for the lower frame rates of 24p, 25p and 30p, while the higher data rates are used
when you are running higher frame rates of 50p and 60p. It’s also worth noting that the
default setting for the streaming quality is Streaming High 6 to 9 Mb/s, as this gives a
very high quality streaming channel.

Network Settings
Your Web Presenter HD can connect to the network using a static IP address or by using DHCP.
DHCP - will automatically set an IP address for your unit and connect it to your network without
any settings changed.
The dynamic host configuration protocol, or DHCP, is a service on network servers and routers
that automatically finds your Web Presenter HD and assigns an IP address. DHCP makes it easy
to connect equipment via Ethernet and make sure that IP addresses do not conflict with each
other. Most computers and network switches support DHCP.
Static IP - If you want to set the IP address yourself, simply set the protocol setting to ‘static IP
and change the IP settings manually.
A static IP address is one that won’t change even if your Web Presenter HD is rebooted.
Using a static IP address might be necessary if your connecting your Web Presenter HD to a
corporate network. If you have a network administrator, it’s possible your network might have
custom IP addresses for all the equipment connected to it. Its best to check with your network
administrator if they are managing your computers and network in your company.
