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.
9Using 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.
10Using 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
suppor ts 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.
11Using 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 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 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’.
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.
12Using 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.
13Using 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 unit’s front panel.
14Using Web Presenter Setup

Live Stream Tab

Video Output
Stream Standard
Click on the ‘stream standard’ menu to select the video resolution setting for your stream. Youcan choose from 720p25 up to 1080p60.
Settings
If you have custom streaming settings, for example an XML file from a Blackmagic ATEM Streaming Bridge, you can import them by clicking the ‘load streaming settings’ button.
For more information on creating custom settings and connecting to ATEM Streaming Bridge, refer to the ‘Creating Video Links with ATEM Streaming Bridge’ section later in this manual.
Live Stream
Platform
Click the ‘Platform’ menu to select the streaming platform for your broadcast. Options include YouTube, Facebook and Twitch. If you have imported custom streaming settings they will also appear in the platform list.
Server
Select the server that is closest to your location by selecting it from the list. The server list will vary depending on your chosen streaming platform.
Key
Enter the streaming key that has been assigned to your broadcast from the streaming platform. For more information on obtaining a streaming key, see the ‘Getting a StreamKey’ section.
Quality
Select the streaming quality:
• HyperDeck High 45 to 70 Mb/s
• HyperDeck Medium 25 to 45 Mb/s
• 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. It’s best to check with your network administrator if they are managing your computers and network in your company.
Setting Internet Sharing forDirectStreaming
If you are unable to plug Web Presenter HD directly into a network switch or internet router, youcan share your computer’s internet connection with Web Presenter HD through its Ethernet port.

Developer Information

Blackmagic Web Presenter Ethernet Protocol

v1.0
Overview
The Blackmagic Web Presenter Ethernet Protocol is a line-oriented, text-based protocol to control a Web Presenter. The Blackmagic Web Presenter Ethernet Protocol is available for Blackmagic Web Presenter HD. Lines from the Web Presenter server will be separated by an ASCII LF sequence. Messages from the user may be separated by LF or CR LF.
Connection
The Web Presenter server is accessed by connecting to TCP port 9977 on a Web Presenter.
Connection Response
Upon connection, the Web Presenter server sends a dump of the device’s state. The Web Presenter server sends information in blocks, with each having an identifying header followed by a colon. A block spans multiple lines and is terminated by a blank line. Each line in the protocol is terminated by a newline character.
Following the header, a block contains either a single multi-line string or a sequence of key/ value pairs arranged one per line. The f irst colon on a line is used to delimit the key and the value. A value may be a comma separated list. In this case, values in the list must have the “,” and “\” characters escaped with a “\” character.
To be resilient to future protocol changes, clients should ignore blocks they do not recognize, up to the trailing blank line. Within recognized blocks, clients should ignore keys they do not recognize.
The protocol preamble block is always the f irst block sent by the Web Presenter server:
PROTOCOL PREA MBLE:
Legend
End of line
↵
... and so on
Orange Text Client Generated
Grey Text Server Generated
Ve rs i o n: 1.0
↵
The version field indicates the protocol version. When the protocol is changed in a compatible way, the minor version number will be updated. If incompatible changes are made, the major version number will be updated.
The initial status dump is concluded by the end prelude block:
END PRELUDE:
↵
↵
↵
↵
23Developer Information
Status Updates
When any device parameter is changed on the Web Presenter server by any client, such as the Blackmagic Web Presenter Setup utility, the Web Presenter server resends the applicable status block, containing only the items that have changed. Status updates can also occur due to external changes such as tethering to a smartphone or when a streaming service is disconnected.
For example. if the input video mode is set to Auto, the following block will be sent:
ST REA M SE T TI N G S:
Video Mode: Auto
↵
↵
↵
Requesting Changes
To change one or more parameters in a block, the client should send the appropriate block header in the same form the Web Presenter server sends, followed by the key/value pairs to be changed. For example, to change the input video format to 1080p59.94, the user should send the following block:
ST REA M SE T TI N G S:
Video Mode: 1080p59.94
↵
The block must be terminated by a blank line. On receipt of a blank line, the Web Presenter server will either acknowledge the request by responding:
ACK
↵
↵
or if unable to parse the block responding with:
NACK
↵
↵
↵
↵
After a positive response, the client should expect to see a status update from the Web Presenter server showing the status change. This is likely to be the same as the command that was sent, sometimes followed by other blocks providing data specific to the change.
ST REA M SE T TI N G S:
Video Mode: 1080p59.94
↵
↵
↵
If the Web Presenter server does not understand a key in the requested block, the key will be ignored. If an invalid value is provided for a known key, then the request is ignored and the Web Presenter will respond with the existing value for the key. In both cases the Web Presenter server will still respond with an ACK.
ST REA M SE T TI N G S:
Video Mode: UnsupportedMode

Blackmagic Embedded Tally Control Protocol
Version 1.0 (30/04/14)
This section is for third party developers or users who may wish to add support for the Blackmagic Embedded Tally Control Protocol to their products or system. It describes the protocol for sending tally information embedded in the non active picture region of a digital video stream.
Data Flow
A master device such as a broadcast switcher embeds tally information into its program feed which is broadcast to a number of slave devices such as cameras or camera controllers. The output from the slave devices is typically fed back to the master device, but may also be sent to a video monitor.
The primary flow of tally information is from the master device to the slaves. Each slave device may use its device id to extract and display the relevant tally information.
Slave devices pass through the tally packet on their output and update the monitor tally status, so that monitor devices connected to that individual output may display tally status without knowledge of the device id they are monitoring.
Assumptions
Any data alignment / padding is explicit in the protocol. Bit fields are packed from LSB first.
Blanking Encoding
One tally control packet may be sent per video frame. Packets are encoded as a SMPTE 291M packet with DID/SDID x51/x52 in the active region of VANC line 15. A tally control packet may contain up to 256 bytes of tally information.
Packet Format
Each tally status consists of 4 bits of information:
uint4
bit 0: program tally status (0=off, 1=on)
bit 1: preview tally status (0=off, 1=on)
bit 2-3: reserved (0x0)
The first byte of the tally packet contains the monitor device tally status and a version number.
Subsequent bytes of the tally packet contain tally status for pairs of slave devices. The masterdevice sends tally status for the number of devices configured/supported, up to a maximum of 510.
