To change the settings of a station first select it on the screen (section 6).
Note: you can select multiple stations (by selecting them on the screen or clicking while holding Control key or clicking when multiselect option is enabled) and change options for all of them
Station parameters are displayed in the form on the right side of the screen (section 7).
This section is divided into two tabs:
- General Configuration – configuration of source, display settings, metadata and text overlays
- Alarms – conditions and outputs for alarms for the station – this is covered in Alarms section of this documentation.
- Status – current status of configured station. gray tab and “no errors” if everything is fine, or red tab and specific errors listed if there is a problem.
General configuration
Station name: the name for the input, can also displayed automatically on the IP Multiviewer mosaic, will also be used when specific source is mentioned – in alarms, API, logs
SNMP Station ID: used for SNMP alarms to identify station. Enter unique number or go to SNMP settings to automatically number/re-number all stations.
Source: select source type, address and optional parameters – that includes video-audio and audio-only sources
Note: source types ending with -AUDIO are for audio-only sources
- MPEG-TS and MPEG-TS-AUDIO: MPEG-TS UDP/RTP – multicast or unicast – from MPTS or SPTS
- Source: for multicast enter address and port number starting with “@” i.e. udp://@224.15.0.1:1234. When using multiple network interfaces, you should specify on which interface the stream is accessible. Enter interface IP right after stream address, separated by space character, i.e. udp://@224.15.0.1:1234 10.10.100.100. To add stream sent as unicast to this machine, use udp://:port ip_address_of_local_interface, i.e. udp://:1234 10.10.100.100
Click to display the content of MPEG-TS (PIDs; programs; audio, video and DVB metadata streams and codecs). - Extract by: filter out a particular program by its DVB Program Name or index or program number. Choose the option, then enter index or name. To check and select ID or Program name used in the stream, click to see the list of programs in the transport stream. Click to reset selection.

- NDI:
- Source: Exact name of NDI source. Use button to find streams available in the local network.
- Channel grouping: enter audio tracks, as they are delivered. Possible options are ST (stereo), 51 (5.1). Separate multiple tracks with commas, i.e. ST,ST,ST equals three stereo tracks.
- CLOCK: analog clock on the screen. If required – use scale and align sliders to move it around the box.
- Time Zone: select one or leave default (system default)
Note: Digital clock is available as on-screen text – see here for details.
- Time Zone: select one or leave default (system default)
- NONE: no video source, empty box that can be used to display digital time or static text
Output: output screen (physical or virtual) to use. Change it to move station to another screen
Left: horizontal position on the screen, left to right, fraction number between 0 and 1. 0 represents the left border of the screen. 1/2 or 4/8 is the middle of the screen.
Top: vertical position on the screen, top to down. Vertical position on the screen, fraction number between 0 and 1. 0 represents the top border of the screen. 1/2 or 4/8 is the middle of the screen.
Width: width of the station. Fraction number between 0 and 1. 1 is full screen width, 1/4 is 25% width.
Height: height of the station. Fraction number between 0 and 1. 1 is full screen height, 1/4 is 25% height.
You can also adjust station size and position in GUI mode – by holding Shift key and moving or resizing the station, or by enabling Design mode – which does not require Shift key.
GPU: a device that will process this stream. In multi-GPU configuration It’s recommended to use the card to which selected screen is connected. Do not overload one GPU or IP Multiviewer will not work properly. In Default mode GPU connected to the screen is used.
Use software decoding: required if source is AVC/H.264 stream encoded with chroma subsampling of 4:2:2 8bit, 4:2:0 10bit or 4:2:2 10bit. You can also use it to offload processing of normal streams to CPU when GPU decoding unit is under full utilization.
Audio meters on the left: layout of the audio tracks displayed on the left side of the screen in IP Multiviewer mosaic. Options:
- all: will display all meters for all tracks available. Below each volume bar presented on the IP Multiviewer screen you will see names of available tracks. It may be useful for finding track names when using custom option
- none: will not present volume meters
- custom: will only display meters for tracks of your choice. Enter the name or PID (dec or hex) for each track and the audio layout, separate with commas. Click to list of audio tracks from the transport stream.
Examples:
- eng = meter for language track “eng”
- eng, pid:128, pid:0×7f = meters for tracks: language “eng”, PID 128 (dec), PID 7f (hex)
Audio meters on the right: same as above, but placed on the right side of the screen.
Audio meters at the bottom: same as above, but placed at the bottom the screen. Recommended for audio-only sources.
Audio meters – minimum volume of meter: defines how the meter will be scaled
Audio meters – meter height: Select one
- Full – height of the volume bar is the same as the height of video box
- Scaled – volume height will be scaled to follow size of the video inside the video box
Loudness meter – scale: Select from 50 to 400%
Loudness meter – font scale: Select from 50 to 400%
Audio output tracks to speakers: IP Multiviewer can send the selected audio tracks to the main audio output (sound card, HDMI or DP audio output). Do not use the feature if the IP Multiviewer server has no audio card. Selected tracks will be sent to internal Audio Mixer.
Audio output tracks to TS/SRT: controls if selected audio tracks should be embedded (using AAC codec) in MPEG-TS UDP or SRT Net Stream.
Audio output tracks to Web: controls if selected audio tracks are available (using AAC codec) in Web output of Net Stream.
DVB subtitles: controls display of DVB subtitles:
- all: subtitles of all available languages will be presented. Use with show labels option to see track language identifiers.
- none: subtitles will not be displayed.
- custom: only subtitles of your choice will be presented. Enter three letter language identifier for subtitles track you want to see.
- show labels: will display subtitle language identifiers
- show brackets: when checked, subtitles will be presented with surrounding brackets. This is useful for diagnostic purposes and to indicate that subtitles are displayed by IP Multiviewer using DVB subtitles track and were not “burned in” on the picture.
- alt. timing: when checked, subtitles are not synchronized to PCR, but presented once they are delivered with the stream
DVB Teletext subtitles:
- none: subtitles will not be displayed
- teletext page: Enter teletext page number where subtitles are broadcasted
- EIA 708 closed captions: enable or disable display of EIA 708 closed captions
- none: EIA 708 CC will not be displayed
- enabled: EIA 708 CC will be displayed
Text fields: Text top left / top center / top right / center / bottom left / bottom center / bottom right: configuration for text labels displayed
Labels are organized with HTML-like tags. These can be parameters to see on the screen, and/or displayed messages format (style).
To get the list of available tags, simply click on the button located above each of Text fields. Click the tag on the list, and it will be copied to text field
Built-in presets for most used messages are available under the button. Select one from the list, to fill Text field with combination of tags.
Scale: the scale factor of the presented video. The default value is 100% – it means the video will touch the sides of the box. Scaling down allows placing text labels and meters outside of the video.
Video align – horizontal: Moves scaled picture left / right inside the video box.
Video align – horizontal: Moves scaled picture up / down inside the video box.
Override automatic delay control: allows a stream to appear on the screen earlier or later than it should be based on PCR. Check this option, then enter delay and delay spread in milliseconds. For MPEG2 sources or when audio output is used – set it to 500 / 50.
Override automatic audio delay control: manually configure delay between audio and video.
Alternative scaling: use when interlaced video is displayed with distortions – corrects scaling bug in NVIDIA driver but consumes more GPU 3D processing power
Blur: when checked, video is blurred
Box border thickness / color / opacity: each added source is placed on the screen in a box that can have its own border. It may be useful when scaling down the presented video. Move the sliders to change border thickness and opacity. Enter a hexadecimal color number for the border, or click on coloured box next to the input field to select from the pop-up color palette.
Box border on error thickness / color / opacity: controls styling of the box border for error notification.
Hide warning icons: when checked, it will hide orange warning icons that appear over the box when performance problems are detected.
Once you finish the General Configuration, you can set up Alarms or apply the configuration. You can also click on top of the config screen to apply new configuration to the screens.
