HDMI I/O (NV-32-H)

Use the HDMI I/O component to configure HDMI video and audio routing in Q-SYS.

Note: To learn about native HDMI distribution within the Q-SYS Ecosystem, see the Q-SYS Video 101 Training on the QSC website.

Note: Mediacast functionality described in this topic is not supported in Q-SYS version 9.4.x LTS.

These Q-SYS devices support HDMI video and audio routing.

In this mode, the HDMI I/O component represents a local 3 x 2 HDMI video switcher with the ability to receive and locally display Mediacast streams. Q-SYS Shift Networked AV Streaming is not supported.

Mediacast Streaming

  • Select a single incoming Mediacast stream from an NC Series or PTZ Series camera to display locally on HDMI AV Output 1. Display on HDMI AV Output 2 is not supported.
  • Camera Mediacast streams are always in 16:9 aspect ratio and scaled to "stretch to fit" mode for displays that are not 16:9.

Local HDMI Switching

  • Onboard HDMI switching is 3 x 1 @ 4K60 or 3 x 2 @ 1080p.

For NV-32-H (Core Capable) devices in Peripheral Mode or NV-32-H Network Video Endpoints, the HDMI I/O component represents a single NV-32-H device configured as an Encoder or Decoder for sending or receiving AV signals over the network.

Q-SYS Shift Networked AV Streaming

  • An Encoder takes source HDMI AV signals and places them on the network in streams. Encoders can process a single stream up to 4K60 or three simultaneous streams up to 1080p60 each.
  • A Decoder processes incoming network HDMI signals and sends them to a display. Decoders can process a single stream up to 4K60 or two simultaneous streams up to 1080p60 each.

Mediacast Streaming

  • Select a single incoming Mediacast stream from an NC Series or PTZ Series camera to display on the Encoder or Decoder's local HDMI AV Output 1. Output 2 is not supported with Mediacast streams.
  • Mediacast streaming is local to the NV-32-H device. You cannot stream Mediacast between Encoder AV Outputs and Decoder AV Inputs in your design.
  • Camera Mediacast streams are always in 16:9 aspect ratio and scaled to "stretch to fit" mode for displays that are not 16:9.

Local HDMI Switching

  • For Encoders, use HDMI Output 1 as a “courtesy monitor”, displaying any of the three locally connected HDMI sources at resolutions up to 4K60.
  • For Decoders, toggle between network streams or locally connected HDMI sources (single 4K60 or dual 1080p60 sources).
  • QSC supports the direct connection between NV Series Video Endpoints and HDMI sources and displays.
  • The use of signal extension solutions (for example, HDBaseT extenders, HDMI distribution amps, and active/optical HDMI cables and keystones) in-line with NV Series HDMI ports may introduce handshake issues or signal attenuation-related issues. QSC does not test any configurations with these products.
  • To maximize HDMI signal reliability, use Premium or Ultra High Speed certified cables.
  • QSC does not conduct testing with HDMI cables longer than 6 feet. All testing is based on connections using cables shorter than 6 feet between NV Series Video Endpoints and HDMI sources and displays.

Note: Each NV Series HDMI output supplies up to 120mA on the +5v signal line.

Note: The input and output pins shown depend on the Q-SYS hardware and component Properties.

HDMI Source Examples

When the NV-32-H (Core Capable) is configured in Core Mode, the device serves not only as an integrated audio, video, and control processor (as with other Q-SYS Core processors) but also as a local HDMI switcher. In this example, the NV-32-H (Core Capable) accepts HDMI connections from three conference room user laptops and routes the HDMI signals to the conference room monitor.

This example shows a typical conference room configuration. Three HDMI source signals (for example, computer HDMI audio and video) can be encoded by one NV-32-H network endpoint mounted under a conference room table. The signals are transmitted over the Q-LAN network and decoded by another NV-32-H connected to a wall-mounted HDMI display. Whatever network AV source selected in the Decoder is sent to the display, with amplification of two channels of audio from the selected source.

This example is similar to Example 1, except that a "courtesy" monitor is connected to the HDMI 1 output on the NV-32-H Encoder. This allows a presenter to select one of the HDMI sources for viewing on a separate monitor. For example, this would be useful for a lecturer to view the presented source on a small lectern monitor without having to turn around to see the main display.

Note: Audio from an Encoder's local HDMI 1 output can also be routed to Q-SYS audio components for processing in the Q-SYS Core's DSP. To enable HDMI and audio output pins on an Encoder, set the HDMI Output Mode property to "HDMI 1" and set the number of HDMI 1 Audio Pins.

Tip: You can also route audio directly from an HDMI source by enabling Breakaway Audio for that source. For more information, and to see an example, see Generic AV Source.

This example adds the ability to connect up to three local HDMI sources to the NV-32-H Decoder, such as Blu-ray players, network streaming devices, and similar. Users can thus select from six AV sources (three network, three local) to display in the room, with amplification of the selected source.

In this example, the room contains two HDMI displays. Each can display a separate network AV source. Audio from both sources is routed to a Matrix Mixer and is then amplified.

Note: To enable HDMI Output 2 pins on a Decoder and route separate AV streams to dual displays, set the HDMI Output Mode property to "HDMI 1 + HDMI 2".

Tip: You can also route audio to a display by exposing audio input pins for that display. This can be useful, for example, for inserting audio from a Q-SYS PA system (pages) for output on a display's internal speakers or a connected speaker bar. For more information, and to see an example, see Generic HDMI Display.

In this example, the primary room's NV-32-H is sending unicast streams on its AV Output 1 and 2 pins. However, AV Output 3 is sending a stream to both the NV-32-H in the primary room and a secondary location, thus making this a multicast stream. In the secondary location, the stream is decoded and output to an HDMI display. This location has no amplifier and speakers, so the stream audio is heard via the display's internal speakers or connected speaker bar.

Note: For more NV-32-H schematic examples showing different configurations for HDMI sources and displays, see Generic AV Source and Generic HDMI Display.

Mediacast and HDMI Source Examples

In this example, one Mediacast camera source and three local HDMI sources are wired to an NV-32-H (Core Capable) in Core Mode. Any of these sources is selectable for output to a connected HDMI display.

In this example:

  • A Mediacast camera source is selectable for display on both an Encoder's local HDMI Output 1 and a Decoder's HDMI Output 1.
  • Three HDMI devices connected to the Encoder are selectable on the Decoder as AV sources.
  • Two HDMI devices connected to the Decoder's local HDMI inputs are selectable as HDMI sources.

Tip: Camera Offline, Privacy, and Exiting Privacy graphics are displayed on the HDMI output when a Mediacast camera stream is selected for output.

This example is the same as Example 8, but with simultaneous Mediacast signal routing to three USB Video Bridges.

Tip: Mediacast sources can be routed to HDMI simultaneously with USB audio and video bridging with no impact to device performance.

In this example, three Mediacast camera streams are selectable for the display connected to a Decoder, along with three AV streams and two local HDMI sources.

Note: HDMI Output 2 does not support Mediacast streams.

In this example, two Mediacast camera streams are selectable for the display connected to a Decoder. One Mediacast router switches camera streams into the Encoder HDMI I/O.

In this example, two Mediacast camera streams are selectable for the display connected to a Decoder. HDMI I/O Embedded Mediacast router switches cameras streams directly.

In this example, Mediacast router switches camera streams into the single Mediacast input of the Encoder HDMI I/O, Encoder USB Video Bridge, and Decoder HDMI I/O.

Note: Available properties depend on the Supported Q-SYS Hardware and mode, if applicable.

Core Properties

Name

The Name may contain ASCII letters 'a' through 'z' (case-insensitive), the digits '0' through '9', and the hyphen. Names cannot begin or end with a hyphen. No other symbols, punctuation characters, or blank spaces are permitted.

Note: This name must match the Hostname for the Core as defined in Core Manager. If you use Telnet or third-party external control, you must enter the Name exactly as it is entered here.

Location

User-defined name that groups the component with other components in the same physical location – for example, "Rack 1" – or in the same organizational scheme.+

Is Required

When enabled, and the device is not found on the network, the device is reported as 'Missing', which is an error condition. This is the default behavior. When disabled, and the device is not found on the network, the device is reported as 'Not Present', which is not an error condition. This option only appears when NV-32-H is set to Encoder or Decoder; it does not appear when set to Core Mode.

Dynamically Paired

Indicates that this virtual component can be paired with the same type of hardware without changing the network ID of the hardware or the name of this component. Refer to the Q-SYS Core Manager Dynamic Pairing topic for more information. The default is 'No'. This option only appears when NV-32-H is set to Encoder or Decoder; it does not appear when set to Core Mode.

Model

Select your Q-SYS Core processor model. See HDMI I/O (NV-32-H) for a list of selectable Core models. This option only shows when NV-32-H is set to Core Mode; it does not appear when set as Encoder or Decoder.

External USB Audio

When enabled, you can connect an external audio device to the USB input and route audio to and from that device. See External USB Audio Device In and External USB Audio Device Out.

Network Receive Buffer

Adds extra buffer time to the default maximum of 1 ms.

Additional Network Receive Buffer time is useful in (rare) cases where the network latency through the network exceeds the default maximum. Additional network latency my be introduced by sub-optimal QoS functionality, some layer-3 routing implementations, long distances or large networks.

Because the specified additional latency is added both to transfers from IO Frames to the Core and from the Core to IO Frames, the additional system latency is twice the amount of additional receive buffer selected. Total system latency based on this setting is calculated and displayed immediately below the Network Receive Buffer property.

This option only shows when NV-32-H is set to Core Mode; it does not appear when set as Encoder or Decoder.

HDMI / Shift AV

Device Type

Can set the NV-32-H as Core Mode, Decoder, or Encoder.

Note: When deploying a design to an NV-32-H (Core Mode) that changes the operational mode from either Core Mode to Encoder, Encoder to Core Mode, or Encoder to Decoder, or Decoder to Encoder, the device will automatically be rebooted.

HDMI Output Mode

This property determines the functionality of the NV-32-H HDMI outputs.

HDMI 1 Audio Pins

If enabled in the component Properties (HDMI Output Mode is set to "HDMI 1 + HDMI 2"), select the number of audio pins to expose – from 0 to 8 – for routing to other Q-SYS audio components, such as a network amplifier. This audio corresponds to the HDMI Output 1 or 2 source you select in the HDMI I/O control panel.

Tip: These pins automatically send audio for whatever HDMI video source is selected for display. No additional programming is required to align audio and video signals.

Source Index

Select how control indexes are determined for each NV-32-H streaming component in your design, including HDMI I/O (NV-32-H), Status (NV-32-H), and System Link. This affects how controls are referenced in scripting components, including Named Controls in Block Controller and Text Controller.

  • Auto: (Default) Components in existing designs upgraded to Q-SYS v9.2.0 and later will continue to use a 0-based index. New components use a 1-based index, which matches the functionality of other Q-SYS components.
  • 0-Based: The component will use a 0-based index, meaning that control indexing starts at 0. This is useful for maintaining consistency with other components and for re-using control scripts.
  • 1-Based: The component will use a 1-based index, meaning that control indexing starts at 1. This matches the functionality of other Q-SYS components.

For a control called "Select AV 1" in the control panel:

  • 0-Based: The control would have an index value of 0. As in, hdmi.out.0.select.avh.0.
  • 1-Based: The control would have an index value of 1. As in, hdmi.out.1.select.avh.1.

Device Type

  • 1-Based: The control would have an index value of 1. As in, hdmi.out.1.select.avh.1.

Device Type

Can set the NV-32-H as Core Mode, Decoder, or Encoder.

Note: When deploying a design to an NV-32-H (Core Mode) that changes the operational mode from either Core Mode to Encoder, Encoder to Core Mode, or Encoder to Decoder, or Decoder to Encoder, the device will automatically be rebooted.

AV IP Streaming

For Encoders only, this property determines the network streaming method for Q-LAN AV streams:

  • Compiler Choice: (Default) Select this option to allow Q-SYS Designer Software to determine whether unicast (one-to-one) or multicast (one-to-many) is best for your configuration. This is the recommended option.
  • Unicast: Select this option when your design contains one-to-one AV routing, meaning that each AV output pin in your design is connected to a single AV input pin.
  • Multicast: Select this option when your design contains one-to-many AV routing, meaning that an AV output pin is connected to multiple AV input pins.

HDMI Output Mode

This property determines the functionality of the NV-32-H HDMI outputs.

  • HDMI 1: (Default) Video and audio output is enabled for the HDMI 1 output connector.
  • HDMI 1 + HDMI 2: Video and audio output is enabled for both the HDMI 1 and HDMI 2 output connectors. Each output can be assigned an independent source.

  • 1-Based: The control would have an index value of 1. As in, hdmi.out.1.select.avh.1.

Mediacast

Input Count n

The number of Mediacast inputs is configurable in Properties. Connect this pin directly to the Mediacast Output pin of the Status/Control (Cameras) component or, for designs with multiple Mediacast sources, to the Output pin of the Mediacast Router component.

USB Bridging

These properties appear based on the USB bridging capabilities of the Q-SYS device. Refer to the USB Video Bridge and USB Audio Bridge topics to see what Q-SYS Core processors and peripherals support USB bridging.

USB Bridge Name

User-defined name given to the USB Bridge, from 1 to 24 characters. The Name may contain ASCII letters 'a' through 'z' (case-insensitive), the digits '0' through '9', and the hyphen. Names cannot begin or end with a hyphen. No other symbols, punctuation characters, or blank spaces are permitted. This option only appears when the NV-32-H is set to Core Mode; it does not appear when set as an Encoder or Decoder.

Zoom Compatibility

If you are using the HID Conferencing component to control a remote computer running Zoom, set this property to 'Enabled.' Otherwise, when controlling another conferencing app such as Skype for Business, set to 'Disabled' (default). When this property is enabled, the USB Bridge Name property is disabled, and the USB Bridge automatically uses the name of the device for compatibility with Zoom's allowed device list – for example, "Q-SYS Core 110f" or "Q-SYS NV-32-H".

Tip: Enabling Zoom Compatibility may improve the user experience with macOS conferencing solutions.

USB Video Bridge

Enable the USB Video Bridge to bridge Q-SYS Mediacast streams to USB, enabling you to view Mediacast video on a connected computer. This exposes the USB Video Bridge component in the I/O-USB Bridge Inventory tree. To see what Properties are available when the USB Video Bridge is enabled, see USB Video Bridge.

UVC Camera Control

When this is enabled (disabled by default), the camera can be controlled by far-end third party applications which support Relative Movement Commands. When disabled, the cameras cannot be controlled by the applications.

Video Formats

See Video Formats for more information.

USB Audio Bridge

Provides the capability of passing audio via USB. When this is set to anything except 'Disabled', you can drag the Speakerphone and/or Sound Card components from the device's Inventory tree into your design. To see what Properties are available when the USB Audio Bridge is enabled, see USB Audio Bridge.

  • Disabled: (Default)
  • Speakerphone (1 x 1): Provides a speakerphone with an input and output component, each having 1 audio connection.
  • Sound Card (2 x 2): Provides a sound card with an input and output component, each having two (stereo) audio connections.
  • Speakerphone and Sound Card: Provides one speakerphone and one sound card with the same capabilities as described above.
  • Advanced – If supported, allows up to any combination of four speakerphone / sound cards.

Graphic Properties

Label

Use the Label property to change the name of the component in the schematic. The Label property defaults to the component name. To learn more about renaming schematic elements, see Organizing Your Design.

Position

The coordinates reference a specific place in the schematic - for example,"100,100" (horizontal, vertical). 0,0 is the upper left corner of the schematic.

Fill

Sets the fill color of the component in the schematic.

Script Access Properties

Code Name

Displays the currently assign name for control access. You can use the auto-assigned name or customize it. Q-SYS will automatically check all Code Names in the design to ensure name is unique.

Script Access

Defines whether the component will be accessible by script and/or externally, or not at all. Choices include All, External, None (default), and Script.

Tip: Use Script Programmer Mode to quickly view the Script Access setting directly on the component in the design schematic without the need to disconnect from the Q-SYS Core processor.

Note: Available controls depend on the Supported Q-SYS Hardware, mode, and whether the HDMI I/O component is configured as an Encoder or Decoder (if applicable).

HDMI Output 1, 2 Source

Select which sources to output through the Decoder's HDMI AV Output pins. The section for HDMI Output 2 Source only appears when the HDMI Output Mode component property is set to "HDMI 1 + HDMI 2". You can select a source using either the drop-down menu, numeric input, or trigger buttons. The Active HDMI LED indicates what sources are active and selectable.

  • Graphic 1, 2, 3: Toggle a graphic to display that you assign in Q-SYS Core Manager. Numeric input values are 1, 2, and 3.
  • HDMI 1, 2, 3: These inputs correspond to the sources connected to the HDMI AV Input pins 1, 2, 3. Numeric input values are 4, 5, and 6.
  • Mediacast In n: (HDMI Output 1 Source only) These inputs correspond to the Mediacast sources (cameras) connected to the Mediacast Input pins. The number of selectable sources equals what is specified for the Mediacast > Input Count property. Numeric input values begin at 7.
  • Follow H1: (HDMI Output 2 Source only) If the HDMI Output Mode property is set to "HDMI 1 + HDMI 2", this control appears for the HDMI Output 2 Source. When enabled, HDMI Output 2 uses whatever source is selected for HDMI Output 1. When enabled, the maximum resolution is 1080p60 for both outputs.

Encoder Network Settings

IP Streaming

LED indicates whether the Encoder is actively transmitting AV audio and video data to a Decoder via SRTP on the Q-LAN network. This applies to both unicast or multicast streams.

SRTP Address

Displays the IP address that the Encoder is using to send AV network audio and video streams directly to Decoders:

  • For unicast streams, this is the Encoder's IP address.
  • For multicast streams, this is the multicast address assigned in Core Manager.

Bitrate (Mbps)

Specify the maximum average network video bitrate the Encoder can use to send AV streams to Decoders, from 50 to 800. The default is 750.

Lower bitrates consume less network bandwidth, but at the expense of compromised video quality during fast motion and transitions. For acceptable video quality:

  • 4K60 stream – set the bitrate to at least 650 Mbps.
  • 1080p streams – set to the bitrate so that each stream can use at least 250 Mbps.

Note: The Bitrate value is shared across all AV streams. For example, if you set the Bitrate to 600, the first AV stream can use a maximum of 600 Mbps. If a second stream becomes active, both streams can use 300 Mbps. If a third stream becomes active, each stream can use 200 Mbps.

Ref Frame Interval

This value determines how often video artifacts introduced by network errors are eliminated in the video stream. The value, between 90 and 255, is the number of video frames before a complete refresh occurs. The default is 90. A longer interval results in a lower video bitrate (thus consuming less network bandwidth), but at the expense of video artifacts persisting during the interval.

Encoder Mode

This property determines the maximum allowed AV stream resolution and what happens when the Encoder video streaming capabilities are exceeded.

  • 4K60 max - One Hot Plug Event: (Default) This option allows a maximum stream resolution of 4K60. However, because an Encoder is limited to processing a single stream at resolutions above 1080p60, a request from a Decoder to process an additional AV stream on another input triggers a "hot plug event." Any Encoder input EDID with a resolution greater than 1080p60 is automatically re-negotiated down to 1080p60 maximum, thus allowing the Encoder to provide up to three streams. When this occurs, there is a momentary disruption of video processing across all AV streams. This negotiation and disruption mimic what occurs when unplugging and plugging back in an HDMI cable, hence the term. When all AV inputs become idle, the source EDIDs then reset to allow resolutions greater than 1080p60 again. Additionally, when wired to a dual output NV-32-H decoder, the encoder mode will switch to 1080p until the source is removed and the AV route is cleared.
  • 1080p60 max - No Hot Plug Events: This option limits all streams to 1080p60 maximum. Because an Encoder can process three simultaneous streams up to 1080p60, there is no EDID re-negotiation when a Decoder requests subsequent streams. Wiring an encoder to a dual output NV-32-H will force this mode, limiting the input EDID on the encoder to 1080p or lower, which cancels most 21:9 resolutions, especially 3440x1440.

HDMI Output 1 Source

This section only appears when the HDMI Output Mode component property is set to "HDMI 1". Select which source to output through the Encoder's HDMI AV Output 1 pin. You can select a source using either the drop-down menu, numeric input, or trigger buttons. The Active HDMI LED indicates what sources are active and selectable.

  • Graphic 1, 2, 3: Toggle a graphic to display that you assign in Q-SYS Core Manager. Numeric input values are 1, 2, and 3.
  • HDMI 1, 2, 3: These inputs correspond to the sources connected to the HDMI AV Input pins 1, 2, 3. Numeric input values are 4, 5, and 6.
  • Mediacast In n: These inputs correspond to the Mediacast sources (cameras) connected to the Mediacast Input pins. The number of selectable sources equals what is specified for the Mediacast > Input Count property. Numeric input values begin at 7.

HDMI Outputs

Select which sources to output through the Decoder's HDMI AV Output pins. The section for HDMI Output 2 Source only appears when the HDMI Output Mode component property is set to "HDMI 1 + HDMI 2". You can select a source using either the drop-down menu, numeric input, or trigger buttons. The Active AV LED indicates what sources are active and selectable.

  • Graphic 1, 2, 3: Toggle a graphic to display that you assign in Q-SYS Core Manager. Numeric input values are 1, 2, and 3.
  • HDMI 1, 2, 3: These inputs correspond to the sources connected to the HDMI AV Input pins 1, 2, 3. Numeric input values are 4, 5, and 6.
  • AV 1 - n: These inputs correspond to the sources connected to the AV Input pins, where n is the value specified for the AV Input Count property. Numeric input values range from 7 to 9, depending on what is specified for the AV Input Count property.
  • Mediacast In n: (HDMI Output 1 Source only) These inputs correspond to the Mediacast sources (cameras) connected to the Mediacast Input pins. The number of selectable sources equals what is specified for the Mediacast > Input Count property. Numeric input values range from 8 to 10, depending on what is specified for the AV Input Count and Mediacast Input Count properties.
  • Follow H1: (HDMI Output 2 Source only) If the HDMI Output Mode property is set to "HDMI 1 + HDMI 2", this control appears for the HDMI Output 2 Source. When enabled, HDMI Output 2 uses whatever source is selected for HDMI Output 1. When enabled, the maximum resolution is 1080p60 for both outputs. Its numeric input value is one count after the last AV input value.

Note: Available controls depend on the Supported Q-SYS Hardware, mode, and whether the HDMI I/O component is configured as an Encoder or Decoder (if applicable).

Encoder Mode switching to 1080p when using dual output NV-32-H Decoder

When making AV routing changes, the encoder mode may switch from 4K to 1080p if wired to a dual output NV-32-H decoder. Dual NV-32-H output decoders will set all connected encoders to 1080p max mode until the source is removed and the AV route is cleared, or if multiple streams have stopped. This means that streaming to an NV-32-H dual output decoder will limit the input EDID on the encoder to 1080p or lower, which cancels most 21:9 resolutions, especially 3440x1440.

To avoid this, either live with a lower quality 21:9 resolution (1920x800) or disable all NV-32-H dual outputs to a single output.

Garbled video when switching AV sources

If your design contains an NV-32-H Encoder that is multicasting to multiple NV-32-H Decoders, you may experience temporary (1-4 seconds) garbled video when switching AV sources. This is due to improper IGMP settings on the network switch. You must enable the IGMP "fast-leave" option.

Refer to the Multicast Traffic topic for other IGMP requirements for network switches.

Mediacast is not a selectable source for HDMI Output 2

This is by design. Only HDMI Output 1 supports Mediacast streams. HDMI Output 2, even when the source is set to Follow H1, does not support Mediacast streams, See Supported Q-SYS Hardware.

Error message when selecting Follow H1 on HDMI Output 2 when HDMI Output 1 is showing a Mediacast source

This is also by design. HDMI Output 2 cannot display a Mediacast source via Follow H1.

Mediacast camera stream stretches to fit the screen (not letter-boxed)

This is normal. Mediacast camera streams are natively 1080p with a 16:9 aspect ratio. On a non-16:9 display, the stream will fill the screen and will not be letter-boxed.

Auto Privacy mode is not working with a camera sending a Mediacast camera stream to an NV-32-H

This is normal. If a camera's Mediacast Output pin is connected to both a downstream USB Video Bridge and HDMI I/O Mediacast Input pin, whether directly or through a Mediacast Router, Auto Privacy in the USB Video Bridge is not supported. Manual privacy is supported, however.
