Generic AV Source

In an AV distribution topology using Q-SYS NV-32-H network video endpoints, the Generic AV Source component represents the beginning of the HDMI signal chain.

Input Pins

This component has no input pins.

Output Pins

AV Output

This pin represents the audio and video signals from the HDMI source. Connect this pin to one of the HDMI input pins of the HDMI I/O (NV-32-H) component or AV I/O (NV-21-HU) component. HDMI video and embedded audio signals are routed directly through the NV-32-H or NV-21-HU network video endpoint without the need for Q-SYS Core processing. Additionally, this pin can be connected to the USB-C input of the AV I/O (NV-21-HU) component.

Note: You cannot wire a Generic AV Source component directly to a Generic HDMI Display component.

Breakaway Channel

When 'Breakaway Audio' is enabled in Properties (after connecting the Generic AV Source to an Encoder/Decoder), each pin represents one channel of audio that you can route to other Q-SYS audio components, such as a network amplifier. This audio is a copy of the audio embedded within the HDMI stream, and is sent over the network to the Q-SYS Core for processing. Enable breakaway channels if you always want to hear audio from an HDMI source regardless of which output signal the HDMI I/O Decoder component is sending to a Generic HDMI Display component.

Note: For additional schematic examples, see the HDMI I/O (NV-32-H) and AV I/O (NV-21-HU) topics.

Note: For more NV-32-H and NV-21-HU schematic examples showing different configurations for encoders, decoders, and displays, see HDMI I/O (NV-32-H), AV I/O (NV-21-HU), and Generic HDMI Display.

Generic AV Source 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.

Location

User-defined name that groups the component with other components in the same physical location, or in the same organizational scheme.

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.

• None (default) - Not accessible by any script, plugin, or by Q-SYS Remote Control Protocol (QRC).
• Script - Can be accessed by scripts, such as Text Controller, Block Controllers, and plugins only.
• External - Can only be accessed by 3rd party controls systems using component commands from the Q-SYS Remote Control Protocol (QRC).
• All - No restrictions, can be accessed by 3rd party control systems via Q-SYS Remote Control Protocol (QRC), or script objects or plugin objects.

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: You must wire the source's HDMI AV Output pin to a NV-32-H or NV-21-HU HDMI AV Input pin to expose the source controls.

Status

Component status is conveyed with the Status LED and Status box, which uses both color and text to indicate the current condition:

• OK: The device is functioning normally.
• Initializing: The device is in the process of a firmware or configuration update, or the design is starting.
• Compromised: The device is functioning, but a non-fatal problem exists. Refer to the Status box for details.
• Missing: The device cannot be discovered.
• Fault: The device is malfunctioning or is not properly configured. Refer to the Status box for details.
• Unknown: This status appears during a Core reboot (for example, during a firmware update), or when a design is being uploaded to the Core and before it has started running.
• Not Present: If applicable to the device, this status appears when the device is not connected to the network and its Is Required component property is set to 'No'. This status also appears if the device component's Dynamically Paired property is set to 'Yes', pairing has not been assigned in Core Manager, and the device component's Is Required property is set to 'Yes'. See Dynamic Pairing.

HDMI AV Output

Cable Detect / Valid Format

LED indicates whether the HDMI input is receiving video that is compatible with Q-SYS. If this LED is not lit, it means that video is not detected on the input, is present but corrupt, or the video format is incompatible with the current operating mode - for example, a 4K60 signal is detected but 1080p60 is configured as the maximum format.

Tip: "Auto selection" scripts can use this LED as an indication that an input is active and usable.

Video Format

Displays the detected HDMI source resolution and frame rate. If the video format is incompatible (for example, interlaced input), invalid, or unrecognizable, the status indicates "Invalid".

Aspect Ratio

Displays the detected aspect ratio of the source video – for example, "16:9".

Active Audio Channels

Displays the number of active, valid, and usable embedded audio channels detected in the HDMI source video.

EDID

EDID files include properties for supported video resolutions, frame rates, number of audio channels, and audio formats. Select an EDID file to apply to the HDMI source, which is then sent to the NV-32-H encoder input. Q-SYS uses standard EDID files (with file extension .qedid) to tell HDMI sources what audio and video formats are compatible with the NV-32-H system. If you save a display's EDID file to the Q-SYS Core (using the Generic HDMI Display component's 'Save EDID to Core' control) or upload an EDID file in the Q-SYS Core Manager Video > Video Endpoints page, those EDID files also appear in this list and use the .bin file extension.

Note: Settings within EDIDs can be dynamically changed on the NV-32-H inputs depending on how you configure the NV-32-H – see the 'Max Supported Format' control and the 'Audio Channels' property.

Max Supported Format

Indicates the maximum video format supported in the current operating mode. There are two configuration scenarios in which the NV-32-H cannot accept video formats that exceed 1920x1080p60:

• If you set the NV-32-H I/O Decoder design property HDMI Output Mode to 'HDMI 1 + HDMI 2', both HDMI outputs are limited to 1920x1080p60 and smaller resolutions.
• If you set the NV-32-H I/O Encoder control Encoder Mode to '1080p60 max - No Hot Plug Events', all HDMI inputs wired to the encoder are limited to 1920x1080p60 and smaller resolutions.

Enable Output

Click to toggle Hot-Plug Detection (HPD) from the HDMI source. This is enabled by default. When Enable Output is toggled off, HDMI signals from the source are disabled and its status changes to "Not Present", which is the same behavior as physically disconnecting the source's HDMI cable.

Tip: Toggling Enable Output is useful, for example, if you have a PC with two HDMI outputs connected to an NV-32-H and you want to force the PC to use either single display mode (toggle off Enable Output on one of the outputs) or dual display mode (toggle on Enable Output on both outputs).

Hot-Plug Trigger

This resets the HDMI interface without having to physically disconnect and reconnect the source's HDMI cable. If you are experiencing HDMI signal issues, try pressing this button.

HDCP Mode

Select whether the NV-32-H HDMI input negotiates and authenticates HDCP with the source:

• Auto: (Default) Allows the source to negotiate HDCP 1.4 or 2.2 with the NV-32-H HDMI input. Note that when a source sends protected content, authentication can interrupt the video signal for up to 30 seconds.
• Off: The NV-32-H HDMI input does not negotiate HDCP with its source. The source cannot send protected content to the input.

CAUTION: Many sources do not provide notification of HDCP authentication failures and instead send black video, making it difficult to diagnose video issues. Use the 'Off' mode with care.

HDCP Status

Displays the HDMI input's HDCP negotiated state.

HDCP Encryption

LED indicates whether HDCP encryption is active on the source's HDMI output.

HDMI Audio

This section shows information for all HDMI source audio channels, as configured in the 'Audio Channels' property.
