Yes. All audio tracks must have the same sampling rate and bit depth if you plan to output multiple audio tracks simultaneously from either audio or video files.

You can mix multiple audio files together (for example, by adding multiple zones in BrightSign Author) and send them to the same output, or output two audio streams simultaneously: one via the HDMI, and a second via the 3.5mm audio or SPDIF using an .mp3 or .wav file.

The AU335 supports up to three zones for audio. For example, you can create two analog-output zones, but one is stereo right and the other is stereo left. Or, you can create two zones where one is analog and one is HDMI.

See this page to make sure your audio format is supported.

Series 2, 3, 4 and 5 BrightSign players do not support component or composite video without an external converter.

HD810 and HD1010 players come installed with YPbPr component connectors. Using a third-party VGA converter, you can also play component and composite video on other models.

There are many third-party VGA breakout cables; however, some VGA breakout cables will not work with the VGA port on a BrightSign player. You will need to ensure that the VGA converter you purchase has the same pin layout as outlined below:

In BrightSign Author or , configure the output for component/composite as follows:

Component:  Select Component from the Connector type drop down menu. In the Screen resolution drop down menu, you may choose any 1080,  720, or 480 option, as well as the NTSC-COMPONENT and PAL-COMPONENT options.

S-Video or CVBS: Select HDMI from the Connector type drop down menu. In the Screen resolution drop down menu, you may choose the following options:

You can use MediaInfo to check if your files are compatible with a player. To do this:

BrightSign Support will ask you to send the above information (in the above Text View format) if you contact us and we suspect that your audio/video files are impacting your player's behavior.

When using H264 encoded video please make sure that you check the Format profile (Format profile: [email protected] in the above example) and that it is within the specs described on this page.

You can synchronize models from the same model family: For example, the HD1020 can be synced with the HD220, or the 4K242 with the 4K1142.

However, you cannot synchronize models from different model families: For example, the XD230 cannot be synced with the XD232 or HD220.

Players must be synchronized over an Ethernet connection (not WiFI). You can synchronize two units by connecting them directly to each other using a standard Ethernet cable; for any larger deployments, you will need LAN infrastructure.

See this page for more information on synchronization.

The low_latency parameter for RTSP streams, on BrightSignOS version 6.2 and above, lets you achieve a much lower streaming latency than normal, but at reduced maximum bitrates (for example, rtsp://example/media.amp?low_latency). This option is ideal for IP camera streams on the local network.

Genlock (frame-accurate VSync) is available with BrightSignOS version 7.0 and is automatically integrated in all BrightWall™ and Enhanced Synchronization presentations as of  version 4.7.1.x or later.

The current version of BrightSign Author doesn't support BrightWall™, but does support Enhanced Synchronization. BrightAuthor Classic versions 3.8.0.x or later support BrightWall™. BrightSign Author and BrightAuthor Classic can be installed and used on the same computer. 

Note that synchronization is not supported over wireless connections.

You must use a plugin or script to play USB audio with BrightSign players. Digital audio output is supported over HDMI and SPDIF.

Yes, you can use any of the following methods:

BrightSign players do not support videos that have a width or height less than 64 pixels. However, a video can be scaled down beyond this limit by making the BrightSign Author or  zone or HTML video element containing the video smaller than 64x64. To get the desired downscaling behavior, ensure that the View Mode of the zone is not set to Fill Screen and Centered, or that the element does not have an object-fit=cover attribute. 

Using the BrightWall or Enhanced Synchronization features, players stay synchronized within a few milliseconds (i.e. video and images remain frame-accurate among screens). See this page to determine which synchronization option is best for your needs.

The current version of BrightSign Author doesn't support BrightWall™, but does support Enhanced Synchronization.  versions 3.8.0.x or later support BrightWall™. BrightSign Author and BrightAuthor Classic can be installed and used on the same computer. 

See this page for more information.

BrightSign recommends that you encode the video using the hardware encoder, rather than software encoder (note that hardware encoding in Adobe Media Encoder doesn’t support interlaced output*)*. To do this:

Other Adobe Media Encoder settings that work for Series 2 and later players are:

If the video mode is set to "auto," BrightSign players will set the highest video mode based on your connected hardware. However, “Auto” on XD5 or HD5 players will set to the best general resolution that can cope with any type and combination of content of for these platforms, not the highest resolution. For example, the “auto” setting on an XD5 or HD5 will be set to HD, not 4K.

BrightSign support for Web Audio is based on the hardware capability of the player, not software. Series 4 players and older are not capable of supporting Web Audio.

BrightSign Series 5 and Series 6 players support the Web Audio API when audio is played inside the Chromium HTML engine. However, audio produced by the native BrightSign media pipeline (e.g., BrightSign Author video zones or BrightScript playback) cannot be used as a Web Audio AudioNode; only audio created and played within Chromium can be processed by the Web Audio API.
