Player Audio/Video/Image FAQ
BrightSign TechDocs
Do BrightSign players support multiple audio tracks?
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 BrightAuthor:connected) 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 FAQ to make sure your audio format is supported.
Can BrightSign players output component and composite video?
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:
| Pin 1 | Pin 2 | Pin 3 |
|---|
| Pin 1 | Pin 2 | Pin 3 |
|---|---|---|---|
Component RGB | Red | Green | Blue |
Component YPbPr | Pr | Y | Pb |
S-Video | C | Y | - |
CVBS | - | - | CVBS |
In BrightAuthor:connected or BrightAuthor, 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:
PAL-N
PAL-M
PAL-I
PAL-BG
NTSC-M-JPN
NTSC-
How can I check if my video/audio files are compatible with my player?
You can use MediaInfo to check if your files are compatible with a player. To do this:
Download MediaInfo and install it on your system
Launch MediaInfo and go to View > Select Text.
Go to File > Open > File
Browse to your file and click Open
Your output should be similar to this example:

When using H264 encoded video please make sure that you check the Format profile (Format profile: High@L3.2 in the above example) and that it is within the specs described on this page.
Which BrightSign players can be synchronized?
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.
How can I reduce the latency of streaming playback?
The low_latency parameter for RTSP streams, on BOS 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.
