CEC Communication
The MH10 series manages CEC (Consumer Electronics Control) communication between the BrightSign host and any
of the 10 HDMI outputs. The MediaHub employs a separate micro-controller to manage CEC and correct discrepencies
between the protocol of different connected products.
HDMI-ARC
HDMI Audio Return Channels (ARC), controlled by the MH10-HD, support from 2.0 up to 5.1 channel PCM. The number
of PCM channels is decided during programming. Control your presentation via the media microSD card. Content played
via PCM can be played in conjunction with HDMI embedded audio.
Embedded Dolby Atmos and DTS-X Audio
The MH10 series supports embedded audio to play Dolby Atmos and DTS-X, custom tayloring your presentation based
on the capabilities of the device (up to 7.2 channels). The ability to play Dolby and other formats simultaneously is what
sets the MH10-HD apart from other media players. This type of programming is controlled by BrightAuthor programming
and the native media on the microSD card.
Quick Start Instructions
1. Create a new BrightAuthor experience for the HS124 (depending on the module installed in the MediaHub).
2. In BrightAuthor’s presentation properties on the interactive tab, ensure “Port 0” is configured to a baud rate 115200
8-N-1, ASCII, with “CR” for send and receive EOL.
3. Create the presentation. Note that any built-in serial or GPIO port is treated as a serial device, following the applicable
MediaHub serial protocol.
4. Export the presentation to a USB or microSD card and insert it into the MediaHub content port.
5. Connect any peripheral devices, followed by the power supply. EDID should be routed to an HDMI device or to the
internal “SELF” table.
