Overview
HD-B8H is a dedicated control system for LED poster screens, integrating a media player, third-party applications and local programme production, enabling programme creation and playback directly on the terminal device. It offers powerful interactive and playback control capabilities, supporting wireless screen mirroring from devices running Windows, iOS, Android and other platforms. It supports the connection of peripheral devices such as central control units, cameras, speakers, sensors and infrared touchscreens. With a wide range of hardware interfaces and flexible playback and control functions, it is widely used in applications such as mobile LED display screens, digital signage and video wall displays.
