HD-H16 Dual-Mode LED Media Controller
The Huidu HD-H16 combines media playback, video processing, LED sending, Android applications and local program production. It supports synchronous and asynchronous operation, allowing content to be prepared and played on the terminal for meeting rooms, exhibition halls, broadcast studios, educational spaces and hotel lobbies.
Its 16 Gigabit Ethernet outputs connect to HD receiving cards, while HDMI and optical connections support cascading and display replication. The stated point-to-point LED display capacity is 10 million pixels; 8K decoding describes media processing and is not the LED output resolution.

Local Playback and Meeting-Room Control
The H16 supports multi-window display, independent multi-screen display, local program editing and third-party apps. Playback capability is one 8K stream, four 4K streams, ten 1080P streams, sixteen 720P streams or thirty-two 360P streams.
Bluetooth supports voice control and peripherals such as speakers, keyboards and mice. Wireless screen mirroring supports Windows, iOS, Android and mirroring devices; the product overview lists this as optional, so confirm the required mirroring configuration. HDMI cascading and optical-port replication provide additional options for distributing the display signal.
Check the LED pixel count, receiving-card layout, HDMI sources and fiber equipment before choosing the system. The maximum width and height are separate limits and cannot be combined into one output resolution.

Frequently Asked Questions
Can the HD-H16 work synchronously and asynchronously?
Yes. It supports both modes and combines video processing, media playback and LED sending in one unit.
What is the H16 LED loading capacity?
The stated point-to-point display capacity is 10 million pixels across 16 Gigabit Ethernet outputs. Screen dimensions must also stay within the specified limits.
Does 8K decoding mean the H16 drives an 8K LED screen?
No. Up to 8K at 60 fps describes media decoding. LED output is separately limited by the 10 million-pixel point-to-point display capacity.
What resolution does the HDMI preview output provide?
The HDMI 1.4 preview output is fixed at 1920 × 1080 at 60 Hz. The separate HDMI 2.0 LOOP output serves signal loop-out for video backup.
Can I edit programs without using a separate computer?
Yes. The controller supports local program editing, production and playback, as well as Android applications and third-party apps.
