This utility model discloses a high-definition video expansion dock device and its integrated
system. The device includes a main control module, a protocol conversion module, a
power management module, a
video processing module, a
dynamic bandwidth allocation unit, multiple
video output interfaces, and a
peripheral expansion unit. The main control module receives input video signals and performs splitting, compression, and protocol
parsing; the protocol conversion module manages
interface protocol switching, device detection, and power supply negotiation; the
power management module converts the input
voltage into multi-level
system voltages and provides reverse charging functionality; the
video processing module splits the input video
signal into multiple independent video streams and reduces bandwidth; the
dynamic bandwidth allocation unit dynamically adjusts the resolution or
refresh rate of the video streams; and the
peripheral expansion unit connects to low-speed peripherals through
independent data channels. This device supports three-channel 4K@60Hz simultaneous output, features
high energy efficiency, intelligent
bandwidth management, and good compatibility, and is suitable for multi-screen
collaboration, industrial control, and high-resolution display applications.
