Description

Technical Field

[0001] This utility model relates to the field of signal distribution and conversion technology, and in particular to a multi-channel video information distribution and conversion device based on an HDMI interface. Background Technology

[0002] HDMI (High Definition Multimedia Interface) is the first digital interface to support the transmission of uncompressed, fully digital high-definition, multi-channel audio and intelligent format control command data over a single cable. HDMI can provide data transfer bandwidth of up to 5Gbps, transmitting uncompressed audio and high-resolution video signals without requiring digital-to-analog or analog-to-digital conversion before transmission, ensuring the highest quality audio and video signal delivery.

[0003] However, traditional HDMI devices typically only support one-to-one HDMI output, which cannot meet users' needs for simultaneous HDMI output and USB VIDEO output, such as outputting one HDMI signal to a local display and inputting the HDMI video signal to another computer for recording, editing, or live streaming.
