Multiple input × multiple output, any input can be switched to any output, each output screen can be different, support cross switching and independent scheduling.
All the input can only be copied into multiple identical screen outputs, and different signal sources cannot be routed to different display terminals.
For the high-frequency pain points of the command center, conference room, exhibition hall, multimedia classroom and other engineering projects, solutions are given one by one.
Multiple signal sources and multiple display terminals want to switch freely and arbitrarily. Ordinary distributors can only copy from the same source and cannot route flexibly.
The field equipment model is complicated, the display resolution is not uniform, and it is easy to appear black edge, unsatisfactory screen and black screen identification.
The equipment in the computer room needs to be compatible with various control methods such as local keys, central control system and network remote control, which cannot be met by a single caliber.
The environment of the computer room is complex, and electrostatic interference is easy to cause equipment crash and signal flash off, which will affect the meeting and scheduling.
The project needs to interface with a third-party central control platform, and the equipment has no open protocol and cannot be integrated and developed for the second time.
Encrypted Blu-ray, set-top box and other HDCP signal sources cannot be decoded and output normally, and the large screen is directly black.
Realize free cross switching of input and output signals, enrich control interfaces, EDID adaptation, HDCP analysis, and adapt to various engineering projects in command centers, conference rooms, and exhibition halls.
QM-HD series of integrated high-definition digital HDMI matrix, engineering-level radio and television program, multi-channel signal arbitrary cross-routing switch.
QM-HD Series One HD Digital HDMI Matrix, adhere to HDMI1.3a protocol, carrying American radio and television grade 6.5GHz switching chipTo achieve any cross-routing switching between multiple HDMI input signals and multiple outputs.
