Colorlight A4K 4K HDMI Media Player
The Colorlight A4K is a networked media player for commercial digital signage, including retail and advertising displays. It delivers up to 3840 × 2160 at 30 Hz through HDMI and supports H.264, H.265 and VP9 video decoding. Use PlayerMaster to build layouts and publish programs, with ColorlightCloud providing centralized scheduling, monitoring and permission management.
Networked Signage and Local Playback
Connect through Gigabit LAN or dual-band Wi-Fi, or specify the optional 4G configuration. Wi-Fi can also operate as a hotspot for management from a PC, tablet or smartphone. USB flash-drive playback provides a local way to update content.
The HDMI port supplies video to the display. The Ethernet port is a LAN management connection, so system design should account for the display or controller receiving the HDMI signal. Programs can combine video, pictures, text, clocks, web content and weather in adjustable, overlapping windows.
