Live input, splicing and remote programs
Use HDMI IN when automatic image scaling or synchronous/asynchronous picture-in-picture is required. HDMI LOOP IN supports splicing and cascading. The player can switch between synchronous and asynchronous playback, and its HDMI output can provide a source feed or monitor HDMI-input content.
Programs can be delivered through the communication network or USB interfaces. Dual-band Wi-Fi supports local mobile control; optional 4G/5G connects to XiaoHui Cloud for remote management. External environmental sensors are supported through the two sensor inputs.
