‌Client Advertising Display Features:‌

00001. ‌Network Updates:‌ Updates content via wired/Wi-Fi/4G networks. The device checks for new download tasks upon connecting to the server. If updates exist, playback pauses to download new files, then resumes automatically.

00004. ‌Scrolling Subtitles:‌ Supports real-time scrolling ticker messages for instant updates.

00005. ‌Group Control:‌ Manages multiple terminals simultaneously, each playing unique content.

00006. ‌Third-party Integration:‌ Compatible with station announcement systems (customizable protocols for RS485/CAN/RS232 signals).
