Synchronous and asynchronous playback explained
Asynchronous mode: play stored programs
Asynchronous playback uses content stored on the player. This is a practical option for screens that repeat advertising or information programs. The HD-A8 provides onboard storage and supports USB content updates, so the display does not need a continuous live video feed for stored-content playback.
Synchronous mode: display an external source
Synchronous playback uses a connected HDMI or DP video source. Choose this workflow when the LED screen needs to show content from an external device. Confirm the source signal, screen resolution and receiving-card configuration together before installation.
Content updates and remote management
Dual-band Wi-Fi supports wireless control through a mobile app. The player also supports local-network or Internet cluster management for updating connected screens. If a site requires a cellular connection, specify the optional network module when requesting your configuration.
V2.3 lists voice control and includes a Bluetooth remote in its packing list. Wireless phone/tablet casting and 4G/5G networking are optional. Confirm the supplied accessories, firmware and enabled functions for the intended workflow.
