How LineUp's Broadcast Center works — from text alerts and priority levels to live voice relay and scheduled announcements across display screens.
Display screens in service environments are typically used for one purpose: showing queue numbers. But the screens are already deployed, already visible to everyone in the waiting area, and already connected to your network. They're a communication channel that most institutions are using at about 10% of capacity.
The Broadcast Center extends those screens into a real-time announcement system. When something happens that people waiting in your queues need to know about — a service point closing early, a delay in a specific department, a system-wide announcement, or an emergency notice — you can push it to every screen in the building in seconds, without interrupting the queue display.
Every broadcast has a scope, a priority level, and a lifecycle.
Scope determines which screens receive the message. You can broadcast to your entire organization, a specific branch, a single service point, or a specific queue. If you need to tell everyone in your hospital about a power outage, you broadcast at the ORG level. If you need to tell the people waiting specifically in the Paediatric OPD that the doctor is running 20 minutes late, you broadcast to that queue.
Priority determines how the message is displayed. HIGH priority broadcasts — reserved for administrators — override the queue display entirely and display in full-screen mode. NORMAL priority shows as a banner overlay on the queue screen. LOW priority appears as a scrolling ticker. The display system resolves conflicts automatically: if multiple broadcasts are active for the same screen, the highest-priority one is shown.
Not every announcement needs to go out immediately. The Broadcast Center supports scheduled dispatch — you write the message now and set the time it should go live. This is useful for recurring announcements (service hours changes, daily opening notices), for pre-planned events, and for communicating with the morning crowd before staff are fully at their desks.
Scheduled broadcasts go through the same draft → active → stopped lifecycle as immediate ones, and can be cancelled before they fire if plans change.
For urgent situations — an emergency evacuation, a medical alert, a sudden system change — text on a screen may not be enough. The Broadcast Center includes a live voice relay feature that allows authorized administrators to broadcast live audio through any display screen that has a connected speaker.
This works as a push-to-talk relay: the administrator holds the button, speaks, and the audio is streamed in real time to every display screen in the selected scope. When they release the button, the broadcast ends. There is no recording, no delay, and no additional hardware required beyond a speaker connected to the display device.
For common announcements that need to be delivered repeatedly — queue call sounds, service point opening chimes, standard alert tones — the Broadcast Center includes a pre-recorded audio library. Administrators can also upload custom audio clips: branded announcements, language-specific messages, or institution-specific alerts.
Audio plays through the display device's speaker in sync with the visual announcement, giving a multi-sensory alert that's harder to miss in a noisy waiting room.
Frequently used broadcast messages can be saved as templates. Templates are scoped to the organization and visible to all authorized staff. When a service point closes early for the third time this month, the front desk clerk doesn't need to retype the message — they select the template, adjust the scope if needed, and send.
Templates reduce the time to broadcast to under ten seconds for routine situations, and eliminate the risk of typos or inconsistent messaging in high-pressure moments.
