What the invention does
Warten manages the waiting interval before a live conference. A server establishes a handshake, selects content from event information, obtains the conferencing platform’s authorization, delivers that content through its waiting-room interface, and records engagement. The claim requires delivery within the existing session’s transport and encryption context, without a parallel media session or renegotiated security or transport parameters. Issued claim 8 adds synchronized captions automatically generated from metadata associated with the prerecorded media asset.
Outside content enters on the platform’s authority
Claim 1 requires the content delivery server to establish a handshake with the conferencing system, identify a prerecorded asset using event classification and selection criteria, and obtain an access credential or API token provided by the conferencing system. The asset is displayed through that platform’s waiting-room interface. Its delivery stays within the existing session’s transport and encryption context, without a parallel media session or renegotiated security or transport parameters. A standard waiting-room logo or uploaded clip alone does not describe this full combination.
Selection and measurement
The issued claims include an optional machine-learning classifier using event metadata to classify a meeting, and training that classifier on historical engagement data (claims 3 and 4). Other claims cover playback timing and view duration per participant, metrics such as average view time and completion rate, and updating content-selection criteria in response (claims 10 through 13). These functions could make the waiting interval measurable inventory for a platform or authorized content partner. The patent does not itself establish revenue or a demonstrated return on investment.
Accessibility and Ludwig’s Raven
Issued claim 8 includes synchronized captions generated from metadata associated with the prerecorded asset. Warten’s patent identifies the October 22, 2025 Ludwig’s Raven provisional among its related applications. Ludwig’s separate filing focuses on participant-specific accessibility negotiation and selective delivery of services inside an ongoing session. The Warten claim and Ludwig’s pending scope should be read separately.
A concrete example
Someone waiting for a call receives relevant content through the platform’s existing authorized session. Content delivery does not require a second media session.

Approved explanatory abstract
A system and method for displaying pre-recorded video content in the waiting room of a video call. The invention replaces the blank screen or static image typically shown to users while waiting for the call to be answered with pre-recorded video messages or advertisements chosen by the video call provider. The system comprises a video calling platform, a database for storing pre-recorded content, and a content management system for selecting and displaying the appropriate video based on predefined criteria. When a user enters the waiting room, the selected video content is seamlessly displayed until the call is answered, providing an engaging and informative waiting experience while offering providers an opportunity to communicate with or promote to their audience.
