What the invention does
Ludwig’s Raven receives participant accessibility requirements, checks them, and arranges selective delivery of services such as captions, translation, enhanced audio or sign-language interpretation. Its approved explanatory abstract describes adjusting those services as participants and conditions change while preserving the session identifier and existing signaling and media security context.
A concrete example
One participant needs translated captions and another needs sign-language interpretation. Each receives the authorized service, while other participants continue receiving the primary media.
AI in the filed record
The October 22, 2025 provisional expressly discloses AI-generated sign-language services inside the continuing session. It describes provisioning GPU or other compute resources for AI processing, initializing models, performing AI model inference, and generating synchronized accessibility output.
The same filing also places service activation behind a policy gate and records enablement, disablement, pipeline start/stop, participant identifiers and policy decisions against the same live-session timeline. This is a concrete AI embodiment inside the governed session; it is not a general claim to autonomous AI agents.
Read the published evidence
The approved explanatory abstract below is separate from the claim and abstract originally filed with the provisional. It does not replace those historical source documents.
Approved explanatory abstract
A communication system performs participant-specific negotiation and selective distribution of accessibility services within an ongoing real-time communication session. A session controller receives participant-associated descriptors identifying accessibility requirements or capabilities, validates each descriptor against session policy and available service capability, and conditionally activates a corresponding accessibility processing pipeline only when an authorized participant requires it. Resulting captions, translation, audio description, enhanced audio, sign-language interpretation, or avatar video are routed only to authorized participants while other participants continue receiving primary media. Participant joins, departures, preference changes, policy changes, or service faults trigger re-evaluation, modification, substitution, or teardown of the pipeline and routing state while the session identifier is preserved and the originally negotiated signaling and media security context is reused, without a new SIP Call-ID or WebRTC PeerConnection. Decisions and state transitions are recorded against the same session timeline.
