Abstract: A Delay-Tolerant Network Architecture for Real-Time Video Relay in Deep Space Uplinks is disclosed, providing a comprehensive hardware-integrated system that enables reliable, continuous transmission of video data from deep-space platforms to Earth-based ground stations despite the severe constraints of extreme signal propagation delays, intermittent communication link availability, limited bandwidth, and high bit-error rates characteristic of interplanetary communication environments. The architecture comprises a sequential functional pipeline including a space-grade Video Source Unit for image acquisition, a Video Processing and Encoding Unit applying adaptive H.265/HEVC compression, a Delay-Tolerant Networking Control Unit implementing Bundle Protocol store-and-forward operations with custody transfer semantics, a radiation-tolerant hierarchical Onboard Data Storage Buffer for video data retention during communication blackouts, a Forward Error Correction Module applying adaptive lowdensity parity-check coding, a Deep-Space RF Transceiver Module and High-Gain Antenna Assembly for interplanetary signal transmission, an optional Space Relay Communication Unit for multi-hop forwarding scenarios, and an Earth Ground Station Receiver with Bundle Protocol reassembly and H.265/HEVC decoding capabilities. Signal propagation delay T = D/c governs communication timing parameters, while the link budget equation Pr = Pt + Gt + Gr - Lp ensures adequate received signal margin across the operational communication range. The architecture operates autonomously during communication blackout periods, preserving all generated video data in onboard storage and forwarding it opportunistically during available contact windows, thereby ensuring end-to- end video integrity without requiring continuous connectivity between the deep-space source and the Earth receiving system. The invention addresses a critical gap in existing deep-space communication capabilities by providing for the first time a complete, scalable, and modular solution for disruption-resilient real-time video relay applicable to planetary exploration, crewed interplanetary missions, deep-space scientific probes, and commercial space operations requiring continuous visual situational awareness over interplanetary distances.
