The proliferation of ultra‑high‑definition (UHD) video streams and the demand for live visual analytics have driven the need for scalable, low‑latency mosaicking solutions. This paper presents , a Java‑based high‑definition (JAVHD) video‑mosaic framework that can ingest, process, and display up to 64 concurrent 4K streams in real time on commodity multi‑core servers. Leveraging a hybrid CPU‑GPU pipeline, a lock‑free tile scheduler, and an adaptive bitrate‑aware compositing algorithm, MEYD‑115 achieves average end‑to‑end latency of 38 ms (± 4 ms) while maintaining ≥ 95 % visual fidelity (PSNR > 42 dB) across a wide range of network conditions. The system is validated on a public dataset of traffic surveillance and on a synthetic benchmark that mimics modern broadcast workflows. Results demonstrate a 3.2× speed‑up over state‑of‑the‑art C++ pipelines and a 45 % reduction in memory footprint thanks to on‑the‑fly tile compression.
