Abstract

fetched live from OpenAlex

Overcoming challenges in mobile environments, such as bandwidth constraints, user mobility, and network hand-offs, is crucial for video streaming applications. To address these challenges, we can use multiple network paths to mitigate bandwidth limitations and guarantee end-to-end delay, enhancing the overall quality of experience for the users. This paper presents LiveStream Meta Learning-based Delay Aware Multipath Scheduler (LSMeta-DAMS), a novel learning-based multipath scheduler explicitly designed for live streaming applications. LSMeta-DAMS employs a hybrid meta-reinforcement learning architecture, incorporating both online and offline phases to enhance speed and accuracy for training and decision making. Prioritizing packet scheduling based on frame types and considering the video coding features like group of pictures (GOP), scalable video coding (SVC), and Dynamic Adaptive Streaming over HTTP (MPEG-DASH), LSMeta-DAMS offers a tailored solution for multipath video streaming. Trace-driven emulations highlight its superior performance, demonstrating up to 32% improvement in learning, up to 25% reduction in download time, up to 15% enhancement in video quality assessment, and up to 35% reduction in stalling time compared to the state-of-the-art multipath schedulers. These findings underscore LSMeta-DAMS’s potential to substantially enhance video streaming experiences in highly dynamic network conditions.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
