Abstract

fetched live from OpenAlex

The paper proposes a new video-on-demand (VOD) broadcasting scheme for variable bit rate (VBR) encoded videos; it is called forward segmentation using equal bandwidth (FSEB). For all practical purposes, FSEB solves the elusive problem of minimizing the server bandwidth for delivering VBR videos with no loss, given an upper bound on the wait time, a uniform upper bound on the channel bandwidths, and the number of channels that a user can access simultaneously. FSEB takes a video as a frame sequence, divides the video into segments, and broadcasts each segment periodically on a separate logical channel. Experimental results with real videos reveal that FSEB requires less server bandwidth and user bandwidth than the only other lossless scheme for VBR videos currently known, which also can limit the number of channels that a user can access simultaneously.

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.
