Abstract

fetched live from OpenAlex

The diversity of devices in both wired and wireless networks via which multimedia contents are desired to be accessed and interacted with has grown significantly. Applications like video conferencing, surveillance and chatting is challenged by this diversity which requires live adaptation to meet user requirements and device specifications. In this paper, we present an architecture for temporal adaptation of ITU-T H.264 video conforming to ISO/IEC MPEG-21 DIA for live video stream along with the adaptation module implementation detail. Adaptation is performed on demand directly from the live bitstream and its generic bitstream syntax description (gBSD) avoiding conventional approaches seen in traditional transcoders. As a result, any MPEG-21 compliant host can adapt the stream without requiring the video codec. A prototype, based on the proposed architecture, and experimental evaluations of the system and its performance supporting the architecture are also presented

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.
