Abstract

fetched live from OpenAlex

Broadcasting multiple scalable video streams over wireless broadband access networks in real time is a challenging problem, because of the limited channel capacity and variable bit rate of the videos. The difficulty is further increased in the presence of receiver buffer size limitations which may introduce buffer overflow possibilities. The Multicast/Broadcast Service feature of mobile WiMAX network is a promising technology for providing wireless video broadcast services. In this article, we describe a substream selection problem which arises when multiple scalable video streams are broadcast based on the Multicast/Broadcast Service feature to a number of buffer size constrained receivers. We first show that the problem is NP-Complete and design a polynomial time approximation algorithm based on convex optimization and dynamic programming techniques. We mathematically prove that the solution obtained through our algorithm is always within a constant factor of the optimal solution. Through simulation we show that under real time requirements our algorithm provides solutions which are within 1 dB of the optimal solutions.

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.
