Abstract
Modern mobile devices, despite their small sizes, can run many multimedia applications that were only possible to stationary workstations. Mobile devices, however, have quite heterogeneous resources, which poses a challenge to mobile TV broadcast networks. We study the problem of broadcasting multi-layer video streams to mobile devices with heterogeneous resources. We propose broadcast schemes that allow each mobile device to selectively receive a few (or all) layers of the complete video streams, and achieve proportional energy saving. We also propose a broadcast scheme that achieves low channel switching delay, which is important to user experience. We analytically analyze the performance of the proposed schemes. Most importantly, we have implemented them in a real mobile TV testbed. We conduct extensive experiments to show the practicality and efficiency of the proposed schemes. The experimental results show that channel switching delays less than 200 msec and energy saving between 75% and 95% are possible under typical system parameters of mobile TV networks.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
