Abstract
The delivery of High Definition Television (HDTV) over IP networks, namely the HD IPTV, has emerged as one of the major distribution and access techniques for broadband multimedia services. IPTV adopts H.264/AVC as its coding standard due to its high video compression efficiency as well as powerful error resilience features. This paper presents studies on some of these features applied to HD IPTV applications. A test system is deployed to simulate the delivery of HD video over a DSL based IPTV network. Effects of error resilience of slicing and Instantaneous Decoding Refreshing (IDR) features on video quality are examined in both channel non-impaired and channel impaired with burst noise circumstances. Based on the acquired results, optimal slice size was obtained for HD video transmission over an impaired channel. The quality of experience related to the IDR interval in combating error propagation was also characterized.

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
