Abstract
TV delivery over IP networks (i.e. IPTV) has emerged as one of the major distribution and access techniques for broadband multimedia services. IPTV adopts H.264 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 the H.264/AVC error resilience features applied to IPTV applications, namely, high definition (i.e., HD IPTV) and wireless/handheld extension. Test systems are deployed to simulate: (1) The delivery of lower resolution TV programs over wireless channels; (2) The delivery of HD video over an xDSL based IPTV network. Flexible Macroblock Ordering (FMO) slice grouping is assessed in handheld IPTV applications. Optimal slice size is obtained for HD video transmission over impaired channels. The quality of experience related to the Instantaneous Decoding Refreshing (IDR) interval is characterized for HD IPTV.

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
