Abstract
In contrast to Europe’s digital switchovers coordinated around the ITU Region 1 deadline of 2015, the rest of the world is making the transition over a much more protracted period. In ITU Regions 2 and 3 the advanced economies of Canada, Japan, South Korea, Taiwan, Australia and New Zealand have completed, or will complete, their transitions in parallel with the Region 1 timetable. China and India, for different reasons, have both concentrated in the first instance on digitising their cable TV infrastructure. For countries which are still at a relatively early stage in the process a major issue has been the choice of technical standards, with competition between the American ATSC, the European DVB, the Japanese ISDB (Integrated Services Digital Broadcasting), the Chinese DTMB (Digital Terrestrial Multi-media Broadcasting) and a Brazilian variant of Japanese technology, SBTVD-T. A pattern of regional groupings has emerged: South-East Asia, Australasia and Africa have broadly adopted the DVB standard while South American countries have coalesced around Brazil’s SBTVD-T. Central America and the Caribbean countries are being tugged in different directions.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
