Les normes MPEG : de la compression à la gestion intégrée des contenus multimédias
Why this work is in the frame
A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.

Abstract
Le Motion Picture Experts Group est un organisme chargé de développer des normes internationales sur les fichiers informatiques multimédias. Les normes MPEG-1 et MPEG-2 édictent des modes de compression de fichiers visuels et sonores permettant le transfert rapide en réseau et facilitant le stockage sur disque. MPEG-4 concerne également la compression, mais s’applique à la diffusion en temps réel (« streaming »). MPEG-7 propose un système de description des documents basé sur des métadonnées permettant des recherches très sophistiquées. Finalement, MPEG-21 offrira un cadre d’application pour une gestion intégrée des ressources multimédias (création, distribution, gestion des droits d’auteur, mode de paiement, etc.).
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.
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
