Abstract

fetched live from OpenAlex

This paper presents a joint coding scheme for multi-program video transmission in which the channel capacity is distributed among programs according to their content complexities. The program-dependent bit allocation is achieved by using the same quantization parameter for all the programs at each frame. The joint coding implements a joint rate control which controls the sum of the bit rates for all the programs, instead of each individual bit rate. Computer simulations demonstrate that joint coding is able to maintain a relatively stable quality among the programs as well as within a program, as compared to independent coding.

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.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
