Abstract
H.264/AVC is the newest international video coding standard. The standard uses a new DCT-like integer transform (Int-DCT) which is an integer orthogonal approximation to the classical DCT. The objective of using integer coefficients is to provide a completely reversible transform and also reduce the implementation complexity. The main disadvantage is that it increases the quantizer complexity and, consequently, the hardware costs. In this paper we present a new error-free encoding, based on algebraic integers, for a classical DCT and its hardware implementation. This can be used as an alternative transform for H.264 encoders, which results in a simple, parallel, and multiplication-free architecture, and also minimizes the complexity of the quantizer and the dynamic range of the computations. We propose an initial FPGA implementation where the system can process around 1650 Mpixel/sec, and satisfies all real time constraints for digital multimedia applications

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
