Abstract

fetched live from OpenAlex

H.264 also known as MPEG-4 part 10 or JVT, is a new video coding standard that is extremely efficient and is poised to appear in the next generation of HD-DVD players and recorders. This paper presents one of the first hardware architectures of the transform and quantization blocks, which are incorporated into a software/hardware system implemented on a Virtex II Pro FPGA. This implementation focuses on eliminating drift effects, multiply free and low gain transform, and reducing memory bandwidth. A large system on a programmable chip was developed. It uses a Power PC (PPC) to run a software program to optionally perform DCT and quantization in both the software and hardware. This paper presents DCT and quantization blocks that can process about 1500 Mpixel/s, and a system that can process about 0.8 Mpixel/s.

Full frame distilled prediction

Teacher imitation

Not 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.
