Abstract

fetched live from OpenAlex

Multimedia distribution over the Internet is becoming increasingly popular. A novel framework for Internet video streaming is proposed. For video compression, our previously developed three-dimensional significance-linked connected component analysis (3D-SLCCA) codec is applied. 3D-SLCCA provides high coding efficiency, multiresolution video representation, transmission error resilience, and low computational complexity. For audio coding, the GSM standard is used. For error control, retransmission and error concealment are jointly applied. Multiresolution-multicast transmission is implemented by assigning different multicast group addresses to different video layers. Thus each receiver subscribes to the maximum number of layers that both its hardware resource and network capability can handle. By using a hierarchically structured multicast tree, each node is responsible for caching packets, collecting NACK packets, and sending repair packets. This not only significantly reduces the latency, but also efficiently solves the "ACK implosion" problem. As opposed to data transmission, reliable multicast is not required by the network infrastructure. Based on timing constraint and importance of lost packets, each receiver decides whether to request retransmission or apply error concealment. Finally, synchronization is accomplished by using the timestamp mechanism of RTP.

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.
