Abstract: A computer system for compacting video data. The system acquires a video stream, reduces redundancy through pre-processing, and analyzes the stream to identify patterns and irregularities. It detects spatial or temporal anomalies in the video and produces three outputs: a conditioned video stream based on statistical analysis, an error stream reflecting adjustments made during conditioning, and an anomaly meta-stream containing metadata about detected anomalies. The system communicates with one or more remote systems to synchronize and negotiate a compatible compression codebook, optionally exchanging compact updates that represent differences between local and remote codebooks. The conditioned video stream is then compressed using the agreed codebook.

The prediction samples are obtained by a matrix multiplication of a matrix of coefficients and reference samples of the current block.

The subset of intra prediction modes is derived based on the prediction samples of the current block. The current block is reconstructed based on the prediction samples and the transform set.
