Reserved Bit Prediction for Pipelined Video Slice Control

The patent applies preliminary action by estimating the bit consumption of coding units before they are actually encoded. The system calculates predicted bit values for coding units in advance using a prediction model, allowing slice size control to be performed without waiting for the actual encoding to complete. This resolves the timing issue where coding units were not properly counted due to pipeline delays.

The patent changes the parameter of slice size by dynamically adjusting it based on predicted bit consumption. By modifying the slice size parameter adaptively, the system achieves a balance between minimizing packet count and maintaining error recovery capability. This allows slice headers to be inserted at optimal positions that prevent decoder disruption while keeping the number of packets low.

The patent implements feedback by using the prediction model to continuously monitor and adjust slice size based on actual bit consumption patterns. The system learns from encoding results and refines its predictions, allowing it to determine the optimal frequency for inserting slice headers. This feedback mechanism prevents both excessive header insertion (which reduces efficiency) and insufficient header insertion (which harms error recovery).
