Adaptive GOP Length Determination for HEVC Video Encoding

The patent transforms the static fixed GOP length into a dynamic adaptive GOP length that changes according to video content characteristics. The system dynamically adjusts GOP length based on motion complexity, texture complexity, and other video frame features, allowing the encoding system to adapt to different scenarios and maintain high encoding quality while managing complexity through automated analysis.

The patent changes the GOP length parameter from a fixed value to a variable that is determined by analyzing video frame characteristics. By computing complexity metrics and using these as inputs to determine GOP length, the system optimizes the parameter based on actual video content rather than using a predetermined fixed value, thereby improving encoding quality in fluctuating scenarios.

The patent performs preliminary analysis of video frame characteristics before encoding to determine the appropriate GOP length. By pre-computing motion complexity, texture complexity, and other features, and using these to select GOP length before the actual encoding process, the system achieves adaptability to different video scenarios while maintaining encoding stability through structured preprocessing.

The patent introduces an intermediary analysis layer that sits between the video input and the encoding process. This intermediary computes video frame characteristics and uses them to determine GOP length, acting as a mediator that translates raw video content into encoding parameters. This approach enhances adaptability by analyzing actual video content while managing complexity through a structured intermediate processing stage.
