Dynamic profile optimization for video streaming encoding
A recently granted patent (Publication Number: US11979627B2) outlines a method and system for optimizing the encoding of source content, particularly videos, to enhance quality and efficiency. The method involves obtaining the source content, defining resolutions, determining encoding parameters based on target quality values, conducting probe encodings, computing perceptual-weightage using optical modulation transfer functions, and generating encoding profiles for final encoding in a second electronic format. The system includes components such as a communication interface, memory, and processing unit to facilitate these optimization processes.
Furthermore, the patent details the inclusion of encoding ladders in the profiles, which provide information on the number of encodings, video resolutions, and bitrates for each encoding. The optimization process involves scanning allowed ranges of bitrates and resolutions to select the combination that maximizes a Figure of Merit function. Additionally, the system considers target quality values like Structural Similarity Index Metric (SSIM), Peak Signal-To-Noise Ratio (PSNR), Video Multimethod Assessment Fusion (VMAF), and Picture Quality Rating (PQR) to further refine the encoding parameters for the final encoding. Overall, this patent introduces a comprehensive approach to optimizing video encoding processes, ensuring high-quality output while maximizing efficiency and perceptual quality.
