ALEXANDRIA, Va., Sept. 8 -- United States Patent no. 12,732,613, issued on Sept. 8, was assigned to Agora Lab Inc. (Santa Clara, Calif.).

"Systems and methods for intelligent quantization" was invented by Wei Dai (Shanghai).

According to the abstract* released by the U.S. Patent & Trademark Office: "Systems and methods for intelligent quantization for video compression are provided. In some embodiments, the methods and systems estimate a rate-distortion function is for video coding. An offset to a reconstruction process is applied, where the offset is determined based upon a frequency dependent variable and a quantization step size. The offset is then derived by transmitting the frequency dependent variable to a decoder. Additionally, a t...
