ALEXANDRIA, Va., Nov. 6 -- United States Patent no. 12,464,135, issued on Nov. 4, was assigned to ATI Technologies ULC (Markham, Canada).

"Filler data-based adaptive lambda for video encoding" was invented by Jin Li (Markham, Canada), Dong Liu (Markham, Canada) and Haibo Liu (Markham, Canada).

According to the abstract* released by the U.S. Patent & Trademark Office: "Techniques for allowing the encoder to use additional data for encoding where the encoder predicts or determines that the encoder will insert filler bits into the encoded video are provided. Specifically, according to these techniques, the encoder uses a modified lambda parameter to calculate rate-distortion cost, which is then used to set encoder settings. In "normal" opera...
