US Patent Issued to InterDigital VC Holdings on June 23 for "Symmetric motion vector difference coding" (New Jersey, California Inventors)

ALEXANDRIA, Va., July 15 -- United States Patent no. 12,666,035, issued on June 23, was assigned to InterDigital VC Holdings Inc. (Wilmington, Del.).

"Symmetric motion vector difference coding" was invented by Jiancong Luo (Skillman, N.J.), Xiaoyu Xiu (San Diego), Yuwen He (San Diego) and Hua Yang (Plainsboro, N.J.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Bi-directional optical flow (BDOF) may be bypassed, for a current coding block, based on whether symmetric motion vector difference (SMVD) is used in motion vector coding for the current coding block. A coding device (e.g., an encoder or a decoder) may determine whether to bypass BDOF for the current coding block based at least in part on an SMVD indi...
