ALEXANDRIA, Va., Feb. 11 -- United States Patent no. 12,549,773, issued on Feb. 10, was assigned to Huawei Technologies Co. Ltd. (Shenzhen, China).
"SPS error avoidance in sub-bitstream extraction" was invented by Ye-Kui Wang (San Diego).
According to the abstract* released by the U.S. Patent & Trademark Office: "A video coding mechanism is disclosed. The mechanism includes encoding a coded layer video sequence (CLVS) for a layer in a bitstream. A sequence parameter set (SPS) referred to by the CLVS is also encoded into the bitstream. The SPS is constrained to have a network abstraction layer (NAL) unit header layer identifier (nuh_layer_id) value equal to a nuh_layer_id value of the CLVS when the layer does not use inter-layer prediction...
