  • Patent number: 11438590
    Abstract: Video data processing methods and apparatuses comprise receiving input data associated with a current chroma block, determine a luma Quantization Parameter (QP) of a collocated luma block, reuse the luma QP of the collocated luma block to derive a chroma QP for the current chroma block, and encode or decode one or more Transform Units (TUs) associated with the current chroma block using the chroma QP. The collocated luma block is a block that covers a collocated sample of one predefined sample of the current chroma block, and an example of the predefined sample is a center sample of the current chroma block. The input video data is partitioned according to two separate Coding Unit (CU) partitioning structures for luma and chroma components when dual tree coding is enabled.

  • Patent number: 11436944
    Abstract: A system for training surgical camera navigation skills is provided. A plurality of two-dimensional targets is printed on an upper surface of a flat sheet of material. The sheet is easily transportable and placed onto a base of a typical box trainer that defines a simulated abdominal cavity between the base and a top. A scope is inserted through a port in the top and the targets are viewed on a live video feed displayed to a trainee on a screen with the targets being otherwise obscured from view by the box trainer. The trainee can move the scope back and forth, roll and angulate the scope about the port in order to view the targets on the sheet at different angles and distances. The trainee is instructed to follow a sequence of targets marked on the sheet and manipulate the scope to align consecutively each target with the edges of the screen in the sequence provided.
