Abstract: A video codec for encoding a sequence of video frames divides a video frame area into number of row segments. The Video encoder selects a different set of row segments in each video frame in a set of video frames and encodes the selected set of row segments by intra-prediction. As a result, the selected part of the frame is intra-refreshed. The video codec limits the maximum value of the vertical global motion vector GMVy to zero and video codec adjust the number of row segments in the select set of row segments based on the height of the search range configured for the motion estimation. As a result, the video codec may not refer to an un-refreshed portion in the previous frame for encoding an already refreshed area of the current frame.

Abstract: Several methods and systems for masking multimedia data are disclosed. In an embodiment, a method for masking includes performing a prediction for at least one multimedia data block based on a prediction mode of a plurality of prediction modes. The at least one multimedia data block is associated with a region of interest (ROI). A residual multimedia data associated with the at least one multimedia data block is generated based on the prediction. A quantization of the residual multimedia data is performed based on a quantization parameter (QP) value. The QP value is variable such that varying the QP value controls a degree of masking of the ROI.

Abstract: A method of enabling memory access freedom from interference (FFI) rules, comprising: determining a first safety privilege access ID (PrivID) for a first component of a system (e.g., based on Automotive Safety Integrity Level (ASIL) attributes of tasks executed by the first component); determining a first access attribute for a first software task executing on the first component; receiving, at a first firewall component of the system, a request from the first software task to access a first memory region of a second component of the system, wherein the request specifies the first PrivID and the first access attribute; and determining, by the first firewall component, whether to permit the first software task to access the first memory region based on the first PrivID, the first access attribute, and the first memory region.
