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 translation: 用于对视频帧序列进行编码的视频编解码器将视频帧区域划分成行段数。 视频编码器在一组视频帧中的每个视频帧中选择一组不同的行段，并通过帧内预测对所选择的一组行段进行编码。 结果，帧的所选部分被刷新。 视频编解码器将垂直全局运动矢量GMVy的最大值限制为零，并且视频编解码器基于为运动估计配置的搜索范围的高度来调整所选择的行段集合中的行段数。 结果，视频编解码器可能不指代用于对当前帧的已经刷新的区域进行编码的前一帧中的未刷新部分。

Abstract: Devices, systems and techniques for implementing freedom from interference (FFI) access rules. In an example, a device includes a set of primary components, a set of secondary components, and an interconnected coupled between the two sets of components. Each primary component of the set of primary components has an access identifier, among multiple access attributes, and an access attribute, among multiple access modes. Each secondary component of the set of secondary components is protected by a firewall. Each firewall is configured to specify, for each specific combination of an access identifier and access attribute, whether access to the associated secondary component is permitted and what type of access is permitted.
