Abstract: Systems, methods, and devices of the various embodiments enable dynamic configuration of a number of display regions of interest (ROIs) associated with safety critical content presented on a display, such as a vehicle display. Various embodiments may enable verification of data integrity for ROIs on a display. Various embodiments may enable the selection of different sets of display ROIs from a plurality of independent sets of display ROIs each associated with its own set of stored integrity check values (ICVs). Various embodiments may enable stored ICVs to be used to verify the data integrity of ROIs on a display. Various embodiments may enable the set of display ROIs and the associated ICVs for each display ROI to be changed after a number of frames have been displayed.

Abstract: A digital transcoder system is presented for receiving data bit streams with a first bit rate (R1) and outputting a data bit stream with a second bit rate (R2) which differs from the first bit rate (R1), and in particular is reduced relative thereto. This transcoder system has a decoder device (10) on its input side and a coder device (20) on its output side, the latter consisting of a series circuit of a quantizer (21) for requantizing the data dequantized in the decoder device (10), with a requantization factor (Q2), also with a subsequent VLC coder (22) and an output buffer (23). Establishing the second bit rate (R2) requires that the requantization factor of the quantizer (21) be changed, with reference to macro-blocks, according to the specification of a certain calculational formula.
