Abstract: A system and method is provided for performing high dynamic range digital double sampling. More particularly, a CMOS image sensor is provided that includes a pixel array with each pixel sampling both dark and bright values for digital double sampling. After the sampled signals are digitized, a mean dark value is determined and each dark value is further fed to a lookup table that generates an output value taking into account whether the pixel has been saturated. In over exposed conditions, the lookup table will generate a negative value output to eliminate image artifacts. All three values are fed to adder logic circuit that subtracts the mean dark value and the lookup table output from the bright value. This resulting output is fed to a video viewer.

Abstract: The present aspects relate to techniques of timing synchronization of audio and video (AV) data in a network. In particular, the techniques for a AV master to distribute AV data encoded with one or more time markers to a plurality of processing nodes. The one or more time markers may be indexed to a precision time protocol (PTP) time stamp used as a time reference. In one technique, the nodes extract the time markers to determine an offset value that is applied to a PLL to synchronize AV data packets at a distribution node or a processing node. In another technique the distribution node or the processing node determines the worst case path, which corresponds to a system offset value. The distribution node then reports the system offset value to the AV master, which in turn adjusts the phase based on the report.
