Title: Method for assessing synchronization between a communication device and a remote time server
Inventor: LIONEL TOCZE
IPC: H04W56/00
Filed: 2020-06-09
Abstract: Assessing stability of synchronisation between the clocks of a communication device and a time server by synchronising the clocks according to a protocol, receiving time offset between the device and server, receiving path delay information between the device and server and assessing the synchronisation between the device and server according to the offset and delay. Synchronisation may be assessed by checking if the offset and delay values are within certain ranges. The receipt of offset and delay information and assessment may be iteratively performed, and synchronisation may be determined to be stable if following N iterations, the offset and delays are within the first and second ranges. The delay range may be proportional to a previously received delay value. The time synchronisation protocol may conform to Precision Time Protocol (PTP) standard. If the synchronisation is stable, then iterations may be stopped. If the number of iterations exceeds a maximum without being stable, new offset information is received, and synchronisation is assessed without accounting for path delay. If the synchronisation is unstable a control signal is sent to an image capture device to use timings independent of the communication device clock. Upon determining an unstable synchronisation, the communication device may change to a different time server.

Title: Discrete dither
Inventor: PETER GRAHAM CRAVEN
IPC: H03M7/30
Filed: 2018-12-18
Abstract: A bit is buried in a pair of data samples by identifying two possible 2-tuples (pairs) of output values, where each pair conveys the same bit of data, and pseudo-randomly choosing one of the two possible pairs with equal probability (50%). The two possible 2-tuples may differ by exactly one step in both dimensions. The 2-tuples of output values can be thought of as lying on a grid, and in an embodiment, a 1 bit can be conveyed using either of the grid locations shown on the left, and a 0 bit can be conveyed using either of the grid locations shown on the right. Using these locations would remove noise modulation that would otherwise arise due to some least-significant bit pairs already conveying the desired bit and other pairs needing to be altered. The output signals would differ from the original signals by half a quantisation step, on average.
