Patent ID: 10734004

Abstract:
Systems, methods, apparatus, and articles of manufacture to improve timestamp transition resolution of watermarks are disclosed. An example system includes a watermark detector to detect watermarks in media and a decoder to decode timestamps from respective ones of the watermarks. The example system also includes a timestamp transition resolution enhancer to: (a) estimate, based on the timestamps, a coarse transition window between two time periods of the media; (b) map a prior transition window estimate to the estimate of (a); (c) determine a fine transition window estimate based on an overlap between the estimate of (a) and (b); (d) compare the fine transition window estimate of (c) to a threshold; (e) repeat (a) through (d) for successive time periods of the media using the fine transition window estimate of (c) as the prior transition window estimate of (b) until the fine transition window estimate of (c) satisfies the threshold; and (f) set the fine transition window estimate to be an established moment of transition between time periods of the media when the estimate of (c) satisfies the threshold.
