Hybrid Automatic Content Recognition and Watermarking

摘要

A reference fingerprint is generated from essence of each corresponding time segment of a media program. A watermark request with the reference fingerprint is sent to a media content identification server. An individual watermark value for the corresponding time segment of the media program is received from the media content identification server in a response to the watermark request. A watermarked version of the media program is generated to comprise one or more individual watermark values embedded in essence of the media program that include the individual watermark value for the corresponding time segment of the media program. Watermark data rates and update rates can be chosen dynamically based on underlying media content. Existing watermark values for media content in a content identification data repository may be updated dynamically when new media content is added.

1. A computer-implemented method comprising:
receiving a user specification for a specific portion of a media program as a time segment in a plurality of time segments in the media program, wherein each time segment in the plurality of time segments in the media program is to be uniquely identified by a fingerprint and watermark combination; generating a reference fingerprint from essence of each time segment of the media program in the plurality of time segments of the media program; sending, to a media content identification server, a watermark request with the reference fingerprint; receiving, from the media content identification server in a response to the watermark request, an individual watermark value for the each time segment of the media program; generating a watermarked version of the media program, the watermarked version of the media program comprising one or more individual watermark values embedded in essence of the media program, the one or more individual watermark values including the individual watermark value for the each time segment of the media program; wherein the method is performed by one or more computing devices.
