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. |
