TRANSACTIONAL VIDEO MARKING SYSTEM

摘要

Methods, devices, systems and computer program products facilitate embedding and extraction of transactional watermarks into and from a video content. One such method includes selecting a first number of frames from a video content and performing temporal and a spatial psychovisual analysis on the selected frames. For each selected frame, at least one area for insertion of watermarks is identified. A first and a second watermark symbol is embedded separately in the identified area(s), and the embedded frames are re-encoded to obtain a first and a second alternative data. An inserter manifest is formed that includes the first and the second alternative data to enable insertion of a watermark into the video content by selecting one or the other of the first and second alternative data for insertion into the video content.

主权项

1. A method for facilitating embedding of watermarks into a video content, comprising:
selecting a first number of frames from the video content; performing one or both of a temporal and a spatial psychovisual analysis on the first number of frames; identifying at least one area within the first number of frames for insertion of watermarks; embedding a first watermark symbol in the identified area(s) of the first number of frames; re-encoding the first number of frames subsequent to embedding with the first watermark symbol to obtain first alternative data; embedding a second watermark symbol in the identified area(s) of the first number of frames; re-encoding to the first number of frames subsequent to embedding with the second watermark symbol to obtain a second alternative data; and forming an inserter manifest comprising the first and the second alternative data to enable insertion of a watermark into the video content by selecting one or the other of the first and second alternative data for insertion into the video content.
