  • Use of steganographically-encoded data as basis to control dynamic content modification as to at least one modifiable-content segment identified based on fingerprint analysis
    Patent number: 11962846
    Abstract: The disclosure provides for use of steganographically-encoded data as a basis to control content modification. A server could determine through a fingerprint comparison that a portion of media content on a channel being rendered by a content presentation device matches at least one modifiable-content segment, such as at least one replaceable ad. The server could then use watermark data encoded in the media content of the channel as a basis to determine an actual identity of a modifiable-content segment present on the channel, so as to then control content modification.
    Type: Grant
    Filed: December 14, 2021
    Date of Patent: April 16, 2024
    Assignee: ROKU, INC.
