User-selected media content blocking
Tue, 18 Jun 2013 08:00:00 EDT
|
Presented herein is a method of blocking user-selected media content, such as, for example, audio and/or video content. In the method, at least one media content stream is presented to a user, wherein the at least one media content stream includes multiple showings of an identifiable contiguous segment of media content. One example of such a segment may be a commercial or advertisement. While presenting a current showing of the segment of media content to the user, a command is received from a user to block the segment of media content from presentation to the user. In response to receiving the command, information identifying the segment of media content is generated. The at least one media content stream is analyzed using the information to detect subsequent showings of the segment of media content. Presentation of at least one of the subsequent showings of the segment of media content is prevented when detected in the at least one media content stream.
