| 摘要 | Methods and apparatus to monitor audio/visual content from various sources are disclosed. Example methods disclosed herein to monitor a media presentation include generating a plurality of interpixel differences associated with a plurality of video samples of a video signal corresponding to a video frame of the media presentation. Such example methods also include processing the plurality of interpixel differences to determine whether the video frame exhibits macroblocking. Such example methods further include eliminating a first source from a plurality of possible sources of the media presentation when the video frame exhibits macroblocking. | ||
