摘要：
Methods and apparatus for detecting on-screen media sources are disclosed. An example method includes monitoring a region of interest of a video signal for a first image, comparing the first image to a stored image, and confirming the media device change when the stored image differs from the first image and is associated with a secondary criterion.
