There is provided a method for detecting signal conditions for Motion Picture Experts Group (MPEG) streams. Alternate-mode flags and valid frames within the MPEG streams are detected within a pre-defined search window. An indication that a valid signal is detected is output, when an alternate-mode flag and at least one valid frame are both detected within a same one of the predefined search window.
