Video waveform peak indicator
A waveform monitor device, or media analysis device, to monitor a video signal. The waveform monitor device may include an input to receive the video signal, the video signal having a plurality of frames, a memory to store the received video signal, a processor coupled to the memory, and a display. The processor separates the video signal into at least two component signals, for at least one component signal, determines a peak value of the at least one component signal for at least one frame of the plurality of frames, generates a marker at the peak value, determines if the peak value violates a predetermined threshold, and generates an alert when the peak value violates the predetermined threshold. The at least one component signal, the marker at the peak value on the component signal and the alert when the peak value violates the predetermined threshold are displayed on the display to allow a user to quickly determine if a video signal is within a required threshold.
