The invention relates to a method of detecting a boundary of a content item in a digital video stream. The method comprises the steps of determining (130) an average bit rate of the video stream over a period of time, and detecting (140) a change of the average bit rate indicating the boundary of the content item. A moving average of the bit rate may be determined. The method can be used for an encrypted digital video stream. The invention also relates to a device for detecting a boundary of a content item in a digital video stream. The invention further relates to a receiver for receiving at least one content item in a digital broadcast video stream, and a video recorder for recording at least one TV program.
