Abstract

An apparatus for temporally shifting video data within a video signal is provided with a video data source for providing a video signal and a signal splitter for generating a first video data stream and a second video data stream, the first video data stream comprising video data in excess of a threshold. The apparatus includes means for temporally shifting the excess video data in the first video data stream relative to the second video data stream and means for recombining the first video data stream with the second video data stream after the first video data stream has been temporally shifted relative to the second video data stream. The means for temporally shifting the excess video data in the first video data stream relative to the second video data stream may include a first delay buffer for delaying the first video data stream by an adjustable time period and a second delay buffer for delaying the second video data stream by a fixed time period.
