The disclosure describes a method of embedding a digital watermark into a video signal using a time based perceptual mask such that the digital watermark is substantially imperceptible in the video signal. A digital watermark embedder computes a time based perceptual mask comprising gain values corresponding to locations within a frame. The gain value for a location in the frame is changed as a function of the change in one or more pixel values at the location over time. The embedder uses the gain values of the time based perceptual mask to control embedding of corresponding elements of a digital watermark signal such that the perceptibility of the elements of the digital watermark signal is reduced in time varying locations of the video signal.

A system is disclosed where the well-known psycho-acoustic masking effect, i.e. frequency and / or temporal masking is applied to reduce the human perception of a noise signal. An input signal, such as music or another entertainment signal, is adjusted based on the intensity of the auditory noise by applying existing knowledge about the properties of the human auditory perception and is provided to the human user as a masking sound signal, so that the masking sound elevates the human auditory perception threshold for at least some of the noise signal, whereby the user's perception of that part of the noise signal is reduced or eliminated. The masking sound may be combined with active noise control where a sound in anti-phase with the noise signal is provided for further reduction of the human perception of the noise signal.

An organic light emitting display device, which may maximize aperture ratio of a pixel while also reducing the perception of a dark spot when a sub-pixel is partially short-circuited. The organic light emitting display device includes a plurality of pixels having sub-pixels. Some of the sub-pixels may have a thin organic emission layer which makes them likely to short-circuit across the thin organic emission layer. These sub-pixels are formed as divided sub-pixels including at least two drive transistors and operate such that even if one part of the divided sub-pixel has a short circuit, the other part will continue to emit light. Accordingly, while luminance is reduced as a result of short circuiting, a completely dark spot will not appear in the place of the pixel including the short circuit.
