摘要： The invention relates to a display device using the DLP (Digital Light Processing) technology. This invention is in the field of digital cinema and content protection, where camcorder acquisition followed by immediate illegal distribution creates important revenue losses for content owners. According to the invention, the addressing of the display device is modified in order to introduce an anti-copy processing. The display device comprises modulation means for modulating the color or brightness of video data of video pictures received at a first rate and for outputting at a second rate modulated video data, said second rate being a multiple of the first rate, subfield coding means for coding said modulated video data into subfield data, said subfield data being delivered at the second rate, and addressing means for addressing the array with said subfield data at a third rate. Advantageously, the third rate is not a multiple of the first rate.

摘要： The present invention relates to a method for displaying a video image on a digital display device during a video frame comprising at least two distinct time segments for displaying a grey level. The cells of the device are able to take selectively an on state or an off state. The cells are able moreover to change state several times during a video frame. According to the invention, the cells change state at most once during each time segment of the video frame. The invention makes it possible to attenuate or suppress disturbances related to the temporal integration and to the sequential displaying of the R, G, B components of the video image.

摘要： A particular implementation accesses a disparity value for a particular location in a picture, the disparity value indicating disparity with respect to a particular resolution. The particular implementation modifies the accessed disparity value based on multiple resolutions to produce a modified disparity value. Another implementation accesses a disparity value for a particular location in a picture, the picture having a particular resolution, and the disparity value indicating disparity with respect to another resolution that is different from the particular resolution and that is based on multiple resolutions. A further implementation modifies the accessed disparity value to produce a modified disparity value indicating disparity with respect to the particular resolution.

摘要： The invention discloses a new modulation scheme to prevent illegal copy in movie theaters. None of the existing modulation schemes make the right assumptions to modelize a camcorder device. In such classical schemes, camcorders are always considered as sampling devices without taking into account the effects of shutter speed. The shutter of the camcorder is classically compared to a low-pass filter. As a result, modulation effects can be easily removed by setting up shutter speed to low values (low cutoff frequency). The right mathematical modelization of the shutter effect shows that, in the spectral domain, the behavior of the camcorder is close to a cardinal sine function with a main lobe and sidelobes. Consequently, according to the invention, it is proposed to select a modulation frequency that not only generates visual artifacts once recorded by the camcorder under shutter-free conditions, but that can also generate artifacts despite low shutter speed settings by going through sidelobe of the shutter spectrum.

摘要： The present invention relates to a device for digital display of a video image using time-division modulation. This device is intended to display a video image during a video frame comprising a plurality of consecutive subfields distributed within at least two separate identical time segments. According to the invention, the pixels of the video image change state at most once during each time segment and the video image to be displayed is saved in the image memory in the form of information identifying, for each subfield, the pixels changing state.
