摘要： A method and system for embedding an authentication signature in an audio-visual signal such that only a part of an entire frame of the audio-visual signal is stored in a memory while the signature bits are calculated and the watermark is embedded. A signature is formed based on a first portion of said audio-visual signal, whereby said first portion is a pattern of horizontal lines of said audio-visual signal and has fewer lines than the number of lines of the entire audio-visual signal. Thereafter the signature generated is embedded in said audio-visual signal in the first portion and/or in another portion of the frame to be authenticated, whereby the other portion also is a pattern of horizontal lines. Thus only memory for some lines instead for all lines of the audio-visual signal is needed. In the case of an interlaced audio-visual signal, the first portion is preferably the first field of a frame of said audio-visual signal and the second portion is the second field of said audio-visual signal. In the case of a non-interlaced audio-visual signal, slices of said lines are preferably used for said portions.

摘要： RGB to NTSC/PAL encoders—as an example—commonly convert red, green and blue colour component signals (RGB) into their corresponding luminance (luma) and chrominance (chroma) signals in the respective standards in order to generate a composite video signal which can be used in connection with television sets and the like. Thereby, roughly spoken, the luminance signal represents the monochrome or black-and-white portion of the composite video signal and the chrominance signal represents the colour portion of the composite video signal. An apparatus 1 for limiting the vector length of colour vectors U, V carrying the chroma information for a composite video signal, is disclosed, which comprises an input module 2 being operable to receive two colour signal values U, V each representing one of the colour vectors, a calculating module 7, 8, 9, 10 being operable to calculate a vector length representative of a chroma vector derived by vector addition of the two colour vectors U, V, a comparator module 13 being operable to compare the vector length representative with a limiting value, a limiting module 11, 14 being operable to limit the vector lengths of the two colour vectors and/or the two colour signal values U, V under the condition that the vector length representative exceeds the limiting value by multiplying the vector lengths and/or the values with the reciprocal value of the vector length of the chroma vector.

摘要： A multi-picture in picture system in which each camera is coupled in a daisy chain adds its part of the complete picture on a CVBS-line. The television/monitor doesn't have to prepare the complete picture because each camera does it. Furthermore, no problems with locking occur because each camera adds its picture at the “place” where it is also locked.

摘要： In the technical field of video cameras gamma correction is an often used technique to compensate the non-linear effects of the CRT (cathode ray tube), in order to enhance visibility in images to be displayed. Gamma correction is—by way of example—expressed by the gamma function: A process for enhancing detail visibility in an input image comprising a step of applying a first transfer function (11) to the input image, thereby generating an intermediate image; a step of performing a statistical measurement (12), Mmt (2) on the intermediate image; a step of applying a second transfer function (14) to the intermediate image, thereby generating an output image; a step of performing a statistical measurement (15), Mmt (3) on the output image, a step of determining gain parameters gg, gk for the first and the second transfer function (11, 14) on basis of the statistical measurement results (8, 12, 15), Mmt (1), Mmt (2), Mmt (3) is proposed.
