20110134995 | VIDEO CODING WITH CODING OF THE LOCATIONS OF SIGNIFICANT COEFFICIENTS IN A BLOCK OF COEFFICIENTS - In known image compression, following quantisation, a very sparse distribution of significant (i.e. non-zero) amplitude coefficients of the transformed image signal may be obtained while most quantised coefficients are zeros. A costly task for a transform-based image compression in terms of resulting overall data rate is to record the locations of such significant coefficients within the coding blocks. In quartation processing, a ‘significant square’ (containing at least one non-zero amplitude coefficient in the coefficient block) is recursively divided into four smaller squares until single significant coefficients are reached, and the significance statuses of all generated squares are encoded. However, for some distribution patterns encoding the x-y-coordinates of the significant coefficients as binary numbers will lead to less coding cost. According to the invention, at least four different pattern determination or encoding modes are checked, and the encoding side selects the least costly one of these modes and transfers the corresponding mode information to the decoding side for corresponding decoding. | 2011-06-09 |

20110135089 | IMAGE ENCRYPTING/DECRYPTING SYSTEM AND METHOD - The present invention relates to an image encrypting/decrypting system and method devised in such a way that: a transmitter and a receiver for transmitting and receiving moving images share a seed for encrypting and decrypting the moving images; the transmitter transmits moving images after encrypting the moving images by dividing them into segment units and mixing the time sequencing of the images in each of the segments in accordance with a random number generated by means of the seed; and the receiver decrypts the moving images which it receives, by sorting them in segment units and then restoring the time sequencing of the images in each of the segments in accordance with the random number generated by means of the seed. The present invention makes it possible to effectively implement the function of encrypting after having carried out transcoding even in cases involving an alteration to the frame or an increase in resolution in an encrypted moving image, and also makes it possible to resolve the problem of having to encrypt/decrypt before/after carrying out transcoding in cases where a compressed moving image is being encrypted. | 2011-06-09 |
