Abstract: Embodiments describe a method, apparatus and system for processing images using block based compression. In one embodiment, a method comprises determining whether two blocks are neighboring blocks, determining whether the two neighboring blocks are both subdivided, if the two blocks are neighboring blocks; performing deblocking filtering on one or more edge pixels of the two neighboring blocks, if it is determined that both of the two neighboring blocks are not subdivided.

Abstract: Apparatus and method for generating multiple descriptions of compressed data is disclosed. In the apparatus and method, transform coefficients are generated from input data and quantized. An energy distribution of the quantized transform coefficients is generated. Based on the energy distribution, the transform coefficients are grouped into layers. By entropy coding different number of layers, multiple descriptions of compressed data are generated.

Abstract: An apparatus for installing a decryption key is initially arranged so that a decryption algorithm received by a control processor is passed via a first interface path to a decryption processor. The algorithm is installed in the decryption processor together with a program decryption key. The apparatus is subsequently arranged so that encrypted working decryption keys received by the control processor are passed on to the decryption processor over the first interface path. The decryption processor decrypts the encrypted keys using the program decryption key. Decryption keys are thus obtained and are transferred via a second interface path to decryptors for use in decrypting encrypted program signals input to the decryptors.

Abstract: Las modalidades describen un metodo, aparato y sistema para procesar imagenes que utilizan bloques basados en compresion. En una modalidad, un metodo comprende determinar si dos bloques son bloques vecinos, determinar si los dos bloques vecinos estan ambos subdivididos, si los dos bloques son bloques vecinos; ejecutar el filtrado de desbloqueo en una o mas pixeles de borde de los dos bloques vecinos, si esta determinado que los dos bloques vecinos no estan subdivididos.
