Abstract
The method for encoding and/or decoding video signals, includes the operations of generating at a transmitter side a multiple descriptions vector associated to a pixel values vector of the video signals and decoding at a receiver side available descriptions vector for reconstructing the pixel values vector. The operation of generating a multiple descriptions vector includes the steps of obtaining the pixel values vector by selecting a group of pixels in a picture of the video signal and applying an encoding matrix to the pixel values vector. The decoding operation includes the step of applying a decoding matrix that is in an inverse relationship with the encoding matrix to the available descriptions vector to obtain the pixel values vector.
