Abstract:
1. A method for encoding a picture, said method comprising: a) storing a reference picture in a memory; b) taking samples from at least one line of a prediction block, wherein each of the samples comprises a plurality of bits, the plurality of bits comprising most significant bits and least significant bits; c) concatenating the samples; d) replacing the least significant bits of the samples with “don't cares”, thereby generating at least one data word; e) addressing, with the at least one data word, the memory, wherein addressing with the at least one data word results in receiving one or more addresses of memory locations that store the at least one data word that was used for addressing as contents of the one or more memory locations; f) wherein said one or more addresses associated with one or more blocks; g) replacing a portion of the “don't cares” with a portion of the least significant bits of the samples, thereby generating another one or more data words; and h) addressing, with the another one or more data words, the memory, wherein addressing with the another one or more data words results in receiving another one or more addresses of memory locations that store the one or more data word as contents of the one or more memory locations.
