1. A computer assisted apparatus for transmitting multimedia, said computer comprising a processor, said apparatus comprising: an image compression unit for compressing, via the processor, an image portion of a multimedia data frame; an audio compression unit for compressing an audio portion of the multimedia frame; a bit rate manager in communication with said image compression unit, and said audio compression unit for controlling frame flow; and a merger unit in communication with each of said image compression unit and said audio compression unit for merging a compressed image portion and a compressed audio portion into a single compressed multimedia frame, wherein the image compression unit utilizes R-Tree-based multidimensional hierarchical categorization trees to compress said image portion, and wherein the R-Tree-based multidimensional hierarchical categorization trees examine pixel blocks that are structurally similar to a reference block, and organize pixel blocks in a hierarchical manner.
