A system and method for organizing and processing signals from multiple sources subdivides the source data into a plurality of processing paths. The data is stored in a buffer on each path in packages having fixed length words. A buffer controller controls drawing of the packages to a multiplexer and prevents underflow and overflow in each of the buffers. The multiplexer combines the data packages from each path and from each source according to a generation time priority. Each package includes a heading indicating its source and destination paths. The packages are transmitted along a transmission line, and the data is demultiplexed and outputted according to the headings.

Method and system for transmitting packages of data

A redundancy reduction algorithm, such as hybrid DCT, is applied to a video signal and is subsequently encoded by pixel blocks, and motion vectors are generated for each image block. At least one global motion vector is then generated for the entire image, the block motion vectors are substracted from the global vector to obtain local motion vectors representing the shifts from the global vector, the global vector is encoded with fixed length, the local vectors are encoded with variable length, and the coded global vector and the coded local vectors are multiplexed into the coded video signal to be transmitted.

Method for encoding and transmitting video signals as overall motion

A system for transmission of signals coming from a source and processed by an algorithm that, to minimize data (values+parameters), generates values that are encoded, for example, with variable length. The data flows generated by the algorithm are each ordered in packages with the addition of information of source, of frame and of management before being multiplexed.
