Abstract

Method and device for processing asynchronous data.Applicable in compressed video signal processing systems whose purpose is to guarantee the maintenance of the synchronisation of the cells in Asynchronous Transfer Mode (MTA), in communication networks that are not MTA, and uses existing video encoding and decoding systems for MTA networks.The method has a first stage that reads the MTA cells from the video encoder and determines whether each cell contains useful information or not. It has a second stage in which if the cell contains useful information, it is sent to the communications network, but if it does not contain useful information, the number of consecutive empty cells received are counted, generating a "group" type cell whose information field contains the final value of the count performed the "group" type cell is sent to the communications network. It has a third stage for receiving and reading the cells received from the communications network, determining for each cell whether it is a "group" type cell or useful "info" type cell. It includes a fourth stage in which if the cell received is an "info" type cell, it is sent to the video decoder, but if it is a "group" type cell, the final value of the count contained in its information field is extracted and as many empty cells as indicated in said value are sent to the video decoder in order to obtain at the video decoder input the same sequence of MTA cells than that of the video encoder output.The device performs the various stages of the method.
