This device for extracting binary information elements of a defined frame structure including, in addition to the time slots reserved for transmitting information signals, time slots reserved for transmitting auxiliary signals includes: - division means (1) for dividing the incident digital train, with data rate D, into "n" digital trains of reduced data rate D/n, - memory means (2, 4, 5) for storing at least 2n+(m-1) consecutive binary elements of the incident digital train obtained at the output of the said division means, where m designates the maximum number of consecutive auxiliary binary elements capable of being present in the incident digital train, with m - selection means (7) for selecting, at each instant defined by the reduced rate D/n, "n" binary elements from among the binary elements contained in the said memory storage means, and - means (7') for control of the said selection means. <IMAGE>
