摘要： The present invention relates to a method of binary encoding the N points of a constellation corresponding to the discrete positions, in amplitude and in phase, associated with the encoding of binary words in the case of a multicarrier modulation of OFDM type (Orthogonal Frequency Division Multiplexing) of a digitized signal. According to the method, two adjacent points of the constellation correspond to binary words which differ from one another by at most two bits. The present invention applies in particular to digital television.

The spectrum of the signal has two master lines with a fixed frequency difference between them. The method is characterized by the following steps: (1) determination of the start of a transmission interval; (2) determination of the position of the two master lines; and (3) computation of the variation of the phases of these two lines as a function of time, and exploitation of the result to set the frequency of the sampling oscillator and of the intermediate frequency baseband translation oscillator. The invention will find particular application to digital television.

摘要： A projection display device is provided with a negative feedback chain designed to correct all the faults of the projected image, said faults resulting as much from the projection tubes and from their optic systems (geometrical or focusing faults) as from the differences between these tubes (faults in convergence, colorimetry or uniformity of brilliance). The negative feedback chain comprises a test chart generating means, a means to retake the entire projected image and means for the comparision of the signals coming from the test image and from the retaken image. Correction signals are prepared on the basis of this comparison and are applied to the different control circuits defining the projection characteristics. The disclosed device can also be used for the real-time follow-up of the adjustments obtained in a phase prior to the projection of the sequence of useful video images. The invention can be applied notably to video projectors, retro-projection display devices or beam-index tubes.

摘要： A DIDON Digital demodulator includes an input analog-to-digital conversion device which supplies n samples (n being at least equal to 4) during a DIDON period, and an identification device which involves shifts at the sampling frequency in order to search and detect groups of n successive samples which are probably representative of DIDON signals. The probability criteria are a function of the structure of the group under study and of the nature of the DIDON signal which said group may represent in comparison with the nature of the DIDON signal represented by the group which precedes this signal by a DIDON period. The identification device outputs a configuration probability signal and a configuration signal. The configuration signal is received by a data regenerating circuit which then regenerates a data signal and a clock signal when the identification device determines that the configurations are probably DIDON signals.

摘要： The error-correcting device for processing data in parallel on a plurality of tracks provides two levels of correction on the basis of redundancy bits added to the transmitted data, namely bits resulting from coding in blocks of serial data on each channel by means of a shortened Fire code (200, 180), and parity bits each relating to one-half of the parallel tracks. An array of decoders delivers the data corrected on the basis of the bits resulting from the Fire code which are substituted when necessary for the data stored in a memory. When the errors in a block of one of the tracks are too long to be corrected in this manner, two parity computers associated with multiplexers permit determination of the erroneous bits.

摘要： In a digital communication system in which the information is transmitted by successions of bits termed packets, stations may be called upon to perform the function of a relay between other stations. The stations which may be called upon to perform the function of a relay comprise: a checking device which merely checks the address code of a packet received; an eliminating and switching device which either destroys the packet (doubtful address code) or orients the packet toward receiving means pertaining to the station (address code identical to the code of the station) or toward the station corresponding to the address code by passing through a transit memory; and information producing means for producing packets within the station. The contents of the transit memory are transmitted in priority by the station. The packets produced within a station are transmitted in the gaps between the packets coming from the transit memory and in an order which is a function of a classification between the priorities allocated to the information producing means of the considered station.
