| 7424409 | Stochastic modeling of time distributed sequences Apparatus for building a stochastic model of a time sequential data sequence, the data sequence comprising symbols selected from a finite symbol set, the apparatus comprising: an input for receiving said data sequence, a tree builder for expressing said symbols as a... | 09/09/2008 |
| 7095344 | Digital signal encoding device, digital signal decoding device, digital signal arithmetic encoding method and digital signal arithmetic decoding method In a bit stream syntax containing compressed video slice data for compressed video data of a slice structure, a slice header for compressed video slice data has attached thereto a slice start code, a register reset flag indicating whether a register value, which des... | 08/22/2006 |
| 6072829 | Method of higher value step encoding To achieve economy of a transmission path with good quality of transmission and low expenditure compared to previous codes such as 4PSK-64PSK, the invention provides higher-value pulse duration encoding, such that there is provided only an alternating cur... | 06/06/2000 |
| 5587797 | Process for encoding and transmitting information The present invention relates to process for encoding and transmitting information wherein data, digitalized speech, image, or documents, optionally in colour, are encoded by multilevel combination code with multilevel code elements into a signal, in part... | 12/24/1996 |
| 5268686 | Data compression method The method is founded on the GUAZZO algorithm and is adaptive as it does not require any prior statistical knowledge of source of message to be coded. The message is comprised of a sequence of symbols of the source which are represented by the indication ... | 12/07/1993 |
| 5142283 | Arithmetic compression coding using interpolation for ambiguous symbols A method for substituting interpolated values for ambiguous symbols in an arithmetically encoded symbol string, symbols in the unencoded original string being drawn from a Markov source and a finite alphabet. Ambiguity of a symbol is defined as where its ... | 08/25/1992 |
| 4978955 | Data randomizing/de-randomizing circuit for randomizing and de-randomizing data A circuit for randomizing data or de-randomzing previously randomized data according to a randomization scheme utilizing an irreducible generator polynomial which operates on a serial bit stream of words of data which is supplied to said circuit in a form... | 12/18/1990 |
| 4694244 | Apparatus for random repetitive sampling Methods and apparatus for random repetitive sampling in digital oscilloscopes is disclosed using a psuedo-random noise generator to vary randomly the beginning of a search for a trigger event to enable the acquiring of data which has no gaps.... | 09/15/1987 |
| 4068228 | Multiple channel amplifier An amplifier for an electromagnetic radiation receiver has a plurality of amplification channels for the determination of angular separations, especially for use in self guiding equipment in missiles in which each amplification channel has several amplifi... | 01/10/1978 |
