20110069753 | METHODS AND SYSTEM FOR ENCODING/DECODING SIGNALS INCLUDING SCRAMBLING SPECTRAL REPRESENTATION AND DOWNSAMPLING - A method for encoding and decoding media signals, includes the operations of generating at a transmitting side multiple descriptions associated to data of the media signals through a downsampling operation performed on the data, and decoding at a receiving side the multiple descriptions for reconstructing the data by merging the multiple descriptions. The operation of generating multiple descriptions further includes the operations of obtaining a spectral representation of the data, including bands associated to different ranges, the bands being obtained by a suitable quantization operation and including at least one highly quantized band, that is subjected to a higher degree of quantization. A scrambling operation is performed on the spectral representation by moving the at least one highly quantized band to a different range, the scrambling operation being performed prior the downsampling operation. In decoding, a descrambling operation is performed before the merging operation on the multiple descriptions. | 03-24-2011 |
20110161457 | METHOD AND SYSTEMS OF DISTRIBUTING MEDIA CONTENT AND RELATED COMPUTER PROGRAM PRODUCT - Information codes are arranged in pieces comprised of chunks of bytes over a network, such as a Peer-to-Peer overlay network, including a set of peer terminals. A first peer identifies missing chunks in the received pieces and requests such missing chunks from other peers. The chunks are subjected to a fountain code encoding wherein the chunks in a piece are X-ORed. The first peer is therefore capable of reconstructing a received piece encoded with fountain codes from a combination of linearly independent chunks corresponding to the piece. The chunks are transmitted over the network with a connection-less protocol, without retransmission of lost packets, preferably with a UDP protocol. | 06-30-2011 |
20110184297 | METHOD AND DEVICE FOR ESTIMATING MORPHOLOGICAL FEATURES OF HEART BEATS - A method estimates morphological features of heart beats from an ECG signal. Peaks of the R wave of the ECG are detected and classified using a parallel filtering structure. The first branch implements a bandpass filtering with cut off frequencies of about 10 Hz and 35 Hz, enhancing the signal-to-noise ratio (SNR) of the QRS complex. The second branch estimates morphological features of the heart beat from an alternating current (AC) replica of the ECG signal, that may be used to classify the beat and potentially detect arrhythmias. | 07-28-2011 |
20110196615 | Processing of biological signals - A method processes a signal by storing a template sequence composed of a number N of consecutive digital samples of the signal; calculating a sequence of extended sums that includes, for each digital sample, an extended sum of absolute values of differences between N most recent digital samples and the samples of the template sequence; detecting minima of the sequence of extended sums; and estimating a period of the signal as a time interval between two consecutive minima of the sequence of extended sums. The method also estimates the noise level of the signal as a ratio between most recently-detected minimum and maximum of said sequence of extended sums. The method also generates a reduced-noise replica of the signal as a weighted average of the template sequence and of the current samples of the signal processed between two consecutive minima of said extended sum, the weighted average being calculated using weights based on the estimated noise level. | 08-11-2011 |
20130070861 | METHOD AND SYSTEM FOR THE TREATMENT OF MULTIPLE-DESCRIPTION SIGNALS, AND CORRESPONDING COMPUTER-PROGRAM PRODUCT - A processing system, such as typically a CPU, is used for converting a digital signal organized in pixels, such as a video signal, between a first format and a second multiple-description format. The system comprises at least one input register and at least one output register, and is configured via instructions, that can be constituted at least in part by instructions of a SIMD type, so as to: order the pixels of the signal to be converted in a set of input registers; and take selectively the pixels from the aforesaid set of input registers and place them in an orderly way in at least one output register. | 03-21-2013 |
20130198151 | METHODS FOR FILE SHARING RELATED TO THE BIT FOUNTAIN PROTOCOL - An embodiment relates to distributing media over a peer-to-peer network by employing a digital fountain coding. Accordingly, the file is separated into file portions and the portions are combined to obtain encoded portions which are then transmitted. A file portion may form a part of a plurality of the encoded and transmitted file portions. The portions may be pieces and/or blocks of the file, wherein a piece includes a plurality of blocks. An embodiment further provides mechanisms for efficient block-request-transmission approaches in which the initial requests for blocks in the file are transmitted and additional requests for some random blocks are transmitted. The additional requests may be transmitted after each piece or after the entire file blocks have been requested, or both. | 08-01-2013 |
