20110060974 | METHODS AND DEVICES FOR TRANSMITTING A DATA STREAM AND CORRESPONDING COMPUTER READABLE MEDIA - A data stream is transmitted from a transmitting device to a receiving device via a communication network. Data of the data stream is transmitted to the receiving device by using a transport protocol without data acknowledgement. In a transmission method, parity-encoding parameters for parity encoding a data set of the data stream is determined via the transmitting device. The transmitting device also generates parity data from the data set by using the determined parity-encoding parameters. The transmitting device further transmits the generated parity data to the receiving device via the communication network by using a transport protocol with data acknowledgement. | 03-10-2011 |
20130044835 | Data blocks encoding and transmission over a diversity communication network - The invention relates to a method of transmitting a data unit over a plurality of transmission paths of a wireless communication system that is adapted to minimize bandwidth usage and energy consumption while maintaining transmission robustness. A method of transmitting K data blocks of a data unit comprises the steps of encoding the data unit into an encoded data unit comprising N encoded blocks, with N>K, using an error correction code having a minimum distance d; and transmitting the N blocks of the encoded data unit over a set of N | 02-21-2013 |
20130128987 | Communication of data blocks over a communication system - The invention relates to a method of transmitting and receiving a primary data stream of data blocks, each data block formed by a plurality of N symbols, over a communication system that is robust to transmission errors and signal interruptions due to obstacles, and that minimizes bandwidth usage. The transmitting method comprising: forming a secondary data stream comprising shortened data blocks formed from the M most significant symbols of data blocks of the primary data stream, where M05-23-2013 | |
20130156109 | METHOD OF TRANSMITTING VIDEO INFORMATION OVER A WIRELESS MULTI-PATH COMMUNICATION LINK AND CORRESPONDING WIRELESS STATION - The present invention a method of transmitting video information over a communication link made of several transmission paths between wireless transmitting and receiving stations. The method comprises, in the wireless transmitting station, obtaining an uncompressed video frame made of an array of pixel blocks, a pixel in the pixel blocks being represented by base pixel information and enhancement pixel information; generating at least one set of complementary pixel blocks from a given pixel block of the obtained uncompressed video frame, by applying different operations to said given pixel block for dropping different enhancement pixel information from that pixel block, so that the complementary pixel blocks comprise different enhancement pixel information and each comprises the base pixel information; and for each set, transmitting the complementary pixel blocks over respective different transmission paths to the wireless receiving station. This provides robustness of video transmission while keeping a high quality of video rendering. | 06-20-2013 |
20130208708 | Method and device for collaborative data communication in a radio network - The present invention relates to communication between collaborative nodes configured to collaboratively communicate in a radio network. A corresponding method comprises: sending, by each active node of the set of collaborative nodes, an RTS message for the same transmission slot; sending, by one of the active nodes, referred to as coordinator node, a CTS message to acknowledge reservation of said transmission slot on behalf of all the active nodes, upon receiving the RTSs; wherein the transmission slot is divided, based on the sent RTSs, into sub-slots for respective active nodes to transmit data packets. The invention provides an improved use of the reserved transmission slot, and a reduced waste of reserved time. | 08-15-2013 |
