20090067311 | METHOD AND APPARATUS FOR RECORDING SECONDARY INFORMATION ON A RECORD CARRIER - The present invention relates to a method of recording secondary information on a record carrier, in particular on an optical record carrier, besides its content information, whereby it is possible to differentiate the record carrier from other record carrier bearing the same content information, for example by recording an individual identifier. The secondary information is recorded by: forming at predetermined positions dummy patterns ( | 03-12-2009 |
20090067424 | METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING A DATA BLOCK IN A WIRELESS COMMUNICATION SYSTEM - The invention provides methods and apparatus for transmitting and receiving a source data block in a wireless communication system using hybrid automatic retransmission request protocol. According to the scheme provided by the invention, at transmitting side, the source data block or part of source data block that is not decoded correctly at receiving side is divided into a plurality of data segments, each the plurality of data segments may be paded with known data to expand the data segments to be a predetermined lengthen, the data segment is encoded with linear code to be a data packet including the data segment and a redundancy information segment or including only redundancy information, and after that the encoded data packets are transmitted. At the receiving side, when each of the received data packets includes a data segment and a redundancy information segment, decoding is performed directly based on the received data packet, decoding is performed based on the received redundancy information segment and an data segment and redundancy information segment extracted from buffered data packets with a first and second chance to restore the data segment that is not decoded correctly in previous decoding processing. With the additional decoding chance, the scheme provided by the invention can improve decoding probability and thus the transmission efficiency of the system. | 03-12-2009 |
