20090158378 | METHOD AND SYSTEM FOR TRANSMITTING DATA BETWEEN A CENTRAL RADIO STATION AND AT LEAST ONE TRANSMITTER - First data is transmitted between a central radio station and at least one transmitter, where the first data is in first data fields of data packets and useful data is in second data fields of the data packets. The first data fields in this context are pre-reserved by the central radio station for the transmission of second data between the transmitter(s) and the receivers. | 06-18-2009 |
20090175356 | METHOD AND DEVICE FOR FORMING A COMMON DATASTREAM ACCORDING TO THE ATSC STANDARD - A method and a device for forming a common transport datastream from several mobile-digital television signal datastreams and a common stationary-digital television signal datastream. A constant number of data units of respectively-constant size in every successive time interval with constant cycle duration for the transmission of every individual datastream is determined. A data structure is specified for the common datastream with successive sequences in each case of a constant number of data units with respectively-identical positions for data units of the stationary-digital television signal and respectively-identical positions for data units of the mobile-digital television signal. Data units of each of the datastreams of the mobile-digital television signal are transmitted in each case in associated, identical positions of at least one successive sequence, and define the individual positions of the data structure of the common datastream with data units of the respectively associated datastreams. | 07-09-2009 |
20100085489 | Methods and Apparatus for Generating a Transport Data Stream with Image Data - A transport data stream is generated by generating a data stream of successive second data frames with a GOP structure for each program containing image data of an image of an image sequence recorded digitally and belonging to the respective program by a source encoder. The transmission start, transmission period and transmission time are determined. At the start of first data frames, second data frames realized as P-frames or B-frames to be transmitted are replaced by second data frames realized as I-frames in each of the data streams belonging to a program and each first data frame of the transport data stream is packed with second data frames of data streams belonging in each case to one program whose transmission time fits the transmission start and the transmission period of the respective first data frame by means of a multiplexer. | 04-08-2010 |
20100238916 | METHOD FOR IMPROVING THE DATA RATE OF MOBILE/HANDHELD DATA AND THE QUALITY OF CHANNEL ESTIMATION IN AN ATSC-M/H TRANSPORT DATA STREAM - A method for improving the data rate of data for M/H receivers and for improving the quality of channel estimation in an ATSC-M/H transport data stream marks the transport data packets determined for the transmission of data for M/H receivers in N (e.g., 38) consecutively transmitted transport data packets in an ATSC-M/H-slot of the uncoded ATSC-M/H transport data stream originally determined for the transmission of data for stationary receivers. Coded data for M/H receivers are inserted in the marked transport data packets and introduce training sequences in segments of data fields of the coded ATSC-M/H transport data stream containing marked transport data packets. | 09-23-2010 |
