摘要： Für die Übertragung von digitalen Rundfunksignalen werden ETI-Signale benötigt, die mit einem korrekten DAB Mode ausgebildet sein müssen. Bisher können ETI-Signale nur zwischen den DAB Modi 1,2 und 4 umgewandelt werden, da diese Modi jeweils drei Informationsblöcke (FIB) pro Zeiteinheit aufweisen. Bei dem DAB Mode 3 werden jedoch vier Informationsblöcke (FIB) je Zeiteinheit verwendet. Um auch die Umwandlung eines ETI-Signals in einen DAB Mode 3 zu ermöglichen, wird erfindungsgemäß vorgeschlagen, die drei Informationsblöcke (FIB1, FIB2, FIB3) des ETI-Signals mit einem vierten Informationsblock (30) zu ergänzen. Der vierte Informationsblock (30) ist als Dummy-FIB ausgebildet, so dass die Bedingungen des DAB Mode 3 Formats erfüllt sind. Alternativ können für den vierten Informationsblock (30) auch ein oder mehrere nutzbare Informationsgruppen (FIG) eines Informationsblocks (FIB) kopiert und verwendet werden.

摘要： A modulation scheme (600) useful in a voice paging system in which both of two orthogonal modulation components (500 and 510) are used to carry two halves of a single voice message destined for a receiver, or two separate voice messages for a receiver. The single voice message is transmitted in half the time.

摘要： A broadcast reception apparatus (1) performs switching of a broadcast in which a URL of an IP radio station having the relationship of a simultaneous broadcast with the broadcast is not obtained to an IP radio. When a reception of a DAB service is started at a first time point, a URL of an IP radio station having the relationship of a simultaneous broadcast with the DAB service is obtained from a Radio DNS (5) and stores the URL. Thereafter, when reception quality of the DAB service is deteriorated at a second time point, a reception of an FM broadcast station having the relationship of a simultaneous broadcast with the DAB service is started. Thereafter, when reception quality of the FM broadcast station is deteriorated at a third time point, a reception of the IP radio station indicated by the stored URL is started.

摘要： A system for peak-to-average-power ratio (PAPR) reduction of a frequency shifted plurality of digital broadcast signals taking into account the combined signal peaks in order to transmit the signals more efficiently in a single broadcast transmission system. The PAPR algorithm takes into account a rotating constellation phase offset for the shifted signals corresponding to the amount of applied frequency shift. In the case of a dual sideband In-Band-On-Channel (IBOC) signal typically used in conjunction with an FM carrier in the center, the sidebands can be interleaved to create a new IBOC signal definition and take the place of the FM carrier for an all-digital transmission that is backward compatible with IBOC receivers allowing for a gradual migration to all digital broadcasting.
