PURPOSE: A method for transceiving signaling information for receiving a broadcast service in a digital broadcasting system and a device thereof are provided to efficiently receive signaling information by providing a transmission network required for an IP profile of DVB-NGH and signaling information of a transmission network physical layer. CONSTITUTION: A signaling information generator generates ULI(Upper Layer Information)(510). The signaling information gene generates NMI(Neighboring Multiplexes Information)(530). The NMI includes network information and physical layer information. An SGDD(Service Guide Delivery Descriptor) generator includes the ULI and NMI in an SGDD. The SGDD generator generates the SGDD(550). An SGDD transmitting unit transmits the SGDD to a receiving unit(570).

PURPOSE: A frame structure of a wireless broadcast system, and a method for transmitting and receiving data streams through the frame structure and a device thereof are provided to set different repetitive lengths for configuration data items of different types. CONSTITUTION: A set of Qn non-allocation PLP(Physical Layer Pipe)s is determined(S400). Each non-allocation PLP has n which is a desired repetitive length. The number of PLPs is set by Qn when Qn is the same as n or a multiple of n(S402,S406). Configuration data items with the determined set are classified into n groups(S408). If the configuration data items do not exist, data are transmitted by arranged frames(S410,S414).

Abstract:
PURPOSE: An additional signaling method and an apparatus thereof for digital video broadcasting are provided to increase the capacity of a preamble section for accepting signaling modes. CONSTITUTION: First and second data fields are encoded for generating first and second modulation patterns(710). A D-BPSK(Differential-Binary Phase Shift Keying) modulation is applied to the first data sequence in order to generate a first modulation sequence(720). The first data sequence is scrambled in order to generate the scrambled first modulation sequence(730). A second data sequence is generated to encode n3 bits of a third data field(740). The second data sequence is modulated through a D-BPSK modulation mode(750).

PURPOSE: A method for transmitting and receiving data including a plurality of data streams in a broadcast/communication system and an apparatus thereof are provided to receive the multiple data streams by using signaling information. CONSTITUTION: A frame is divided into a plurality of physical layer regions. A plurality of data streams is allocated to the multiple physical layer regions. Signaling information related to the divided multiple physical layer regions is allocated to one or more physical layer regions. The frame including the signaling information is transmitted. The signaling information comprises one or more information among position information of the physical layer region, characteristic information of the physical layer region, and allocation information with respect to the physical layer regions. Data comprises one or more elements related to the number of sub-carriers of an OFDM(Orthogonal Frequency-Division Multiplexing) symbol, a protection length between the OFDM symbols, a ratio of a pilot sub-carrier to a payload sub-carrier, and a multi-antenna transmission method.
