Abstract: The apparatus (100) has base layer and additional layer processing units (101, 102) to convert first and second sets of elementary streams e.g. audio/video signals, corresponding to base and additional layers into packets that are multiplexed to generate base layer and additional layer transport streams, respectively. A multiplexing unit (160) multiplexes the transport streams to generate a broadcasting stream e.g. digital multimedia broadcasting (DMB)transport stream. A transmission processing unit (170) transmits the broadcasting stream via a transmission channel. The base layer and additional layer transport streams are MPEG-2transport streams. Independent claims are also included for the following: (1) a method for carrying out transmission in a digital broadcasting system (2) a receiving apparatus for a digital broadcasting system (3) a method for carrying out reception in a digital broadcasting system.

Abstract: In a diverse wireless system employing QAM modulation of symbols received via different fading channels, an input vector signalxcomprising subvectorsx1-kis iteratively constellation-rotated 110 through a number of rotations n, divided into real and imaginary values 120 and cyclically shifted 130 to generate a final rotation vector signalr. When this signal is received (410), a signal construction unit (420) generates new rotation vector signals via a constellation rotation 0k and the signals are grouped into pairs (510) and input to a complex signal construction unit (520) for cross-coupling (fig. 6).

Abstract: The terminal (130) has a data transmission unit for transmitting information concerning a point in time to decode a portion of contents received using a broadcasting network (120) i.e. terrestrial multi-media digital broadcasting network, with a communication network (140). A receiving unit receives a remaining portion of the contents received from the communication network after the point in time to decode the portion of the contents that run-out. A transfer control unit controls transferring of the contents from the broadcasting network to the communication network. The information includes a value depending to a group including a system clock value of the contents, a packet counter value of the contents and a reference value of coordinated universal time.

Abstract: Es wird eine Vorrichtung für eine optische Netzwerkeinheit (ONU-Vorrichtung) in einem Kabelnetzwerk zur Verfügung gestellt. Die ONU-Vorrichtung enthält ein Kabelmodem, das zum Empfangen von Synchronisationsinformation von einer Kopfstelle durch eine optische Leitung konfiguriert ist, und eine Edge-Quadraturamplitudenmodulation (EQAM), die zum Durchführen einer Synchronisation mit einem in der Kopfstelle enthaltenen Kabelmodemabschlusssystem (CMTS) auf der Basis der Synchronisationsinformation und zum Modulieren eines empfangenen Signals zu einem Funkfrequenz-(RF-)Signal für eine Teilnehmervorrichtung konfiguriert ist. Strukturen mit tief in das Netzwerk gehenden Glasfasern und Mikrozellen können auf einfache Weise angewendet werden, indem zugelassen wird, dass die EQAM nicht einer Kopfstelle sondern in der ONU lokalisiert ist.

Abstract: An apparatus for transmitting data in a digital broadcasting system is disclosed. The apparatus includes: a source encoding unit for encoding data to be transmitted and generating source-coded data; a capacity managing unit for dividing the source-coded data into divided data for a plurality of channels in case that an available data capacity for transmitting the source-coded data does not exist in one channel but sum of available data capacities of the multiple channels can accommodate the source-coded data, and adding header information to the divided data; a channel encoding unit for encoding the divided data according to channel environment and generating channel-coded data; and a transmitting unit for multiplexing, modulating and transmitting the channel-coded data through multiple frequency bands and multiple broadcasting sites.

Abstract: The method involves receiving a package of a flow of coded video stream coming from a video coder through an interface screen. A transport interface is reconfigured, and a signal is transmitted through a broadcasting network. The flow package is stored in a database (412), where the flow package has a reference value for a program clock. A frame of a transport interface is provided in a queue. A research is performed in the queue corresponding to a request from a user who carries out an access through a communication network. The package is transmitted through the communication network. An independent claim is also included for a device for providing a video service.

A synchronization unit (103) generates information of a reference clock program of the transport stream to the base layer based on a system clock time. A multiplexing unit (160) generates a broadcasting stream by multiplexing a broadcast transport stream of the base layer with a dummy package. A transmission processing unit (170) transmits the broadcast stream through a transmission channel. Independent claims are also included for the following: (1) a method for synchronizing transport streams in a digital broadcasting system (2) a receiving apparatus comprising a receiving unit for receiving transport streams in a digital broadcasting system (3) a method of receiving transport streams in a digital broadcasting system.
