A method and apparatus for transmitting a plurality of data streams in a wireless broadcast system are provided. The method includes mapping the plurality of data streams onto a super-frame that includes a plurality of frames; inserting signalling information in a first signalling information field for assisting in the reception of a first number of said plurality of data streams for a given frame, the first number being less than or equal to a limit applicable to each of the plurality of frames; dependent on a number of data streams for the given frame being greater than the limit, inserting signalling information in a second signalling information field; inserting said first and second signalling information fields in a preamble section of said given frame; and transmitting the plurality of frames.

Apparatuses may perform and methods may include: receiving a digital broadcast signal that includes an Electronic Service Guide (ESG); extracting and assembling the ESG; extracting from the ESG signaling information which links one or more services in an upper level layer of a broadcast protocol to a physical layer of the broadcast protocol. Based on the signaling information, one or more services from a broadcast system may be accesses.

A hybrid satellite/terrestrial wireless network having a plurality of terrestrial cells and satellite coverage areas is disclosed. A multiplex transmitted in a terrestrial cell may include signaling information for neighboring terrestrial cells and neighboring satellite coverage areas. The signaling information may include indicators identifying different profiles for the hybrid satellite/terrestrial network, and include other information enabling handover from the terrestrial cell multiplex to one of the neighboring terrestrial or satellite multiplexes.

Disclosed is a digital broadcast receiver including a Digital Multimedia Broadcasting (DMB) module for receiving digital broadcastings of multiple channels; an output unit for outputting voice and image signals of the digital broadcastings; and a controller for controlling the DMB module to receive the digital broadcastings while successively and automatically switching the channels at a predetermined time interval, and controlling the digital broadcasting data received in the DMB module to be transmitted to the output unit.

Certain aspects of a method and system for processing multimedia data may include receiving a DVB-H signal via a DVB-H receiver integrated within a cable modem. The cable modem may include a wireless interface and/or a wired interface. The received DVB-H signal may be routed from within the cable modem to a multimedia device coupled to the cable modem via the wired or wireless interface. An audio signal and/or a video signal may be generated based on the received DVB-H signal, and may be communicated to a multimedia device communicatively coupled to the cable modem. The wired interface may comprise an Ethernet interface or a serial interface. The wireless interface may comprise a WLAN interface. The multimedia signal may include a multimedia standard native to the multimedia device.

Methods and system for transmitting a DVB-H network ID in transmission parameter signaling (TPS) data are described. A sixteen bit DVB-H network ID may be divided into four four-bit portions, and each four-bit portion may be included in an orthogonal frequency division multiplex (OFDM) TPS frame transmitted by the DVB-H network. Because each OFDM TPS frame also includes a frame order of that frame within its corresponding super-frame, a receiver of the TPS data can reassemble the network ID by ordering the four received portions according to the frame order of the respective OFDM TPS frames in which they were received. The sixteen bit DVB-H network ID may alternatively be divided into two eight-bit portions, and each eight-bit portion may be included in the cell_ID bits of two frames of a super-frame.

The invention discloses a live broadcast key point hinting method, a server, a user terminal and a system. The method comprises the steps that an acquisition device acquires the volume of an activity site environment in real time and sends the acquisition value to a server; when the server determines that the acquisition value is greater than a preset threshold value, a live broadcast time-point corresponding to the acquisition value is recorded as a key point, and a key point hinting notification is generated and sent to the user terminal; and the user terminal receives the key point hinting notification and hints a user. According to the invention, when live broadcast is carried out, the user is timely hinted at the live broadcast key point; the user can focus on watching the live broadcast at the live broadcast key point; and the problem of serious live broadcast watching experience missing, which is caused by the fact that the user misses the live broadcast key point, is effectively prevented.

Disclosed is a DVB-H CBMS system by which a user can continue to view a program being in service even when the transport stream or IP platform changes while the user views the program. In the DVB-H CBMS system, the system transmits service mapping information according to transport streams or IP platforms to the terminal, so that the system can provide a service without interruption to the terminal even when a user of the terminal moves out of a current cell or network into a new cell or network while receiving a service that the user selected.

A method and apparatus for tracking the transmission power level of a home network transmission signal based on the signal level of a received broadcast signal is described. The method includes transmitting a signal at a first transmitted level used for communicating in a home network, detecting a signal level for the transmitted signal in a circuit used for receiving a broadcast signal, determining if a gain setting value for the signal level changes, and adjusting the transmitted signal level for the transmitted signal based on the determination. The apparatus includes a network circuit that transmits a signal at a first transmitted signal level, a detector that detects the transmitted signal in a circuit for receiving a broadcast signal, and a controller that determines if a signal level setting value for the signal level changes and adjusts the transmitted signal level based on the determination.

A mobile terminal and method of controlling a broadcast therein are disclosed, by which a currently-output broadcast content can be continued to be output despite expiration of a validity term of a broadcast viewing authority. The method includes acquiring a first broadcast viewing authority, receiving and outputting a first broadcast content if the first broadcast viewing authority is acquired, determining whether a validity term of the acquired first broadcast viewing authority expires within a broadcast time of the output first broadcast content, and if the validity term expires within the broadcast time, displaying an image for a purchase of the first broadcast content.

FDM based broadcast transmitter arrangement for transmitting a digital audio/video information signal, wherein an encoded version of the digital audio/video information signal is encapsulated in a network layer encapsulation step in accordance with DAB, DVB-T or DVB-T2 to obtain a network layer information signal. The network layer information signal is then converted in a Data Link Layer conversion step to obtain a Data Link Layer information signal, which is subjected in a Physical Layer conversion step to obtain a broadcast information transmission signal.
