摘要:
In a digital broadband broadcast transmitter, digital data is time interleaved for transmission, and the time interleaved digital data is transmitted in a digital broadband broadcast transmission towards a plurality of receivers. A cellular transmitter is operated in an apparatus. In the same apparatus, the digital broadband broadcast transmission transmitted by the digital broadband broadcast transmitter is received, and the received digital broadband broadcast transmission is time deinterleaved.

Aspects of the invention provide methods, apparatuses and computer media for providing cell location information in a digital broadcasting system. A mobile terminal uses the cell location information to form a preliminary handover candidate list. A mobile terminal receives reference coordinates for a reference cell, displacement coordinates for a current cell, and displacement coordinates for neighboring cells over a wireless channel. The mobile terminal consequently determines the locations of the current cell and the neighbor cells based on the coordinates. The mobile terminal determines a range distance for the current cell and includes a neighboring cell in a handover candidate list when the neighboring cell is within the range distance, where the range distance is based on an estimated maximum radius of the current cell and optionally on a cell coverage offset. The handover candidate list is further sorted based on distances of the handover candidates from the current cell.

Broadcast configuration data such as service information, program specific information and electronic service guide data may be misconfigured in non-standard or misconfigured broadcast networks. A network and data analysis server may be used to monitor network broadcasts for configuration information, check whether the configuration information is valid and transmit updated information to a central service discovery database system. The service discovery database system may be used to repair misconfigured or incomplete configuration information before storing it to a database. Terminals with fast service discovery enabled or that have received misconfigured data through the broadcast network may request configuration data from the service discovery database system. Additionally, terminals and/or network analysis servers may receive broadcast signals through a first network connection while communicating with the database system over a second network connection.

Systems and methods are provided that combine Open Mobile Alliance Mobile Broadcast Services (OMA BCAST) with different bearers, such as China Multimedia Mobile Broadcasting (CMMB) by associating service-related identifiers within an OMA BCAST Electronic Service Guide (ESG) with CMMB bearer-specific parameters. Furthermore, associating IP source and/or destination address pairs of a service with the location of the service within the CMMB bearer can be achieved and used with unicast, multicast, and broadcast environments. Further still, systems and methods are provided that allow for ESG bootstrapping, where a desired electronic service guide can be discovered by bootstrapping, e.g., OMA BCAST ESG.

The projector is configured to project a first moving picture. The camera configured to capture a combined moving picture. The combined moving picture includes the projected first moving picture and a second moving picture displayed from another device. The apparatus is configured to perform an action based upon the combined moving picture.
摘要:
Components of a transmitted service delivering multiple versions of content are mapped to streams carrying data for those multiple versions. The data streams are encapsulated into User Datagram Protocol (UDP) packets; the UDP destination port fields of the packets are given component-identifying values. A user equipment (UE) receiving the transmitted service identifies desired components based on the UDP destination port field values. The UE further encapsulates desired component UDP packets into Internet Protocol (IP) packets, and may assign component-identifying values to fields of the IP packets (e.g., the IP source address and/or IP destination address).

摘要:
In accordance with an example embodiment of the present invention, a method and apparatus are described for mapping one or more layers of a scalable media stream to at least one physical layer pipe of a transmission. Information related to the mapping is transmitted. Also, the one or more layers are transmitted in the at least one physical layer pipe. Further, a method and apparatus are shown for receiving data in a transmission in at least one physical layer pipe. Information is received in related to a mapping of one or more layers of a scalable media stream to the at least one physical layer pipe. Based on the received information related to the mapping, the one or more layers of the scalable media stream in the received data are identified.
