Apparatuses may perform and methods may include receiving a digital broadcast signal that includes a physical layer pipe identified by a predetermined identifier indicating that the physical layer pipe includes service guide bootstrap information. The bootstrap information may identify one or more service guides available for download. The physical layer pipe may include header information that identifies one or more other physical layer pipes containing portions of the service guides identified in the bootstrap information. Based on the bootstrap information and header information, a selected service guide is retrieved and presented to a user.

Accessing service guide information in a digital video broadcast system

An approach is provided for providing audio-based control for at least one device based on changes in the rendering of audio information. A control platform causes, at least in part, a transmission of audio information from at least one device to an audio playback assembly for rendering. The control platform further determines at least one indication of a change in the rendering, wherein the at least one indication is based, at least in part, on one or more controls associated with the audio playback assembly. The control platform also processes and/or facilitates a processing of the at least one indication to cause, at least in part, an execution of at least one function for controlling the rendering of the audio information.

Method and apparatus for providing audio-based control

Provided are apparatuses and methods for detecting neighboring cells in a communication network based on Transmission Parameter Signaling (TPS) bits received in a signaling frame. In one example, a signaling frame contains a field of TPS bits that indicate a type of the signaling frame. The type of the signaling frame may indicate the information carried in the signaling frame as information of a current cell or a neighboring cell. The signaling frame may further include information from a neighboring cell in the same network or a different network as the current cell. The signaling frame may further be arranged in a superframe in which the a plurality of frames are transmitted to a receiver in a certain sequence. Each frame in a superframe or a sequence of frames may include a parameter for defining the location of the frame.

Method and system for signaling neighboring signals in TPS bits

Embodiments are directed to defining hierarchical digital broadcast transport streams as separate cells, which reduces the signaling in OSI layer 1, and removing use of sub-cells so that the coverage area of a transposer may be treated as a cell. In accordance with at least one embodiment, each hierarchical DVB-H stream (i.e., the HP stream and the LP stream) has its own separate dedicated 'current signal' frame. This allows the streams to be independent of each other (even to belong to different networks). Furthermore, in accordance with the hierarchical signal arrangement, a cell can be uniquely identified by its network_id and cell_id. In accordance with at least one embodiment, frequency may be used as an additional identifier thereby allowing a first cell to be transposed to a sub-cell.

Method and system to signal network information in TPS bits

Embodiments may include apparatuses, computer media, and methods for receiving at least one data symbol for transmission in a data frame, generating signaling information that identifies transmission parameters for the data frame, wherein the signaling information includes a first signaling portion and a second signaling portion, wherein the second signaling portion includes at least a third signaling portion and a fourth signaling portion, generating at least one first size information for the third signaling portion, generating at least one second size information for the fourth signaling portion, adding the at least one first size information and the at least second size information to the first signaling portion, and assembling, by at least one processor, the data frame comprising at least the first signaling portion, the second signaling portion, and the at least one data symbol.

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.

Method and system to enable adaptation between physical bearers and OMA-BCAST

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.

According to an embodiment of the invention, an apparatus includes a decoder configured to decode transmission parameter signaling data from a signal, the signal including the transmission parameter signaling data on a lower level than a level on which service information is included; and a determiner configured to determine from decoded transmission parameter signaling data if the signal carries time-sliced elementary streams and configured to determine from the decoded transmission parameter signaling data whether the signal has a forward error correction framing structure, wherein the apparatus is a receiver and is configured to operate in a network. The apparatus further includes a controller configured to disregard a signal in response to determining that the signal does not carry time-sliced elementary streams.

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.
