摘要： Embodiments provide power-efficient mechanisms for communicating small amounts of information to receiver devices within a mobile broadcast system. A generic transport mechanism enables transmitting data relevant to upper layer protocols in a lower layer sub-channel so multiple information summary flows can share the same physical layer sub-channel Data fields are added to the Overhead Information Service (OIS) channel to provide power-efficient logical channels for carrying the summary information. Data from the power-efficient logical channels are provided to an upper protocol layer that receives the information summary flows. Information summary flow may carry a version number of an information flow in the broadcast signal, codes or other information. Receiver devices periodically monitoring the OIS receive the information summary flows. Employing an embodiment, a receiver device can minimize power consumption because reception of the OIS can indicate whether any new information flows are available, obviating a need to periodically check information flows.

摘要： Embodiments enable mobile devices to efficiently receive mobile broadcast content corresponding to a user's selections based upon content description metadata transmitted in a content description flow portion of broadcast transmissions. A content description flow may be in the form of broadcast data packets which include information about the nature of content elements to be broadcast. Using the information in the content description flow, a mobile device can determine whether a particular portion of content is of interest, as well as when the content will be broadcast and the content flow address on which it can be received. Enabling mobile devices to screen broadcast content flows by monitoring the content description flow for content of interest can extend their battery life since the content description flow can be quickly downloaded and the receiver de-energized if no content is of interest to the user.

摘要： Embodiments provide bandwidth efficient mechanisms for delivering rich media content, such as webpages, to receiver devices via a multimedia broadcast network. Content, such as selected webpages, is broadcast as disassembled content elements via the broadcast network. To enable reception, the disassembled content elements are broadcast according to a broadcast schedule that is communicated in an overhead content description flow, such as a catalog file. Receiver devices receive the catalog file and use the metadata information to selectively receive disassembled content and store the content elements in memory. When a user requests access to the content (e.g., a webpage via a web browser), an application operating in the receiver device assembles the requested content from the previously received and stored disassembled content elements, and passes the assembled webpage to a using or rendering application.

摘要： Information included within metadata broadcast within an overhead flow of a mobile broadcast network enables receiver devices to determine when metadata updates will occur. The mobile broadcast network can include within metadata messages information related to a time for the next metadata update. Using this information, receiver devices can determine when the next metadata update will occur and de-energize the receiver until that time. Enabling mobile devices to remain de-energized until the next metadata update improves their power efficiency. Synchronizing mobile devices to access the overhead flow for updated metadata reduces the content delivery latency that the system must accommodate, thereby improving system flexibility and bandwidth efficiency. Specify the time of a next metadata update enables the broadcast system to change the rate and timing at which metadata updates are performed.
