Abstract: Embodiments enable multimedia broadcast systems to temporarily suspend broadcast of data in an active content flow when insufficient data is available for efficient use of the broadcast bandwidth, while signaling receiver devices so they may deactivate receiver circuits to conserve power while data broadcasts are suspended. Flow content received in the broadcaster during the temporary suspension of data broadcasts may be stored in flow buffers for broadcast at the end of the temporary suspension. An indication of the duration of suspended data broadcasts may be included in the overhead information symbols (OIS) within the broadcast signal. Receiver devices receiving the indication of suspended data broadcasts may deactivate their receiver circuits for the indicated duration. The broadcast suspensions may be coordinated across multiple content flows so that receiver devices can periodically wake up at induced sleep intervals to monitor any data flow of the broadcast system.

A user interface status and/or a flow status can be monitored. Based at least in part on the user interface status and/or the flow status, a determination can be made as to when and/or how often monitoring is to be performed.

Abstract: Methods, systems and devices are provided for receiving, at a receiver device, a data block or file containing a plurality of application symbols, determining the number of application symbols received in the block, generating a metric based on the number of application symbols received in the block, and transmitting the metric to a server.

Abstract: Receiver devices may receive broadcast content and decode data on multiple carriers in time division mode, and change carriers to receive data from different radio frequencies. Embodiments include methods, systems and devices that enable scheduling content for broadcast by two or more mobile TV broadcasters so that non-exclusive real time content broadcasts in one radio frequency band does not overlap with non-real time content broadcast in another radio frequency band, enabling simultaneous reception of non-real time broadcast by one network and non-exclusive real time content broadcast by another network. Receiver devices may simultaneously receive non-real time content on two or more radio frequency bands and real time content on any of the radio frequency bands.

Abstract: Systems, methods, devices, and computer program products are described for wireless broadcast system provisioning. In such a system, there may be a number of wide broadcast areas. Within each wide broadcast area, there may be a number of local broadcast areas. Wide broadcast area content may be assigned to a wide broadcast area scrambling differentiator. The scrambling differentiator may be assigned to a carrier tag. The association between the wide broadcast area content, wide broadcast area scrambling differentiator, and the carrier tag may be common across neighboring wide broadcast areas. Data may be transmitted in a wide broadcast area control channel to identify the association between the carrier tag and the wide broadcast area scrambling differentiator.

Abstract: Methods, systems and devices provide mechanisms and systems for efficiently delivering files over a broadcast system to mobile devices. Files for broadcast may be logically identified as belonging to a directory in a file system. A Broadcast Schedule Message may inform receiver devices of files that will be broadcast at a specified time, as well as describe the files. File may be transmitted in file delivery pipes, which may be of different bandwidth and data rates. Receiver devices configured according to the embodiments may make use of the broadcast schedule message to select files to be received based on the service or application with which the file is associated, and whether the file is new or an update to a previously received file. Receiver devices activate receiver circuitry to capture the files within their advertised broadcast window, and pass the received files to applications or services requesting the files.

Abstract: Methods and systems simplify discovery and handoff for multi-frequency broadcast receiver devices, such as mobile TV devices, by providing a virtual home channel that is not dependent on a single frequency network upper layer. The methods and systems may be used in conjunction with a single frequency network upper layer to support areas without upper layer available, or to off load some portion of the common data bandwidth in the single frequency network. For example, the single frequency network may only carry frequency data for the multiple frequency network or only the frequency data for networks with comprehensive market metadata.

A system for receiving data includes a receiver configured to receive a radio frequency communication signal comprising at least one superframe having at least a first data stream encoded therein; and overhead information carried in the superframe, the overhead information comprising a control channel, the control channel having control channel information for separating the at least one first data stream from any other data streams encoded in the at least one superframe.

Abstract: 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.

Abstract: A communication network node, such as a radio base station or base station controller in a wireless communication network, is configured to monitor and control ingress and egress data congestion. As such, node-based congestion monitoring provides a method of flow control between network nodes and, as such, for example, it may be used to control congestion on backhaul links between radio base stations and base station controllers, and on sidehaul links between base station controllers. In one embodiment, the node monitors egress and ingress data congestion conditions, and marks ingress data incoming to the node to indicate congestion. For example, if ingress data markings indicate ingress data congestion, the node can send signaling to initiate a reduction in the amount of data being sent to the node, e.g., a reduction in ingress data rates. If ingress data markings indicate egress data congestion, the node can reduce egress data rates.

Abstract: Implementations relate to systems and methods for encoding block data to deliver content to a mobile wireless or other device. Content, such as audio, video or textual content, can be generated for broadcast in source blocks that are decomposed into a set of high priority blocks and a set of low priority blocks. Forward error correction is performed on the set of high priority blocks and set of low priority blocks to generate a set of repair symbols for use in reconstructing aggregate transmission blocks of content. The set of low priority blocks and set of repair symbols for a subsequent period can be shifted or inserted into an aggregate transmission block of a prior period. When a request to change channels is received, the decoding of the high priority block corresponding to the content of the new channel can begin before subsequent aggregate transmission blocks are received.

Abstract: A radio base station performs reverse link rate control in a wireless communication network by “stealing” bits on a forward common power control channel. The forward common power control channel is divided into a plurality of frames, with each frame including a plurality of power control groups and each power control group including a plurality of power control slots. The radio base station may dynamically select power control slots depending on user demand to be used for reverse link rate control.
