Embodiments include methods implemented by a processor of a mobile communication device for managing tune-aways by a radio frequency resource supporting a first subscription to support a second subscription. The processor may determine a data loss ratio of the data of a media file that is lost in transmission to the mobile communication device. The processor may compare the data loss ratio of the data to a first data loss ratio threshold and a second data loss ratio threshold, and the processor may block a tune-away event of the radio frequency resource from the first subscription to the second subscription in response to determining that the data loss ratio of the data is greater than the first data loss ratio threshold and less than the second data loss ratio threshold.

Evolved multimedia broadcast multicast service (eMBMS) streaming loss control in a radio sharing concurrent radio access technology (RAT) capable mobile device

Distributed computing is disclosed in which a client device accesses a service announcement for a broadcast service in order to retrieve transport parameters describing a data transmission service. The client device obtains a refresh rate from the service description file, which is separate from the data transmission service, wherein the refresh rate relates to a frequency at which the data transmission service updates data in a data transmission provided by the data transmission service. The client device uses the transport parameters to access the data transmission to receive the data. Once the data is received, the client device will delay any subsequent access to the data transmission to get updated data for a delay time based at least in part on the refresh rate.

Signaling of refresh rate for efficient data update in distributed computing environments

In one example, a device configured to receive a first sub-segment of a segment of multimedia data, the first sub-segment comprising a first set of one or more data units and a first header including data indicative of locations of the data units within the first sub-segment, wherein at least one of the data units refers to a data unit of a second sub-segment of the segment. The device is also configured to, after receiving the first sub-segment, receive the second sub-segment, the second sub-segment comprising a second set of one or more data units and a second header including data indicative of locations of the data units within the second sub-segment. The device is also configured to process at least a portion of the segment after receiving the first sub-segment and the second sub-segment.

Network streaming of coded video data

Methods provide mechanisms 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 files to be broadcast to applications or services requesting the files.

File delivery over a broadcast network using file system abstraction, broadcast schedule messages and selective reception

In one example, a device includes a plurality of interfaces, wherein each of the interfaces is communicatively coupled to a respective one of a plurality of sources, a stream management unit configured to select, using a manifest file for multimedia content, one of a plurality of representations from which to retrieve multimedia data of the multimedia content, wherein the manifest file includes information indicative of the plurality of representations of the multimedia content, wherein the plurality of representations includes the selected representation, wherein multimedia data for the representations is available from the plurality of sources, and wherein the stream management unit is configured to select one of the sources from which to retrieve multimedia data for the selected representation, and a source component configured to retrieve multimedia data for the selected representation from the selected source via the one of the interfaces that is communicatively coupled to the selected source.

Streaming of multimedia data from multiple sources

Methods, devices and systems for delivering broadcast data to client devices that do not support receiving broadcast transmissions. In an embodiment, a gateway device may be configured to receive a manifest file and related data segments via a first type of network protocol, such as LTE broadcasts. The manifest file may include data defining network addresses for one or more network resources, and may be modified to include a network address of a proxy server for the network resources. The proxy server may be configured to accept requests for data segments from client devices conforming to a second type of network protocol different from the first protocol, such as unicast. In an embodiment, the gateway device may transmit broadcast data for storage in a cache or alternatively a separate storage location accessible to the proxy server. The proxy server may be included in the gateway device or client devices.

Enabling devices without native broadcast capability to access and/or receive broadcast data in an efficient manner

The systems, methods, and devices of the various embodiments enable elastic response times to file requests by a server. In this manner, the server may account for unpredictable delay in object/segment availability and reduce the frequency that error messages (e.g., 404 error messages) are returned in response to file requests when file unavailability is temporary and due to network delays.

Elastic response time to hypertext transfer protocol (HTTP) requests

A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus is configured to monitor for a notification of MCCH information change associated with an MBSFN area without having previously performed an MCCH information acquisition procedure to acquire MCCH information in the MBSFN area. Furthermore, the apparatus is configured to acquire the MCCH information while monitoring for the notification of the MCCH information change that indicates a change of MCCH information.

Method and an apparatus to optimize monitoring for a new EMBMS session in LTE networks

A method for cell reselection by a wireless communication device is described. The method includes camping on a serving cell in idle mode. A neighbor cell is detected. A serving cell rank is computed for the serving cell. A neighbor cell rank is computed for the neighbor cell based on multimedia broadcast multicast service metrics. Cell reselection is determined based on the serving cell rank and the neighbor cell rank.

Cell reselection based on multimedia broadcast multicast service (MBMS) metrics

In one example, a device includes one or more processors configured to determine that data for at least a portion of a segment of media data has been lost after a remaining portion of the segment has been received via a network transmission in accordance with dynamic adaptive streaming over HTTP (DASH), based on the determination, prior to decoding the media data, add default data to the segment to replace the data that has been determined to be lost to form a replacement segment, and output media data of the replacement segment.

Replacing lost media data for network streaming

Techniques are provided for reducing delay during streaming transmissions. For example, a method may include receiving a stream of data segments. The method may include establishing a first group of segments based on the data segments, and generating a first table of information. The method may include transmitting the first table and the first group of segments, and establishing a second group of segments based on the data segments, the second group of segments including a partial overlap of data segments included in the first group of segments. The method may include generating a second table of information, and transmitting the second table and a collection of segments that includes data segments from the second group that were not part of the first group.
