摘要： In general, this disclosure describes techniques for exchanging information between a plurality of encoder modules and a multiplex module to combine segments of data from the encoder modules with an improved overall quality. In particular, the encoder modules associate their respective segments of data with quality and rate information and send at least the quality and rate information associated with the segments of data to the multiplex module. The multiplex module analyzes the quality and rate information to determine whether the segments of data that encoder modules desire to include in the current superframe fit within the available bandwidth of a transmission channel. If the multiplex module determines the plurality of segments of data do not fit within the available bandwidth, the multiplex module selects one or more of the segments to be resized based on the quality and rate information received from the encoder modules.

摘要： Embodiments relate to systems and methods for delivering auxiliary data to a wireless or other device. Content, such as audio, video or textual content, can be hosted by a server for delivery to the device. The content can have associated resources, for example icons, barkers, intros, and outros that are associated with television programming or other media content. A metadata document can describe the set of resources or other auxiliary data associated with a service, channel or content by indicating a resource descriptor, and a URL or other associated resource locator information. The metadata document can be encoded in XML or other formats. The device can locate resources that are intended to be delivered with selected content, since links to the resources are integrated in the metadata document. From the resource descriptor, the device can also identify how a particular resource should be utilized for the service, channel or content.

摘要： Methods and apparatus for communication of notifications are disclosed. A disclosed method for communicating notifications from a server to a device includes sending a primary message including data indicating notification status information; and sending notification messages apart from the primary message addressed to specific groups of devices. Similarly, another disclosed method for obtaining notifications in a device from a server includes monitoring the primary message including current notification status information, comparing the current notification information status information with a previous notification status information to determine if a change in notification status information has occurred, and obtaining addressed notification information when a change in the notification status information has been determined. By using a primary message with abbreviated information to communicate whether changes to notification information have occurred without the need for further processing and/or addressed notification messages, system resources can be conserved. Corresponding apparatus are also disclosed.

摘要： Embodiments enable mobile multimedia receiver devices to receive emergency alert messages from forward link only broadcast networks. Alert messages may be organized in alert sessions identified by an alert session ID. Alert record information may be included in the overhead information symbol (OIS) channel including the session ID and information enabling a receiver device to obtain an alert data message from an alert session in a multicast logic channel. The alert announcement may also be included in the service flow MLCs as an embedded OIS in a first superframe. The alert record may include the number of alert data packets the alert session so receiving devices can determine when they have received all data packets associated with a particular alert. By storing the alert session identifier in memory, receiving devices can ignore subsequent broadcasts of the same alert, thereby enabling them to conserve battery power.
摘要翻译：实施例使得移动多媒体接收机设备能够从仅从前向链路广播网络接收紧急警报消息。警报消息可以组织在由警报会话ID标识的警报会话中。警报记录信息可以被包括在包括会话ID的开销信息符号（OIS）信道中，并且使得接收机设备能够从组播逻辑信道中的警报会话获得警报数据消息的信息。警报通知也可以被包括在作为第一超帧中的嵌入式OIS的服务流MLC中。警报记录可以包括警报会话的数量，因此接收设备可以确定何时接收到与特定警报相关联的所有数据分组。通过将警报会话标识符存储在存储器中，接收设备可以忽略相同警报的后续广播，从而使得它们能够节省电池电力。

摘要： A multi-radio device, such as User Equipment (UE), may experience coexistence issues among various ones of its constituent radio devices that operate at the same time. Various aspects of the disclosure provide techniques to mitigate coexistence issues in multi-radio devices, where significant in-device coexistence problems can exist. In particular, a method for coexistence of multi-radio devices is described. The method includes identifying, at an upper layer of a multi-radio UE, a type of incoming broadcast stream data. The method further includes determining a coexistence policy for operation of communication resources within the multi-radio UE based on the type of the incoming broadcast stream data. The method also includes arbitrating, at a lower layer of the multi-radio UE, between the communication resources based on the coexistence policy.
