摘要： Methods and apparatus for service acquisition in a broadcast system. In an aspect, a method includes detecting whether a loss of service has occurred, and initiating acquisition attempts during an aggressive acquisition phase if a loss of service has occurred, wherein a backoff time interval between successive acquisition attempts is constant or increased, and wherein the aggressive acquisition phase ends when service acquisition is achieved or a selected number of acquisition attempts have been performed. An apparatus includes interface logic configured to detect whether a loss of service has occurred, and processing logic configured to initiate acquisition attempts during an aggressive acquisition phase if a loss of service has occurred, wherein a backoff time interval between successive acquisition attempts is constant or increased, and wherein the aggressive acquisition phase ends when service acquisition is achieved or a selected number of acquisition attempts have been performed.

摘要： Techniques are provided for receiving one or more representations of content wirelessly. The method may involve receiving a media presentation description (MPD) that includes parameters for reception of data segments for multiple representations of content via broadcast transmission and unicast transmission (2312). The method may involve determining whether the broadcast transmission or the unicast transmission is appropriate for reception of the data segments (2314), and selecting a given representation from among the multiple representations of the content based on a criteria of the mobile entity (2316). The method may involve receiving the data segments for the given representation based at least in part on the parameters for the determined one of the broadcast transmission and the unicast transmission (2318).
摘要翻译：提供了用于以无线方式接收内容的一个或多个表示的技术。该方法可以包括接收媒体呈现描述（MPD），该媒体呈现描述包括用于通过广播传输和单播传输（2312）接收用于内容的多个表示的数据段的参数。该方法可以包括确定广播传输或单播传输是否适合于接收数据段（2314），以及基于移动实体（2316）的标准从内容的多个表示中选择给定表示。该方法可以包括至少部分地基于广播传输和单播传输中确定的一个的参数来接收针对给定表示的数据段（2318）。

摘要： Diversity enhancement for multiple carrier systems is disclosed which includes generation of a multiplexed multicarrier radio frequency (RF) signal having N carriers organized to be accessed at a rate of one carrier access per multicast channel (MCH) scheduling period (MSP) per carrier of the N carriers, thereby requiring N accesses per MSP duration across the N carriers. The method may also include the base station transmitting the RF signal to a user equipment (UE). In other aspects, the diversity enhancements include the UE receiving a multiplexed multicarrier RF signal having N carriers. The UE may access the N carriers by performing one carrier access per MSP per carrier of the N carriers, thereby performing N accesses per MSP duration across the N carriers.

摘要： Data objects are delivered over a packet switched network and receivers receive encoded symbols, such as repair symbols, broadcast or multicast, with sufficient information to form requests for additional symbols as needed based on what source symbols or sub-symbols are needed or missing. The requests can be made in a unicast or request fashion. Requesting and broadcasting might be done by different entities. A broadcast server can generate and store repair symbols while a source server can store content in source form. A request can be a unicast HTTP byte-range request, such as a URL, starting position and length. Requests might be aligned with starting positions of files. A receiver can calculate starting and ending byte positions of symbols or sub-symbols in a file and get indications that conventional HTTP servers are usable for file repair. Repair servers can request broadcast of repair data when byte-range requests from multiple receivers overlap.
摘要翻译：数据对象通过分组交换网络传送，并且接收机接收具有足够信息的编码符号，如修复符号，广播或多播，以根据需要或根据需要或缺少哪些源符号来形成对附加符号的请求。请求可以以单播或请求方式进行。请求和广播可能由不同的实体完成。广播服务器可以生成和存储修复符号，而源服务器可以以源形式存储内容。请求可以是单播HTTP字节范围请求，例如URL，起始位置和长度。请求可能与文件的起始位置一致。接收器可以计算文件中符号或子符号的开始和结束字节位置，并获得常规HTTP服务器可用于文件修复的指示。当来自多个接收器的字节范围请求重叠时，修复服务器可以请求广播修复数据。
