Abstract: Content streams, such as video streams, may be seamlessly provided as both multicast and unicast transmissions. For example, in one implementation, a mobile device may receive a request, from a user of the mobile device, to play streaming content at the mobile device. The mobile device may receive, from a wireless network, and using multicast techniques, a sequence of content segments that correspond to the requested streaming content, and determine when a content segment is missing from the sequence of content segments. The mobile device may request, in response to the determination of the missing content segment, the missing content segment, from the wireless network, using unicast techniques; and insert the received missing content segment into the sequence of content segments to obtain the sequence of content segments as a sequence that includes content segments received using both multicast and unicast techniques.

Abstract translation: 诸如视频流的内容流可以无缝地提供为多播和单播传输。 例如，在一个实现中，移动设备可以从移动设备的用户接收到在移动设备处播放流内容的请求。 移动设备可以从无线网络并且使用多播技术来接收与所请求的流式传输内容对应的内容片段序列，并且从内容片段的序列中确定内容段何时丢失。 移动设备可以响应于丢失内容段的确定，从无线网络请求使用单播技术的丢失内容段; 并将接收到的缺少的内容片段插入到内容段的序列中，以获得内容段的序列作为包括使用多播和单播技术接收的内容片段的序列。
