摘要： Real-time video can be efficiently and reliably streamed over wireless networks by fountain encoding a stream of video packets at the frame-level. Specifically, deep packet inspection may be performed on the stream of video packets to identify a set of video packets corresponding to an intra-coded frame (I-frame). The set of video packet may then be fountain encoded together as a data segment to produce a set of fountain encoded packets corresponding to the I-frame. Video packets corresponding to other frames (e.g., P-frames, etc.) may also be encoded on a frame-by-frame basis. This may allow a user equipment (UE) to begin displaying earlier frames in a group of pictures (GoP) while fountain encoded packets for subsequent frames are still being received, thereby reducing latency and improving the overall user experience.
摘要翻译：通过在帧级编码视频数据包流，可以通过无线网络高效可靠地流式传输视频。具体地，可以对视频分组流执行深度分组检查，以识别与帧内编码帧（I帧）对应的一组视频分组。然后，该组视频分组可以一起作为数据段进行喷泉编码，以产生与I帧对应的一组墨斗编码分组。对应于其他帧（例如，P帧等）的视频分组也可以逐帧编码。这可以允许用户设备（UE）开始在一组图像（GoP）中显示较早的帧，而用于后续帧的喷泉编码分组仍然被接收，从而减少等待时间并改善整体用户体验。

摘要： Methods and apparatus for managing data content among in-network caches of a communication network are provided. In some embodiments, multiple registers are maintained for indexing cached data content. Different data content is indexed in different registers based on parameters such as popularity or content freshness. Customized popularity estimators can be applied to each register, and data content may be indexed by different registers as parameters change. Less popular content can be removed from caches as required. In some embodiments, caches can be grouped into clusters, and deletion of data content from a cache may be modified or inhibited if the cluster still requires a copy of that data content. Data content can be moved between caches of a cluster based on popularity.
