    • Embodiments of systems and methods for efficient broadcasting via random linear packet combining are described. A method for random linear packet combining includes receiving a plurality of data packets from a data source. Additionally, the method may include dividing the plurality of data packets into a plurality of data blocks, and multiplying bits associated with the plurality of data blocks by a set of coefficients to generate a plurality of product values. The method may also include generating an encoded data packet having a plurality of encoded data blocks, wherein generating the encoded data packet comprises linearly combining the plurality of product values for respective data blocks of each of the plurality of data packets into corresponding encoded data blocks of the encoded data packet. Because each encoded data packet includes information about a complete set of data packets, rather than just a subset, less broadcast redundancy may be required.
    • 描述了通过随机线性分组组合进行有效广播的系统和方法的实施例。 随机线性分组组合的方法包括从数据源接收多个数据分组。 另外,该方法可以包括将多个数据分组划分为多个数据块,以及将与多个数据块相关联的比特乘以一系列系数以生成多个乘积值。 该方法还可以包括生成具有多个编码数据块的编码数据分组,其中生成编码数据分组包括将多个数据分组中的每一个的相应数据块的多个乘积值线性组合成相应的编码数据块 编码数据包。 因为每个编码的数据分组包括关于完整的一组数据分组的信息,而不仅仅是一个子集,所以可能需要较少的广播冗余。

    • Systems and methods which provide data communication content delivery through a hybrid network implementation are disclosed. A hybrid network configuration may utilize a broadcast communication technique to deliver large amounts of data communication content to one or more mobile communication device via uni-directional network links and a uni-cast communication technique via bi-directional network links with the one or more mobile communication device to facilitate delivery and utilization of the data communication content. Data content delivery loss recovery techniques implemented according to embodiments of the invention utilize network links of the hybrid network other than or in addition to the uni-directional network links to implement loss recovery techniques such as a hybrid repeat technique, a hybrid retransmission technique, hybrid statistical feedback technique, and/or combinations thereof.
