Abstract: Error correction coding for streaming communication is provided. A streaming problem is modeled as a non-multicast network problem with a nested receiver structure. Each packet in the streaming problem corresponds to a link, and each deadline in the streaming problem corresponds to a receiver in the non-multicast network problem. For the non-multicast network problem, content to be transmitted in multiple packets to multiple receivers is obtained. Each of the receivers is required to decode specific independent messages from the content, at given time steps, and has access to a subset of the content received by another receiver. The content is allocated into multiple packets to be transmitted on multiple links. No coding occurs across information demanded by different receivers. A capacity region defines a set of information rate vectors that can be communicated to the receivers successfully. A rate vector is successfully communicated if it complies with various inequalities.

Abstract translation: 提供了流媒体通信的纠错编码。 流问题被建模为具有嵌套接收机结构的非多播网络问题。 流式传输问题中的每个数据包都对应一个链接，并且流媒体问题中的每个截止日期对应于非多播网络问题中的接收者。 对于非组播网络问题，可以获得要以多个分组发送到多个接收机的内容。 需要每个接收机在给定的时间步骤从内容中解码特定的独立消息，并且可以访问由另一接收机接收的内容的子集。 内容被分配到多个分组中以在多个链路上传输。 不同接收机所要求的信息不发生编码。 容量区域定义可以成功地传送到接收器的一组信息速率向量。 如果符合各种不平等的情况，速率向量成功传达。
