摘要： PROBLEM TO BE SOLVED: To provide a mechanism which does not charge when receiving notice of reception of an unviewable content from a receiver since a transmission side is basically unable to know whether a sent packet has been delivered to an opposite side through UDP (User Datagram Protocol) though UDP is generally used in large-scale stream distribution service such as IP broadcasting in order for distribution efficiency of a content distributing server. SOLUTION: When the content is distributed on a streaming basis using the communication protocol through which whether the sent data packet has been received by the communication partner is unknown, content distribution processing is performed by monitoring the number of loss packets, the occurrence state of a buffer overflow, etc., on a receiver side, and judging that the content is too poor to view and then not charging for the content distribution service when a certain reference value is exceeded. Consequently, it can be guaranteed that the distribution of the stream content which is not suitable to a service user is not charged for. COPYRIGHT: (C)2008,JPO&INPIT
摘要翻译：要解决的问题：提供一种从接收机接收到不可观看内容的接收通知时不收取的机制，因为发送方基本上不知道发送的分组是否已经通过UDP被传送到相对侧（用户数据报协议）虽然UDP通常用于诸如IP广播的大规模流分发服务中，以便分发服务器的分发效率。解决方案：当使用通信协议通过通信协议分发内容是否已经被通信对方接收到的发送的数据分组是未知的，通过监视丢失分组的数量来执行内容分发处理，发生在接收机侧发生缓冲器溢出状态等，并且当超过某个参考值时，判断内容太差以便不能查看内容分发服务，而不对内容分发服务进行计费。因此，可以保证不对服务用户不适合的流内容的分发。版权所有（C）2008，JPO＆INPIT
