    • A packetized streaming media delivery network carries many “streams” of differing media content. They often are from multiple sources and of different media types. The invention consists of a scalable hardware and/or software computing element resolving the network traffic into its individual streams for focused, simultaneous, and continuous real-time monitoring and analysis. The monitoring and analysis consists of delay factor and media loss rate which measure the cumulative jitter of the streaming media within the delivery network and the condition of the media payload. These measurements form a powerful picture of network problem awareness and resolution. The delay factor objectively indicates the contribution of the network devices in the streams' path, allowing for both problem prediction and indication. In one example, tapping a packetized network at various locations allows for correlation of the same-stream performance at various network points to pinpoint the source(s) of the impairment(s).
    • 分组化流媒体传送网络携带许多不同媒体内容的“流”。 它们通常来自多个来源和不同的媒体类型。 本发明包括可扩展的硬件和/或软件计算元件,将网络流量解析成其各个流,用于聚焦,同时和连续的实时监测和分析。 监测和分析包括延迟因子和媒体丢失率,其测量传送网络内的流媒体的累积抖动和媒体有效载荷的状况。 这些测量形成了网络问题意识和解决方案的强大图景。 延迟因子客观地指示网络设备在流的路径中的贡献,允许问题预测和指示。 在一个示例中,在不同位置点击分组化网络允许在不同网络点处的相同流性能的相关性,以确定损害的来源。

    • Streaming media network parameters are measured using an electronic system and displayed directly to a user or transmitted via an electronic interface such as an existing system network conduit (i.e. Ethernet, USB, or other packet-based architectures), either in or out-of-band. A scalable hardware and/or software compute engine filters and reduces network parameters to simplify tracking the instantaneous and long term streaming media performance of the network. Hence, the entire set of active media streams is continuously monitored concurrently, thereby providing the ability to detect impairments as well as predict impending impairments. The prediction of impairments gives rise to the ability to protect the end-user of the streaming media from experiencing any impairments. In one example, an existing packetized network conduit containing streaming media is tapped to concurrently and objectively analyze the streaming media streams, producing statistics (such as delay factor and media loss rate) and alarm-type events according to predetermined rules. Tapping the existing packetized network in multiple points provides comparison points and assists in pinpointing the source(s) of the impairment(s).
    • 使用电子系统测量流媒体网络参数,并直接显示给用户或通过诸如现有系统网络管道(即,以太网,USB或其他基于分组的架构)等电子接口进行传输, 带。 可扩展的硬件和/或软件计算引擎过滤和减少网络参数,以简化跟踪网络的瞬时和长期流媒体性能。 因此,整套活动媒体流被同时连续监测,从而提供检测损伤以及预测即将发生的损伤的能力。 损伤的预测导致保护流媒体的最终用户免受任何损害的能力。 在一个示例中,利用包含流媒体的现有分包网络管道,以同时并客观地分析流媒体流,根据预定规则产生统计(例如延迟因子和媒体丢失率)以及报警类型事件。 在多个点攻击现有的分组网络提供比较点,并帮助精确确定损害的来源。
