摘要： An apparatus (1) for switching real-time media streams of one or multiple sources (Q1, Q2, Q3) to one or multiple sinks (S1, S2, S3) includes one or multiple source ports (QA1, QA2, QA3) for connecting of the one or multiple sources (Q1, Q2, Q3) as well as one or multiple sink ports (SA1, SA2, SA3) for connecting of the one or multiple sinks (S1, S2, S3). The apparatus (1) is adapted to provide a switching sink (SS) and to switch it to a real-time media stream of a first source (Q1). The switching sink (SS) is adapted to receive the real-time media stream of the first source (Q1) in a packet-switched format and to forward the received real-time media stream in a packet-switched format, wherein the packets are provided with a first multi-point destination address (IPMZS) allocated to the switching sink (SS) during forwarding in order to allow for a connecting of the one or multiple sinks (S2) with the real-time media stream of the first source (Q1) forwarded by the switching sink (SS). The switching sink (SS) represents the source of the real-time media stream forwarded by the switching sink (SS) from the “point of view” of the sinks (S1, S2, S3) connected to the apparatus, with which the sinks (S1, S2, S3) can connect through the multi-point destination address (IPMZS).

摘要翻译： 一种用于将一个或多个源（Q1，Q2，Q3）的实时媒体流切换到一个或多个信宿（S1，S2，S3）的装置（1）包括一个或多个源端口（QA1，QA2，QA3），用于 一个或多个源（Q1，Q2，Q3）以及用于连接一个或多个汇（S1，S2，S3）的一个或多个汇入口（SA1，SA2，SA3）的连接。 装置（1）适于提供切换接收器（SS）并将其切换到第一源（Q1）的实时媒体流。 交换接收器（SS）适于以分组交换格式接收第一源（Q1）的实时媒体流，并以分组交换格式转发所接收的实时媒体流，其中分组是 具有在转发期间分配给交换接收器（SS）的第一多点目的地址（IPMZS），以便允许一个或多个接收器（S2）与第一源的实时媒体流的连接（ Q1）由交换接收器（SS）转发。 交换接收器（SS）表示从连接到设备的接收器（S1，S2，S3）的“观察点”由切换接收器（SS）转发的实时媒体流的源， （S1，S2，S3）可以通过多点目的地址（IPMZS）进行连接。
