    • A system to provide a multipoint processing terminal and a multicast bridging terminal to provide mixing, switching, and other processing of media streams under the control of H.323 components. Application Programming Interfaces defined for the multipoint processing terminal provide a multipoint control unit with the capability to change the default behavior of the multipoint processing terminal by allowing the multipoint control unit to control the routing audio and video streams in the multipoint processing terminal and control the media formats in a multipoint conference. Multipoint processing acceleration functionality is provided by providing interfaces to allow hardware accelerated implementations of multipoint processing terminals. The multicast bridging terminals enables clients using one type of control signaling and media streaming to join other conferences using different types of control signaling and media streaming by receiving audio or video data from an incoming media stream and performing any processing necessary to transform the media stream from the incoming stream data format to the outgoing stream data format.
    • 一种提供多点处理终端和组播桥接终端的系统,用于在H.323组件的控制下提供媒体流的混合,切换和其他处理。 应用程序编程为多点处理终端定义的接口提供多点控制单元,具有通过允许多点控制单元控制多点处理终端中的路由音频和视频流并控制媒体的能力来改变多点处理终端的默认行为的能力 多点会议中的格式。 通过提供允许多点处理终端的硬件加速实现的接口来提供多点处理加速功能。 组播桥接终端使得客户端能够使用一种类型的控制信令和媒体流来使用不同类型的控制信令和媒体流来连接其他会议,通过从传入的媒体流接收音频或视频数据,并执行将媒体流从 输入流数据格式为输出流数据格式。

    • A sequential access memory structure includes an output bus and a plurality of sequential access memories, each of which is connected to the output bus. Each memory includes a memory array having a plurality of sequentially readable memory elements, a carry output for producing a carry signal when reading of the array has been substantially completed, and a carry input for causing reading of the array in response to a carry signal. The carry output of each memory is connected to a carry input of one other downstream memory respectively in a chain arrangement, and the carry signals cause the arrays to be read sequentially onto the output bus. Each memory further comprises a read-write storage connected between the array and the output bus, the storage including a plurality of sections. Data from the array is loaded into one section of the storage while data is being read from another section of the storage onto the output bus. The sections of memory elements in the array comprise half-pages. The storage comprises two sections, each of which has a half-page of memory elements, and the carry output produces the carry signal prior to reading data from a last half-page of the array out of the storage onto the output bus. Data from the last half-page is read onto the output bus while data from a first half-page of an array of a next downstream memory is being loaded into its storage.
    • 顺序访问存储器结构包括输出总线和多个顺序存取存储器,每个存取存储器连接到输出总线。 每个存储器包括具有多个可顺序读取的存储器元件的存储器阵列,当阵列的读取已基本完成时用于产生进位信号的进位输出,以及用于响应于进位信号而引起阵列读取的进位输入。 每个存储器的进位输出分别以链排列连接到另一个下游存储器的进位输入,并且进位信号使得阵列被顺序读取到输出总线上。 每个存储器还包括连接在阵列和输出总线之间的读写存储器,存储器包括多个部分。 来自阵列的数据被加载到存储的一部分中,同时从存储器的另一部分读取数据到输出总线上。 阵列中的内存元素部分包括半页。 存储器包括两个部分,每个部分具有半页存储器元件,并且进位输出在从阵列的最后半页从存储器中读取数据到输出总线之前产生进位信号。 来自上一个半页的数据被读取到输出总线上,而来自下一个下游存储器阵列的前半页的数据被加载到其存储器中。
