Media server interconnect architecture

机译:媒体服务器互连架构

摘要

An improved media server interconnect to subscriber terminals is accomplished with a plurality of media servers at a headend where each media server provides one or more programs for distribution to the subscriber terminals. An array of modulators connects a requested media asset, such as a video program or WEB page, from a media server to a requesting subscriber terminal. A connection manager responds to a media asset request from the requesting subscriber terminal and selects a source server to provide the requested media asset and selects a modulator in the array to send the requested media asset from the source server to the requesting subscriber terminal. The array of modulators acts as a two stage switch between the source server and the requesting subscriber terminal. A selected modulator in said array is the switch point in the two stage switch. The connection manager controls a first stage of the switch by selecting the selected modulator to receive the requested media asset from the source server. The requesting subscriber terminal acts as a second stage of the two stage switch also under the control of the connection manager by tuning to the channel frequency of the selected modulator.
