Abstract: Interactive internet activities are a very popular means for gathering information for business, personal, medical, entertainment and other purposes. Most internet interaction is asymmetrical in nature in that a client's requests for information are much smaller (in data size) than the resulting information delivered by the server. Although the client/internet link is inherently asymmetrical, there remains a great deal of interaction and overhead required between the client and the server that increases the bandwidth needs for the client's upstream request channel. There are many advantages to reducing this upstream traffic volume and thereby making the internet interaction even more asymmetrical. Such compression of request data could allow more clients to utilize a single upstream data path instead of separate paths.

Abstract translation: 互动互联网活动是收集商业，个人，医疗，娱乐和其他用途信息的非常受欢迎的手段。 大多数互联网互动本质上是不对称的，因为客户的信息请求比服务器提供的信息要小得多（数据大小）。 虽然客户端/互联网链路本质上是不对称的，但客户端和服务器之间仍然需要大量的交互和开销，从而增加客户端上行请求信道的带宽需求。 减少上游流量有很多优点，从而使互联网互动更加不对称。 请求数据的这种压缩可以允许更多的客户端利用单个上游数据路径而不是单独的路径。

Abstract: Most cable television systems in the United States (over 75% as of this application) are structured for one-way only service between the cable headend and the user. With more and more services being introduced that require a two-way connection with the user (e.g. impulse-pay-per-view, home shopping, Internet access), it has become necessary for more and more cable systems to upgrade to a two-way capability at considerable cost and over a fairly long period of time. The typical short-term solution to the lack of two-way capability is to send request backlinks over he user's telephone line. The problem with this solution is that when used, it ties up the telephone line and requires an additional telephone connection to be located near the cable set-top-box or modem. A more practical solution is the hub centered backhaul invention described herein. With this invention, users can operate their cable systems as if they were two-way systems, with all available interactive capabilities available. The request channel, however, will be intercepted at a central location between multiple users, and returned to the cable headend via an alternate communication path. The backlink request will be intercepted at a location in the cable distribution prior to hardware that precludes two-way transmissions, such as amplifiers.

Abstract: An information broadcast system having a broadband broadcast system selected from cable and satellite for broadcasting requested information from a selected information source, including the Internet, to one or more selected subscriber stations includes an independent backhaul channel for communicating information request signals from a subscriber station to one or more central processing stations. The system includes a data broadcast station for transmitting requested data from the selected data source and central station via the data broadcast station to the one or more selected subscriber stations. The high-data rate broadcast station forwards requested data from a data source to the data broadcast station. A backhaul satellite communication system, independent of the broadband broadcast system, has a backhaul satellite ground terminal for coupling information request signals from backhaul satellite communication system to high data broadcast station terminal. Each subscriber station has a broadband broadcast receiver for receiving requested information broadcast by the high data rate broadcast and a satellite antenna for transmitting backhaul request signals to the backhaul satellite.
