Abstract: Apparatus and method of achieving diversity in reception of plural digital broadcast signals. A stream of a complete set of code bits is generated from one or more sources of data bits. A first Critical Subset of code bits is chosen or selected for a first channel (e.g. a specified puncturing pattern is applied to the stream of a complete set of code sets). A second (e.g. alternative) Critical Subset of code bits is chosen or selected for a second channel (e.g. a second or alternative puncturing pattern is chosen for the second channel). Further alternative Critical Subsets may be chosen for any additional channels. All the channels are transmitters, some can incorporate time delay to achieve temporal diversity. Moreover, the order of transmitting the code bits on each channel can be it different (for example, the interleaving depths can be different). At the receiver, the stream of Critical Subsets of code bits for all of the channels are simultaneously received and a reconstruction of a complete set of code bits accomplished and the reconstructed code and may be inserted into a single Viterbi decoder. Various weighting functions and reconstruction algorithms are disclosed.

Abstract: A communication system (10) using hierarchical modulation includes at least one satellite (12 & 13) transmitting a data stream and a hierarchical modulated data stream, and at least one terrestrial station (16) transmitting the data stream and the hierarchical modulated data stream. The communication system can further include at least one receiver (18) for demodulating and combining the data stream from at least one satellite and from at least one terrestrial station and for hierarchically demodulating and combining the hierarchical modulated data stream from at least one satellite and the hierarchical modulated data stream from at least one terrestrial station. The terrestrial station can be a terrestrial repeater repeating the data stream and the hierarchical data stream from at least one satellite. The system can also include an uplink (11) having a hierarchical modulator for modulating both the data stream and the hierarchical data stream.

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 translation: 美国大多数有线电视系统（超过75％的应用程序）都是针对有线头端和用户之间的单向服务进行结构化的。 随着越来越多的服务被引入，需要与用户的双向连接（例如，按次付费浏览，家庭购物，互联网接入），越来越多的有线系统已经变得需要升级到双向连接， 相当的成本和相当长的一段时间内的方式能力。 缺乏双向能力的典型的短期解决方案是在用户的电话线上发送请求反向链接。 这个解决方案的问题是，当使用时，它绑定电话线，并需要额外的电话连接位于电缆机顶盒或调制解调器附近。 更实际的解决方案是本文描述的以枢纽为中心的回程发明。 通过本发明，用户可以像他们的双向系统一样操作其有线系统，具有可用的所有可用交互功能。 然而，请求信道将在多个用户之间的中心位置被拦截，并且经由备用通信路径返回到电缆头端。 在排除诸如放大器之类的双向传输的硬件之前，反向链接请求将在电缆分发的位置被拦截。

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.

Abstract: A method is provided for enhancing a legacy satellite digital radio audio service (SDARS) by overlaying a hierarchically modulated data stream on a base layer (legacy) data stream and improving the synchronization of the received signal in which an overlay layer frame is synchronized to a base layer frame. The base layer frame includes additional data that is used to synchronize the receivers to demodulate and decode the overlay layer and the base layer. The additional data is modulated using a technique that aids the receiver in synchronizing the received signal that is different from the overlay layer.

Abstract: A system (100) for combining satellite and terrestrial signals from spatially diverse antennas (102 and 104) includes a tuner (101) and at least first and second analog to digital converters (103, 105) for converting at least two among the plurality of satellite signals and the terrestrial signal to a first digital stream and a second digital stream. A switch arrangement (106, 102 126) selectively switches among the first digital stream and the second digital stream before demodulating the digital streams using a plurality of algorithms (112, 122, 130) that selectively uses respectively demodulated signals of the first digital stream and the second digital stream to control (114, 124, 132) the switch arrangement to provide a plurality of multiplexed signals (161, 162, 163) that are combined (134) to form a combined signal (170). The combined signal can then be forward error corrected (136).

Abstract: A method (500) for timing recovery in an orthogonal frequency division multiplexing (OFDM) system includes the steps of detecting (502) a lack of a synchronization symbol and determining (504) a timing offset from calculating the average group delay across the subcarriers over multiple OFDM symbols. The timing offset is fed back (506) to a demodulator and the symbol timing is adjusted (508) based on the Average Group Delay phasor fed back to the demodulator.
