    摘要： A method and apparatus for communicating streaming data, such as audio and video streams, isochronously over a network. The invention may be utilized with power-line communication (50) networks or other IP-based networks. Hardware (82) is configured for packetizing the streaming data, such as MPEG streaming data, which is communicated at the IP physical layer within a contention-free period within each communication cycle (32a and 32b). A reservation mechanism utilizes back-offs to allow a single transmitter to reserve a slot for isochronous communication of a given stream of data. A processing element handles packetizing only for asynchronous communication of data within the remaining portion of each communication cycle which is referred to as a contention period (34), as a number of transmitters may vie for communication during that interval. Addressing for the isochronous communication is performed with MAC addressing instead of IP addressing. Existing IP stack and protocols can be reused for upper layer control mechanisms.

    摘要： A system and method of providing distributed video and/or audio communication over a network, such as a power-line communications (PLC) network. By way of example, the network is divided into periodic cycles wherein each cycle comprises a number of time slots. The timing of the cycles is determined by a cycle master that assumes the position when it desires to send a transmission and is unable to detect valid cycles on the network. A portion of each cycle is reserved for the transmission of asynchronous data, the remainder being utilized for isochronous streams. Before transmitting a new stream a transmitter wins one or more open slots by arbitration, wherein the winner is selected based on the priority of the stream to be sent. Transmitters may obtain extra slots to improve quality, integrity, or security of the stream. The mechanisms of the invention are compatible with legacy CDMA devices.

    摘要翻译： 一种通过诸如电力线通信（PLC）网络的网络提供分布式视频和/或音频通信的系统和方法。 作为示例，网络被分成周期性周期，其中每个周期包括多个时隙。 周期的定时由周期主机确定，该周期主机在需要发送传输时假定位置，并且无法检测到网络上的有效周期。 每个周期的一部分被保留用于传输异步数据，其余部分用于等时流。 在发送新流之前，发射机通过仲裁赢得一个或多个开放时隙，其中基于要发送的流的优先级来选择获胜者。 发射机可以获得额外的时隙，以提高流的质量，完整性或安全性。 本发明的机制与传统CDMA设备兼容。

    摘要： System and method for facilitating the positioning of an antenna adaptable for receiving transmitted signals wherein antenna alignment values obtained from equalizer tap-weight values are displayed so as to provide an indication as to whether or not the antenna is properly aligned. Such antenna alignment values may change gradually as the antenna is rotated or moved. As a result, an installer can easily position or point an antenna in the direction of the transmission site.
