摘要： A surveillance system configured for communicating with video cameras and other devices connected over a power-line communication network, such as within a residence, or alternatively a commercial building. The system may be manufactured and installed at low cost without the need to route individual cables to each surveillance video camera or device. Bandwidth within the power-line communication network is preferably dynamically allocated to device streams by a server in response to predetermined and event-driven priorities. By way of example, remote communication is supported for allowing remote access to surveillance data and control of the surveillance system. The system may be implemented as a standalone unit or integrated within existing forms of electronics equipment, such as consumer electronics equipment including a television set, a set-top box, or other forms of video-enabled equipment that is adapted for performing power-line network communication.

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 (PLC) networks or other IP-based networks. Hardware 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. 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, 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： In accordance with certain embodiments consistent with the invention, a power line communication (PLC) bridge circuit, consistent with certain embodiments, has a first coupler that couples data signals to and from a main power line circuit. A second coupler couples data signals to and from a branch power line circuit, wherein the branch power line circuit is branched from the main power line circuit. A first communication transceiver is connected to the first coupler for transferring data signals to and from the first coupler. A second communication transceiver is connected to the second coupler for transferring data signals to and from the second coupler. A controller examines data signals from the first transceiver and determines if the data is destined for the second transceiver, so that data that is not destined for the second transceiver is considered local data. The controller also examines data signals from the second transceiver and determines if the data is destined for the first transceiver, so that data that is not destined for the first transceiver is also considered local data. A bridge passes data signals between the first communication transceiver and the second transceiver when the controller determines that the data is not local, and passes data signals between the first communication transceiver and the second communication transceiver when the controller determines that the data is local. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
摘要翻译：根据与本发明一致的某些实施例，与某些实施例一致的电力线通信（PLC）桥接电路具有将数据信号耦合到主电力线电路和从主电力线电路耦合数据信号的第一耦合器。第二耦合器将数据信号耦合到分支电力线电路，其中分支电力线电路从主电力线电路分支。第一通信收发器连接到第一耦合器以将数据信号传送到第一耦合器和从第一耦合器传送数据信号。第二通信收发器连接到第二耦合器以将数据信号传送到第二耦合器和从第二耦合器传送数据信号。控制器检查来自第一收发器的数据信号，并确定数据是否发往第二收发器，使得不用于第二收发器的数据被认为是本地数据。控制器还检查来自第二收发器的数据信号，并确定数据是否发往第一收发器，使得不用于第一收发器的数据也被认为是本地数据。当控制器确定数据不是本地时，桥接器在第一通信收发器和第二收发器之间传递数据信号，并且当控制器确定数据是本地的时，桥接器在第一通信收发器和第二通信收发器之间传递数据信号。该摘要不被认为是限制性的，因为其他实施例可能偏离本摘要中描述的特征。

摘要： To increase bandwidth, a channel, which normally is limited to contention-free transmissions, is used for other purposes during times when it is not needed for contention-free transmissions. Although the channel is located in a contention-free portion of a beacon cycle, supplemental uses of this channel include the contention-based transmission of data that normally would be sent during a contention portion of the cycle. These transmissions include those made under the CSMA protocol.
