The invention is directed to techniques for maintaining a map of node relationships for a network of nodes (e.g., network of computers). In one example, the map of node relationships represents relationships overlaying and typically different from the network of physical connections among the nodes. Each child node periodically checks in with its parent nodes, and the parent nodes can thus determine when a child node has terminated a relationship with the parent or created a new relationship with a new parent. Changes in relationships propagate upward through the network of nodes so that each node maintains a map of the relationships among the descendants of that node. A root node receives the propagated change relationship information and maintains a map of the entire network and valid pathways through the network. The root node can use the map when responding to a request from a client to receive services from a node in the network and redirects the client to attach to a node in the network that has a valid path to the root node. The root node can then broadcast data (e.g. a stream of video data) throughout the network, which is received by all the clients attached to nodes in the network.

A transmitter is provided having transmission methods that minimize the power needed to ensure reliable reception in a coverage area. In one aspect, data that requires re-transmission as acknowledged mode data is re-transmitted when the power level of the transmission link is higher than a pre-determined level set for reliable reception.

More reliable satellite television reception in moisture conditions is provided by recognizing the critical relationship between satellite signal transmissivity and the effects of superhydrophobocity. Instead of trying to use a hydrophobic or superhydrophobic coating or material to shed water from a satellite antenna, superhydrophobic materials and coatings are strategically utilized to minimize the impact of water on the transmissivity of the satellite signal through transmissive surfaces in the antenna system. In a preferred embodiment, an exterior surface of a feed horn cover is coated with a superhydrophobic material to maintain a more consistent satellite signal reception. In an alternate embodiment, an exterior surface of a dome covering a small dish DBS satellite television antenna system is coated with a superhydrophobic material to minimize the overall satellite signal loss during moisture conditions so as to permit a dome to be effectively used over a small dish DBS satellite television antenna system.

A communication method of one-line bus comprises a data sending step and a data receiving step. The data sending comprises the following steps: (1) sending an initial signal: a sending device draws bus level down; (2) sending the data: the data is sent, and whether a bit signal is 1 or 0 is represented by the duty ratio of a high level and a low level in each bit of the data; and (3) receiving a response signal: if the response signal is received, the data sending is successful, otherwise the data sending fails. The data receiving comprises the following steps: (1) receiving the initial signal: a receiving device judges whether a signal is the initial signal, and receives the signal if yes; (2) receiving data: the duty ratio of the high level and the low level in each bit of the data is judged to determine whether the bit is signal 1 or 0; and (3) sending an acknowledgement signal: after the data is received, the acknowledgement signal is sent. After the data sending and the data receiving are over, the high level is disposed to the bus to release the bus. The method determines the received data by computing the duty ratio and verifies the duty ratio, thus the anti-interference capacity is strong.

A control message communication mechanism for use in a broadband transceiver system that includes multiple digital signal processors for performing real time signal processing tasks. One of the digital signal processor (DSPs) is designated as a master DSP. The remainder of the DSPs are arranged in rows and columns to provide a two-dimensional array.

A scheme for improved throughput in a communication system by combining non-time-coincident macro diversity with timeslot re-use, enabling the benefits of macro diversity to be achieved without substantial impact on the receiver architecture or design. This allows for a significant increase in throughput when transmitting to users close to a cell edge, whilst avoiding any significant increase in UE receiver (900) complexity. It is also extremely beneficial to broadcast services in cellular-like deployments in which large increases in broadcast rate may be achieved whilst maintaining the same broadcast coverage. Preferably, fully non-time-coincident macro-diversity is utilised, but partially-non-time-coincident macro diversity may alternatively be utilised. Preferably, timeslot re-use of order N with macro diversity of order M, where M and N are equal, is utilised, although different values of N and M may alternatively be utilised.
