Distribution Network What is a Distribution Network A distribution network is an interconnected group of storage facilities and transportation systems that receive inventories of goods and then deliver them to customers. It is an intermediate point to get products from the manufacturer to the end customer, either directly or through a retail network.

Interactive entertainment system for presenting supplemental interactive content together with continuous video programs

An interactive entertainment system enables presentation of supplemental interactive content along side traditional broadcast video programs, such as television shows and movies. The programs are broadcast in a conventional manner. The supplemental content is supplied as part of the same program signal over the broadcast network, or separately over another distribution network. A viewer computing unit is located at the viewer's home to present the program and supplemental content to a viewer. When the viewer tunes to a particular channel, the viewer computing unit consults an electronic programming guide (EPG) to determine if the present program carried on the channel is interactive. If it is, the viewer computing unit launches a browser. The browser uses a target specification stored in the EPG to activate a target resource containing the supplemental content for enhancing the broadcast program. The target resource contains display layout instructions prescribing how the supplemental content and the video content program are to appear in relation to one another when displayed. When the data from the target resource is downloaded, the viewer computing unit is responsive to the layout instructions obtained from the target resource to display the supplemental content concurrently with the video content program. Embedding the layout instructions in the supplemental content advantageously places control of the presentation to the content developers. The developers are free to arrange the data and video in any manner they choose.

Broadband access transmission network integrating the functions of electric power network, telecommunication network, tv network and internet

A broadband access transmission network integrating the functions of electric power network, communication network, TV network and Internet relates to network transmission. It includes a broadband transmission network of 10 KV power distribution network and a broadband transmission network of low-voltage power distribution network. These two transmission networks are connected via distribution transformers and optical fiber connectors. The broadband transmission network of 10 KV power distribution network is composed of optical compound power lines, wires, transformer substations, machine rooms, taps, insulating jackets, insulating waterproofing outer jackets and optical fiber connectors. The broadband transmission network of low-voltage power distribution network is composed of optical compound power lines, coaxial cable compound power lines, taps, insulating jackets, optical access points, distributors, modems and two-way amplifiers. The invention can perform high-speed broadband communication and power transmission on the same compound wires. It utilizes the existing power network sufficiently and prevents the cost of rebuilding the communication network, cable TV network and Internet, and can simultaneously perform building, operating, maintaining and managing of these networks.

System and method for locating a closest server in response to a client domain name request

A scalable system and method for locating a closest server in response to a client request via an interactive distribution network, such as the Internet, are provided. A closest content server is defined as having the least round trip time for responding to a client request. The system including a plurality of content servers; and a local server in communication with a plurality of clients, the local server acting as a proxy for communicating client requests from clients to a redirection server. Client network distance and load information is periodically collected at each content server in the network from clients communicating with each of the respective content servers. The redirection server periodically aggregates the network distance and load information from each content server to create client clusters from both current and previously aggregated network distance and load information. Each client cluster represents a division or partition of the total IP address space. Each client cluster is then mapped (paired) to one or more content servers in the network. The mapping or pairing is then utilized to respond to client DN requests received from any client in the network. Another aspect of the invention involves considering the respective capacities of the content servers in the network. A selection probability is assigned to each content server/domain index pair to prevent the repeated selection of the content server having lowest round trip time thereby overloading that server's service capacity. The selection probabilities assigned to each content server effect a load balancing to prevent overloading. Another aspect of the invention involves collecting the distance and load information without incurring any overhead cost by passively collecting TCP information as it is transmitted from clients in communication with content servers in the course of normal communications.

Remotely accessible power controller for building lighting

A remotely accessible power controller communicates power reduction command signals by power line carrier (PLC) signaling over existing AC power distribution conductors for automatically disconnecting building lighting loads. Turn-off command signals from a local or remote controller automatically disconnect building lighting loads according to a time-of-day schedule to comply with mandated energy consumption codes applicable to the automatic shutoff of electrical lighting. Load shedding (selective turn off and/or dimming) command signals transmitted from public or private utility companies automatically disconnect or reduce building lighting loads in accordance with load curtailment agreements to limit total connected power consumption below an agreed level. The power controller is connected by a minimum amount of retrofit wiring into an existing end-user alternating current power distribution network, for example, a building power distribution network having AC power conductors that service multiple lighting loads interconnected in one or more power phase groups. Each dimming lighting load is equipped with an addressable dimming module for decoding and executing dimming and turn-on and turn-off power reduction commands. Fluorescent lamps are equipped with addressable electronic dimming ballasts.

System for providing services of event-driven service-oriented internet of things and working method thereof

The invention provides a system for providing services of an event-driven service-oriented internet of things and a working method of the system. The system is composed of a plurality of parts of an internet of things service system, an access agent, a unified message distribution network based on a publish-subscribe mechanism, a complex event processing engine, a resource descriptive model base and a sensor system. The system and the working method solve the problems that an existing system for providing the services of the internet of things can not process large-scale sensing information in a distributed mode, events in a physical world can not be processed, effective cross-business-domain and cross-organization coordination is difficult to achieve by different enterprise business processes. According to the system, sensing information is effectively distributed in the open and distributed computing environment, various pieces of sensing information can be conveniently and quickly distributed as required among different internet of things heterogeneous service systems, event-driven cross-business-domain and cross-organization service dynamic coordination is achieved, time, space and control flow uncoupled network services are provided, and quick response to change of the physical world can be flexibly and dynamically achieved in real time.
