摘要:
An integrated cable modem and cable television management system. The invention may include a stand alone device, a portable device, or a vehicle adapted device in various embodiments of the invention. The invention allows for two-way communication and interaction between a television service provider and a user of the device. In addition, other various circuitries may reside in the device allowing storage and processing of received signals. The invention allows a device operable to receive different broadcast signals, including analog and digital signals. In addition, the invention allows for download of selectable programming from a cable television server using the device, either offline, streaming, or in real time when online. The invention allows for recording and buffering of received signals. In addition, the invention allows for control of commercials, publications, and content contained within received signals. The invention allows for time compression of such signals as well.
摘要:
Two wireless local area networks exhibiting different characteristics link portable or mobile computer devices. An infrastructure network comprising radio base stations, and at least one portable computer device make up the first wireless network, which communicates using spread spectrum frequency hopping communication. A second local area network supports radio communication between a portable computer and peripheral devices with built-in transceivers. The networks use a reservation access protocol that facilitates frequency hopping synchronization, supports adaptive data rate selection based on communication quality, and prevents interference between the wireless networks. In a premises LAN, an infrastructure network comprises radio base stations and a backbone LAN. A higher-power LAN using frequency hopping comprises the infrastructure network and at least one mobile computing device. A lower-power LAN uses single-frequency spread spectrum communication between a mobile computing device and peripheral devices. A vehicular LAN supports short-range communication between vehicle and portable terminals.
摘要:
A hierarchical communication system, arranged in a spanning tree configuration, is described in which wired and wireless communication networks exhibiting substantially different characteristics are employed in an overall scheme to link portable or mobile computing devices. Copies of data, program code and processing resources are migrated from their source toward requesting destinations based on request frequency, communication link costs and available local storage and/or processing resources. Each appropriately configured network device acts as an active participant in network migration. In addition, portable two-dimensional (2-D) code reading terminals are configured to wirelessly communicate compressed 2-D images toward stationary access servers that identify the code image through decoding and through comparison with a database of images that have previously been decoded and stored.

摘要:
In a store data communications system, multiple data sources having disparate communications standards are connected with respective device interfaces of a multiple device communications controller unit. Multiple protocol controllers are coupled with the respective device interfaces and convert the data from each to a common protocol for transmission via a single telephone line. The interface units preferably can be customized to operate with various data sources, a fiber optic coupler, or a modem, or another controller unit for convenient expansion. The device interfaces preferably have snap-in assembly with the controller unit so that device interfaces customized to different standards can be inserted or replaced at any interface receptacle, the multiple protocol controllers preferably being capable of corresponding re-programming by downloading from a remote station preferably via one of the device interfaces.
