14523 results about "Multiplexer" patented technology

In electronics, a multiplexer (or mux), also known as a data selector, is a device that selects between several analog or digital input signals and forwards it to a single output line. A multiplexer of 2ⁿ inputs has n select lines, which are used to select which input line to send to the output. Multiplexers are mainly used to increase the amount of data that can be sent over the network within a certain amount of time and bandwidth.

Headend cherrypicker multiplexer with switched front end

A headend or central office or satellite uplink facility for receiving upstream video-on-demand requests and MPEG transport streams containing video program data and packetizing said video data into TCP / IP or UDP / IP packets and LAN packets and routing them through a switch to one or more cherrypicker multiplexers. Each cherrypicker multiplexer receives LAN packets, depacketizes the MPEG data, partially or fully decompresses the data and recompresses the data to another smaller bandwidth, and repacketizes the data into MPEG packets or TCP / IP or UDP / IP packets. The repacketized TCP / IP or UDP / IP packets are transmitted directly to the customer as TCP / IP or UDP / IP packet data. MPEG packets generated by the cherrypicker multiplexer are, optionally, encapsulated in LAN packets addressed to an IP dewrapper circuit. There, they are depacketized back to MPEG packets and transmitted to the appropriate transmitter or modem for transmitting to a customer. Internet data and data from application servers, referred to as iData, can also be transmitted to customers through the cherrypicker multiplexers or a downstream modem, and upstream iData can be received through the modem.

FPGA with register-intensive architecture

Field programmable gate arrays (FPGA's) may be structured in accordance with the disclosure to have a register-intensive architecture that provides, for each of plural function-spawning LookUp Tables (e.g. a 4-input, base LUT's) within a logic block, a plurality of in-block accessible registers. A register-feeding multiplexer means may be provided for allowing each of the plural registers to equivalently capture and store a result signal output by the corresponding, base LUT of the plural registers. Registerable, primary and secondary feedthroughs may be provided for each base LUT so that locally-acquired input signals of the LUT may be fed-through to the corresponding, in-block registers for register-recovery purposes without fully consuming (wasting) the lookup resources of the associated, base LUT. A multi-stage, input switch matrix (ISM) may be further provided for acquiring and routing input signals from adjacent, block-interconnect lines (AIL's) and/or block-intra-connect lines (e.g., FB's) to the base LUT's and/or their respective, registerable feedthroughs. Techniques are disclosed for utilizing the many in-block registers and/or the registerable feedthroughs and/or the multi-stage ISM's for efficiently implementing various circuit designs by appropriately configuring such register-intensive FPGA's.

Method and Apparatus For Multimodal Voice and Web Services

This invention is based on being able to locate a voice server, temporarily allocate it, send it the audio of you saying “When is flight 683 due to arrive?”, getting the results of what you said back in the browser, and deallocating the voice server for use by the next person talking into their browser. Voice channels and IVR ports are initially set up by a switch and the IVR using conventional audio protocols. The Voice channels are not initially connected to the client. The switch handles the allocation and deallocation of IVR voice channels without having to communication further with the IVR. A user indicates (usually by pressing a PTT button) to the client device that he wishes to initiate a voice interaction during an X+V session. This translates to a request on the CTRL channel to synchronise the XHTML and VXML forms which the embodiment uses as a trigger for the VXML browser to execute a conversational turn. The multiplexer intercepts this control command and connects the virtual voice circuit between the device and an existing open but unattached voice port. The virtual circuit is connected without having to set up an RTP channel. The CTRL signal is then forwarded to the interaction manager so that the conversation can take place. At the end of the conversation the virtual circuit is disconnected.

Apparatus and method for transmitting/receiving data in a multi-antenna communication system

An apparatus for transmitting data in a base station of a wireless communication system that transmits data depending on channel status information fed back from terminals and uses a plurality of antennas. Based on the channel status information, a scheduler determines a terminal to which the base station will transmit data, determines antennas via which the base station will transmit data among the plurality of antennas, and determines a space pre-coding method. A multiplexer multiplexes transmission data into a plurality of data streams according to the number of the determined antennas. A modulation and coding unit performs modulation and coding on each of the data streams. A pre-coding controller outputs a matrix select signal for selecting one of a plurality of space pre-coding matrixes according to the space pre-coding method. A space pre-coder spatial-codes each of the coded streams with the matrix selected based on the matrix select signal. An OFDM modulator performs OFDM modulation on each of the spatial-coded streams. An RF unit transmits each of the OFDM-modulated streams via an associated antenna.

Upstream only linecard with front end multiplexer for CMTS

An upstream line card including a digital or analog multiplexer front end circuit for a Cable Modem Termination System. Each upstream line card has only upstream receivers and allows a CMTS to share one or a handful of receiver chips to receive and recover data from a larger number of input cables coupled to the front end multiplexer. A control circuit for the multiplexer uses MAP data and burst assignment data and upstream mini-slot counts for each of the input cables to determine when a burst is about to arrive on a cable and cause appropriate switching by the multiplexer or crossbar switch. In some embodiments, there is only one RF channel circuit coupled to the output of the multiplexer, so the multiplexer is controlled to couple the input cable upon which the burst is expected to the single RF channel. In other embodiments, there are multiple RF channels coupled to the inputs of the multiplexer so the multiplexer is controlled to connect each input cable on which a burst is expected to an available RF channel. In some embodiments, the sample data generated by each RF channel is buffered and an arbiter picks one burst at a time for application to the input of a CMTS receiver or doles out bursts to different receivers. In other embodiments, no buffers or arbiter are used, and each RF channel has its own dedicated CMTS receiver.
