A gateway application in a content engine multiplexes requests for real-time content to servers that, in turn, service the requests by streaming appropriate real-time content to requesting users. A software communication port of the content engine may be reserved to receive request messages from multiple client computers, at least two of which request streaming of real-time content according to different selected formats. After identifying client properties (e.g., a format for which to receive streaming real-time content) associated with the requests for real-time content, the gateway application identifies corresponding servers of the content engine to serve the real-time content according to the different selected formats. The gateway application forwards the requests for streaming of real-time content associated with the request messages to the corresponding servers which, in turn, satisfy the requests by streaming the requested real-time content to the client computers.

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.

The invention relates to a new structure of a control channel region within a sub-frame of a 3GPP-based based communication system using OFDM in the downlink. This new structure of a control channel region is inter alia particularly suitable for conveying physical downlink control channel information from a donor eNodeB to a relay node. The control channel region is divided in CCEs that have equal size irrespective of the presence of further cell-specific and/or UE-specific reference signals within the control channel region. This is achieved by dividing the control channel region in plural sub-CCEs that are combined to CCEs all having equal size (in terms of resource elements that can be used for the signaling of control information). The control channel region is divided in the frequency domain and/or time domain in a FDM respectively TDM fashion in order to obtain the sub-CCEs

Lastly, the network parameters that most affect the QoE as a function of the relevance thereof for predictions of quality are automatically identified in order to provide the values needed to attain a certain quality of experience as defined by the user.

An approach is provided for generating Low Density Parity Check (LDPC) codes. An LDPC encoder generates a LDPC code with an outer Bose Chaudhuri Hocquenghem (BCH) code. For a rate 3/5 code, the approach provides a degree profile that yields reduced memory requirements for storage of the edge values without significantly affecting the performance with respect to an “unmodified” rate 3/5 code. The relevant parameters for the reduced memory LDPC codes are as follows: q=72, n_ldpc=64800, k_ldpc=n_BCH=38880, k_BCH=38688. The above approach has particular application in digital video broadcast services over satellite.

A HTTP request is sent to a web server. A HTTP request including HTTP request data is received. A connection identifier is associated with the HTTP request. The receiving and associating steps are repeated for one or more HTTP requests. The connection identifier and the associated HTTP request data for the one or more HTTP requests are then sent in a single stream to the web server (e.g., HTTP process). When a HTTP request including HTTP request data are processed by a web server, the HTTP request data and an associated connection identifier are received. HTTP response data associated with the HTTP request data is obtained. The HTTP response data and the connection identifier are then sent.

Disclosed is a method for allocating and accessing downlink resources in the OFDMA communication system. In the resource allocation method, bursts having the same modulation and channel encoding level are arranged in a predetermined temporal order on a physical layer. Information on the allocated unit resources is included in a common control block and is transmitted to a subscriber station, and the subscriber station then detects a number of the allocated unit resources to thus check the range of bursts to be received by the subscriber station. Therefore, power consumption by the subscriber station is reduced and signaling overheads of the common control information and unneeded residual resources are decreased.

An approach is provided for generating Low Density Parity Check (LDPC) codes. An LDPC encoder generates a short LDPC code by shortening longer mother codes. The short LDPC code has an outer Bose Chaudhuri Hocquenghem (BCH) code. According to another aspect, for an LDPC code with code rate of 3/5 utilizing 8-PSK (Phase Shift Keying) modulation, an interleaver provides for interleaving bits of the output LDPC code by serially writing data associated with the LDPC code column-wise into a table and reading the data row-wise from right to left. The above approach has particular application in digital video broadcast services over satellite.

An approach is provided for encoding short frame length Low Density Parity Check (LDPC) codes. An encoder generates a LDPC code having an outer Bose Chaudhuri Hocquenghem (BCH) code. Structure is imposed on the LDPC codes by restricting portion part of the parity check matrix to be lower triangular and/or satisfying other requirements such that the communication between bit nodes and check nodes of the decoder is simplified. Further, a cyclic redundancy check (CRC) encoder is supplied to encode the input signal according to a CRC code. This approach has particular application in digital video broadcast services over satellite.

The interception control means and the interception gateway element may both be integrated in the second network element. The interception system has a clear advantage in scalability, no single point of failure, and an adaptation to different authority interfaces can be implemented only in the interception gateway. The network elements can be similar to a high extent for all different authority requirements.

The process of obtaining an insurance quote is currently based on information provided by filing online forms. Insurance companies use the consumer input data from online the forms to provide a quote for property insurance and for insurance underwriting. To complete the underwriting, the insurance companies have to make assumptions on various factors; for example, the structure and layout of a consumer's home, what type of content the consumer owns, its value, and its condition, among several others. It is desirable to get more accurate data on the consumer content, the structure and layout of the home, as well as other factors (e.g., hazards such as whether a house is on a canyon) in an automated fashion which would let insurance companies underwrite policies with a more accurate risk profile as well as save costs by not having to send an onsite inspector.
