20100266007DUAL PDFE SYSTEM WITH FORWARD-BACKWARD VITERBI - The present invention provides a novel technique for improving the performance of equalizers by reducing the effects of error propagation in equalizers that use a Viterbi Decoder. Methods and systems are described that can improve the performance of equalizers by reducing the effects of error propagation in equalizers that use a Viterbi Decoder. Systems and methods of symbol correction in prediction decision feedback equalization (“pDFE”) architectures are described. Systems are described that include one or more enhanced Viterbi decoders together with novel methods of symbol correction to obtain better system performance. Systems and methods are described that utilize dual pDFEs and can use a blending algorithm to reduce errors in symbol decoding. Dual pDFEs are described that include forward and backward Viterbi decoders wherein the backward Viterbi decoded may operate on time reversed data blocks and with some degree of latency. Forward and backward Viterbi decoders can generate different decoded symbols from the same equalized data. A blending algorithm is described for weighting results based on reliability of the respective decoded symbols. A forward-backward blender can additionally increase performance of the second pDFE by blending long delayed trellis symbols from the first Viterbi decoder with symbols output by the second Viterbi decoder.10-21-2010

20090203365METHOD FOR PROVIDING A RECEIVER'S TERMINAL WITH MULTIMEDIA CONTENTS BEFORE A CALL IS CONNECTED - Disclosed is a method for providing a target mobile station with a multimedia content such as audio or video content before a call an originating mobile station attempted to connect is answered by the target mobile station. A mobile communication network protocol for multimedia transmission between a target mobile station and a network is established before a called party receives a call, so that multimedia such as images or moving pictures may be sent to the target mobile station before the called party answers the call. In this way, the called party is able to enjoy a multimedia service before the phone call is connected. Moreover, if the multimedia is an audio or moving picture about a calling party, the called party can identify the calling party based on the multimedia.08-13-2009
20090264138METHOD AND SYSTEM FOR TRANSMITTING MULTIMEDIA CONTENTS IN COMMUNICATION NETWORK - Disclosed is a method and system for transmitting multimedia contents in a communication network, wherein multimedia data stored in a subscriber's terminal can be automatically uploaded. The method comprises the steps of (a) transmitting a multimedia data transmission command from a terminal multimedia storage server to a terminal through a communication network; and (b) when the terminal receives the multimedia data transmission command, uploading the multimedia data stored in the terminal to the terminal multimedia storage server in response to the multimedia data transmission command.10-22-2009
20100215891RECORDING MEDIUM AND MANUFACTURING METHOD OF RECORDING MEDIUM - A recording medium and a method for manufacturing the same are disclosed. More particularly, a recording medium having a high density and high energy transfer efficiency and a method for manufacturing the same are disclosed. The recording medium includes a substrate, a recording layer formed on the substrate, a first cover layer having a first hardness formed on the recording layer, and a second cover layer having a second hardness arranged on the first cover layer.08-26-2010

20100100307Universal GPS Traffic Monitoring System - A traffic data collection process and monitoring system that uses a plurality of GPS enabled mobile devices to transmit near at real-time traffic direction and speed information to a server and or/at real-time (sub 10 second latency). The sever processes the information thereby reducing the computational load and power consumption of the mobile devices. The system uses a Traffic Pattern Recognition software program that accurately recognizes only valid traffic data while filtering out unwanted traffic data. The system creates a Distributed Traffic Data Store database containing the average speeds for designated traffic monitoring points created for the region. During use, a request for traffic data containing the boundary data and the zoom level is sent from the mobile device to the server. The server then reviews the requests and determines with specific Distributed Traffic Data Store database contains the information. The server then creates a compressed file containing the traffic information relevant to the TMPs in the request and sends it to the mobile device.04-22-2010
