摘要： A method for recovering from an excessive power cutback in a splitterless asymmetric digital subscriber line modem. The modem may apply a power cutback to enable simultaneous use of the modem and a telephone. The modem determines if the modem's power after the cutback is sufficient to support data communication with the central office. If the power is insufficient, the modem gradually reduces the power cutback, checks the sufficiency of the power again, and repeats this cycle. The modem repeats the cycle until the modem attains an acceptable transmit power where the power requirements for data transfer and noise reduction are balanced.

摘要： A method for rapid noise reduction from a splitterless ADSL modem. The modem stores a value for the power level of its transmitter in a table along with transmission characteristics of the telephone loop. The stored value for its power level is the power level that was previously successful with the transmission characteristics in achieving the Showtime data transfer mode. When the modem measures similar transmission characteristics of the telephone loop, such as a slope of the frequency response of the loop, a power level that would suppress downstream noise, or the dc voltage of the loop, the modem searches the table for matching transmission characteristics. If the table contains a table entry that matches these measured transmission to characteristics, the modem restores the stored transmitter power of the modem. In this manner, the modem may rapidly achieve Showtime because it is restoring a transmitter power level that was previously successful under the same condition of the telephone loop.

摘要： A method for reducing audible noise in a telephone from a splitterless asymmetric digital subscriber line modem. The modem examines the shape of the power spectrum of fast retrain signals both when the telephone is on-hook and off-hook. By comparing the spectra, in particular the slopes of the spectra, the modem may determine the quality of the telephone that shares the telephone loop with the modem. The modem cuts back its transmitted power depending on the quality of the telephone by an amount that suppresses the audible noise in the telephone. In this manner, a customer may simultaneously use the telephone and the modem on the same telephone loop.

摘要： A method for reducing noise from a non-linear device, such as a telephone, that shares a customer loop with a splitterless Asymmetric Digital Subscriber Line modem. The non-linearity of the device can cause some of the upstream signal to bleed into the downstream signal band. The modem examines the downstream band when it is transmitting fast retrain signals. By comparing the power in the band to a previous value when the modem transmitted upstream at a higher power level, the modem may determine whether to cut back its transmitted power to lessen the noise in the downstream band. In this manner, the method may allow optimal downstream data transfer regardless of what non-linear device shares the customer loop with the ADSL modem.

摘要： A digital subscriber line network allows a plurality of remote modems to communicate without interfering with the communication to the central office. Each symbol of a superframe is converted to a tone vector, and the tone vectors are integrated over a plurality of superframes. The tone vectors of the data symbols are random, and tend to cancel each other out. The tone vector of the synchronization symbol remains constant among the plurality of superframes, and the sum of these tone vectors over a plurality of superframes becomes large. By identifying the largest integrated tone vectors, the network may identify the position of the synchronization symbol. The modems may then align using the position of the synchronization symbol.

摘要： A chip and a chip package can transmit information to each other by using a set of converters capable of communicating with each other through the emission and reception of electromagnetic signals. Both the chip and the chip package have at least one such converter physically disposed on them. Each converter is able to (1) convert received electromagnetic signals into electronic signals, which it then may relay to leads on the device on which it is disposed; and (2) receive electronic signals from leads on the device on which it is disposed and convert them into corresponding electromagnetic signals, which it may transmit to a corresponding converter on the other device. Not having a direct physical connection between the chip and the chip package decreases the inductive and capacitive effects commonly experienced with physical bonds.

摘要： A method of compressing video data having at least one frame having at least one block and each block having an array of pixels is provided. The method transforms the pixels of each block into coefficients and creates an optimal transmission order of the coefficients. The method also optimizes the speed of processing compressed video data by partitioning the data bitstream and coding each partition independently. The method also predicts fractional pixel motion by selecting an interpolation method for each given plurality or block of pixels depending upon at least one metric related to each given block and varies the method from block to block. The method also enhances error recovery for a current frame using a frame prior to the frame immediately before the current frame as the only reference frame for lessening quality loss during data transmission. Enhanced motion vector coding is also provided.
