摘要： A method and system that improves voice recognition by improving storage of voice recognition (VR) templates. The improved storage means that more VR models can be stored in memory. The more VR models that are stored in memory, the more robust the VR system and therefore the more accurate the VR system. Lossy compression techniques are used to compress VR models. In one embodiment, A-law compression and A-law expansion are used to compress and expand VR models. In another embodiment, Mu-law compression and Mu-law expansion are used to compress and expand VR models. VR models are compressed during a training process and they are expanded during voice recognition.

摘要： A broadband communication system (60), such as a cable television system, includes a forward path for transmitting information from headend equipment to subscribers and a reverse path for transmitting information from the subscribers to the headend equipment. The reverse path includes a transmitting station (65) that receives a first analog signal, converts the first analog signal to a first digital signal having a first number of bits, encodes the first digital signal to generate a second digital signal having a second number of bits less than the first number of bits, then optically transmits the second digital signal. A receiving station (70), also located in the reverse path, receives the second digital signal, decodes the second digital signal to generate a third digital signal having a third number of bits greater than the second number of bits, then converts the third digital signal to a second analog signal that approximates the first analog signal.

摘要： A precoding and decoding system to achieve rates higher than 33.6 kbps in the analog modem to digital modem direction. The system modifies the standard Tomlinson Harashima Precoding algorithm to adapt it for use in PCM modems. Instead of an arithmetic modulo operation that is implemented in the transmitter, the invention defines a Discrete Modulo Operation that performs the function of limiting the amplitude of the transmitted signal.

摘要： A method and apparatus for preserving the dynamic range of a relatively high dynamic range information stream, illustratively a high resolution video signal (51), subjected to a relatively low dynamic range encoding and/or transport process(es). The invention subjects the relatively high dynamic range information stream to a segmentation and remapping process (10) whereby each segment is remapped to the relatively low dynamic range appropriate to the encoding and/or transport process(es) utilized. An auxiliary information stream (54) includes segment and associated remapping information such that the initial, relatively high dynamic range information stream may be recovered in a post-encoding (i.e. decoding) or post-transport (i.e. receiving) process.

摘要： Audio content in a single-bit audio stream can be reproduced at a transducer by mapping the single-bit audio stream to symbols in a multi-bit audio stream. Volume control may be implemented, in part, in the digital domain and, in part, in the analog domain. In the digital domain, when converting the single-bit audio stream to a plurality of symbols, the plurality of symbols is selected based, at least in part, on audio content of the single-bit audio stream and a desired volume level. In the analog domain, when converting an analog current signal output from a current- steering DAC processing the plurality of symbols to an analog voltage signal, an analog gain value may be selected based, at least in part, on the desired volume level.

摘要： A single-bit audio stream can be converted to a modified single-bit audio stream with a constant edge rate while maintaining a modulation index of the original audio stream using direct mapping. With direct mapping, a pre-filter bank may be combined with a multi-bit symbol mapper to select symbols for the modified audio stream with a constant edge rate per symbol and the same modulation index as the original audio stream. The output of the pre-filter bank may be an audio stream with no consecutive full-scale symbols. Using the output of the pre-filter bank, a multi-bit symbol mapper may use the symbol selector to output a symbol with a constant edge rate per symbol and the same modulation index as the original signal. The symbols may be converted to an analog signal for reproduction of audio content using a transducer.

摘要： A digital log gain to digital linear gain multiplier is disclosed. The digital log gain to digital linear gain multiplier includes a log gain splitter adapted to split a log gain input into an integer log part and a remainder log part. A log scale-to-linear scale converter is adapted to output a linear gain value in response to the integer log part and the remainder log part. A gain multiply circuit is adapted to multiply a digital signal by the linear gain value to output a gain-enhanced digital signal.

摘要： A method in a modem having a frame having a plurality of slots, for determining whether incoming DIL sequence information contains A-law or mu-law is provided. From the DIL sequence information, an ordered table of levels for each slot is generated. The levels of all non-robbed-bit slots are averaged, and average levels are subjected to an A-law/mu-law separation function. The separation function F1(n1,n2)=sum from i=n1 to i=n2 {L(i) - 2* [L(i-16]} effectively compares values of a first plurality of levels L(i) to twice the values of a second plurality of levels sixteen levels removed from the first plurality of levels (420). The sum is compared to a threshold (430), as the sum will be small for A-law values and large for mu-law values.

摘要： A data translation system (100) for performing a non-linear data translation on a digitized AC signal is provided. The non-linear data translation system (100) includes an input for receiving the digitized AC signal, an output for outputting a non-linearly translated signal, and a processing system (104) coupled to the input and to the output. The processing system (104) is configured to receive the digitized AC signal, non-linearly translate the digitized AC signal using a predetermined transfer function to create the non-linearly translated signal, and transfer the non-linearly translated signal to the output.
