Abstract: A system and method for high-quality variable speed playback of audio-visual (A/V) media is provided. The system receives an encoded visual signal and an encoded audio signal. The encoded visual signal is decoded to generate a decoded visual signal and the encoded audio signal is decoded to generate a decoded audio signal. The decoded audio signal is time scale modified to generate a time scale modified audio signal. The decoded visual signal and the time scale modified audio signal are then synchronized for playback at a predefined playback speed. Only partial decoding of the encoded audio signal may be performed to conserve processing power.

Abstract: A method for operating a Radio Frequency (RF) receiver of a wireless terminal. During a first time interval, an RF front end is enabled and the RF receiver receives and processes an RF signal, e.g., a Wideband Code Division Multiple Access (WCDMA) signal, to produce a baseband signal and to store samples of the baseband signal. During a second time interval that differs from the first time interval, the RF front end is disabled and the RF receiver processes the plurality of samples of the baseband signal of the first time interval to measure signal strengths of a plurality of pilot signals present in the baseband signal of the first time interval. Finally, during a third time interval that differs from the first time interval and the second time interval, the RF front end is enabled and the RF receiver receives and processes an RF signal of the third time interval to extract data there from. Memory is shared between the first, second, and third time intervals for different uses.

Abstract: Methods and apparatus for generating and performing digital communications using a randomized generatable interleaver. In accordance with one exemplary embodiment of the invention, a pseudo random interleaver of size n*m with excellent randomness and spread properties may be generated from a set of seed values. The interleaver of size N=n*m is defined by dividing the N possible address in the interleaver (0?N?1) into n subsets. The subsets are preferably generatable from a single value within the subset either using an algorithm or a memory based lookup table. The set of n seeds comprises one value selected from each subset. An improved communication system incorporating the aforementioned interleaver and using turbo codes or other concatenated coding systems is also disclosed.

Abstract: The invention allows data originating according to a first communications standard to be transmitted over a physical layer using a second communications standard. According to an embodiment of the invention, a data stream is received from a physical transmission medium that uses particular first communications standard. Next, a data type identification (DTID) is appended to each byte in the data stream, thereby creating a technology independent data stream having a particular bit rate. This bit rate is then matched to a different bit rate that corresponds to a second communications standard. The technology independent data stream is then transmitted over a physical transmission medium that uses the second communications standard.

Abstract: Various systems and methods providing high speed decoding, enhanced power reduction and clock domain partitioning for a multi-pair gigabit Ethernet transceiver are disclosed. ISI compensation is partitioned into two stages; a first stage compensates ISI components induced by characteristics of a transmitters partial response pulse shaping filter in a demodulator, a second stage compensates ISI components induced by characteristics of a multi-pair transmission channel in a Viterbi decoder. High speed decoding is accomplished by reducing the DFE depth by providing an input signal from a multiple decision feedback equalizer to the Viterbi based on a tail value and a subset of coefficient values received from a unit depth decision-feedback equalizer. Power reduction is accomplished by adaptively truncating active taps in the NEXT, FEXT and echo cancellation filters, or by disabling decoder circuitry portions, as channel response characteristics allow.

Abstract: A method and apparatus for determining long term orbit (LTO) models using variable time-horizons to improve the orbit and clock model accuracy. The method and apparatus use either historic ephemeris or historic measurements for at least one satellite to produce an orbit parameter prediction model (an LTO model). The parameter predicted by the model is compared to an orbit parameter of a current broadcast ephemeris. The result of the comparison (an indicia of accuracy for the model) is used to establish a time-horizon for the orbit parameter prediction model for that particular satellite. Such a time-horizon may be established in this manner for each satellite within a satellite constellation.

Abstract: An equalizer that compensates for non-linear effects resulting from a transmitter, a receiver, and/or a communication channel in a communication system. A non-linear decision feedback equalizer compensates for the non-linear effects impressed onto a received symbol by selecting between equalization coefficients based upon a previous received symbol. The received symbol may be represented in form of logic signals based on the binary number system. When the previous received symbol is a binary zero, the non-linear decision feedback equalizer selects an equalization coefficient corresponding to binary zero to compensate for the non-linear effects impressed onto the received symbol. When the previous received symbol is a binary one, the non-linear decision feedback equalizer selects an equalization coefficient corresponding to binary one to compensate for the non-linear effects impressed onto the received symbol.

Abstract: An audio processing system which allows a surround sound system to utilize the transmission bandwidth efficiently by adaptively transmitting a supplementary data from a secondary source in addition to the audio signals of a primary source. The system consists of a transmitter component, capable of transmitting audio signals from a primary source and adaptively inserts supplementary data of the secondary source in the reserved communication bandwidth. The transmitter inserts headers in the channels used by the supplementary data to allow the receivers to identify the channel allocation between the primary source and the secondary source. Another part of the audio processing system is that of a receiver component which is capable of discriminating between data from the primary source and data from the secondary source.

Abstract: A DSP based SERDES performs compensation operations to support high speed de-serialization. A receiver section of the DSP based SERDES includes one or more ADCs and DSPs. The ADC operates to sample (modulated) analog serial data and to produce digitized serial data (digital representation of the modulated analog serial data). The DSP communicatively couples to the ADC and receives the digitized serial data. Based upon the known characteristics of the digitized serial data and the digitized serial data itself, the DSP determines compensation operations to be performed upon the serial data to compensate for inadequacies of the receiver and/or channel response. These compensation operations may be (1) performed on the analog serial data before digitization by the ADC; (2) applied to the ADC to modify the operation of the ADC; and/or (3) performed on the digitized serial data by the DSP or another device.

Abstract: A system and method for improving decisions for 2D combing of a video. A 2D-comb is applied to a baseband video signal, thus producing a chroma component of the signal, and an associated combing error. A narrowband filter is applied to the chroma component to produce a filtered chroma component. The chroma component and the filtered chroma component are blended in proportions based on the amount of combing error to produce a new chroma component. A larger combing error induces selection or blending a larger portion of the filtered chroma component, which as a result of narrowband filtering contains less cross-chroma error. Subtracting the new chroma component from the baseband video signal produces a new luma component. The chroma component can also be filtered using a wider band filter to produce a non-complementary chroma component to be subtracted from the baseband video signal to produce the new luma component.
