Publication number: 20110293025Abstract: Systems and methods which provide for reduced intra communication system information transfer by providing a compressed representation of a portion of intra communication system information are shown. An embodiment operates to provide intra communication system transfer of uncompressed received information while providing intra communication system transfer of a compressed representation of information ancillary to the received information. According to embodiments, ancillary information, such as CSI, associated with other transferred information is transferred with reduced data throughput requirements through application of compression techniques with respect to the transferred ancillary information. Embodiments additionally or alternatively reduce the intra communication system information transferred by reducing the received information transferred.Type: ApplicationFiled: May 25, 2010Publication date: December 1, 2011Applicant: Microtune (Texas), L.P.Inventors: Sriaram Mudulodu, Jordan C.

Patent number: 7430020Abstract: The present invention relates to separation of composite video signals, such as NTSC or PAL signals. In particular, it relates to accurate decoding of chrominance and luminance components, which may reduce so-called dot crawl and false color artifacts of at least some images.Type: GrantFiled: July 7, 2005Date of Patent: September 30, 2008Assignee: ESS Technology, Inc.Inventors: Jordan C. Cookman, Cai-Zhang Zhou

Patent number: 7277491Abstract: An electrical isolation barrier for use in a Data Access Arrangement uses a high frequency (HF) transformer 24 to provide isolation. An input signal, which may be analog or digital, is connected to a modulator. The analog output of the modulator is connected to the input of the HF transformer. The output of the HF transformer is connected to the input of a demodulator. Simple amplitude modulation can be used in the modulator to modulate the input signal to the frequency range of operation of the HF transformer. A simple low pass filter may be incorporated in the demodulator to remove harmonic distortion caused by the HF transformer. The output signal of the demodulator is substantially the same as input signal.Type: GrantFiled: May 14, 2002Date of Patent: October 2, 2007Assignee: ESS Technology, Inc.Inventors: Ping Dong, Jordan C.

Patent number: 7151574Abstract: A device and method are provided for implementing digital baseband separation of composite video signals with reduced memory requirements. The method and device require that only the composite signal be stored in a large delay element. Multiple quadrature demodulators are employed to generate multiple delayed complex baseband signals. Therefore, no large complex baseband delay element is required.Type: GrantFiled: December 1, 2003Date of Patent: December 19, 2006Assignee: ESS Technology, Inc.Inventors: Ping Dong, Jordan C. Cookman

Patent number: 7027399Abstract: A device for use in a modem configuration that enables the transfer of data from a host signal processor (HSP) to an A/D-D/A converter or CODEC with less data loss, with low noise and that can send data at varying carrier frequencies without changing the size of the buffers. The device further allows for data transfer that is flexible with any given modulation scheme, carrier frequency or baud frequency to conform with the V.34, V90, as well as prior and subsequent recommendations. The device further includes a counter for counting the number of data samples transferred between the CODEC and the HSP and for alerting the HSP to avoid an overflow condition. The counter is further configured to count beyond the physical size of the buffer in order to simplify operation in an overflow condition. A transmit buffer is included for transferring data from the HSP to the CODEC.Type: GrantFiled: August 9, 2001Date of Patent: April 11, 2006Assignee: Ess Technology, Inc.Inventors: Jordan C.

Patent number: 7020674Abstract: A method and device are provided that allow computation of multiple modulus conversion (MMC) outputs using little or no division operations. Instead of division operations, multiplication and logical shift operations are used to produce pseudo-quotients and pseudo-remainders, which may be corrected in a final step to produce correct MMC outputs. This allows for more efficient implementation, since division is typically less efficient than multiplication and logical shift. The method and device operate on MMC inputs that may be partitioned into sub-quotients of varying numbers of digits in any numbering system. The multiplication and logical shift operations are performed on each of the sub-quotients according to a procedure derived from long-division techniques.Type: GrantFiled: November 25, 2003Date of Patent: March 28, 2006Assignee: Ess Technology Inc.Inventors: Jordan C.
