Patent number: 10467983Abstract: A later generation display device may be connected to the video output port of an older electronic device which utilized an earlier generation display such as a dot matrix display. The early generation display is replaced with the later generation display. The display device includes software which receives graphic data through the video output port and identifies which frame is currently being streamed. The display device matches the frame being streamed to a stored graphic frame having a higher resolution and/or color. The matched frame is delivered to the later generation device so that the user can experience a higher quality visual effect by retrofitting the older electronic device with the later generation display.Type: GrantFiled: March 29, 2018Date of Patent: November 5, 2019Inventor: Randall Bret Perlow

Patent number: 6810090Abstract: A method and apparatus for providing direct conversion of baseband digital symbols to a desired frequency (e.g., IF or RF) without the need for analog up conversion. The apparatus of the present invention is a VSB modulator comprising a complex frequency shifter, an interpolation filter, an optional pilot inserter, a DDS quadrature modulator and an optional image rejector and DAC compensator. The architecture of the present VSB modulator can be implemented using digital integrated circuit technologies, thereby significantly reducing the cost of devices that require a VSB modulator.Type: GrantFiled: February 15, 2000Date of Patent: October 26, 2004Assignee: Sarnoff CorporationInventor: Randall Bret Perlow

Patent number: 6680971Abstract: A passband equalizer that performs blind equalization upon a complex signal, e.g., a vestigial sideband (VSB) signal, without using a training sequence. The passband equalizer contains a decision directed equalizer (DFE) that operates upon separate in phase (I) and quadrature phase (Q) signals using a filter for the I signal and a filter for the Q signal without using filters for cross components of the I and Q signals. As such, the DFE contains approximately half of the multipliers and adders that are used in prior art DFEs.Type: GrantFiled: December 7, 1998Date of Patent: January 20, 2004Assignees: Sarnoff Corporation, Motorola Inc.Inventors: Mehmet Vakif Tazebay, Randall Bret Perlow

Patent number: 6516036Abstract: Method and apparatus for determining the correct set of samples to retain in applying a decimation process. The present method provides an automatic approach to determine the timing phase of the desired samples to decimate the oversampled input signal (data sequence), thereby producing the underlying data signal.Type: GrantFiled: December 15, 1999Date of Patent: February 4, 2003Assignees: Sarnoff Corporation, Motorola, Inc.Inventors: Cheng-Youn Lu, Randall Bret Perlow, Charles Reed, Jr.

Patent number: 6430234Abstract: A method and apparatus for performing phase detection and timing recovery for a vestigial sideband (VSB) signal by processing a complex valued passband VSB signal using a high order non-linearity to detect the phase of the VSB signal. As such, an all digital solution to timing recovery for a high definition television is provided.Type: GrantFiled: July 30, 1998Date of Patent: August 6, 2002Assignees: Sarnoff Corporation, Motorola Inc.Inventor: Randall Bret Perlow

Patent number: 6351293Abstract: A decision directed phase detector that uses the quantized data output from a slicer to aid the phase error detection process to determine a phase error of a complex signal such as a vestigial sideband (VSB) signal containing in phase (I) and quadrature phase (Q) components (I and Q signals). The phase detector comprises subtractor having one input coupled to the I signal and a second input coupled to the data output of the slicer representing the magnitude of a sample point within a symbol. The quantized signal is subtracted from the I signal to produce &Dgr;I signal. The Q signal is processed to determine its sign and magnitude. The sign and magnitude values are multiplied together and the result is multiplied with the &Dgr;I signal to produce the phase error between the I and Q signals. This phase error signal is used in a digital television receiver to extract a data signal from a VSB signal for demodulation.Type: GrantFiled: July 13, 1998Date of Patent: February 26, 2002Assignees: Sarnoff Corporation, Motorola Inc.Inventor: Randall Bret Perlow
