Abstract: Pixel clock frequency and optimum sampling phase adjustment is an important requirement in Flat panel display monitors (FPDM) with an analog video interface. This invention proposes a new and more advanced method for frequency an optimum sampling phase determination. It is based on analyzing the content of the image to arrive at an optimum value of phase and frequency by directly optimizing image quality. The method differs from exsisting methods on two counts. First, no assumptions are needed about the precise value of expected frequency. Second, instead of following a two step approach of first determining frequency and then phase, this invention makes possible a single pass phase-frequency optimization.

Abstract: A network device, capable of understanding communications between an end user and the core network on a RAN network is disclosed. In some embodiments, the device is able to decode the control plane and the user plane. As such, it is able to determine when the end user has requested multimedia content. Once this is known, the device can optimize the delivery of that content in several ways. In one embodiment, the device requests the content from the content server (located in the core network) and transmits this content in a just-in-time manner to the end user. In another embodiment, the device automatically changes the encoding and resolution of the content, based on overall monitored network traffic. In another embodiment, the device automatically selects or modifies the format and resolution options based on overall bandwidth limitations, independent of the end user.

Abstract: An embodiment of a hysteretic power-supply controller includes a signal generator, frequency adjuster, and signal combiner. The signal generator is operable to generate a switching signal having a first level in response to a control signal being greater than a first reference value and having a second level in response to the control signal being less than a second reference value, the switching signal having an actual frequency and being operable to drive a switching stage that generates a regulated output signal. The frequency adjuster is operable to generate a frequency-adjust signal that is related to a difference between the actual frequency and a desired frequency. And the signal combiner is operable to generate the control signal from the frequency-adjust signal and the regulated output signal. Such a hysteretic power-supply controller may allow one to set the switching frequency to a desired value independently of the parameters of the power supply.

Abstract: Circuits, methods, and apparatus for adjusting an NCO output in order to provide a signal that is phase-locked to a reference signal. This is particularly beneficial where the frequencies of the NCO output and reference signal are unrelated. One embodiment provides a circuit that corrects the phase of the NCO output in two steps in order to reduce the chance of metastability. During the first, the output of the NCO is phase shifted to the closest correct portion of a cycle of a clock signal. A second correction is then performed by steering a number of currents under the control of at least some of a number of remainder bits from the NCO. The current steering provides a die area efficient, low-noise phase correction. The decoded remainder bits are latched using a feed forward circuit that prevents the device from entering a locked state.

Abstract: A method and system for scaling an image in accordance with the present invention is disclosed. The method utilizes a plurality of interpolators operating in parallel. Each interpolator operates with a different spatial offset with respect to the other. The final output is the average the output of each interpolator. Normally the initial value of the horizontal and vertical DDA's is zero. Offset is introduced by introducing an initial value in the DDA. Offset has the physical effect of manipulating the weights required for the averaging process in interpolation. Horizontal offset is the initial value in the Horizontal DDA while the vertical offset is the initial value in the Vertical DDA. The present invention relates to implementation in a semiconductor integrated circuit but the concepts can be used in software based image resizing (scaling) algorithms too.

Abstract: The current application is directed to characterization of e-commerce-related searches and digital encoding of the characterizations in a database or other data-storage system by an e-commerce search engine. As one example, when a user enters a query term in a search textbox, the user is provided with a choice of pressing an action button labeled “I want to buy” or an action button labeled “I want to sell,” referred to as a “buy button” and “sell button,” respectively. The search engine records the buy-button and sell-button inputs along with corresponding search queries. The search-engine implementation then collects these queries from a large number of users into a database and matches them over a period of time, thus helping buyers find sellers and vice versa.
