Abstract: An open loop envelope tracking system calibration technique and circuitry are proposed. A radio frequency power amplifier receives a modulated signal. An envelope tracker power converter generates a modulated power amplifier supply voltage for the radio frequency power amplifier based on a control signal derived from the modulated signal. A first output power and a second output power of the radio frequency power amplifier are measured when the control signal is respectively delayed by a first delay period and a second delay period. A sensitivity of the output power of the radio frequency power amplifier is near a maximum near the first delay period and the second delay period. The first delay period and/or the second delay period are adjusted until the first output power substantially equals the second output power. The first delay period and the second delay period are used to obtain a calibrated fine tuning delay offset.

Abstract: A two colour fluorescent assay and a kit are described that permit the determination of live and dead parasitic or non-parasitic worms, for example helminths. The assay permits screening for the effect of one or more agents or an event on the viability of a parasitic or non-parasitic worm. In one example, the assay comprises (a) providing a sample comprising one or more parasitic or non-parasitic worms; (b) contacting the parasitic or non-parasitic worms with a concentration of fluorescein diacetate sufficient to yield detectable green fluorescence in any live parasitic or non-parasitic worms present in the sample and a concentration of propidium iodide sufficient to yield detectable red fluorescence in any dead parasitic or non-parasitic worms present in the sample; and (c) detecting the red and green fluorescence of the parasitic or non-parasitic worms.

Abstract: A record and replay apparatus comprises a transducing unit for reproducing a digital signal from a medium. A control unit controls a reproduction mode of the apparatus. A decoding is coupled to the transducing unit for decoding the digital signal and deriving therefrom a signal indicative of a specific picture type. The reproduction mode has a first period of reproduction at a normal play speed and a second period of reproduction at a speed greater than the play speed. The first and second periods alternating with the first period initiated responsive to the signal indicative of a specific picture type. In a further arrangement a first transducing unit records an MPEG signal. A control unit generates a signal, indicating an intra coded frame occurrence in the MPEG bit stream, which is recorded by a second transducing unit together with a servo reference signal.

Abstract: Video image information is received in a signal including conditional access information. The conditional access information is associated with one of a plurality of picture resolution formats for recording, reproducing and displaying the video image information. The conditional access information in the received signal is decoded. A format for at least one of recording, reproducing and displaying the video image information is adaptively selected in response to the decoded conditional access information. The video image information is then processed using the selected format. The conditional access information may further include information indicating a predetermined time period during which reproduction of recorded video image information is permitted.

Abstract: Method and apparatus for automatically enhancing the foliage display of a color signal includes providing the color signal in multiplexed form having alternating first and second components, the first component being substantially aligned with a flesh tone color space axis, the second component being substantialy aligned with a green tone color space axis. A de-multiplexing unit separates the first and second components to provide a first de-multiplexed component substantially aligned with the flesh tone axis and a second de-multiplexed component substantially aligned with the green tone axis.

Abstract: A method for operating a video processing system by receiving initial copyright information from a first source, storing the initial copyright information, receiving updated copyright information from a second source, and updating the stored copyright information in response to the updated copyright information. For example in one embodiment of the present invention, the initial copyright information for a program is received from an electronic program guide and updated copyright information is received along with the selected program. The video processing system may be programmed to operate in a first operating mode in response to the initial copyright information and the operating mode of the video processing system may be switched to a second operating mode in response to the updated copyright information.

Abstract: A system and method for eliminating absent or poor quality video sections from a video recording, such as a second generation of video recording. Synchronizing pulses associated with a video signal to be recorded are analyzed to determine whether a video signal is present and, further, to determine whether the video signal is not distorted (i.e., non-trick play mode). A recording device is selectively paused in response to the absence of a valid video signal or the presence of a video signal that is distorted, of poor quality or otherwise not worth recording.

Abstract: A signal processing method and apparatus in which a horizontal and/or vertical synchronizing signal related to a received video signal is monitored to determine if a relatively large change has occurred in the respective vertical and/or horizontal time period such that a change in video signal source may have occurred. Upon the detection of such a change, the operation of a phase lock loop (PLL) such as horizontal phase lock loop (HPLL) and/or vertical phase lock loop (VPLL) circuit is adapted as appropriate.
