Abstract: A method and apparatus for secure distribution of digital content is provided. In accordance with at least one embodiment, an intermediate device maintains an authorized content sink list which it uses to allow reauthorization of a first content sink for access to first content from a first content source when the first content sink has a first content sink entry on the authorized content sink list. In accordance with at least one embodiment, reauthorization is conditioned upon a first content sink entry currency status having not yet expired. In accordance with at least one embodiment, the intermediate device allows authentication of the first content sink by the first content source when no first content sink entry exists on the authorized content sink list or when the first content sink entry currency status has expired.

Abstract: Un método y aparato para compensación automática de pérdida de inserción en señales de video transmitidas sobre conductores es presentada. La presente invención es particularmente aplicable a la transmisión de video sobre longitudes largas de cable CAT-5 o cables dobles torcidos similares. Una señal de referencia teniendo una resistencia y forma conocida (e.g. una señal de impulso) es proporcionada para cada par de conductores transportando un componente de señal de video desde un transmisor a un receptor. El receptor incluye amplificadores de ganancia ajustables para cada par conductor sobre el cual un componente de la señal de video es transmitido. La ganancia de los amplificadores es fijada inicialmente a un nivel inicial (e.g., su ganancia máxima) para permitir la detección de una señal de referencia. Una vez que la señal de referencia es detectada en un par conductor las ganancias del amplificador son ajustadas de manera que el nivel de la señal de referencia es restaurada aproximadamente a su resistencia y forma original.

Abstract: Las perdidas de conmutacion de amplificadores de clase D se reducen al evaluar el inductor de salida para proporcionar una amplitud de ondulacion mayor que la magnitud de la corriente de carga. La amplitud de ondulacion mayor resulta en este caso en corriente de inductor negativa en carga. La conmutacion en este caso de corriente de inductor negativa reduce al minimo la energia disipada. Un circuito de inductor acoplado se adiciona para conducir la ondulacion lejos del condensador de salida.

Abstract: A simplified VCA circuit is presented. The VCA of the present invention uses fewer components and is less complex than prior art OTA-based VCAs. Further, the VCA of the present invention has improved total harmonic distortion (THD) and DC offset characteristics as compared to prior art VCAs. The VCA may be used to prevent clipping with the addition of clipping detection circuitry.

Abstract: The present invention comprises a loudspeaker system that includes a loudspeaker and a detachable mount. In one or more embodiments, the loudspeaker and mount include electrical connectors that are engaged when the loudspeaker is attached to the mount. In one or more embodiments, the loudspeaker and mount comprise mating mounting structures that support the loudspeaker on the mount when the mounting structure of the loudspeaker is engaged with the mounting structure of the mount. In one or more embodiments, mating electrical connectors are incorporated in the mounting structures such that engaging the mounting structures simultaneously engages the electrical connectors. In one or more embodiments, the loudspeaker comprises a locking mechanism that positively retains the loudspeaker on the mount. In one or more embodiments, the locking mechanism is hidden behind a flexible grill of the loudspeaker such that pressing on a corresponding location on the grill releases the locking mechanism allowing the loudspeaker to be detached from the mount. In one or more embodiments, the mount is configured to be mountable to a standard US or European electrical wiring box. In one or more embodiments, the mating mounting structures are configured to be engageable with a reduced amount of travel. In one or more embodiments, multiple configurations of the mount are provided that allow the loudspeaker to be mounted with a variety of orientations with respect to the mounting surface.

Abstract: A method and apparatus for detecting and correcting motion artifacts in interlaced video signal converted for progressive video display. A correction is applied where interlaced video material is determined to originate from film source, thereby having been converted to video using a process known as 3-2 pulldown. Where the video material is not a result of the 3-2 pulldown process, a check is made for the presence of “pixel motion” so that corrections may be applied to smooth out the pixel motion. To determine 3-2 pulldown or field motion, a video field is compared to the field prior to the previous field to generate field error. Field errors are generated for five consecutive fields and a local minimum error repeated every five fields indicate the origination of the video material from film source using the 3-2 pulldown process. Upon confirmation of 3-2 pulldown, the video material is modified to correct for the mixing of two film frames into one interlaced video frame by assuring that the two fields of the de-interlaced video frame contain data from the same film frame. Where the video material did not originate from a film source, but pixel motion is detected, the pixel motion is smoothed out by an averaging method. The odd and even fields of the resulting video data are subsequently combined to form a progressive video material.
