摘要： A wireless transmission system having a transmitter and receiver is described. In one embodiment, the transmitter includes an electronically-controlled switch controlled by a first pulse width modulation control circuit, the switch configured to pull current through a first inductor when the switch is closed, the first pulse width modulation control circuit outputting a PWM output signal to control the switch. A first feedback signal obtained from a control input of the switch. A second feedback signal obtained from a terminal of the inductor, wherein a control feedback signal is computed, at least in part, as a difference between the first feedback signal and the second feedback signal is provided to the first pulse width modulation control circuit. In one embodiment, the receiver includes a second pulse with modulation controller, the second pulse width modulation controller controlling the receiver switch to deliver a desired power from the receiving coil to a load.

摘要： The disclosure relates to techniques for switching between channels of digital multimedia content. In particular, a decoding device decodes and renders to a display at least one frame of a segment of data prior to receiving the entire segment. In certain aspects, the decoding device may render one of the frames of the segment and freeze the rendered frame until the decoding device receives all of the frames of the segment. In other aspects, the decoding device may render frames of one or more segments at a reduced rendering rate until the receiving and rendering operations of decoding device are synchronized such that the rendering of the current segment occurs at substantially the same time as the receiving of the next segment. By rendering at least frame prior to receiving the entire segment the decoding device more quickly displays content to a user during a channel switching event.

摘要： Methods and systems for encoding data in a communication network are presented. In an aspect, a method is provided for processing multimedia data. The method includes detecting a smoothness factor associated with one or more portions of the multimedia data, and determining that smoothing is required based on the smoothness factor. The method also includes moving selected multimedia data from a first selected portion of the multimedia data to a second selected portion of the multimedia data, wherein the smoothness factor is adjusted. In an aspect, an apparatus is provided that includes a detector configured to detect a smoothness factor associated with one or more portions of the multimedia data, and to determine that smoothing is required based on the smoothness factor. The apparatus also includes an encoder configured to move selected multimedia data from a first selected portion of the multimedia data to a second selected portion of the multimedia data.
