Abstract: A power converter for a load with varying power requirements dynamically adjusts its supply voltage to the load so as to track the radio frequency (RF) envelope of the signal being carried by the load. The supply voltage can be provided by a multiple-output charge pump providing multiple output voltage levels concurrently, and a switch to provide a selected one of the different output voltage levels as the supply voltage to the load. A controller controls the switch to dynamically modify the voltage level selected for output as the supply voltage such that the supply voltage tracks the RF envelope of the signal being carried by the load. As the switching losses of transistors of the power converter may exceed the power savings achieved through envelope tracking, the power converter employs a peak following frequency divider circuit that limits the switching frequency of the power converter to a threshold frequency.

Abstract translation: 用于具有不同功率要求的负载的功率转换器动态地调整其对负载的电源电压，以便跟踪由负载承载的信号的射频（RF）包络。 电源电压可以由同时提供多个输出电压电平的多输出电荷泵提供，以及提供不同输出电压电平中选择的一个作为负载的电源电压的开关。 控制器控制开关以动态地修改所选择的用于输出的电压电平作为电源电压，使得电源电压跟踪由负载承载的信号的RF包络。 由于功率转换器的晶体管的开关损耗可能超过通过包络跟踪实现的功率节省，因此功率转换器采用将功率转换器的开关频率限制到阈值频率的峰值跟随分频器电路。

Abstract: A wireless display system and method decompresses a compressed video stream, such as obtained from suitable video sources such as a cable modem, DVD player or other suitable source, to produce a decompressed video stream locally. The decompressed video stream, such as frames, is stored in a local frame buffer, such as an on-chip frame buffer, system memory, or any other suitable memory. The system and method then recompresses the stored frames and wirelessly transmits the recompressed frames using a short range wireless transmitter, such as a radio frequency-based short range transmitter, an infrared short range wireless transmitter, or any other suitable short range transmitter that may provide, for example, local area networking. Accordingly, full image frames are decompressed and then recompressed, such as via a software data encoder as executed by a central processing unit, or via a hardware data encoder, such as an MPEGII or MPEG4 encoder, or any other suitable encoder, and then modulated by a short range wireless transceiver and sent to a short range wireless unit having a local display.

Abstract: To apportion desired video processing between a video source device and a video sink device, at one of the devices, and based upon an indication of video processing algorithms of which the other device is capable and an indication of video processing algorithms of which the one device is capable, a set of video processing algorithms for achieving desired video processing is identified. The identified set of video processing algorithms is classified into a first subset of algorithms for performance by the other device and a second subset of algorithms for performance by the one device. At least one command for causing the other device to effect the first subset of video processing algorithms is sent. The one device may be configured to effect the second subset of algorithms.

Abstract: A texture compression method is described. The method comprises splitting an original texture having a plurality of pixels into original blocks of pixels. Then, for each of the original blocks of pixels, a partition is identified that has one or more disjoint subsets of pixels whose union is the original block of pixels. The original block of pixels is further subdivided into one or more subsets according to the identified partition. Finally, each subset is independently compressed to form a compressed texture block.

Abstract: Briefly, methods and apparatus to provide image content to, and display image content on, variable refresh rate displays with reduced input lag. The methods and apparatus allow for image tearing, or the displaying of image content from more than one video frame, when the render rate of a provided video frame falls outside the display refresh rate range of a variable refresh rate display when the display is refreshing with a previous frame (e.g. the display is in active refresh), thus reducing the input lag of the content of the provided video frame. The methods and apparatus may also prevent image tearing when the render rate of provided video frames is within the display refresh rate range of a display.

Abstract: A method for determining a macroblock (MB) coding mode for a current MB in a dependent view. A window around a co-located MB in a base view is determined, wherein the co-located MB is a MB in the base view having a same location as the current MB in the dependent view. A coding mode complexity value (CMCV) is determined for each MB in the window, wherein the CMCV is based on a coding mode used to encode the MB. Rate distortion optimization (RDO) is performed for the current MB using a reduced number of coding modes if a total CMCV for all MBs in the window is less than a threshold, or using all supported coding modes if the total CMCV for all MBs in the window is greater than the threshold. A coding mode for the current MB is determined based on the RDO results.

Abstract: A method and apparatus provide for improving signal quality. The method includes receiving a first media signal, such as a video signal, in a first format, such as 1080p. The provided video signal is one that is created by upsampling a video signal recorded in a format having a lower sampling rate. The method also includes obtaining a second signal indicative of error within the first media signal. The second signal is in a second format, such as the format having a lower sampling rage in which the video signal was recorded. The signal is processed to place the second signal in the format of the first signal. Then, the estimated error signal is combined with the original signal to arrive at an error corrected output.
