    • A rewind or fast forward operation may be performed in which a series of reduced-in-size images from previous frames in a video program may be presented to the viewer. In one implementation, a device may obtain sampled images corresponding to select frames of the video program and output a series of the sampled images in an order in which a sampling time corresponding to each of the sampled images in the video program monotonically increases or decreases in the output series. Differences in the sample times between successive images in the series of sampled images may not be uniform. The device may receive a selection of one of the images in the output series of sampled images and change a current output location of the video program to a location corresponding to the sampling time of the selected image.
    • 可以执行倒带或快进操作,其中可以向观看者呈现来自视频节目中先前帧的一系列缩小尺寸图像。 在一个实现中,设备可以获得与视频节目的选择帧相对应的采样图像,并且以与视频节目中的每个采样图像相对应的采样时间单调增加或减少的顺序输出一系列采样图像 输出系列。 一系列采样图像中连续图像之间的采样时间差异可能不一致。 该装置可以接收所选择的图像的输出序列中的一个图像的选择,并且将视频节目的当前输出位置改变到与所选图像的采样时间相对应的位置。

    • An exemplary method includes an adjunct content presentation system including adjunct content within a first image of a media content instance and a second image of the media content instance by setting a pixel value of a first group of pixels included in the first image and a pixel value of a second group of pixels included in the second image and corresponding to the first group of pixels to each be greater than a predetermined neutral pixel value, including the adjunct content within a compensating image by setting a pixel value of a third group of pixels included in the compensating image and corresponding to the first and second groups of pixels to be less than the predetermined neutral pixel value, and presenting the first image, the second image, and the compensating image. Corresponding methods and systems are also disclosed.

    • Disclosed is a computer audio interface adapted to enable blind or visually impaired users to locate icons positioned in rows in the background of a graphical user interface. Whenever the pointer of the interface is positioned on the background, the system produces a distinctive tone. Whenever the pointer is positioned in an icon row that is occupied by one or more icons, the system produces a distinctive chord. Whenever the pointer is positioned in the background and not in an occupied row, the system produces stereo effects that give the user information as to the relative left/right position of the pointer. Whenever the pointer is positioned in an occupied row, the amplitude of the left and right stereo channels is controlled such that whenever the pointer is to the left of the leftmost icon, substantially all of the volume is produced by the left speaker and whenever the pointer is to the right of the rightmost icon, substantially all of the the volume is produced by the right speaker. Whenever the pointer is located between the leftmost and rightmost icons, the volume is balanced substantially equally between the two speakers.
    • 公开了一种计算机音频接口,其适于使盲人或视觉受损用户能够定位在图形用户界面的背景中的行中定位的图标。 每当接口的指针位于背景上时,系统将产生独特的音调。 每当指针位于由一个或多个图标占据的图标行中时,系统产生独特的和弦。 每当指针位于背景中而不是在占用行中时,系统产生立体声效果,其给予用户关于指针的相对左/右位置的信息。 每当指针位于占用行中时,左右立体声通道的振幅被控制,使得每当指针在最左边的图标的左侧时,基本上所有的音量都由左扬声器产生,并且每当指针 在最右边的图标的右侧,大部分的音量都是由右侧扬声器产生的。 每当指针位于最左侧和最右边的图标之间时,两个扬声器之间的音量基本相等。

    • A direct measurement technique is disclosed for determining baseband frequency response of an FM transmitter without using response-altering test devices otherwise injecting frequency dependent characteristics, such as pre-emphasis networks and demodulators. The technique enables absolute, universal standardization. Variations in a sideband amplitude in the output spectrum from the FM transmitter unit under test are monitored while changing the frequency and controlling the amplitude of the modulating signal so as to maintain a constant modulation index B. A signal generator supplies the modulating signal directly to the FM transmitter without frequency dependent pre-emphasis. A spectrum analyzer directly examines the output spectrum of the FM transmitter without demodulation.
