摘要： A multimedia server distributes closed captioning over a network to a client device running a media player that does not support standardized closed captioning. The multimedia server receives a media stream including closed captioning that is encoded according to a closed captioning standard such as Consumer Electronics Association CEA-608-B or CEA 708-B, Advanced Television Systems Committee ATSC A/53 or the Society of Cable Telecommunications Engineers SCTE 20 and/or SCTE 21. The multimedia server transcodes the closed captioning into a format that is usable by the media player and transmits the transcoded closed captioning to the client device over the network so that the media player can render the closed captioning synchronously with programming content included in the media stream.

摘要： An arrangement for simulating a short depth of field in a captured videophone image is provided in which the background portion of the image is digitally segregated and blurred to render it indistinct. Thus, the displayed video of a user in the foreground is kept in focus while the background appears to be out of focus. Image tracking or fixed templates are used to segregate an area of interest that is kept in focus from the remaining captured video image. Image processing techniques are applied to groups of pixels in the remaining portion to blur that portion of the captured video image. Such techniques include the application of a filter that are alternatively selected from convolution filters in the spatial domain (e.g., mean, median, or Gaussian filters), or frequency filters in the frequency domain (e.g., low-pass or Gaussian filters). User-selectable control is optionally implemented for controlling the type of foreground/background segregation technique utilized (i.e., dynamic face-tracking or fixed template shape), degree of blurring applied to the background, and on/off control of the background blurring.
摘要翻译：提供了一种用于模拟捕获的可视电话图像中的短景深的布置，其中图像的背景部分被数字地分离和模糊以使其不清楚。因此，前景中的用户的显示的视频被保持焦点，而背景看起来是失焦的。图像跟踪或固定模板用于将保留在焦点的感兴趣区域与剩余的捕获视频图像隔离。图像处理技术被应用于剩余部分中的像素组，以模糊捕获的视频图像的该部分。这样的技术包括应用在空间域（例如，平均值，中值或高斯滤波器）中的卷积滤波器或频域中的频率滤波器（例如，低通滤波器或高斯滤波器）备选地选择的滤波器。可选地实施用户可选择的控制以控制所使用的前景/背景分离技术的类型（即，动态面部跟踪或固定模板形状），应用于背景的模糊程度以及背景模糊的开/关控制。
