| 20110122314 | SYSTEM FOR GENERATING CLOSED CAPTIONING COMPATIBLE WITH LEGACY AND NEWER SET-TOP BOXES - A caption formatting method and computing system that receives an input video stream that includes a sequence of input transport stream packets. The method locates user data in the sequence of input transport stream packets, where the user data includes input caption data compliant with an input caption data format. The method extracts EIA-608 captions and EIA-708 captions from the input caption data, and formats the EIA-608 captions as caption data compliant with SCTE-20 format. The method creates a sequence of output transport stream packets based on the sequence of input transport stream packets, where the sequence of output transport stream packets include the caption data compliant with SCTE-20 format and the input caption data. The method sends an output video stream from the computing device, where the output video stream includes the sequence of output transport stream packets. | 05-26-2011 |

| 20080259154 | Simulating Short Depth of Field to Maximize Privacy in Videotelephony - 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. | 10-23-2008 |

| 20100082734 | Establishing A Thin Client Terminal Services Session - An encrypted credential is received from a client terminal, where the encrypted credential is based on encryption of an authentication credential input by a user at the client terminal for allocating resources from a central server, the resources to provide a thin client terminal services session. A thin client terminal services session is established between the client terminal and the central server using the allocated resources, where establishing the thin client terminal services session include receiving a decryption key from a remote system, and decrypting the encrypted credential using the decryption key. | 04-01-2010 |
