20110013904 | PASSIVE OPTICAL NETWORK (PON) IN-BAND OPTICAL TIME DOMAIN REFLECTOMETER (OTDR) - An in-band OTDR uses a network's communication protocols to perform OTDR testing on a link. Because the OTDR signal (probe pulse) is handled like a data signal, the time required for OTDR testing is typically about the same as the time required for other global network events, and is not considered an interruption of service to users. A network equipment includes an optical time domain reflectometry (OTDR) transmitter and receiver, each operationally connected to a link to transmit and receive, respectively, an OTDR signal. When an OTDR is to be performed, a network device operationally connected to the link actuates the OTDR transmitter to transmit the OTDR signal on the link during a determined test time based on a communications protocol of the link, during which data signals are not transmitted to the network equipment. A processing system processes the OTDR signal to provide OTDR test results. | 01-20-2011 |

20120148236 | IN-BAND CONTROL MECHANISM - A method and apparatus of managing remote third party OTN & WDM transceiver equipment using the same fibers used for end user data exchange is described. A network device collects management instructions for the OTN & WDM transceiver equipment, assembles this management information into the overhead of a data frame and transmits on an optical link directly coupled to the network device. The WDM transceiver function converts the optical signal to an electrical one and the OTN function extracts the management instructions from the OTN overhead. A processor associated with the OTN framer function acts on that information. The management instructions includes the instruction to periodically and continuously, load certain performance, alarm or informational data into its OTN overhead and transmit that to a similar transceiver at the remote end of the communications link. Network-based monitoring equipment can optically tap off a portion of the signal and extract this information, allowing the network-based device to gain knowledge of conditions at the end points. | 06-14-2012 |

20090178098 | SYSTEM FOR REMOTELY CONTROLLING CLIENT RECORDING AND STORAGE BEHAVIOR - A system for remotely controlling client recording and storage behavior schedules the recording, storing, and deleting of multimedia content on a client system storage device. The invention accepts as input a prioritized list of program viewing preferences which is compared with a database of program guide objects that indicate when programs of interest are actually broadcast. A schedule of time versus available storage space is generated that is optimal for the viewer's explicit or derived preferred content. The viewer may request that certain content be captured, which results in the highest possible priority for those content.

20130016102 | SIMULATING THREE-DIMENSIONAL FEATURES - Image information displayed on an electronic device can be modified based at least in part upon a relative position of a user with respect to a device. Mapping, topological or other types of positional data can be used to render image content from a perspective that is consistent with a viewing angle for the current relative position of the user. As that viewing angle changes, as a result of movement of the user and/or the device, the content can be re-rendered or otherwise updated to display the image content from a perspective that reflects the change in viewing angle. Simulations of effects such as parallax and occlusions can be used with the change in perspective to provide a consistent user experience that provides a sense of three-dimensional content even when that content is rendered on a two-dimensional display. Lighting, shading and/or other effects can be used to enhance the experience. | 01-17-2013 |
