20080232478 | Methods of Performing Error Concealment For Digital Video - Error concealment is used to hide the effects of errors detected within digital video information. A complex error concealment mode decision is disclosed to determine whether spatial error concealment (SEC) or temporal error concealment (TEC) should be used. The error concealment mode decision system uses different methods depending on whether the damaged frame is an intra-frame or an inter-frame. If the video frame is an intra-frame then a similarity metric is used to determine if the intra-frame represents a scene-change or not. If the video frame is an intra-frame, a complex multi-termed equation is used to determine whether SEC or TEC should be used. A novel spatial error concealment technique is disclosed for use when the error concealment mode decision determines that spatial error concealment should be used for reconstruction. The novel spatial error concealment technique divides a corrupt macroblock into four different regions, a corner region, a row adjacent to the corner region, a column adjacent to the corner region, and a remainder main region. Those regions are then reconstructed in that order and information from earlier reconstructed regions may be used in later reconstructed regions. Finally, a macroblock refreshment technique is disclosed for preventing error propagation from harming non-corrupt inter-blocks. Specifically, an inter-macroblock may be ‘refreshed’ using spatial error concealment if there has been significant error caused damage that may cause the inter-block to propagate the errors. | 2008-09-25 |

The teleconference bridge of the illustrative embodiment continually receives geo-location information about the cell phone. Based on the geo-location of the cell phone relative to the position of the speakerphone, the bridge determines whether to include or exclude signals that are received from the cell phone when preparing a signal for transmission to the speakerphone during a conference call. The bridge also determines whether to refrain from transmitting an audio signal to the cell phone, when the bridge infers that the cell phone is being used as a satellite microphone, such as when the cell phone is placed on a conference room table. As a result, each conference call participant is able to use his or her own cell phone as a personal satellite microphone, which can improve the sound quality of the conference call. | 2008-09-25 |

20080232573 | User-Programmable Call Progress Tone Detection - A telecommunications system is disclosed that enables a telecommunications switch to be “user” programmable in the “field”—in contrast to only programmable by the manufacturer or third-party software company—with audio samples. Each audio sample is exemplar of a sound that might be encountered during or after the establishment of a telecommunications call that is handled by the telecommunications switch. In accordance with the illustrative embodiment, the audio samples are received by the telecommunications switch through one or more of the same ports that the telecommunications switch uses to route calls, in contrast to programs and program data that are received by the telecommunications switch through a programming port. | 2008-09-25 |
