| 20120069137 | Synchronization and Mixing of Audio and Video Streams in Network-Based Video Conferencing Call Systems - In one aspect, audio streams are added to a mix until the mix is either complete (i.e., all audio streams have been added) or the mix is closed early (i.e., before the mix is complete). In another aspect, audio and video streams are synchronized by playing back the audio stream and then synchronizing display of the video frames to the playback of the audio stream. | 03-22-2012 |
| 20100325209 | Efficient Network Routing To Reduce Bandwidth Usage and Latency - A method (and corresponding system and computer program product) for efficiently routing a multi-person conference to reduce bandwidth usage and latency is described. Computing devices used by the participants to participate in the conference are separated into proximity pools based on direct accessibility. For each proximity pool, a computing device is selected as the key node. Only the key node communicates directly with a server, and redistributes data received from the server to its pool peers. Communications between computing devices within a same pool are routed directed to one another. Proximity pools can be refined to factor in distances among the computing devices. Multiple servers may be used to reduce latency. Proximity pools are assigned to nearby servers. Communications between computing devices in different proximity pools are routed through the server(s) associated with the different proximity pool. | 12-23-2010 |
| 20100271457 | Advanced Video Conference - Methods (and corresponding systems and computer program products) providing (1) flexible controls for the number of users that register and use a system, (2) flexible group contact management control, and (3) establishing a caller's video on each receiver's screen as soon as the caller makes a video conference call. | 10-28-2010 |
| 20100188476 | Image Quality of Video Conferences - A method (and corresponding system and computer program product) providing high image quality video conferences at low network bandwidth usage. Video images are captured at a high resolution and downsampled to a low resolution before transmitted over a network. When the downsampled video images are received, they are upconverted back to higher resolution video images. The upconverted video images are then transmitted to a display device via a High-Definition Multimedia Interface (HDMI) output, and displayed on the display device. | 07-29-2010 |
| 20090089683 | SYSTEMS AND METHODS FOR ASYNCHRONOUSLY JOINING AND LEAVING VIDEO CONFERENCES AND MERGING MULTIPLE VIDEO CONFERENCES - A method (and corresponding system and computer program product) providing control to open video conference is disclosed. One aspect enables participants of a video conference to asynchronously join and leave the video conference. Another aspect enables participants to merge multiple video conferences into a single video conference, or to split a single video conference into multiple video conferences. | 04-02-2009 |
| 20090086012 | RECORDING AND VIDEOMAIL FOR VIDEO CONFERENCING CALL SYSTEMS - In one aspect, a request to initiate a video conference is received from a caller. The request identifies one or more called parties for the video conference. A request for the video conference is sent to one of the called parties. The called party does not accept the request. In response to a lack of acceptance of the request by the called party, a videomail service is provided. A videomail message from the caller is recorded. The caller is the sender of the videomail message and the called party is the recipient of the videomail message. The called party is notified that he has a videomail message. | 04-02-2009 |
