| 20110292164 | Systems, methods, and media for identifying and selecting data images in a video stream - Systems, methods, and media for identifying and selecting data images in a video stream are provided. In accordance with some embodiments, methods for identifying and selecting data images in a video stream are provided, the methods comprising: receiving a video bit stream representing a plurality of images; identifying, using a processor programmed to do so, sets of data images in the plurality of images, wherein each of the data images provides an image representation of data and each of the data images in any of the sets of data images corresponds to a single data image; and selecting at least one best data image from the sets of data images using a processor programmed to do so. | 12-01-2011 |
| 20110153735 | INITIATION AND SUPPORT OF VIDEO CONFERENCING USING INSTANT MESSAGING - A system and method for initiating and supporting network video conferences are disclosed. In accordance with the invention, one or more instant messaging enabled clients can initiate a video conference. At least a pair of client nodes communicate with each other via an instant messaging utility. An instant messaging server supports instant messages between the two client nodes. A second server, e.g., a video conferencing server, supports video conferences between video conference participants, a video conference being initiated between video conference participants in response to an instant message transmitted between the at least two client nodes. | 06-23-2011 |
| 20110016204 | SYSTEMS, METHODS, AND MEDIA FOR IDENTIFYING AND ASSOCIATING USER DEVICES WITH MEDIA CUES - Systems, methods, and media for identifying and associating user devices with media cues are provided. In some embodiments, a plurality of data streams from a plurality of endpoints is received. At least one media segment is then received from a user device. It is determined whether the at least one media segment from the user device corresponds with one of the plurality of data streams from the plurality of endpoints. In response to being unable to match the at least one media segment, a media cue is inserted into one of the plurality of data streams. In response to detecting that the media cue in that data stream is received by the user device, identification information is transmitted to the user device that associates the user device with one or more services on a communications server. | 01-20-2011 |
| 20100066807 | INITIATION AND SUPPORT OF VIDEO CONFERENCING USING INSTANT MESSAGING - A system and method for initiating and supporting network video conferences are disclosed. In accordance with the invention, one or more instant messaging enabled clients can initiate a video conference. At least a pair of client nodes communicate with each other via an instant messaging utility. An instant messaging server supports instant messages between the two client nodes. A second server, e.g., a video conferencing server, supports video conferences between video conference participants, a video conference being initiated between video conference participants in response to an instant message transmitted between the at least two client nodes. | 03-18-2010 |
| 20090051754 | Methods for Reducing Call Set Up Times Using Automatic Connection Negotiation - Methods and products for reducing the time required to set-up a call are provided. In particular, new functionality to H.324 is added by allowing the transmission of media to commence after a reduced number of H.245 messages have been exchanged by two calling devices. If two terminals involved in a call are capable of automatic connect renegotiation, one or more predetermined logical channels in the two terminals for transmitting media is selected, a message is sent from one terminal to the other terminal to open the predetermined logical channel, and media transmission between the two terminals is commenced. | 02-26-2009 |
