| 20100124321 | System and method for dynamic audio conference call configuration and management - A new approach is proposed that contemplates audio conference systems and methods to expand the capacity a conference call by utilizing both a mixing engine that enables a first group participants to be able to both listen to and speak at the conference call, and a broadcast engine that broadcasts the conference call to a second group of participants who are only interested in listening to, but not speaking at the conference call. During the conference call, participants at the mixing engine and the broadcast engine can be dynamically adjusted. | 05-20-2010 |
| 20100262267 | Systems and methods for computer and voice conference audio transmission during conference call via PSTN phone - A new approach is proposed that contemplates systems and methods to support canceling audio streams leaked from a speaker to a PSTN so that only the audio stream of a presenter or viewer speaking at a conference call is transmitted. Here, the audio streams being canceled includes the audio stream of an application being run or a material being presented online during a web conference. The voice audio stream of a presenter or viewer is then transmitted in addition to the computer audio stream, clean from any other audio stream of echoes or feedbacks captured by the hosting device during the conference call. | 10-14-2010 |
| 20100262268 | Systems and methods for computer and voice conference audio transmission during conference call via VOIP device - A new approach is proposed that contemplates systems and methods to support canceling audio streams leaked from a speaker to a microphone so that a clean audio stream of a presenter or viewer speaking at a conference call is transmitted. Here, the audio streams being canceled includes the computer audio stream of an application being run or a material being presented online during a web conference and/or the audio stream received from the rest of the group of participants at the conference call. The computer audio stream is then transmitted in addition to the presenter or viewer audio stream, and separate from any other audio stream captured by the hosting device during the conference call. | 10-14-2010 |
| 20100262656 | Systems and methods for computer and voice conference audio transmission during conference call via VoIP device - A new approach is proposed that contemplates systems and methods to support canceling audio streams leaked from a speaker to a microphone so that a clean audio stream of a presenter or viewer speaking at a conference call is transmitted. Here, the audio streams being canceled includes the computer audio stream of an application being run or a material being presented online during a web conference and/or the audio stream received from the rest of the group of participants at the conference call. The computer audio stream is then transmitted in addition to the presenter or viewer audio stream, and separate from any other audio stream captured by the hosting device during the conference call. | 10-14-2010 |
| 20110019810 | Systems and methods for switching between computer and presenter audio transmission during conference call - A new approach is proposed that contemplates systems and methods to support switching between computer audio and presenter audio during a conference call so that one and only one, not both, of the two audio streams is being transmitted to the rest of the conference at any time. More specifically, a switch engine is adopted, which separately takes one or more audio streams captured by a sound mixing component of the hosting device of a presenter and by a microphone attached to the hosting device as its two inputs, and outputs only one of the two inputs at any time. The selected audio output is then processed and transmitted to the rest of the conference with feedback from other audio sources canceled. | 01-27-2011 |
| 20110150433 | Systems and methods for video-aware screen capture and compression - A new approach is proposed that contemplates systems and methods to support video-aware screen capture and compression. More specifically, the video-aware approach first detects whether or when video content is being actively played back on a screen of a hosting device. If the video content is actively being rendered, the approach separates (segments) the screen content into static (non-video) content and video content, The approach then applies video-specific capture and compression methods to the video content of the screen and other suitable compression methods to the non-video content of the screen. The compressed static and video content of the screen are separately and independently transmitted across the network to remote computing devices and are then decompressed and processed to reconstruct screen of its original content for display at the screens of the remote computing devices. | 06-23-2011 |
| 20110246761 | Systems and methods for distributed media stream transcoding and sharing - A new approach is proposed that contemplates systems and methods to support distributed stream media transcoding and sharing in real time. Under the approach, a host associated with a sender generates a high quality stream of media content that is to be shared with a plurality of viewers over a communication network. The hosting devices associated with the plurality of viewers are evaluated for their capability to process and/or transcode the high quality media stream. Based on the evaluation, the host of the sender encodes and transmits the high quality media stream to at least one selected host associated a viewer. Besides decoding the received high quality media stream and displaying it for its own consumption, the selected host of the sender further transcodes the media stream by re-encoding the high quality media steam into a different, probably lower quality media stream, and transmits the re-encoded media stream to a mobile device associated with another viewer, which then decodes and displays the lower quality media stream on the mobile device. | 10-06-2011 |
| 20120143955 | METHODS AND SYSTEMS FOR BANDWIDTH ADAPTIVE N-TO-N COMMUNICATION IN A DISTRIBUTED SYSTEM - Methods and systems for bandwidth adaptive computing device to computing device communication are described. Bandwidth adaptive communication includes receiving a communication from a first participant, storing the payload data of the communication in a channel memory element associated with the first participant, and transmitting the payload data to a second participant. | 06-07-2012 |
