Abstract: Content is shared by rendering the content in a shared session and providing the rendered content to the participating devices. The originating device has access to an original version of the content in a virtual session, which is accessed by logging into cloud content services and downloading the desired content into the virtual session. A rendering engine in a rendered session then renders the content and distributes the rendered content to the participants. Only rendered content is provided to the participants, so that the participants cannot see the credentials of the originating user, cannot see the document source and do not have access to the document itself. The participants can mark up the rendered content, which markups are shared to the other participants.

Abstract: A videoconference apparatus at a first location detects audio from a location and determines whether the sound should be included in an audio-video stream sent to a second location, or excluded as an interfering noise. Determining whether to include the audio involves using a face detector to see if there is a face at the source of the sound. If a face is present, the audio data from the location will be transmitted to the second location. If a face is not present, additional motion checks are performed to determine whether the sound corresponds to a person talking, (such as a presenter at a meeting), or whether the sound is instead unwanted noise.

Abstract: A system and method provide a rule-based technique for adapting a videoconferencing system to current conditions of a conference session, automatically converting the session from one conferencing technique to another, based on those current conditions. Rules may involve criteria including number of participants, ability to use a common codex, among others. An escalation module can be used to manage the transition between one type of conference session and another. If a condition occurs that causes transitioning the conference from one type to another, when that condition no longer applies, the conference may automatically transition back to the original conferencing type.

Abstract: A system for ensuring that the best available view of a person's face is included in a video stream when the person's face is being captured by multiple cameras at multiple angles at a first endpoint. The system uses one or more microphone arrays to capture direct-reverberant ratio information corresponding to the views, and determines which view most closely matches a view of the person looking directly at the camera, thereby improving the experience for viewers at a second endpoint.

Abstract: Blurriness in a video image transmitted over a lossy network can be reduced by filtering the decoder output to determine whether updating of the reference frame based on the current video data is indicated. An update may be appropriate if the decoder output is sharper than the contents of the display buffer after the last update. Additionally, an update may be appropriate if there was a significant change to the underlying image, and thus to the encoder's input. Whether such a change has occurred can be determined by analyzing the prediction mode, motion vectors, and pixel data of the output image.

Abstract: A novel universal bridge (UB) can handle and conduct multimedia multipoint conferences between a plurality of MREs and LEPs without using an MRM, an MCU and a gateway. Further, a UB can be configured to allocate and release resources dynamically according to the current needs of each conferee and the session.

Abstract: A striped composed video image is disclosed, in which a main segment image is displayed with a strip of small strip segments. The strip of small strip segments is composed from a plurality of video images from a plurality of video streams. A user may pull video from the strip into the main segment. The strip of small strip segments may scrolled without affecting the main segment.

Abstract: A videoconferencing endpoint includes at least one processor a number of microphones and at least one camera. The endpoint can receive audio information and visual motion information during a teleconferencing session. The audio information includes one or more angles with respect to the microphone from a location of a teleconferencing session. The audio information is evaluated automatically to determine at least one candidate angle corresponding to a possible location of an active talker. The candidate angle can be analyzed further with respect to the motion information to determine whether the candidate angle correctly corresponds to person who is speaking during the teleconferencing session.

Abstract: Content presented in association with a transmitting endpoint is obtained by the transmitting endpoint and transmitted to a receiving endpoint of a videoconference, along with associated information regarding interaction of a presenter with the content at the transmitting side. The receiving endpoint presents the presented content obtained from the transmitting endpoint similar to the presentation format at the transmitting side. Where the original presentation format is not suitable for transmission, a video image of the content in the original presentation format may be transmitted. An intermediate control unit, such as a multipoint control unit, may relay content and associated information between transmitting and receiving endpoints.
