  • Patent number: 9503812
    Abstract: Systems and methods for performing videoconferencing using split endpoints are disclosed herein. These endpoints can include a Main Unit and a Satellite Unit that are associated with each other, and where the tasks of video and audio encoding and decoding are separated between the two. In some embodiments the Main Unit performs video and audio encoding, and the Satellite Unit performs video and audio decoding. In some embodiments the Satellite Unit obtains media data through its associated Main Unit, whereas in other embodiments the Satellite Unit obtains media data directly from the Server.

  • Publication number: 20160255307
    Abstract: Systems and methods for conducting a multi-endpoint video signal conference are provided. Conferencing endpoints are linked by pairs of a reliable and a less reliable communication channel. Conference video signals are scaleable coded in base layer and enhancement layers format. Video signal base layers, which correspond to a minimum picture quality, are communicated over reliable channels. The video signal enhancements layers may be communicated over the less reliable channels. A conference server mediates the switching of video layer information from transmitting endpoints to receiving endpoints without any intermediate coding or re-coding operations. The video conference can be integrated with an audio conference using either scalable coded audio signals or non-scaleable coded audio signals.

  • Patent number: 9426536
    Abstract: Techniques for delivery and presentation/display of audio-visual signals over electronic communications network channels are disclosed herein. In an exemplary embodiment, a video server for an IPTV system is disclosed. The system includes a video extractor/transporter (shortly referred to as video extractor) for extracting encoded audio-visual signals from at least one video source, and distributing the signals over the electronic communications network channels. The system also includes control logic which can receive control messages from receivers and invoke the video extractor to extract audio-visual signals therefrom.

  • Patent number: 9307199
    Abstract: Systems and methods for error resilient transmission, rate control, and random access in video communication systems that use sealable video coding are provided. Error resilience is obtained by using information from low resolution layers to conceal or compensate loss of high resolution layer information. The same mechanism is used for rate control by selectively eliminating high resolution layer information from transmitted signals, which elimination can be compensated at the receiver using information from low resolution layers. Further, random access or switching between low and high resolutions is also achieved by using information from low resolution layers to compensate for high resolution spatial layer packets that may have not been received prior to the switching time.

  • Patent number: 9179160
    Abstract: Systems and methods for error resilient transmission and for random access in video communication systems are provided. The video communication systems are based on single-layer, scalable video, or simulcast video coding with temporal scalability, which may be used in video communication systems. A set of video frames or pictures in a video signal transmission is designated for reliable or guaranteed delivery to receivers using secure or high reliability links, or by retransmission techniques. The reliably-delivered video frames are used as reference pictures for resynchronization of receivers with the transmitted video signal after error incidence and for random access.

  • Patent number: 9055312
    Abstract: The present invention provides techniques for digital video distribution that provides for joint video content watching amongst a group of watchers using multiple mini browsing windows (MBWs), such that the watchers can simultaneously interact with each other in a video conferencing-like setting (i.e., seeing selected watchers' videos in MBWs and hearing their voices) while they view together specific video content in a synchronized way. The MBWs can be displayed as overlays on the main video window being watched on full screen.

  • Publication number: 20150035940
    Abstract: Systems and methods for the integration of audio and video communication systems with gaming systems are disclosed herein. In one embodiment of the present disclosure, the audio and video communication server uses information from the game engine in order to decide which users are in virtual proximity to a particular user so that it only forwards their audio to the particular user. In another embodiment, additional audio composition streams are associated with the user's audio streams so that they are rendered at receiving endpoints with the spatial positioning intended by the game engine.
