Embodiment Construction

[0042] A detailed description of the exemplary embodiments will now be described with reference to different drawings. While this description provides detailed examples of possible implementations, it should be noted that the details are exemplary and not intended to limit the scope of application.

[0043] Figure 1Ais a diagram of an example communication system 100 in which one or more disclosed embodiments may be implemented. Communication system 100 may be a multiple access system for providing content, such as voice, data, video, messaging, broadcast, etc., to multiple wireless users. The communication system 100 enables multiple wireless users to access such content by sharing system resources, including wireless bandwidth. For example, communication system 100 may use one or more channel access methods such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal FDMA (OFDMA), Single Carrier ...

Abstract

A device may control a video communication via transcoding and / or traffic shaping. The device may include a multipoint control unit (MCU) and / or a server. The device may receive one or more video streams from one or more devices. The device may analyze a received video stream to determine a viewing parameter. The viewing parameter may include a user viewing parameter, a device viewing parameter, and / or a content viewing parameter. The device may modify a video stream based on the viewing parameter. Modifying the video stream may include re-encoding the video stream, adjusting an orientation, removing a video detail, and / or adjusting a bit rate. The device may send the modified video stream to another device. The device may determine a bit rate for the video stream based on the viewing parameter. The device may indicate the bit rate by sending a feedback message and / or by signaling a bandwidth limit.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application No. 61 / 871,836, filed August 29, 2013, and U.S. Provisional Application No. 61 / 944,548, filed February 25, 2014, the contents of which are hereby combined for reference. Background technique [0003] Video telephony is a growing segment of traffic carried over wireless networks. This trend is expected to continue, evidenced by the introduction of support for Apple's FaceTime technology delivered over LTE networks. Video telephony systems can be integrated in web browsers without third-party plug-ins. The mobile video telephony system may not take the visual link into consideration in the process of capturing and processing the video data. [0004] Real-time video telephony over wireless networks is characterized by significant bandwidth and latency requirements. Due to the low tolerance to delays in interactive sessions such as video chats, buffering...
