Abstract: In video conferencing over a radio network, the radio equipment is a major power consumer especially in cellular networks such as LTE. In order to reduce the radio power consumption in video conferencing, it is important to introduce an enough radio inactive time. Several types of data buffering and bundling can be employed within a reasonable range of latency that doesn't significantly disrupt the real-time nature of video conferencing. In addition, the data transmission can be synchronized to the data reception in a controlled manner, which can result in an even longer radio inactive time and thus take advantage of radio power saving modes such as LTE C-DRX.

Abstract: Computing devices may implement instant video communication connections for video communications. Connection information for mobile computing devices may be maintained. A request to initiate an instant video communication may be received, and if authorized, the connection information for the particular recipient mobile computing device may be accessed. Video communication data may then be sent to the recipient mobile computing device according to the connection information so that the video communication data may be displayed at the recipient device as it is received. New connection information for different mobile computing devices may be added, or updates to existing connection information may also be performed. Connection information for some mobile computing devices may be removed.

Abstract: An apparatus and method for detecting and analyzing spikes in network jitter and the estimation of a jitter buffer target size is disclosed. Detected spikes may be classified as jump spikes or slope spikes, and a clipped size of detected spikes may be used in the estimation of the jitter buffer target. Network characteristics and conditions may also be used in the estimation of the jitter buffer target size. Samples may be modified during playback adaptation to improve audio quality and maintain low delay of a receive chain.

Abstract: Computing devices may implement dynamic display of video communication data. Video communication data for a video communication may be received at a computing device where another application is currently displaying image data on an electronic display. A display location may be determined for the video communication data according to display attributes that are configured by the other application at runtime. Once determined, the video communication data may then be displayed in the determined location. In some embodiments, the video communication data may be integrated with other data displayed on the electronic display for the other application.

Abstract: Computing devices may implement dynamic transitions from video messages to video communications. Video communication data for a video message may be received at a recipient device. The video communication data may be displayed as it is received, and recorded for subsequent playback. An indication of a selection to establish a video communication with the sender of the video message may be received, or an indication that display of the video communication is to be ceased may be received. If a video communication is to be established, then a video communication connection with the sender of the video message may be created so that subsequent video communication data may be sent via the established connection.

Abstract: Techniques for coding video data estimate depths of different elements within video content and identify regions within the video content based on the estimated depths. One of the regions may be assigned as an area of interest. Thereafter, video content of a region that is not an area of interest may be masked out and the resultant video content obtained from the masking may be coded. The coded video content may be transmitted to a channel. These techniques permit a coding terminal to mask out captured video content prior to coding in order to support coding policies that account for privacy interests or video composition features during a video coding session.
Abstract translation: 用于编码视频数据的技术估计视频内容中的不同元素的深度，并基于估计的深度识别视频内容内的区域。 其中一个地区可能被分配为感兴趣的区域。 此后，可以屏蔽不是感兴趣区域的区域的视频内容，并且可以对从屏蔽获得的结果视频内容进行编码。 编码的视频内容可以被发送到频道。 这些技术允许编码终端在编码之前掩蔽捕获的视频内容，以便在视频编码会话期间支持考虑隐私兴趣或视频合成特征的编码策略。
