Abstract: Some embodiments provide a method for initiating a video conference using a first mobile device. The method presents, during an audio call through a wireless communication network with a second device, a selectable user-interface (UI) item on the first mobile device for switching from the audio call to the video conference. The method receives a selection of the selectable UI item. The method initiates the video conference without terminating the audio call. The method terminates the audio call before allowing the first and second devices to present audio and video data exchanged through the video conference.

Abstract: A method and system for caching and streaming media content, including predictively delivering and/or acquiring content is provided. In the system, client devices may be communicatively coupled in a network, and may access and share cached content. Video segments making up a media stream may be selectively delivered to the clients such that a complete media stream may be formed from the different segments delivered to the different clients. Video segments may be pushed by the server to the client or requested by the client according to a prioritization scheme, including downloading: partial items on a client's subscription log, lower quality version(s) of content before higher quality version(s), higher bitrate segments before lower bitrate segments, summaries of full-length content, advertisements and splash screens common to multiple video clips.

Abstract: Systems and processes for improved video editing, summarization and navigation based on generation and analysis of metadata are described. The metadata may be content-based or non-content-based and used to prioritize and/or classify portions of video. The metadata may be generated at the time of image capture or during post-processing. Prioritization information, such as a score for various portions of the image data may be based on the metadata and/or image data. Classification information such as the type or quality of a scene may be determined based on the metadata and/or image data. The classification and prioritization information may be metadata and may be used to automatically remove undesirable portions of the video, generate suggestions during editing or automatically generate summary video.

Abstract: [69] Techniques for coding video data estimate depths of different elements within video content (310) and identify regions within the video content based on the estimated depths (320). One of the regions may be assigned as an area of interest (330). Thereafter, video content of a region that is not an area of interest may be masked out (340) and the resultant video content obtained from the masking may be coded (350). The coded video content may be transmitted to a channel (360). 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（310）内的不同元素的深度，并基于估计的深度（320）识别视频内容内的区域。 其中一个区域可以被分配为感兴趣的区域（330）。 此后，可以屏蔽不是感兴趣区域的区域的视频内容（340），并且可以对从屏蔽获得的结果视频内容进行编码（350）。 编码的视频内容可以被发送到频道（360）。 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。

Abstract: Systems and methods are presented for minimizing the suddenness and immediacy of changes to the video quality perceived by users due to bandwidth fluctuations and transitions between different bitrate streams. A method may include identifying an upcoming bitrate change in a bitstream and a nearest scene cut boundary from sync frame scene cut tags included in the bitstream. The method may include calculating whether waiting until the identified nearest scene cut boundary before changing the bitrate will cause the buffer to drop below a threshold. When the buffer is calculated to not drop below the threshold, the method may postpone the upcoming bitrate change until the identified nearest scene cut boundary.
