Abstract: A method for processing media assets includes, given a first media asset, deriving characteristics from the first media asset, searching for other media assets having characteristics that correlate to the characteristics of the first media asset, when a match is found, deriving content corrections for the first media asset or a matching media asset from the other of the first media asset or the matching media asset, and correcting content of the first media asset or the matching media asset based on the content corrections.

Abstract: Coding techniques for image data may cause a still image to be converted to a “phantom” video sequence, which is coded by motion compensated prediction techniques. Thus, coded video data obtained from the coding operation may include temporal prediction references between frames of the video sequence. Metadata may be generated that identifies allocations of content from the still image to the frames of the video sequence. The coded data and the metadata may be transmitted to another device, whereupon it may be decoded by motion compensated prediction techniques and converted back to a still image data. Other techniques may involve coding an image in both a base layer representation and at least one coded enhancement layer representation. The enhancement layer representation may be coded predictively with reference to the base layer representation. The coded base layer representation may be partitioned into a plurality of individually-transmittable segments and stored. Prediction references of elements of the enhancement layer representation may be confined to segments of the base layer representation that correspond to a location of those elements. Meaning, when a pixel block of an enhancement layer maps to a given segment of the base layer representation, prediction references are confined to that segment and do not reference portions of the base layer representation that may be found in other segment(s).
Abstract translation: 用于图像数据的编码技术可以使静止图像被转换成通过运动补偿预测技术编码的“幻影”视频序列。 因此，从编码操作获得的编码视频数据可以包括视频序列的帧之间的时间预测参考。 可以生成元数据，其识别从静止图像到视频序列的帧的内容的分配。 编码数据和元数据可以被发送到另一个设备，于是可以通过运动补偿预测技术对其进行解码并转换成静止图像数据。 其他技术可以包括在基本层表示和至少一个编码的增强层表示中对图像进行编码。 增强层表示可以参考基本层表示预测地编码。 编码的基本层表示可以被划分成多个可单独传送的段并被存储。 增强层表示的元素的预测参考可以被限制为对应于那些元素的位置的基本层表示的段。 意思是，当增强层的像素块映射到基本层表示的给定段时，预测参考限于该段，并且不引用可能在其他段中找到的基本层表示的部分。

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: Computing devices may implement dynamic detection of pause and resume for video communications. Video communication data may be capture at a participant device in a video communication. The video communication data may be evaluated to detect a pause or resume event for the transmission of the video communication data. Various types of video, audio, and other sensor analysis may be used to detect when a pause event or a resume event may be triggered. For triggered pause events, at least some of the video communication data may no longer be transmitted as part of the video communication. For triggered resume events, a pause state may cease and all of the video communication data may be transmitted.

Abstract: Methods and systems provide efficient sample adaptive offset (SAO) signaling by reducing a number of bits consumed for signaling SAO compared with conventional methods. In an embodiment, a single flag is used if a coding unit to a first scanning direction with respect to a given coding unit is off. In an embodiment, further bits may be saved if some neighboring coding units are not present, i.e. the given coding unit is an edge. For example, a flag may be skipped, e.g., not signaled, if the given coding unit does not have a neighbor. In an embodiment, a syntax element, one or more flags may signal whether SAO filtering is performed in a coding unit. Based on the syntax element, a merge flag may be skipped to save bits. In an embodiment, SAO syntax may be signaled at a slice level.
Abstract translation: 方法和系统通过减少与常规方法相比信号SAO消耗的比特数来提供有效的采样自适应偏移（SAO）信令。 在一个实施例中，如果关于给定编码单元的第一扫描方向的编码单元关闭，则使用单个标志。 在一个实施例中，如果一些相邻编码单元不存在，即给定的编码单元是边缘，则可以节省进一步的比特。 例如，如果给定的编码单元不具有邻居，则可以跳过标志，例如，不发信号通知。 在一个实施例中，语法元素，一个或多个标志可以发信号通知是否在编码单元中执行SAO滤波。 基于语法元素，可以跳过合并标志来保存位。 在一个实施例中，可以在切片级别发信号通知SAO语法。

Abstract: System and methods for improved playback of a video stream are presented. Video snippets are identified that include a number of consecutive frames for playback. Snippets may be evenly temporally spaced in the video stream or may be content adaptive. Then the first frame of a snippet may be selected as the first frame of a scene or other appropriate stopping point. Scene detection, object detection, motion detection, video metadata, or other information generated during encoding or decoding of the video stream may aid in appropriate snippet selection.

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.
