摘要： This is directed to systems, methods and computer-readable media for media files having timed and untimed location metadata. For example, a media file can include timed location metadata stored in a metadata track of the media file, such that individual timed packets of location information are each associated with different portions of the recorded media. In some embodiments, the location metadata can include information describing the direction the device is facing and/or elevation/tilt of the device relative a horizontal plane (e.g. a plane perpendicular to a line between the device position and the center of the earth) and/or a motion of the device.

摘要： A method and apparatus for performing motion estimation in a digital video system is disclosed. Specifically, the present invention discloses a system that quickly calculates estimated motion vectors in a very efficient manner. In one embodiment, a first multiplicand is determined by multiplying a first display time difference between a first video picture and a second video picture by a power of two scale value. This step scales up a numerator for a ratio. Next, the system determines a scaled ratio by dividing that scaled numerator by a second first display time difference between said second video picture and a third video picture. The scaled ratio is then stored calculating motion vector estimations. By storing the scaled ratio, all the estimated motion vectors can be calculated quickly with good precision since the scaled ratio saves significant bits and reducing the scale is performed by simple shifts.

摘要： A method and apparatus for variable accuracy inter-picture timing specification for digital video encoding is disclosed. Specifically, the present invention discloses a system that allows the relative timing of nearby video pictures to be encoded in a very efficient manner. In one embodiment, the display time difference between a current video picture and a nearby video picture is determined. The display time difference is then encoded into a digital representation of the video picture. In a preferred embodiment, the nearby video picture is the most recently transmitted stored picture. For coding efficiency, the display time difference may be encoded using a variable length coding system or arithmetic coding. In an alternate embodiment, the display time difference is encoded as a power of two to reduce the number of bits transmitted.

摘要： Disclosed herein is a technique for delimiting the alpha channel at the NAL layer in codecs like H.264 to facilitate the optional nature of the alpha channel. In coded video sequences that include alpha, there is one alpha picture for every primary coded (e.g., luma-chroma) picture, and the coded alpha picture is contained in the same access unit as its corresponding primary coded picture. The alpha coded slice NAL units of each access unit are sent after the NAL units of the primary coded picture and redundant coded pictures, if any. The presence or absence of the alpha NAL units does not affect the decoding of the remaining NAL units in any way.
摘要翻译：这里公开了一种用于在编码解码器（例如H.264）中限定NAL层处的阿尔法通道的技术，以便于α通道的可选性质。在包括α的编码视频序列中，对于每个主编码（例如，亮度 - 色度）图像存在一个α图像，并且编码的α图像被包含在与其对应的主编码图像相同的存取单元中。每个访问单元的α编码片NAL单元在主编码图像的NAL单元和冗余编码图像之后发送（如果有的话）。 αNAL单元的存在或不存在不影响以任何方式解码剩余的NAL单元。

摘要： A perimeter around a detected object in a frame of image data can be generated in a first coordinate system. The perimeter can be converted from the first coordinate system into a second coordinate system having the same aspect ratio as the first coordinate system. A first metadata entry can include dimensions of image data in the second coordinate system. A second metadata entry can provide a location and dimensions of the converted perimeter in the second coordinate space. Additional metadata can indicate matching objects between frames, position of an object relative to other objects in a frame, a probability that an object is correctly detected, and a total number of objects detected across multiple frames of image data.
