Abstract: 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.

Abstract: A method of optical heart rate sensing includes receiving a motion frequency from a motion sensor and receiving an optical signal from an optical sensor. The motion frequency is then filtered from the optical signal, and an estimated heart rate frequency is determined based on the filtered optical signal. A heart rate is reported that is based on the motion frequency, but not based on the estimated heart rate frequency, when a local neighbor magnitude ratio of the estimated heart rate frequency is below a confidence threshold.

The sub-pod includes a valve assembly, wherein the valve assembly includes a solenoid, an electronics interface, and a directional control valve. The sub-pod further includes a modular valve pack and a controller, wherein the modular valve pack comprises a manifold, and wherein the manifold is operable to support the valve assembly within the manifold.

Abstract: A hand tool comprising a body with a first end and a second end, a striking portion disposed at the first end of the body, a hand grip disposed about a portion of the body, the hand grip defining a first elongated recess, and a cutting device removable received in the first elongated recess of the hand grip.

Abstract: A wrench including a handle having a first yoke at a first end and a first plurality of tool heads coupled to the first yoke at a first pivot axis, at least a first tool head of the first plurality of tool heads having a drive cavity. Each tool head of the first plurality of tool heads is pivotable about the first pivot axis independently of the other tool heads of the first plurality of tool heads.

Abstract: A sequence of video images can be represented using multiple related timelines by generating a first timeline identifying a decode order associated with a sequence of video images and a second timeline identifying a display order associated with the sequence of video images, wherein the sequence of video images is comprised of one or more samples. The first and second timelines can be correlated based on an offset, which represents a time period by which decoding precedes display. The sequence of video images can then be played in accordance with the correlated first and second timelines. Additionally, the decode order in the first timeline can differ from the display order in the second timeline. A revised offset between the first and second timelines can be determined after the sequence of video images has been edited and the first and second timelines can be correlated based on the revised offset.

Abstract: A method and system for accessing media metadata from metadata stored in different native formats is disclosed. A repository contains a plurality of containers for storing media metadata, wherein a first container in the repository stores metadata in the first native format, and a second container in the repository stores metadata in the second native format. A set of routines is used to access all media metadata stored in the repository without regard to the native format in which the media metadata is stored. Each routine in the set of routines identifies a metadata item stored in a container through information passed in a set of parameters. The set of parameters comprises a reference to the repository, an identifier of a container in the repository, an identifier of a structure for a key for the identified native format, and a key.

Abstract: The operation of a video playback application supporting display of an encoded video may be validated using a special-purpose video decoder. The decoder compares pre-determined indications of dependency frames for frames of the video with dependency frames that are identified based on an order in which the frames are provided to the decoder. Based on the comparison, the decoder verifies that the frames may be decoded with correct dependencies. In one implementation, a frame of a video is accessed. A first description and a second description identifying frames of the video upon which decoding of the accessed frame depends are accessed. The first description is compared to the second description, and whether the first and second descriptions identify a common set of frames is determined based on the identifying.

Abstract: Playing a media file can include receiving input from a user identifying a playback location associated with a media file; downloading media content corresponding to the identified playback location from the media file; displaying a status bar to the user on a display device; and presenting a download indicator associated with the status bar showing an amount of downloaded media content, wherein the downloaded media content comprises a contiguous portion of the media file that includes the identified playback location. Further, playing the media file can include receiving additional input from a user identifying a new playback location associated with a media file; downloading media content corresponding to the new playback location; and presenting a new download indicator associated with the status bar showing an amount of downloaded media content, wherein the downloaded media content comprises a contiguous portion of the media file that includes the new playback location.

Abstract: Playing a media file can include receiving input from a user identifying a playback location associated with a media file; downloading media content corresponding to the identified playback location from the media file; displaying a status bar to the user on a display device; and presenting a download indicator associated with the status bar showing an amount of downloaded media content, wherein the downloaded media content comprises a contiguous portion of the media file that includes the identified playback location.

Abstract: At least a portion of a media file can be downloaded by accessing one or more items of media data associated with a media file stored on a remote server, wherein the media data includes at least one sample table; receiving input from a user identifying a playback location associated with the media file; determining a plurality of data items required to play at least a portion of the media file from the identified playback location based on the at least one sample table; and transmitting one or more byte-range requests to the remote server using the hypertext transfer protocol to retrieve the plurality of data items. Further, the media file can be progressively downloaded from the identified playback location until the end of the media file is reached, playback of the media file is terminated, or input is received from the user identifying a new playback location.
