A multimedia file and methods of generating, distributing and using the multimedia file are described. Multimedia files in accordance with embodiments of the present invention can contain multiple video tracks, multiple audio tracks, multiple subtitle tracks, data that can be used to generate a menu interface to access the contents of the file and ‘meta data’ concerning the contents of the file. Multimedia files in accordance with several embodiments of the present invention also include references to video tracks, audio tracks, subtitle tracks and ‘meta data’ external to the file. One embodiment of a multimedia file in accordance with the present invention includes a series of encoded video frames and encoded menu information.

An athletic parameter measurement device worn by an athlete during an athletic activity session includes a housing which attaches to the athlete, a display, a processor associated with the display, and an athletic parameter measurement sensor. During the athletic activity, the device detects, using the sensor, a vertical jump height of the athlete, and displays, during the performance of the athletic activity session, a representation of the vertical jump height on the display.

A position estimation system includes: a reference image database configured to store a reference image and information indicating a position in a state in which they are associated with each other; an acquisition unit configured to acquire an image for estimation which is a position estimation target; an estimation unit which performs comparison of the reference image with the image for estimation, estimate the position related to the image for estimation from the information indicating the position associated with the reference image, and calculate a reliability of the estimated position; and an update unit configured to update the reference image using the image for estimation on the basis of the reliability.

A screen recording method includes obtaining operation data of an electronic device and response data generated by the electronic device based on the operation data; obtaining a virtual device image matching the electronic device; and associating the operation data and the response data with the virtual device image according to a pre-determined processing strategy to generate a first video.

A video recording method and device, an electronic device and a storage medium are provided. The method includes: acquiring speed varying information of a speed-varied video, where the speed varying information is used to represent a playing speed change of the speed-varied video; performing reverse speed-varying processing on the speed-varied video according to the speed varying information to obtain an original speed video; displaying the original speed video, and synchronously performing video shooting to generate an original speed target video; and performing speed varying processing on the original speed target video according to the speed varying information to obtain a target speed-varied video.

An image processing apparatus comprises: a detection unit that detects a subject from an image; an inference unit that performs inference processing using an inference model on the detected subject; and a generation unit that generates an image file by combining image data of the image, information of the subject, an inference result of the inference processing, and information of the inference model. The generation unit records the inference model in a private area of the image file.

A method is disclosed for displaying a sequence of video items on an electronic device. During playback of a current video item, a dismissal input such as a swipe or tap/click is received via a user input mechanism, indicating that display of the current video item is to be ceased and that display of the next video item in the sequence is to be commenced. In response to the dismissal input, summary information is displayed on the display screen, providing non-video communication of an informational payload of the current video item. A timer is started at the commencement of display of the summary information, at the expiry of which display of the next video item is to be commenced. In response to a resumption input such as a touchscreen tap or cursor click on the summary information before expiry of the timer, playback of the current video item is resumed via the display screen.

In aspects of personal content managed during extended display screen recording, a screen recording system includes a wireless device that provides digital image content for display on an extended display device, and a screen recording session on the wireless device captures the digital image content and audio data. The wireless device implements a content control module that can determine the screen recording session would capture personal content associated with a user of the wireless device. The content control module can initiate a private screen review mode in which the personal content is displayable on a display screen of the wireless device and is prevented from visual display on the extended display device. The content control module can also generate a shareable screen recording that includes the audio data and the digital image content displayed on the extended display device, without including the personal content.
