Randomly accessible visual information recording medium and recording method, and reproducing device and reproducing method
Access point pictures designated as randomly accessible positions are I pictures or P pictures. Information indicating the decoding sequence (I1, P1, B1, B2, B3, B4, P2, . . . ) of pictures functioning as access points and attribute information (picture_type) indicating whether a picture functions as an access point or is necessary for decoding of the access point following a given access point are recorded on the video information recording medium. Random access is possible even if the GOP interval is lengthened.
SYSTEMS AND METHODS FOR GENERATING TIME LAPSE VIDEOS
Video information may define spherical video content having a duration. Spherical video content may define visual content viewable from a point of view as a function of progress through the spherical video content. Path information may define a path selection for the spherical video content. Path selection may include movement of a viewing window within the spherical video content. The viewing window may define extents of the visual content viewable from the point of view as the function of progress through the spherical video content. Time lapse parameter information may define at least two of a time portion of the duration, an image sampling rate, and a time lapse speed effect. A time lapse video may be generated based on the video information, the path information, and the time lapse parameter information.

SELECTIVE PLAYBACK OF AUDIO AT NORMAL SPEED DURING TRICK PLAY OPERATIONS
Systems and methods are described herein for selective playback of portions of audio at normal speed during a fast-forward operation. Upon receiving a command to perform a fast-forward operation, a current playback position is identified, as well as a plurality of portions of audio of the content item that will be subject to the fast-forward operation. A subset of the audio portions that will be subject to the fast-forward operation are selected. The fast-forward operation is initiated, and video of the content item is played back at the increased speed while the selected portions of audio of the content item are played back at normal speed.
Generation of correlated keyword and image data
A data processing apparatus includes a text acquisition mechanism acquiring texts to be used as keywords which will be subject to audio retrieval, the texts being related to contents corresponding to contents data including image data and audio data; a keyword acquisition mechanism acquiring the keywords from the texts; an audio retrieval mechanism retrieving utterance of the keywords from the audio data of the contents data and acquiring timing information representing the timing of the utterance of the keywords of which the utterance is retrieved; and a playback control mechanism generating, from image data around the time represented by the timing information, representation image data of a representation image which will be displayed together with the keywords and performing playback control of displaying the representation image corresponding to the representation image data together with the keywords which are uttered at the time represented by the timing information.

Low power framework for processing, compressing, and transmitting images at a mobile image capture device
The present disclosure provides an image capture, curation, and editing system that includes a resource-efficient mobile image capture device that continuously captures images. In particular, the present disclosure provides low power frameworks for processing, compressing, and transmitting images at a mobile image capture device. One example low power framework includes a scene analyzer that analyzes a scene depicted by a first image and determines whether to store the first image in a non-volatile memory or to discard the first image from a temporary image buffer without storing the first image in the non-volatile memory.
Imaging element, imaging apparatus, operation method of imaging element, and program
Provided is an imaging element including a reception interface that receives an imaging synchronization signal related to a timing of imaging and at least one output synchronization signal related to a timing of output of image data obtained by imaging from an outside of the imaging element, a memory that is incorporated in the imaging element and stores the image data obtained by imaging at a first frame rate in accordance with the imaging synchronization signal received by the reception interface, and an output circuit that is incorporated in the imaging element and outputs the image data stored in the memory at a second frame rate in accordance with the output synchronization signal received by the reception interface, in which the first frame rate is greater than or equal to the second frame rate.
Playlists for real-time or near real-time streaming
Methods, systems and machine readable storage medium for allowing playback of streaming media at playback rates of other than 1× are described. In one embodiment, a method can determine different sets of I-frames that are available before a display deadline, where each set can have a different cadence, and one of the sets can be selected for download and display to achieve playback at other than 1×. Byte range requests from a client device can be used to retrieve each of the I-frames. Other methods, system and media are also described.
