摘要： A playback device and playback method are provided for reading out and playing content from a recording medium in which are recorded a video stream that is encoded video information, map information, and bitrate information of the video stream. The map information includes playback start time information, start position information, and size information. The playback method includes reading out the map information and the bitrate information, and determining the stipulated data size in accordance with the bitrate information. The playback method also includes acquiring the picture from the video stream based on the result of the determination, and the start position information and the size information included in the map information that has been read out. The method further includes decoding and playing the acquired picture, wherein the stipulated data size differs between 2K resolution of the video stream and 4K resolution of the video stream.

摘要： Provided is a process of dynamically creating a personalized workout video for a user. The process, including: obtaining a collection of workout video blocks; retrieving a user profile attribute from a user profile, the user profile attribute including a fitness goal or exercise constraint; selecting a first workout video block from the collection based on both the fitness goal or the exercise constraint and an intensity level or body-region grouping of the selected first workout video block; sending the first workout video block to a user device of the user; receiving after beginning to sending the first workout video block; selecting a second workout video block from the collection based on the feedback, the intensity of the second workout video block, and a body-region grouping of the second video block; and beginning to send the second workout video block, with one or more processors, to the user device.

摘要： In an approach for storing frames of a video, a computer divides a video into one or more frames. The computer identifies a frame type associated with an individual frame within the divided one or more frames, wherein the identified frame type includes one of the following: an I-frame, a B-frame, and a P-frame. The computer stores the individual frame within a corresponding storage location based on the associated identified frame type.

摘要： Some examples may generate one or more sets of compressed images from an image collection. Images from the image collection may be clustered into one or more sets of images based on one or more features in each image. A minimum spanning tree of images may be created from each of the one or more sets of images based on the one or more features in each image. Feature-based prediction may be performed using the feature-based minimum spanning tree. One or more sets of compressed images corresponding to the one or more sets of images may be generated.

摘要： 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.

In one or more aspects, a system is provided that includes a scene identification component configured to analyze a video comprising a plurality of sequential frames, including a plurality of intra-frames (I-frames) and a plurality of predictive frames (P-frames), and identify N groups of adjacent frames constituting N scenes of the video based in part on respective locations of the I-frames throughout the plurality of sequential frames, where N is an integer. The system further includes a video clip generation component configured to generate one or more video clips from one or more of the N scenes of the video, respectively, using portions of frames respectively associated with the one or more scenes of the N scenes of the video.
