Disclosed is a control method of a display device including displaying a playback screen of video images, the playback screen of the video images showing one video image and a progress bar to visualize the progression of the video images, acquiring time information regarding respective bookmark images associated with the video images, the bookmark images respectively including the time information in the sequence of the video images and/or frame information regarding one video image corresponding to the time information, and displaying the bookmark images close to the progress bar at positions corresponding to the time information regarding the respective bookmark images. When a difference between first time information regarding a first bookmark image and second time information regarding a second bookmark image is a time threshold or less, the first and second bookmark images among the bookmark images are displayed as overlapping each other.

Aspects relate to transcoding a video at substantially the same time as the video is streamed so that upon completion of streaming, the transcoded video is available for immediate download. The transcoding can be performed on a client device or on a host device. Portions of the video can be tagged such that only the tagged portions are transcoded and made available for downloading. The tagged portions can be merged into a single file. Notification of the availability of the video can be broadcast. The broadcast can be controlled so as to be a public notification or a selective notification that is broadcast to a specified set or sets of individuals. Further, video chats can be recorded and compared so that a downloaded version of the video chat is an enhanced version of the information rendered on a user device.

An image display apparatus includes a data acquisition unit configured to acquire each of a plurality of pieces of LF image data in which a corresponding focus position being an in-focus position in a depth direction is changeable after image capturing, and a plurality of pieces of added data each of which is associated with a position in the depth direction, a group identification unit configured to identify a group to which at least one of the plurality of pieces of added data belongs, an image generation unit configured to generate, from a plurality of pieces of image data associated with one or more pieces of added data belonging to an identified group, each of a plurality of refocused images with a corresponding focus position set to a position associated with one or more pieces of added data belonging to the group, and a display control unit configured to display the plurality of refocused images on a display unit.

A method of classifying video data representing activity within a space to be monitored. A method comprises storing video data obtained from a camera configured to monitor the space. Sensor data indicative of a condition occurring within the space is obtained, and a plurality of programme elements are defined within the video data. Each programme element has an associated classification code, and each classification code is selected using the sensor data.

A video processing system includes: an object movement information acquiring means for detecting a moving object moving in a plurality of segment regions from video data obtained by shooting a monitoring target area, and acquiring movement segment region information as object movement information, the movement segment region information representing segment regions where the detected moving object has moved; an object movement information and video data storing means for storing the object movement information in association with the video data corresponding to the object movement information; a retrieval condition inputting means for inputting a sequence of the segment regions as a retrieval condition; and a video data retrieving means for retrieving the object movement information in accordance with the retrieval condition and outputting video data stored in association with the retrieved object movement information, the object movement information being stored by the object movement information and video data storing means.

An image processing apparatus comprises a generation unit configured to generate an image file of captured image data, the generation unit generating the image file with estimation results related to the image data added thereto as metadata, wherein the generation unit generates the metadata so that a first estimation result and a second estimation result are distinguishable from each other, the first estimation result being based on data that is included in the image file, the second estimation result being based on data that is not included in the image file.

An athletic parameter measurement device associated with a first user may include a display, a processor associated with the display, and an athletic parameter measurement sensor. During the athletic activity, the device may detect, using the sensor, athletic activity of the first user. Athletic data of the first user can be associated with activity information of a second user. A representation of a comparison of the first user's activity and the second user's activity information may be displayed.

An athletic parameter measurement device associated with a first user may include a display, a processor associated with the display, and an athletic parameter measurement sensor. During the athletic activity, the device may detect, using the sensor, athletic activity of the first user. A comparison of the first user's activity data with that of another user may be displayed, via an interface, to the fist user. The comparison between the two users may include synchronizing the athletic activity performances of the two users.

Systems and methods for interactive playback of a video conference are provided. A request is received for a playback of a video conference between a plurality of participants of a plurality of client devices that each generated one of a plurality of source video streams, where each source video stream was presented during a live stream of the video conference according to a particular layout in a user interface (UI) on a first client device of the plurality of client devices. Playback of the video conference is caused at a second client device, wherein causing playback of the video conference comprises transmitting, to a second client device, each source video stream of the plurality of source video streams for visual rendering according to the particular layout in a UI on the second client device; and capturing a first set of user interaction events associated with one or more time points during playback of the video conference, wherein each user interaction event of the first set is visually rendered at a corresponding time point during playback of the video conference.
