A device displays, in a first display region of a camera user interface, a first live view from a first camera. While displaying the first live view from the first camera, the device detects movement of a first user input (e.g., a first contact on a touch-sensitive surface). In accordance with a determination that the movement of the first user input meets first movement criteria, the device moves the first live view in the first display region in accordance with the movement of the first user input, displays a second live view from a second camera, and moves the second live view in the first display region in accordance with the movement of the first user input.

A method and system for displaying a composite video image has a sub-system associated with a video camera to monitor position, viewing direction or depth of focus of the camera when positioned at a setting to view a modification scene at a recording time. A video recording of an image of the modification scene is made and stored. At a viewing time subsequent to the recording time, a vantage position monitor sub-system associated with a viewer is used to monitor vantage position data related to the viewer's present vantage position. Modification image data is selected and accessed from memory, the accessed data depending on the monitored vantage position data. The image data corresponding to the foundation scene and the modification scene are combined as a composite image and displayed.

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 program elements are defined within the video data. Each program element has an associated classification code, and each classification code is selected using the sensor data.

For playing an interactive audiovisual movie, a movie episode data object which comprises a plurality of audio/video segments, separate audio tracks, and playback instructions is stored (51) in a data store of a computerized playback device. The playback device retrieves (52) the playback instructions and, in accordance with the playback instructions, retrieves (S31) and plays (532) audio/video segments, generates (535) interface elements for receiving from a user decision commands while playing the audio/video segments, and retrieves (S31) and plays (S32) further audio/video segments depending on the user decision commands. The playback device further retrieves (S33) one of the separate audio tracks and plays (S34) the separate audio track uninterruptedly while playing an end of a first audio/video segment and a start of a second audio/video segment which is played subsequently to the first audio/video segment. Thus, an audio track is played uninterruptedly across the boundary of two consecutive audio/video segments.

At least one video stream that is encoded video information, and a management information file indicating attributes relating to the entire recording medium, are recorded in a recording medium. The management information file includes attribute information indicating whether the dynamic range of luminance of an initial video stream, which is played first out of the at least one video stream when the recording medium is inserted into a playback device, is a first dynamic range, or a second dynamic range that is broader than the first dynamic range.

The present invention comprises an input part for inputting image data, a receiving part for receiving production information relating to production transmitted from another apparatus, a recording part for recording the production information received by the receiving part and image data input by the input part, a detection part for detecting a recording position on a recording medium at an editing point of image data recorded by the recording part, and a transmission part for transmitting information of the recording position detected by the detection part, whereby identification information for identifying image data and voice data is recorded in a recording medium or a recording device, this relieving a burden on a photographer and an editor and facilitating extraction of image data and voice data.

In some embodiments, methods and systems are provided for accessing a surgical dataset including surgical data collected during performance of a surgical procedure. The surgical data can include video data of the surgical procedure. Using the surgical data, a plurality of procedural states associated with the surgical procedure can be determined. For a procedural state of the plurality of procedural states, temporal information can be identified that identifies a part of the video data to be associated with the procedural state. For the procedural state of the plurality of procedural states, electronic data can be generated that characterizes the part of the video data and outputting the electronic data associated with the plurality of procedural states.

In order to provide a recording and reproducing device that allows a user to select and manage arbitrary play lists, a unit of management for managing all registered play list information and an upper management hierarchical level are added. The unit of management is adapted to be handled on the same level with unified information that indicates a reproduction range of all AV data. User-defined unified information is adapted to be handled on the added management hierarchical level. The user-defined unified information is formed to allow arbitrary reproduction ranges contained on a lower hierarchical level to be registered.

An image and audio reproduction device obtains an image captured by an image capturing device and a plurality of acoustic signals whose arrival directions are respectively a plurality of locations in an image capturing scope of the image capturing device, and sets, as one group, arrival directions of acoustic signals with a high degree of similarity of amounts of characteristics on the basis of a degree of similarity of the amounts of characteristics between the acoustic signals that are from the arrival directions adjacent to each other. The image and audio reproduction device adds information to the image captured by the image capturing device so as to reproduce the image, the information representing a position of the group in an image capturing scope of the image capturing device.

The present invention comprises an input part for inputting image data, a receiving part for receiving production information relating to production transmitted from another apparatus, a recording part for recording the production information received by the receiving part and image data input by the input part, a detection part for detecting a recording position on a recording medium at an editing point of image data recorded by the recording part, and a transmission part for transmitting information of the recording position detected by the detection part, whereby identification information for identifying image data and voice data is recorded in a recording medium or a recording device, this relieving a burden on a photographer and an editor and facilitating extraction of image data and voice data.
