An electronic device is disclosed. In addition, various embodiments identified through the specification are possible. The electronic device includes a display, a processor, and a memory storing instructions that, when executed by the processor, cause the processor to display, when a video supporting a plurality of orientation regions is played, a first screen corresponding to a first orientation region among the plurality of orientation regions, display a timeline representing a playback time of the video, display thumbnails of screens corresponding to the plurality of orientation regions at the first time point in response to a first user input pointing a first time point in the timeline, and receive a second user input scrolling the thumbnails.

A method, apparatus and computer program product describing groups of overlays, such as semantically correlated overlays, to background media content. In the context of a method, a group of overlays to background media content is defined by metadata (60). The overlays include semantically correlated overlays having alternative overlays representing content with different levels of detail or overlays providing different choices of content. The method also includes receiving client selection of a respective overlay from a group of overlays (62). In response to the client selection, the method causes the respective overlay to be provided. The respective overlay is received (64) for presentation concurrent with background media content (68).

An apparatus for transmitting a video comprises an inter-view redundancy remover configured to remove redundant information of pictures for viewing positions, where redundant pixel information between the pictures in adjacent viewing positions is removed, a packing unit configured to pack the pictures and generate packing information, and an encoder configured to encode the pictures. The apparatus is further configured to perform multi-view packing the pictures into a packed picture, where each view for the picture includes different types of a texture and a depth map, and a residual of texture and a depth map are generated for a subsidiary view based on redundancy between each view. The apparatus is further configured to generate signaling information for the inter-view redundancy remover, the packing unit, or the multi-view packing.

A method is provided for displaying a multi-depth image in which one or more images are inserted into a main image in a tree structure and one or more objects are mapped to at least some of the one or more images. The method comprises generating at least one content tree from the tree structure of the multi-depth image; and configuring a display area corresponding to each of the at least one content tree. The display area includes a first area for displaying an image corresponding to each node of the content tree, and a second area for displaying an object corresponding to each node of the content tree or a playback user interface (UI) of the object. The first area and the second area respectively display the image and the object mapped thereto or the playback UI in synchronization with each other.

A subtitle information display method includes: when an editing operation of a user for initial subtitle information of video information is detected, determining a video display region and an edited subtitle display region in an application display page; if the subtitle display region is not a subregion in the video display region, determining a first extension length and a first extension direction for each edge length of the video display region based on region information of the video display region and region information of the subtitle display region; extend the video display region within a region range corresponding to the application display page, based on the first extension length and the first extension direction, so that the extended video display region includes the subtitle display region; and displaying edited subtitle information in the subtitle display region.
