Methods, systems, devices, and software are described for providing supplemental content for presentation on a mobile device that identifies a video and a portion within the video. In one embodiment, a system includes a mobile device with an integrated video camera that tracks a display playing a movie. The mobile device automatically identifies the current scene in the movie and then accesses supplemental non-video content related to the identified scene. The accessed supplemental non-video content (e.g., audio, tactile, olfactory data) is then presented to the user at the same time the movie is played.

The present invention relates to a method and system for providing a 4D content production service and a content production apparatus therefor. The system for providing a 4D content production service includes: a terminal device configured to transmit content source including at least one of a picture, text and video, synopsis information and video time information and video time information, to receive content and special effect codes, to select a special effect code corresponding to each play interval of the content and to transmit special effect selection information indicating selected special effect codes; and a content production apparatus configured to produce content using the content source on the basis of the synopsis information and video time information received from the terminal device, to transmit the produced content and special effect codes to the terminal device, to receive the special effect selection information from the terminal device and to generate 4D content using the special effect selection information. According to the present invention, a business proprietor can promote business expansion and improve the image of business and a user can produce 4D content by directly participating in content selection and production.

Provided is a method and system for creating and using a video tag. A method configured as a computer may include creating tagging information by connecting information about at least one partial playback section in an entire playback section of a video to a tag designated by a user; and storing the tagging information in association with the at least one partial playback section instead of storing the at least one partial playback section.

A method and system may provide for interactive song generation. In one aspect, a computer system may present options for selecting a background track. The computer system may generate suggested lyrics based on parameters entered by the user. User interface elements allow the computer system to receive input of lyrics. As the user inputs lyrics, the computer system may update its suggestions of lyrics based on the previously input lyrics. In addition, the computer system may generate proposed melodies to go with the lyrics and the background track. The user may select from among the melodies created for each portion of lyrics. The computer system may optionally generate a computer-synthesized vocal(s) or capture a vocal track of a human voice singing the song. The background track, lyrics, melodies, and vocals may be combined to produce a complete song without requiring musical training or experience by the user.

A system and method for transferring annotations associated with a media file. An annotation associated with a media file is indexed to a first instance of that media file. By comparing features of the two instances, a mapping is created between the first instance of the media file and a second instance of the media file. The annotation can be indexed to the second instance using the mapping between the first and second instances. The annotation can be processed (displayed, stored, or modified) based on the index to the second instance.
