Abstract
A storage medium, such as a digital versatile disc (DVD), that includes both a media and a data portion. The media portion comprises, for example, one or more scenes movie, a television program or the like. In certain embodiments, the media portion s a full-length movie. The data portion includes reference information, such as data able by a compositing device to selectively insert a real-time image into a video scene on the media portion. For example, the data files may contain a plurality of trigger that provides for the display, at appropriate times, of a real-time composite image of the prerecorded video scene.
Claims20
A storage medium for use in interactive video compositing, the storage medium comprising:
- a first portion including media data usable to produce at least one video image having multiple frames;
- and
- a second portion including reference data associated with the media data and further comprising first video reference data and second video reference data, wherein the first video reference data identifies a first frame of the at least one video image to be combined with a second video image to form a composite video image to be communicated to a display, and wherein the second video reference data identifies a second frame of the at least one video image to be communicated to the display.
A method for video compositing, the method comprising:
- receiving from a prerecorded medium a first video signal having multiple frames;
- receiving a second video signal;
- creating a composite signal by mixing the first video signal and the second video signal;
- and
- selectively switching between outputting the first video signal and outputting the composite signal, wherein said selective switching is performed automatically and is based at least in part on reference data, stored on the prerecorded medium, that corresponds to frames of the first video signal.
A system for real-time video compositing, the system comprising:
- a reader configured to obtain from a storage medium a first video signal and at least one data file associated with the first video signal, the at least one data file having at least first reference data and second reference data;
- a video input configured to receive a second video signal;
- a mixing module coupled to the reader and to the video input, wherein the mixing module is configured to output a composite signal comprising portions of the first video signal and portions of the second video signal;
- and
- a switching module that selects between outputting the composite signal and outputting the first video signal, wherein the switching module outputs the composite signal at a time identified by the first reference data and outputs the first video signal at a time identified by the second reference data.
An electronic system for performing video compositing, the electronic system comprising:
- means for receiving from a single storage medium a first video signal and at least one data file associated with the first video signal, the at least one data file including first reference data and second reference data;
- means for receiving a second real-time video signal;
- means outputting a composite signal comprising portions of the first video signal and portions of the second real-time video signal;
- and
- means for selectively switching between outputting the composite signal and outputting the first video signal, wherein said means for selectively switching automatically outputs the composite signal at a time identified by the first reference data and automatically outputs the first video signal at a time identified by the second reference data.
