Embodiments of the invention provide a method and a system for realizing a 4D digital film based on a DCI standard. The method comprises the following steps: making an environment instruction bag corresponding to a 3D commercial digital film using files according with the DCI standard; placing the environment instruction bag in an environment server; receiving an operation instruction sent from a digital film server by the environment server when the 3D commercial digital film starts to be shown; and executing the environment instruction bag according to the operation instruction to make execution of environment motion maintain synchronization with the play of the 3D commercial digital film. Embodiments in the invention utilize files satisfying the DCI standard to make the environment instruction bag directing at the 3D commercial digital film, wherein the environment instruction bag and the 3D commercial digital film are executed separately while maintaining synchronization between each other, so that a 4D dynamic effect can be reached with low realization cost when a common digital film is played in a digital cinema.
Description
Technical field
The present invention relates to the video playback technical field, especially relate to a kind of 4D digital movie implementation method and system based on the DCI standard.
Background technology
The 4D film is on the basis of 3D three-dimensional film, to add environment special efficacy analog simulation and develop and the novel video display product that comes.Also be referred to as four-dimensional film: space-time is formed in promptly three-dimensional three-dimensional film and surrounding environment simulation.Spectators except the shock of traditional 3D vision, along the variation of movie and television contents, can experience storm, thunder and lightning in real time, rain, bump, spray water smoke, clap the incident corresponding with exploded view that leg etc. is taken place at one's side when seeing three-dimensional film.Compare with traditional 3D three-dimensional film, spectators can also experience comprehensive impressions such as sense of touch, sense of smell except vision, the sense of hearing when watching the 4D film.
But because the 4D film making is the system of a sealing, only grasp in several companies hand at present, it is high to make finished product, all is the short-movie of length of a film about 20 minutes generally.Therefore the film source of 4D film is very rare, and formal 4D commercial digital film does not have especially.
Existing 4D film producing process sketch map can be referring to shown in Figure 1; Generally be to take or be input to the 3D film of having taken in the 4D synthesis system through two-shipper; The environment action that also actions editor is editted simultaneously inputs in the 4D synthesis system, through the 4D film bag of the synthetic privately owned form of 4D synthesis system.The projection process of the 4D film of this privately owned form is as shown in Figure 2, from privately owned 4D movie services device, reads this 4D film bag earlier, from this 4D film bag, solves audio signal, delivers to the reduction of accomplishing sound in the sound system; And from this 4D film bag, solve vision signal, and deliver in the projector, accomplish the projection of 3D film through the 3D system; From this 4D film bag, solve the environment action directive simultaneously, deliver in seat and the environmental control, accomplish control seat and environment.
Making and projection description through above-mentioned existing 4D film can find out that existing 4D film also exists following defective:
Because the closure of system; Make others can't learn the format standard of 4D film bag; Its 4D film bag must not meet the DCI standard of commercial digital film yet; Can't be used on the digital projection system of commercial theater,, must install a cover 4D projection system additional if existing commercial digital movie theatre wants to play this 4D film bag.In addition; The 4D movie services device that is used to show the 4D film also can only read the special-purpose film bag of 4D film; And the incompatible commercial digital film bag that meets the DCI standard; Same, if the 4D movie theatre wants to play the commercial digital film, also must install the digital film projector system that a cover meets the DCI standard additional.
