Abstract
Abstract Method and apparatus for display of subtitles in connection with a motion picture are disclosed. A film strip includes coded signals adjacent a frame to be projected. These signals are detected by a detector and a microprocessor is controlled by the detector. The microprocessor has a sequence of subtitles recorded in a memory, and a display is activated by the microprocessor to exhibit a subtitle which corresponds to a detected coded signal. The microprocessor can contain subtitles for a plurality of languages, and multiple displays may be employed.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
101 words
Apparatus for display of subtitles during projection of a cinematographic film comprising a film strip having a plurality of frames adapted to cooperate with a projector for forming an image of said frames, said film strip having coded signals thereon, detector means for sensing the presence of said coded signals and for producing an output representative of a sensed coded signal, processor means containing a plurality of preselected subtitles for selecting a specific subtitle in response to an input signal from said detector means, and display means for displaying said selected subtitle in response to an input from said processor means.
Claim 2
Dependent Claim
101 words
Apparatus for display of subtitles during projection of a cinematographic film comprising a film strip having a plurality of frames adapted to cooperate with a projector for forming an image of said frames, said film strip having coded signals thereon, detector means for sensing the presence of said coded signals and for producing an output representative of a sensed coded signal, processor means containing a plurality of preselected subtitles for selecting a specific subtitle in response to an input signal from said detector means, and display means for displaying said selected subtitle in response to an input from said processor means.
Claim 3
Dependent Claim
31 words
Apparatus according to claim 1 wherein said film strip has a portion between an edge of said strip and edges of said frames and wherein said portion contains said coded signals.
Claim 4
Dependent Claim
20 words
Apparatus according to claim 2 wherein said portion has perforations therein and said coded signals are located between adjacent perforations.
Claim 5
Dependent Claim
27 words
Apparatus according to claim 1 wherein said strip includes coded signals adjacent only the first frame in a sequence of frames which correspond to a given subtitle.
Claim 6
Dependent Claim
25 words
Apparatus according to claim 1 wherein said coded signals comprise cancelling signals which, when sensed, caused said processor to terminate display of a particular subtitle.
Claim 7
Dependent Claim
16 words
Apparatus according to claim 4 wherein said cancelling signal comprises a signal for a successive subtitle.
Claim 8
Dependent Claim
22 words
Apparatus according to claim 1 wherein said processor maintains a time duration of a selected subtitle in accordance with a sensed signal.
Claim 9
Dependent Claim
11 words
Apparatus according to claim 1 further comprising a second display means.
Claim 10
Dependent Claim
19 words
Apparatus according to claim 8 wherein said display means and said second display means exhibit subtitles in different languages.
Claim 11
Dependent Claim
19 words
Apparatus according to claim 1 wherein said display means has a variable intensity which is controlled by said processor.
Claim 12
Dependent Claim
16 words
Apparatus according to claim 1 wherein said processor comprises memory means for receiving removable memory elements.
Claim 13
Dependent Claim
12 words
Apparatus according to claim 1 wherein said coded signals are optically detected.
Claim 14
Dependent Claim
12 words
Apparatus according to claim 1 wherein said coded signals are magnetically detected.
