Abstract
Abstract A digital video special effect system for merging or replacing a first video image with a second video image. A first special effect means receives digital video information relating to a first picture sequence and transitions can be implemented in order to change the format of the image. Second special effect means provides the same facility for a second video image whereby the first and second images can be combined. A common memory stores commands to cause the first and second special effect means to cooperate on a common time-line whereby the durations of the picture sequences are automatically adjusted in order to provide a smooth combination of video images.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
166 words
A digital special effect system, including: (a) a first special effect means for receiving digital video information relating to a first picture sequence and for implementing transitions so as to provide video information representing a transitioned first picture sequence; (b) a second special effedt means for receiving digital video information relating to a second picture sequence, for receiving the video information representing the transitioned first picture sequence, and for implementing transitions for merging or replacing the transitioned first picture sequence with a transitioned second picture sequence; and (c) a common memory means for storing data relating to the video information representing the transitioned first picture sequence, data relating to the video information representing the transitioned second picture sequence, and commands for causing the first special effect means and the second special effect means to cooperate on a common time-line, wherein the system automatically adjusts durations of said picture sequences, in accordance with input data relating to said merging or replacing, to produce a required total effect.
Claim 2
Dependent Claim
166 words
A digital special effect system, including: (a) a first special effect means for receiving digital video information relating to a first picture sequence and for implementing transitions so as to provide video information representing a transitioned first picture sequence; (b) a second special effedt means for receiving digital video information relating to a second picture sequence, for receiving the video information representing the transitioned first picture sequence, and for implementing transitions for merging or replacing the transitioned first picture sequence with a transitioned second picture sequence; and (c) a common memory means for storing data relating to the video information representing the transitioned first picture sequence, data relating to the video information representing the transitioned second picture sequence, and commands for causing the first special effect means and the second special effect means to cooperate on a common time-line, wherein the system automatically adjusts durations of said picture sequences, in accordance with input data relating to said merging or replacing, to produce a required total effect.
Claim 3
Dependent Claim
32 words
The system of claim 1, wherein the first special effect means is a size and position special effect means and wherein the second special effect means is a mix/wipe special effect means.
