Generation of video
First Claim
1. An apparatus for generating video data derived from the execution of a computer program, the apparatus having first and second modes of operation;
- wherein, in the first mode of operation, the apparatus is operable to execute a computer program comprising a plurality of components, wherein the execution of each component is conducted in a sequence of execution frames, the apparatus being further operable in said first mode of operation to record video data comprising a sequence of video data frames corresponding to the sequence of execution frames; and
wherein, in the second mode of operation, the apparatus is operable to process video data which have been recorded during the previous execution of a computer program, in order to allow a user to obtain a visualization of the execution of that computer program, and wherein, in the second mode of operation, the apparatus is further operable to allow a user, at any frame of said sequence of video data frames, to change the mode of operation of the apparatus to the first mode of operation and to obtain, from said video data, the state of the corresponding execution frame of the computer program, the apparatus further comprising;
means operable to allow a user to modify said video data by a step selected from the group consisting of at least one of adding an item to the frame, deleting an item from the frame, and changing the state of one or more items comprised in the frame, such that, in the first mode of execution, the apparatus is then operable to execute the computer program starting from the modified frame using the modified data, and to record video data resulting from the execution of the computer program.

Abstract
An apparatus and a method are provided for generating video data derived from the execution of a computer program. In a first mode, the apparatus is operable to (a) execute a computer program comprising one or more components executed in a sequence of execution frames, each execution frame having a given state; and (b) record video data comprising a sequence of video data frames corresponding to the sequence of execution frames. In a second mode, the apparatus is operable to (c) process video data which have been recorded during the previous execution of the program, to allow a visualization of the execution of that program; and (d) allow a user, at any frame of the sequence of video data frames, to change the mode to the first mode and to obtain from the video data the state of the corresponding execution frame of the program.

14. A method for generating video data derived from the execution of a computer program, the method comprising:
-
i) executing one or more components of a computer program in an execution environment operable such that the execution of each component is conducted in a sequence of execution frames; ii) during said execution, recording video data corresponding to said sequence of execution frames, wherein said video data are sufficient to allow the state of any frame of execution to be recreated; iii) obtaining a desired sequence of re-execution frames from said video data; iv) executing the sequence of re-execution frames obtained in step iii) in said execution environment; v) pausing the execution of said sequence of re-execution frames at a given frame to obtain a candidate frame; vi) modifying the state of said candidate frame by a step selected from the group consisting of at least one of adding an item to the frame, deleting an item from the frame, and changing the state of one or more items comprised in the frame, to obtain a modified sequence of re-execution frames; and vii) executing the computer program using data of the modified sequence of re-execution frames and recording video data resulting from the execution of the computer program. - View Dependent Claims (15, 16, 17)

18. A method for generating video data derived from the execution of a computer program, the method comprising:
-
i) obtaining a desired sequence of re-execution frames from video data recorded during the previous execution of a computer program comprising one or more components; ii) executing said sequence of re-execution frames in an execution environment operable such that the execution of each component is conducted in a sequence of execution frames; iii) pausing the execution of said sequence of re-execution frames at a given frame to obtain a candidate frame having a given state; iv) modifying the state of said candidate frame by a step selected from the group consisting of at least one of adding an item to the frame, deleting an item from the frame, and changing the state of one or more items comprised in the frame, to obtain a modified sequence of re-execution frames; and v) executing the computer program using data of the modified sequence of re-execution frames and recording video data resulting from the execution of the computer program. - View Dependent Claims (19, 20, 21)

22. An apparatus for generating video data derived from the execution of a computer program, the apparatus comprising:
-
i) an execution environment generation module configured to generate an execution environment operable to execute one or more components of a computer program such that the execution of each component is conducted in a sequence of execution frames; ii) a recording device operable to record video data corresponding to a sequence of execution frames being executed by said execution environment, wherein said video data are sufficient to allow the state of any frame of execution to be recreated, and wherein said apparatus is operable to obtain a desired sequence of re-execution frames from said video data, said sequence of re-execution frames being for execution in said execution environment; and iii) a frame state modifier operable, following an interruption of the execution of a sequence of re-execution frames by said execution environment, to allow modification of the state of a candidate re-execution frame by a step selected from the group consisting of at least one of adding an item to the frame, deleting an item from the frame, and changing the state of one or more items comprised in the frame, to obtain a modified sequence of re-execution frames for execution by said execution environment. - View Dependent Claims (23, 24)
