Abstract
Abstract An editing system has a video store (8) for storing a video sequence and a text store (4) for storing a sequence of text associated with the video sequence. Displays (1) and (3) are provided for displaying the video and the text on the text display. The current text position is indicated by a cursor 10 or by another marker. The frames of the video sequence have time codes associated therewith. Corresponding time codes are associated with the text using the time codes and the rate n of reading words:- The current position in the text is controllable in dependence on the time code of the video frames; and the video frame currently displayed is controllable in dependence upon the current position in the text.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
119 words
An editing system comprising: means for simultaneously displaying a sequence of video frames and for displaying a sequence of text associated with the said sequence of video frames; a video store for storing the said sequence of frames to be displayed and time codes associated with the frames; a text store for storing the said associated sequence of text and time codes associated with the text; means for indicating on the display a current text position; and means for selectively a) controlling the display of the video frames in dependence upon the time code of the current text position and b) controlling the current text position in dependence upon the time code of the video frame currently being displayed.
Claim 2
Dependent Claim
21 words
A system according to claim 1, wherein the display means displays the video sequence and the text sequence side by side.
Claim 3
Dependent Claim
31 words
A system according to claim 2, wherein the displaying means comprises a single display screen and the video sequence and the text sequence are displayed in adjacent windows on the screen.
Claim 4
Dependent Claim
74 words
A system according to claim 1, 2 or 3 wherein the time code associated with the current text position is calculated from a first time code component TCx which denotes the start of a section of text and a second time code component W/ n where n is a preset rate of reading of words and W is the number of words of text from the start of the section to the current position.
Claim 5
Dependent Claim
41 words
A system according to claim 4, wherein the said time code component TCx denoting the start of a section of text is identical to the time code of the video frame corresponding to the start of the said section of text.
Claim 6
Dependent Claim
53 words
A system according to claim 4 or 5, wherein when the display of a video frame is controlled in dependence on the current text position, the controlling means selects from the video store the frame having the time code equal to or nearest to the time code associated with the current text position.
Claim 7
Dependent Claim
68 words
A system according to claim 4 or 5, wherein when the display of the current text position is controlled in dependence on the currently displayed video frame, the controlled means selects from the text store the section of text having a start time code TCx less than the time code VC of the current frame and calculates the current text position according to VC = TCx + W/n
Claim 8
Independent Claim
94 words
A system according to any one of claims 4 to 7 wherein a section of text associated with a corresponding section of the video sequence is divisible into: an initial active, sub-section containing a number of words Wx where Wx = (TCx+1 - TCx).n where n is the preset rate of reading or words, TCx is the time code denoting the start of the section, and TCx+1 is the time code denoting the start of the next section; and a succeeding inactive sub-section; and the said controlling means disregards text in the inactive subsection.
