Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
242 words
A system for editing video material comprising: (a) first digital data handling means for receiving and
storing a sequence of image frames of relatively high
quality; (b) means for converting the sequence of image frames
into a corresponding sequence of image frames of
relatively low quality; (c) second digital data handling means for receiving
and storing the sequence of relatively low quality image
frames; (d) operator input means associated with the second
data handling means to enable manipulation of the
sequence of relatively low quality image frames for edit
decisions to be made; (e) communication means connected between the first and
second data handling means, for communicating to the
first data handling means edit decisions after
manipulation of the frames in the second data handling
means; and (f) means within the first data handling means for
producing an output sequence of relatively high quality
image frames in accordance with the edit decisions
communicated from the second data handling means,
characterised over this disclosure in that the edit
decisions are communicated to the first data handling
means substantially as such decisions are made; and in
that the system further comprises (g) means within the first data handling means for
processing a first edit decision, and for manipulating
the relatively high quality image frames accordingly,
whilst the operator manipulates the relatively low
quality frames in the second data handling means to make
a second edit decision for communication to the first
data handling means.
Claim 2
Dependent Claim
35 words
A system as claimed in claim 1, wherein the first
data handling means preferably includes means for
reducing the resolution of the images and/or compressing
the data, for supply to the second data handling means.
Claim 3
Dependent Claim
37 words
A system as claimed in claim 2, wherein (a) a plurality of different image resolutions are
provided from given source material; and (b) data in respect of different respective image
resolutions is compressed by different respective
amounts.
Claim 4
Dependent Claim
49 words
A system as claimed in claim 3, wherein, in the
first data handling means, parallel processors will work
on (a) high resolution, mildly compressed files for use
in the first data handling means; and (b) lower
resolution more highly compressed files for use in the
second data handling means.
Claim 5
Dependent Claim
82 words
A system as claimed in claim 2, 3 or 4, comprising
the steps of:- (a) Providing an image as a series of pixels, at a
first resolution; (b) Storing data relating to a second, lower resolution
version of the image in which the value of each
pixel is calculated as an average of a number of
associated pixels at the first resolution; and (c) Storing data from which the values of the
associated pixels can be calculated by a
simultaneous equation technique.
