Abstract: Methods of displaying video data are disclosed. The methods generate a plurality of queries for determining from which of a plurality of video data sources video data is to be displayed and store each of the queries. One of the queries is selected for display and the selected query is matched with metadata from one or more of the plurality of video data sources. The video data from the video data sources that match the query is displayed.

Abstract: A method of providing a print representation of a document which, when printed, has at least one region the appearance of which is dependent on viewing conditions. The method comprises generating a representation of the document and then modifying the appearance of the at least one region to thereby simulate the appearance of the document when printed. This is achieved by animating the representation of the at least one region or at least partially combining the at least one region with an image.

Abstract: Methods and apparatus for variable document printing are disclosed in which a graphical user interface is configured to allow user manipulation of layout rules associated with content containers within a template for variable document generation. One method involves creating a layout for a variable data document based upon a template. The method firstly sets at least one container in the template to form the layout, and then establishes at least one constraint associated with each selected one of at least one feature of the container, the establishing including, for each feature, detecting a user instigated selection of the corresponding feature. The layout is then modified to thereby generate the document by placing content into the containers, wherein at least one dimension of the least one container and/or a position of the at least one container in the layout are varied based on a property of the placed content on a condition that each constraint in the layout is satisfied.

Abstract: Methods and apparatus for proofing (644) a variable document intended for printing are disclosed in which a GUI (2000) is configured to allow user manipulation of layout rules associated with content containers within a template for variable document generation. Selective proofing (2100) involves proofing a plurality of variable data documents each formed from a common layout in which variable data content is placed into containers having locations and sizes within the layout and defined by layout rules. Measures of variation (2103, 2106) and measures of deviation (2109, 2110) are calculated. The measures of deviation are processed (2112) to give a deviation value. Once completed for each document, the deviation values of the documents are compared (2114) to identify at least one group of the documents for presentation for further assessment. Live proofing includes creating a layout (2002) for a variable data document based upon a template established in the GUI.
