1. A video processor comprising:
- a real-time object (RTO) processor for processing object-based graphic image data describing an object-based graphic image to form pixel-based image data representing the object-based graphic image, said RTO processor incorporating memory means for intermediate storage of only said object-based graphic image data and forming pixel-based image data directly from said object-based graphic image data in real-time without using a pixel-based image data storage means, thereby permitting real-time colour mixing and generation of the pixel-based image data with a first video signal so as to form a second video signal;
a video input means for receiving said first video signal;
at least one colour mixing and generation device arranged to combine said first video signal with said pixel-based image data formed by said RTO processor to provide said second video signal; and
a video output means for outputting said second video signal.

Abstract
An inexpensive audio and video processing system (1) for combining animated object images with live video (28) with the addition of a combined audio capability (12) is disclosed. The system (1) includes a video processor system comprising a real-time object (RTO) processor (10) for rendering object-based graphic images, a video input means (30,27) for receiving a first video signal (28), at least one colour mixing and generation device (13) arranged to combine said first video signal (28) with image data (24) rendered from the RTO processor (10) to provide a second video signal and a video output means (38) for outputing same.

17. A video processor system comprising:
-
a host processor for compositing a list of graphic objects including graphic object-based data that together form an animated image; a real-time object processor for receiving said list, said real-time object processor including a storage area for intermediate storage of said graphic object-based data and forming therefrom object level data in pixel-based rasterized format in real-time without the use of a pixel-based memory, thereby permitting real-time colour mixing and generation of the object level data with a first video signal so as to form a second video signal; video input means for receiving a video input signal of a video image; colouring means for receiving said object level data in real-time as said object level data is formed by said real-time object processor, for assigning image colour thereto and for combining same with said video input signal to produce a combined signal of said animated image and said video image; and video output means for outputting said combined signal in a video format for rasterized display. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A video processor comprising:
-
a real-time object processor (RTO) for processing object-based graphic image data describing an object-based graphic image to form pixel-based image data, said RTO processor processing the object-based graphic image data by receiving object outlines of an image which include object fragments intended for rasterized display, by sorting the object fragments into a rasterization sequence corresponding to a scan line, by storing a rasterization sequence, by reading out in real-time a previously stored rasterization sequence, by calculating object edges, each having a priority level in each display line, and by assigning pixel data values within each display line based on the priority level; a video input for receiving a first video signal; at least one colour mixing and generation device arranged to combine the first video signal with the pixel-based image data formed by the RTO processor to provide a second video signal; and a video output means for outputting the second video signal.
