A method ( 1600 ) and apparatus ( 220 ) for encoding a sequence of images for transmission over a communication network is disclosed. Initially ( 1602 ) an object-based first image is rendered from a computer graphics application ( 240 ). The rendered first image is then ( 1604 ) encoded ( 226 ) according to a predetermined encoding scheme and transmitted ( 1606 ) for remote display ( 116 ). A test ( 1608 ) is then performed to determine if any more images are to be rendered. If so, the next (further) image is rendered ( 1612 ) from the computer graphics application ( 240 ). Changes between the first image and the further image are then determined ( 1614 ) from a change indicating output ( 244,246 ) of the computer graphics application ( 240 ). The identified changes are then used ( 1616 ) to determine a manner in which the further image is to be encoded according to the predetermined format. The further image is then encoded ( 1618 ) based upon the changes, and transmitted ( 1620 ) for remote display. Further images are rendered and encoded using changes from the preceding image. |
