Abstract: A content streaming system and methodology for facilitating the management of content streaming. A content delivery service receives at least an original content stream and multiple input contents from an original content provider. Additionally, the content delivery service processes the received input content streams, buffers the original and supplemental input content streams, and switches between the available input content streams for seamless and fast broadcasting. The decision to switch between a second content and a third is determined by an indication that a third input content is available in the buffer.

Abstract: The invention relates to a keystone correction system and method. The system includes a projector for projecting an image on a projection surface and a platform to allow a user to vertically rotate the projector before horizontally rotating the projector. The projector corrects for keystone distortion responsive to the projector's vertical and horizontal position. The platform increases the keystone range of the projector. The keystone correction method includes moving a projector in a vertical direction and moving a projector in a horizontal direction after moving the projector in a vertical direction.
