ABSTRACT:
A method and apparatus for clipping video information before scaling. In an embodiment of the invention, a transmitter obtains video information in the form of image data, as well as clipping information defining one or more display regions in which the image data is to be displayed. In accordance with the clipping information, the transmitter performs clipping operations on the image data, and transmits the clipped image data to a receiver. Prior to displaying the clipped image data, the receiver performs any needed scaling of the clipped image data to conform to the dimensions of the display regions. By performing clipping operations prior to transmission, and scaling operations subsequent to transmission, unnecessary image data is omitted and greater transmission efficiency is achieved.
