ABSTRACT:
A television system 106 and display method for receiving and displaying television broadcasts having various formats. The television system resizes (106) the various received image formats for display on a common display device. Images are resized horizontally by altering the rate at which data is sampled by the television (106). Images are resized vertically by using vertical scaling algorithms which alter the number of lines in an image. Format detection may be done automatically by decoding information contained in the vertical interval of the television broadcast signal, or by counting the number of lines in each frame. The input format may be indicated by a viewer.
