Abstract
Methods are described for displaying video including variable frame rates. A method for displaying images includes receiving digital video data including video image data in a display system capable of displaying images at multiple frame rates; storing the digital video data in at least one frame buffer coupled to the display system; receiving in the digital video data ancillary data comprising at least configuration parameters indicating a current frame rate and a future frame rate; storing the parameters representative of a current frame rate in a first timing control buffer coupled to the display system; storing the parameters representative of a future frame rate in a second timing control buffer; displaying images from data in the frame buffer at the current frame rate; and upon detection of a swap condition, instantly displaying images from data in the frame buffer at the future frame rate. Additional methods and apparatus are described.
