Systems and methods for transmitting video frames are described. Specifically, frame rate modification techniques such as blending and/or packing processes are used to translate high frame-rate signals into low-frame rate signals, which are transmitted over limited bandwidth transmission media to a video signal receiver. Information pertaining to the blending and/or packing processes is transferred to the video signal receiver in the form of a map that is used to reconstruct the high frame-rate signals from the low-frame rate signals. The high frame-rate signals may be used by certain types of newer equipment designed to use such signals. However, legacy equipment that cannot use the high frame-rate signals may opt to use certain embodiments described herein that are designed to be backward-compatible. When backward-compatible, the video signal receiver generates suitable low frame-rate signals as well as the high frame-rate signals, thereby accommodating both legacy as well as newer equipment.
