Abstract
A video formatter reformats progressive video using a film-based video film rate and a display refresh rate to determine a frame OFF period for a progressive video sequence. The video formatter inserts at least one black frame into the progressive video sequence to approximate the frame OFF period. Typically, the film rate is 24 frames per second (industry standard) and, thus, the display refresh rate can be a multiple of the frame rate (e.g., 96 Hz, 120 Hz, 240 Hz, etc.). Progressive video replicates a single frame of a film several times (“a progressive video sequence”) depending on a display's refresh rate. The black frame(s) is/are substituted at the end of this sequence instead of displaying the same image throughout for a single film frame.
Claims17
A system, comprising:
- a video formatter that reformats progressive video using a film-based content film rate and a display refresh rate to determine a frame OFF period for a progressive video sequence.
A method, comprising the steps of:
- determining a frame OFF period for a progressive video sequence based on a film rate of film content and a display refresh rate of a display that receives a video;
- and
- inserting at least one black frame into the progressive video sequence of the video to approximate the frame OFF period.
A system, comprising:
- means for determining a frame OFF period for a progressive video sequence based on a film rate of film content and a display refresh rate of a display that receives a video;
- and
- means for inserting at least one black frame into the progressive video sequence of the video to approximate the frame OFF period.
