Abstract
A system and method that convert a video source from a first rate to a second rate. The system may have as an input a video that may be frame-based or field-based at a first rate, and convert the input video to an output video that may be frame-based or field-based at a second rate. The first rate may be 50 Hz and the second rate may be 60 Hz. Converting from the first rate to the second rate may comprise repeating frames or fields. For example, when converting from a frame-based 50 Hz input video to a frame-based 60 Hz output video, the output video comprises frames where every sixth frame is a repeated version of the preceding frame.
Claims26
A system that converts a video source from a first rate to a second rate, the system comprising:
- a first processing circuitry that receives an input video at a first rate, wherein the input video comprises frames or fields;
- a second processing circuitry that reproduces the input video as an output video at a second rate, wherein the output video comprises frames or fields;
- and
- wherein the second processing circuitry repeats the input video frames or fields to convert from the first rate to the second rate.
A method that converts a video source from a first rate to a second rate, the method comprising:
- receiving an input video at a first rate, wherein the input video comprises frames or fields;
- reproducing the input video as an output video at a second rate, wherein the output video comprises frames or fields;
- and
- wherein the reproducing comprises repeating the input video frames or fields to convert from the first rate to the second rate.
