Apparatus and method for frame rate preserving re-sampling or re-formatting of a video stream

摘要

An apparatus configured to match an input frame rate of a video stream with an output frame rate of an output stream, the apparatus comprising, at least one memory buffer, an output frame generator, and a threshold measurement unit, the threshold measurement unit configured to generate a control feedback, wherein the box is configured to analyze the control feedback to monitor a state of the at least one memory buffer, the threshold measurement unit further configured analyze the control feedback to regulate between two or more different settings, wherein the two or more different settings include slowing down or speeding up the output frame, wherein the two or more different settings further include slowing down or speeding up of the line rate of the output stream.

1. An apparatus for matching timing of an input video stream with timing of an output video stream, the apparatus comprising:
at least one memory buffer for receiving and storing video data at an input frame rate of the input video stream, an output frame generator coupled to the at least one memory buffer for receiving video data from the at least one memory buffer at an output frame rate, and regulating means coupled to the at least one memory buffer and the output frame generator for implementing feedback control that permits a state of the at least one memory buffer, to be monitored, and for controlling a regulation, based on said state, between two or more different timing settings to selectively slow down or speed up the output frame rate.
