Profile for frame rate conversion
First Claim
1. A method, comprising:
- detecting one or more dropped video frames in a plurality of video frames of a video stream rendered according to a first frame rate;
estimating a quality of the plurality of rendered video frames according to information about the one or more dropped video frames;
determining to switch to a second frame rate according to the estimated quality of the plurality of rendered video frames, wherein the second frame rate is achieved by inserting frames into the video stream;
detecting motion in a video frame of the video stream subsequent to the plurality of video frames of the video stream; and
switching to the second frame rate at a time determined by the motion detected in the subsequent video frame.

Abstract
The present application relates to a method for frame rate conversion. The present application relates also to a system for frame rate conversion and a computer comprising said frame rate. In addition, the present application relates to a computer readable medium having a computer program for performing said method. The method comprises defining a first frame rate profile with a first frame rate, defining at least a second frame rate profile with a second frame rate, rendering video frames at the first frame rate profile, detecting the quality of the rendered video frames, and switching from the first frame rate profile to the second frame rate profile at least depending on the detected quality of the rendered video frames.

10. A system, comprising:
-
a frame rate converter configured to switch from a first frame rate to a second frame rate according to a detected quality of a plurality of rendered video frames, wherein a timing of the switch is according to motion detected in a video frame subsequent to the plurality of rendered video frames, and wherein the second frame rate is achieved by inserting frames into the video stream, and wherein the quality of the plurality of rendered video frames is detected according to information about one or more dropped video frames. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
