Abstract
Described herein are, among other things, distributed processing methods and systems for frame rate conversion. In an embodiment, a transcoding management machine manages a distributed transcoding process, creating a plurality of video segments and assigning the video segments across a set of distributed transcoding resources for frame rate conversion. The management machine typically sends a given segment to a given transcoding resource along with instructions to convert the frame rate to a specified output frame rate. In addition, the management machine can send certain transcoding assistance information that preferably facilitates the frame rate change process and helps the transcoding resource to create a more accurate output segment. Hence, in some embodiments, each transcoding resource can perform its transcode job independently, but with reference to the input segment it is responsible for transcoding and the assistance information provided by the management machine.
