Problems solved by technology

[0006] However, data compression and frame rate conversion operations are often performed independently, which is a waste of resources and requires a large chip area to duplicate the motion estimation circuit and motion compensation circuit

Embodiment Construction

[0021] Certain terms are used in the description and claims to refer to particular elements. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. "Includes" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" herein includes any direct and indirect means of electrical connection. Therefore, if it is described that the first device is coupled to the second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection means.

Abstract

A video processing apparatus includes a storage interface and a video processing method, where information and hardware of a motion estimation module and a motion compensation module are shared between frame rate conversion and video coding operations. The video processing apparatus therefore may perform both the frame rate conversion and video coding operations at the same time or perform them by turns, while requiring fewer resources and a smaller chip area than conventional methods.

Description

technical field [0001] The present invention relates to a joint system for frame rate conversion and video compression, and in particular to a motion estimation module that can share between frame rate conversion and video compression And a system of processes of the motion compensation module. Background technique [0002] Please refer to FIG. 1 . FIG. 1 is a block diagram of a motion estimation / compensation (ME / MC) frame rate conversion circuit 100 in the prior art. The frame rate conversion circuit 100 converts a movie or animation source (animated source) with a sample rate of 24-30 Hz into a playback video stream (video stream) with a sample rate of 50-60 Hz or 100-120 Hz. It includes a motion estimation circuit 110 , a motion compensation circuit 120 and a Dynamic Random Access Memory (DRAM) 130 . The DRAM 130 temporarily stores the input frame, and the motion estimation circuit 110 fetches two frames (a current frame and a previous frame) from the DRAM 130 and compa...
