Embodiment Construction

[0066] figure 2 A video encoder according to an embodiment of the present invention is shown, in particular a video encoder 200 for predictively encoding a video stream of a subsequent frame into an encoded video bit stream according to motion compensation.

[0067] The video encoder 200 notably includes a frame buffer 207 , an inter prediction unit 210 and a sharpening filter 211 .

[0068] The frame buffer 207 is used for storing at least one reference frame or image of the video stream. The reference frame is different from a current frame of the video stream. In particular, in the context of the present invention, a current frame is a frame of the currently encoded video stream and a reference frame is a frame of the video stream that has already been encoded. The "frame" mentioned below can be replaced by "image".

[0069] The inter-frame prediction unit 210 is configured to generate a prediction block of a current block of a current frame according to a reference blo...

Abstract

The present invention relates to a video encoder for predictively encoding a video stream of subsequent frames into an encoded video bit stream according to motion compensation, comprising: a frame buffer (207) for storing at least one reference frame of said video stream, The reference frame is different from the current frame of the video stream; an inter-frame prediction unit (210), configured to generate a prediction block of a current block of the current frame according to a reference block of the reference frame; and a sharpening filter ( 211), used to filter the prediction block.

Description

technical field [0001] The present invention relates generally to the field of video processing and video motion compensation apparatus, and in particular to video encoders and video decoders for supporting motion compensation for predicting frames in video. The invention also relates to an encoding method for encoding a video stream using motion compensation; and a decoding method for decoding a video stream using motion compensation. Finally, the invention relates to a computer program with a program code to carry out the method. Background technique [0002] In the field of video processing, especially in the field of hybrid video coding and compression, inter- and intra-frame prediction and transform coding are used. These hybrid video coding techniques are used in known video compression standards such as H.261, H.263, MPEG-1, 2 and 4, H.264 / AVC or H.265 / HEVC. [0003] figure 1 A video encoder according to the prior art is shown. The video encoder 100 comprises an i...
