Abstract: A video encoder, a video decoder and a video system are provided. The video encoder performs a video encoding operation on a first video frame stream to generate an encoded stream to the video decoder, wherein the encoded stream contains deblocking filtering information. The video decoder performs a video decoding operation on the encoded stream to generate a second video frame stream. The video decoder determines whether to forcibly perform a deblocking filtering operation on a current block of a current frame of the second video frame stream according to the deblocking filtering information.

Abstract: A video encoding apparatus and a video encoding method are provided. The video encoding apparatus includes an integer-pel motion estimation (IME) circuit, a temporal noise reduction (TNR) circuit, a fractional-pel motion estimation (FME) circuit and an encoding circuit. The IME circuit provides the first motion vector, the error value and the co-located error value of the current block in the current frame to the TNR circuit. By using the first motion vector, the error value and the co-located error value of the current block in the current frame, the TNR circuit performs the temporal filtering process on the current block in an original image data to produce a denoised image data to the FME circuit.
