Abstract: A video encoding apparatus and method are provided. The video encoding apparatus includes a video encoding circuit and a control circuit. The video encoding circuit performs a video encoding operation on a video stream to produce an encoded stream. The control circuit controls the video coding circuit to perform the video encoding operation. The control circuit dynamically sets a current frame in the video stream to at least one of a long-term reference frame, a short-term reference frame, and a non-reference frame according to at least one of a playback latency control condition and an inter-frame correlation condition. The long-term reference frame and the short-term reference frame are used as the decoding reference frame in a video decoding operation.

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.

Abstract: A video encoding apparatus and a video encoding method are provided. The video encoding apparatus comprises an encoding circuit and a region of interest (ROI) determination circuit. The encoding circuit performs a video encoding operation on an original video frame to generate an encoded video frame. The encoding information is generated by the video encoding operation during an encoding process. The ROI determination circuit reuses the encoding information generated by the video encoding operation to identify one or more ROI objects according to the initial ROI and generates one or more dynamic ROIs for tracking the one or more ROI objects within a current video frame for any one of a plurality of sequential video frames following the original video frame.
