Abstract: This application provides a video encoding/decoding method, a corresponding video encoding/decoding apparatus. The video encoding method includes: obtaining a to-be-encoded video; encoding the to-be-encoded video to obtain a first bitstream and a second bitstream before outputting the first and second bitstreams. The first bitstream is obtained by performing frame skipping and encoding on the to-be-encoded video, and the second bitstream is obtained by encoding video frames in a second frame sequence by using video frames in a first frame sequence as key frames. The first frame sequence includes video frames obtained by downsampling video frames in the to-be-encoded video that are encoded into the first bitstream, and the second frame sequence includes video frames obtained by downsampling video frames in the to-be-encoded video that are not encoded into the first bitstream. The technical solutions provided in this application help improve video image prediction accuracy.
Abstract: A client terminal includes a super-resolution processing section and a display control section. The super-resolution processing section 48 of the client terminal executes a super-resolution process for an inputted image on the basis of scene information indicating a feature in the image. The display control section of the client terminal outputs, to a display panel, the image having undergone the super-resolution process at the super-resolution processing section. The scene information is acquired in a process prior to a super-resolution process for a super-resolution process target image.
Abstract: Apparatuses, systems, and techniques are presented to reduce temporal lag when a dynamic event is occurring in computer generated video. In one embodiment, a first averaging algorithm is utilized to determine a display value for a pixel based at least in part on previous pixel values. Once a dynamic event is detected, a set of the previous pixel values is averaged using a second averaging algorithm. The pixel value is updated based on the first averaging of the pixel values and the second averaging of the pixel values to determine a current pixel value.
Abstract: A display apparatus is provided. The display apparatus includes a memory configured to store an input image, a display panel comprising a plurality of gate lines and a plurality of data lines, and a processor configured to control the display panel to output an entire area of a first frame of a plurality of frames included in the input image by controlling the plurality of gate lines and the plurality of data lines, and control the display panel to output a partial area of a second frame subsequent to the first frame by controlling some of the plurality of gate lines and the plurality of data lines.
Abstract: Systems, devices, and methods disclosed herein may apply a computational spatial-temporal analysis to assess pixels between temporal and/or perspective view imagery to determine imaging details that may be used to generate image data with increased signal-to-noise ratio.
Abstract: A method for encoding pictures within a groups of pictures using prediction, where a first reference picture from a group of pictures and a second reference pictures from the subsequent group of pictures are used in predicting pictures in the group of pictures associated with the first reference picture. A plurality of anchor pictures in the group of pictures associated with the first reference picture may be predicted using both the first and second reference pictures to ensure a smooth transition between different groups of pictures within a video frame.
Abstract: A method of encoding a local time base embedded in the compressed data is disclosed. The local time base is encoded in two parts. The first part has a modulo time base that indicates the specific interval in the reference time base and the second part has a time base increment relative to the reference time. Two forms of time base increment is used to allow for the possibility of different encoding order and displaying order. A mechanism for the synchronization of multiple compressed streams with local time base is also described. A time base offset mechanism is also used to allow finer granularity synchronization of the multiple compressed streams.
