Abstract: Disclosed herein are a method and apparatus that adaptively perform encoding and decoding based on image quality. An encoding apparatus may determine optimal Frames Per Second (FPS) for a video and may encode the video based on the determined FPS. Further, the encoding apparatus may provide improved temporal scalability. A decoding apparatus may select a frame to be displayed from among frames of a video depending on a required minimum satisfied user ratio. Through the selection of the frame, the decoding apparatus may provide improved temporal scalability.

Abstract: An apparatus and method for measuring a delay. The apparatus for measuring a delay includes an overhead inserting unit configured to inserting a time stamp into an overhead of a multiframe to be transmitted from a first location to a second location; an overhead extracting unit configured to extract a time stamp from an overhead of a multiframe received from the second location, the time stamp including bypass delay information of the second location; and a delay measuring unit configured to measure a round trip delay between the first location and the second location using the inserted time stamp and the extracted time stamp and adjust the measured round trip delay using the extracted bypass delay information.

Abstract: A method and apparatus for image compression using a latent variable are provided. The multiple components of the latent variable may be sorted in order of importance. Through sorting, when the feature information of only some of the multiple components is used, the quality of a reconstructed image may be improved. In order to generate a latent variable, the components of which are sorted in order of importance, learning may be performed in various manners. Also, less important information may be eliminated from the latent variable, and processing, such as quantization, may be applied to the latent variable. Through elimination and processing, the amount of data for the latent variable may be reduced.

Abstract: Disclosed herein are a method and apparatus for video decoding and a method and apparatus for video encoding. A prediction block for a target block is generated by predicting the target block using a prediction network, and a reconstructed block for the target block is generated based on the prediction block and a reconstructed residual block. The prediction network includes an intra-prediction network and an inter-prediction network and uses a spatial reference block and/or a temporal reference block when it performs prediction. For learning in the prediction network, a loss function is defined, and learning in the prediction network is performed based on the loss function.
