Provided are a method and an apparatus for performing scalable video decoding, wherein the method and the apparatus down-sample input video, determine the down-sampled input video as base layer video, generate prediction video for enhancement layer video by applying an up-scaling filter to the base layer video, and code the base layer video and the prediction video, wherein the up-scaling filter is a convolution filter of a deep neural network.

Apparatus and method for performing scalable video decoding

An apparatus for adaptive streaming in multiple narrowband wireless communication environment comprises a communication unit configured to perform multi-communication with a server using a TCP and an UDP, a network monitor unit configured to collect state information on each of a plurality of narrowband networks, and a parameter control unit configured to: based on the collected state information on each of the plurality of narrowband networks, select a quality of video segment to be requested and one of the TCP protocol and the UDP protocol to be used in each of the plurality of narrowband networks, or determine a data size of redundant data for data loss restoration for each of the plurality of narrowband networks.
