Document Type and Number:
WIPO Patent Application WO/2018/097466
Kind Code:
A1
Abstract:
Disclosed are a method and an apparatus for allocating differential bandwidth for each screen region by using image complexity information. According to an embodiment, a disclosed streaming data receiving method and apparatus request content-related information from a server in order to differentially determine, according to network states, the quality of a plurality of regions divided from a predetermined frame of content, receive, from the server through a network, a segment for each region encoded according to the quality for each region determined on the basis of the content-related information, among at least one segment for each region encoded with at least one quality for the respective plurality of regions decode the segment for each region so as to generate a reconstruction image for each region, and merge the reconstruction image for each region and render the same.
