METHOD AND APPARATUS FOR ALLOCATING DIFFERENTIAL BANDWIDTH FOR EACH SCREEN REGION BY USING IMAGE COMPLEXITY INFORMATION
First Claim
1. A method of receiving streaming data, the method comprising:
- requesting a server for information relating to content to differentially determine quality of a plurality of regions divided from a predetermined frame of the content, according to a network state;
among at least one segment for each region encoded with at least one quality for each of the plurality of regions, receiving a segment for each region encoded according to the quality for each region determined based on the information relating to the content from the server over a network;
generating a reconstruction image for each region by decoding the segment for each region; and
merging and rendering the reconstruction image for each region.

Abstract
Provided are a method and apparatus for allocating differential bandwidth for each screen region by using image complexity information. According to an embodiment, a method and apparatus for receiving streaming data request a server for information relating to content to differentially determine quality of a plurality of regions divided from a predetermined frame of the content according to a network state; among at least one segment for each region encoded with at least one quality for each of the plurality of regions, receive a segment for each region encoded according to the quality for each region determined based on the information relating to the content from the server over a network; generate a reconstruction image for each region by decoding the segment for each region; and merge and render the reconstruction image for each region.

10. A method of transmitting streaming data, the method comprising:
-
dividing a predetermined frame of content into a plurality of regions to differentially determine quality according to a network state; generating at least one segment for each region by performing encoding on each of the plurality of regions with at least one quality; and transmitting to a client over a network a segment for each of the encoded plurality of regions according to a quality for each region among the at least one segment for each region. - View Dependent Claims (11, 12, 13, 14)
