Abstract

The present invention relates to a method for transreceiving media content and a device for transreceiving using same, the method comprising the following steps: configuring the media content into a plurality of representations; dividing the representations into a plurality of segments; aligning subsegments which are included in the segments; and transmitting one of the representations.

Description

technical field [0001] The present disclosure relates to methods and apparatus for sending / receiving media content via the Internet. Background technique [0002] Currently, most digital broadcasts such as terrestrial, cable, satellite, and digital multimedia broadcasting (DMB) utilize MPEG-2 Transport Stream (TS) to stream AV content. [0003] In addition, according to the recent rapid development of the Internet, multimedia services of contents have been provided using an Internet Protocol (IP) network as a main transmission network. Digital broadcasting such as stereoscopic 3D video broadcasting, ultra high definition (UHD) broadcasting, multi-viewpoint 3D video broadcasting, and holographic broadcasting is evolving toward the need to transmit an increasing amount of data. [0004] However, MPEG-2 TS having a fixed-length packet of 188 bytes may not be able to transmit content having a resolution higher than that of existing HDTVs using an IP network. Contents of the i...
