System for transmitting/receiving digital realistic broadcasting based on non-realtime and method therefor

A method of transmitting non-realtime digital broadcasting data, the method comprising:

• generating, at a broadcasting transport stream (TS) generation unit, a two dimensional (2-D) transport stream (TS) for a 2-D image and an auxiliary transport stream (TS) for auxiliary data necessary for 3D content using the 2-D image;
• and
• transmitting, at a transmission unit, the generated auxiliary transport stream before a corresponding broadcasting time of the 3D content, and transmit the generated 2-D transport stream according to the corresponding broadcasting time of the 3D content,
• wherein the generated auxiliary transport stream and the generated 2-D transport stream are transmitted through at least one of a broadcasting network and an Internet, and
• wherein the transmission unit transmits a synchronizing information transport stream (TS) for synchronization by multiplexing the synchronizing information transport stream (TS) with the generated 2-D transport stream.
