This is functional flow of HEVC-based 3D broadcasting system and the receiver in our testbed. The process of transmission part starts with acquisition of stereoscopic 3D, and separates video and audio from the 3D, then encodes them, multiplexes them, packages them with ATSC 3.0 signal information at ATSC 3.0 G/W, and finally transmits the modulated RF signal through the transmitter antenna. The reception part demodulates and decodes the received RF signal according to conditions such as RF reception quality and display type, and displays it in mobile 2D, fixed UHD 2D, and fixed UHD 3D.

This figure illustrates HEVC-based video processing and transmission process. Right view is downsampled to HD video. Both left UHD and right HD view is HEVC-encoded and multiplexed in PLP #0 and PLP #1 and modulated and transmitted in 1 channel. There are 2 subframes. Subframe 0 has PLP #0, subframe 1 has PLP #2.

There are several field tests for infotainment. Pearl, the American broadcasting corporation, defined an ATSC 3.0 Physical layer transfer profile with three single capacity setup of at least 3 Mbps, up to 24.9 Mbps, and one setup with two capacity coverage on one channel, and Sony also defined the same Physical layer transfer profile as pear to conduct a field test at Phoenix and Santa Barbara.
Our field test was performed before on-site service in Busan, and it's the first field test selectable 3D video service with existing fixed 2D UHD and mobile 2D HD broadcasting.

ATSC 3.0, the next-generation terrestrial digital broadcasting standard, is the first broadcasting standard to enable simultaneous broadcasting and broadband service a variety of media formats on high-quality fixed and mobile devices. It is first IP integrated broadcasting standard considering broadband transmission as shown in the figure.
