Viewport-based 360-degree video delivery is a typical method to reduce video traffic for virtual reality (VR) applications. However, viewport-based solutions cause key issues in multi-user VR applications, including high video traffic due to redundan

It is important to economize the infrastructure of the access network and enhance its profitability because it represents the greatest part of network infrastructure cost. As 10G-EPON can be cost-effectively shared among various access services, it i

We achieve 3-bit retransmission of 12ch multiplexed 16APSK broadcast satellite signals having extremely wideband, 38.36 MHz/ch, for 4K/8K-UHD using a DRoF-based video distribution system with new compression technique that offers a 40% cut in the tra

We successfully demonstrate a 41.3-km-reach and 128-split 10G-EPON system with dual-rate semiconductor optical amplifier on a commercial access network infrastructure. It uses N:1 optical subscriber unit (OSU) protection in order to improve system re

We propose a simple and cost effective DRoF-based optical video transmission system. Experiments on actual multiple terrestrial broadcasting signals verify the feasibility of the system and its new rate reduction method.

We propose a new access network architecture named Cloud-based PON. It separates the C-Plane/D-Plane functions of PON-OLT and consolidates the former in a datacenter. We identify the increase in upstream delay (due to the increase in Round Trip Time)

We propose a novel digitized radio-over-fiber (DRoF)-based optical video re-transmission system. This system digitally transmits radio frequency (RF) broadcast signals via the communication network (NW) while maintaining the existing RF interface at
