[Paper] Multiformat Transmission System Using Video Decomposition for Remote Professional Media Production

Abstract

There has been a steady increase in the use of internet protocol (IP) technology for live professional media production. In addition, development is proceeding on remote production of live programs by connecting venues and a broadcasting station via an IP network. The devices needed for this remote production are being developed as well. So far, dedicated devices for transmitting 2K, 4 K, and 8K signals have been used in live professional media production, which has led to increasingly complex production systems. We propose a multiformat transmission system that enables efficient remote production without the need for dedicated devices. The proposed method decomposes 4K and 8K videos into 2K videos in order to treat 2K, 4K, and 8K video signals in a unified format. We report a simulation that evaluated image quality of the video decomposition method and a lightweight compression and evaluated the video decomposition processing delay.
