Abstract: To provide an aspect-free television (TV) service that allows viewers to watch more attractive TV programs using various aspect ratios selected based on the creator's intent, we investigate the system requirements and specific transmission methods for live production in broadcast stations. We propose the use of a 16:9 active video area in conventional video signals such as HD/UHD-1 as containers, and determine the range that the user-specified aspect ratio video occupies in the container using identifier ancillary data. This method is highly compatible with existing systems and conventional workflows. Scalability using multiple containers is considered in this study.
