As broadcasting environments change rapidly to digital, user requirements for next-generation services that surpass the current HDTV service quality become more demanding. The next-generation of broadcasting services will change from HD to UHD and from 5.1 channel audio to more than 10 audio channels, including a height channel for a high quality realistic broadcasting service. In accordance with the estimated trends of future broadcasting services, we propose a 10.2 channel audio format for a Korean UHDTV broadcasting service. It can create almost similar spatial sound images as 22.2 channel audio with half the number of speakers. In this paper, we propose a 10.2 channel audio acquisition system for the creation of UHDTV content, and measurements and preliminary evaluation are carried out to determine whether the performance is acceptable for broadcasting.
