In this paper, we propose a design of monitoring equipment that verifies 8K UHD video service provided in various forms to enable stable transmission and reception on real-time. It is implemented to be able to receive 8K video transmitted in a divided form by heterogeneous network.

In this paper, we propose encapsulation methods for free-viewpoint video streaming services. The proposed methods are more efficient for view synthesis, which is one of the essential techniques to implement free-viewpoint services. By using these methods, users can reliably receive free-viewpoint video streaming services.

Owing to the increase in consumption of multimedia content and the improvement of device capacity, user demand for high-quality content has increased. However, it is difficult to transport such large amounts of content over the existing broadcasting network with limited bandwidth. To provide high-definition broadcasting, some studies suggest methods of transporting multimedia over heterogeneous networks after encoding content hierarchically. MPEG Media Transport (MMT), standardized by Moving Picture Experts Group (MPEG), is a solution that enables large-volume media transport over heterogeneous networks such as digital broadcasting networks and packet-switched networks. In the case of delivering a scalable encoded video over different networks, synchronization of each stream is an important issue. MMT defines a synchronization scheme, but does not contain sufficient functions to implement it. In this paper, we propose a synchronization scheme for media streams that are encoded hierarchically, divided into layers, and transported over heterogeneous networks. We implement our scheme using MMT and HTTP, and experimented using three encapsulated video streams with different durations. As a result, we show that the proposed scheme can reduce the waiting time to display high-quality video, relative to Dynamic Adaptive Streaming over HTTP-Scalable Video Coding (DASH-SVC) by requesting segments of enhanced layers after calculating the transmission time. Additionally, we find out that the selection of durations have a relation to the characteristics of the video.

UHD broadcasting provides 4 to 16 times much sharper videos than that provided by HDTV, and also provides multichannel audios. MMT was suggested for the next generation multimedia delivery service to provide terrestrial UHD broadcasting steadily. However, MMT signaling protocol didn't have necessary information to transport terrestrial UHD broadcasting service efficiently now. In this paper, we propose the signaling structure including signaling table such as NIT, RRT, and SDT for the reception of terrestrial UHD broadcasting.
