This paper introduces a FireFort-LDGM (FF-LDGM) code that is part of ISO/IEC 23008-10 (MMT AL-FEC codes) and its application to robust Ultra High Definition (UHD) video transmission. It is especially useful for UHD real-time video streaming because that it can easily handle contiguous streams containing over several thousand packets. Simulation results show its high error recovery performance with...
This paper propose a networked distributed storage system based on an emerging MPEG Media Transport (MMT) standard. The proposed system has high error recovery capability because of its unequal error protection of image/video components by using MMT Layer-Aware LDGM codes. Higher priority image/video components are well protected by this scheme. The decoded image/video quality is better than that...
The high definition of 4K motion pictures makes them applicable to a wide variety of purposes. The development of 4K image equipment such as cameras, displays, and playback systems has made easy viewing of 4K video possible. Video frame rates have also become higher, enabling 4K-60 fps progressive (60p) video streams to be transmitted over IP networks. However, problems remain in increasing video...
In this paper we propose a method of constructing packet-level LDGM codes that offer backward compatibility with conventional viewing devices. Our proposed method makes it possible to watch content even if the viewer does not support any FEC module. Moreover, the method also improves the coding efficiency through the combined use of packet division and interleaving methods. In general, there is a...
