This paper analyzes delays and resource efficiency when DASH segment files are transmitted through IP-based next-generation broadcasting systems such as ATSC 3.0. DASH segment files are designed to support media content of various qualities in the DASH system. The size of a DASH segment file can vary even though they may have the same quality and playback… (More)
This paper introduces the development of the remultiplexer which multiplexes MPEG-4 stream into the digital multimedia broadcasting transmission signal. The remultiplexer also has the additional channel coding functions which are essential for mobile reception of moving pictures through the digital multimedia broadcasting signal.
In this paper, we propose a design of a gateway to provide multimedia services based on the cloud transmission (Cloud Txn) system. The proposed design to support multi-layered transmission in the Cloud Txn system is described, as well as functionalities as a gateway. Also, the test implementation based on the DVB-T2 is presented to show the current progress… (More)
Next-generation digital broadcasting system transmits the DASH segment files. Delays and inefficient use of resources are the major challenges in the transmission of DASH segment files in broadcasting systems. Because the size of DASH segment files varies even though the files have the same quality, and broadcasting systems uses the fixed resource. Delay is… (More)
