The Commercial Manager of IF Telecom, José Roberto Elias, shares his experience with advanced transmitting antennas for TV 3.0. He speaks about technical characteristics necessary to guarantee quality in distribution of large quantity of content.

In this video, our international guest is Ryo Kurata, from Sales Department of EIDEN Co. Ltd.. He will speak about the MMT – MPEG Media Transport technology, used in Japan for the transport of layers in TV 3.0.

In this video, Joonyoung Park, Vice-President and Partner of Digicap, Adrian Murtaza, Senior Manager of Standardization and Business Development of Frounhofer ISS, and Jason Justman, Engineer of ONE Media/Sincalir, are our guests to speak about distribution chain and th benefits of the technology behind the new generation of TV, the ATSC 3.0

S. Korea is the country where all-IP based ATSC 3.0 terrestrial broadcasting (since 2017) and commercial 5G-based mobile broadband (since 2019) services are commercialized. Broadcasting and broadband technologies have unique pros and cons, such as coverage, QoS, cost, etc. so that convergence of them can offer new services: scalable 8K-UHD, seamless switch in a device, and broadcasting offload, etc.

Professor and PhD Jian Song, Director fo Tsinghua DTV Technology R&D Center, speaks about the efficiency of the sliding window decoding method, which can reduce the complexity of SG-LDPC codes in transmission systems.

STRL has contributed to the development of a variety of broadcast technologies, including satellite broadcasting, HDTV, digital broadcasting, and Super Hi-Vision. In the three fiscal years from 2018 through 2020, we will move forward with our R&D efforts to create new broadcast technologies and the other services in main themes of “reality imaging,” “connected media” and “smart production” with goals for 2020, and beyond that for around 2030 to 2040.

The development of new technologies allowed television systems to evolve over time. For the transport layer, the Movie Pictures Expert Group (MPEG) developed several standards to deliver multimedia content, including the MPEG-2 Transport Stream (TS), which has been widely explored for years. However, it was developed before the spread of the internet, which led to the interest in a new standard that could fulfill the needs from a connected world. One of these standards is the MPEG Multimedia Transport (MMT), which has inherited some features from the MPEG-2 TS, adapting them to be compatible with the Internet Protocol (IP). The broadband systems also needed a new standard compatible with Hypertext Transfer Protocol (HTTP), resulting in the development of the MPEG-Dynamic Adaptive Streaming over HTTP (DASH). To deliver DASH on broadcast channels, it was combined with the Real-time Object delivery over Unidirectional Transport (ROUTE) protocol. The Advanced Television Systems Committee 3.0 (ATSC 3.0) adopted many technologies to attend the requirements for the next generation of television systems, including both MMT and ROUTE/DASH. This paper presents a historic background of these delivery methods, as well as a brief technical review, focusing on a practical setup to test the methods mentioned, analyzing the differences and similarities of their properties.

This work presents recent applications of digital radio links in HF in Brazil, describing the current challenges for the development of telecommunication systems in the HF band (Rafael Diniz, Mylene C. Q. Farias)

Discrete events applied to an OFDM system were implemented, with DPQSK modulation and Rayleigh multipath, through a pre-coding process of bits in the signal before the modulation step. Using the Simulink of the MATLAB software is brought to a different approach realized in the discrete domain showing better computational performance more than 93% associated with memory utilization consistent with the compression of the digital information.
