Pro Television Technologies will show layered division multiplexing at 'KOBA 2017(27th Korea International Broadcast Audio & Lighting Equipment Show)' to be held at COEX from May 16th to 19th.
ProTelevision Technologies from Denmark is with absolutely no doubt leading the race on ATSC 3.0 modulation and is back at KOBA show this year with more advantages for its ATSC 3.0 customers.
2015 is the year remembered for an intense and fruitful cooperation with South Korean manufacturers, Broadcasters and authorities paving way towards the future of Broadcasting in the country with 2018 Winter Olympics transmission on UHD 4k with ATSC 3.0.
Ever since, the race has been hectic, and what a race! In 2016 ProTelevision continued cooperating with South Korea to give shape to a certain transmission mode for the country, and after the world's first successful on air SFN test together with a commercial scheduler in June 2016, the ATSC 3.0 Korean mode was released.
From summer 2016 until now, ProTelevision has, in cooperation with reference transmitter manufacturers, helped the main South Korean Broadcasters to put on air their first SFN, multiple PLP networks transmitting in 4k quality becoming the reference exciter manufacturer in the country.
Not happy just being ahead, ProTelevision Technologies has been developing the Layer Division Multiplexing functionality and is presenting it this KOBA 2017
Layered Division Multiplexing (LDM), which grew from a Cloud transmission concept is the sum of two synchronized signals (in time and frequency), which are broadcast on the same RF television channel.
For instance, it is possible to combine on the same channel a signal targeting mobile services (Upper Layer, UL), and certain dBs below UL, another signal (Lower Layer, LL), where LL could be a DVB-T2 signal or some other signal format. LDM shows then a higher spectrum efficiency than TDM and FDM techniques.
Meanwhile, KOBA2017 is run by KOREA E & EX and The Korea Broadcasting Engineers & Technicians Association and it develops the advance of Korean broadcasting culture, video, audio and light industry. Various broadcasting equipment and event, including World Media Forum, International Conference and Technology Seminar will also be run at the same time.
