Bayerischer Rundfunk and Institut für Rundfunktechnik run T2 test network
Following the decision to officially deploy DVB-T2 in Germany in 2017, Bayerischer Rundfunk and the Institut für Rundfunktechnik are running a test network in Munich to assist the equipment and receiver industry with the testing of new devices. The test network is to remain available until the introduction of regular DVB-T2 services in mid-2019, according to DVB Scene eNews.
The broadcasts are taking place in a single frequency network (SFN) on channel 43 (650 MHz). The transmitters are located at the broadcast house in Munich and at its Freimann and Ismaning sites. Portable and mobile reception devices will be included in the testing program.
As part of the testing, HEVC enabled encoders and multiplexers are to be tested in laboratory service. The key aspects of the research into HEVC video coding lie in the determination of compatibility and stability of all elements of the signal chain as well as an estimation of the prospective quality level and spectrum needs.
The tests include both different settings of HEVC codecs and the transmission of various signal formats. These will tend to cover a greater range than the set of parameters selected for the subsequent introduction of DVB-T2. Therefore the parameterisations in the pilot test will not anticipate any decisions of the corresponding task groups of ARD and ZDF, but will provide the basis for a substantiated and reliable technical selection to be recommended for the subsequent regular service. Hardware and automobile manufacturers interested in the trial are invited to contact IRT.
In a separate move, DVB Member Media Broadcast has been reported to be planning its own a T2/HEVC field test in Berlin. The tests are set to take place from Autumn 2014 through Summer 2016.
