TDF and France TV test and broadcast DTT in UHD quality

TDF and France Télévisions, in a joint innovation initiative, are preparing for the Digital Terrestrial Television (DTT) of tomorrow by launching two major experiments on the occasion of the 2023 French Tennis Open:

• DTT broadcasting in UHD quality in Paris, Toulouse and Nantes on three dedicated channels, so that viewers can experience this major sporting event in 4K ; 
• experimental 5G broadcast from the Eiffel Tower, with mobile reception tests on smartphones within the tournament grounds, to prepare for the nomadic DTT of tomorrow.

Tomorrow, DTT will also be nomadic with the 5G Broadcast technology that TDF and France Télévisions are experimenting with.

During the tournament, France Télévisions' programs will be broadcast by TDF using 5G Broadcast technology: mobile reception tests will be carried out inside the stadium. This full-scale experiment carried out by TDF, in partnership with France Télévisions and with the support of Ateme, Qualcomm and Rohde & Schwarz, prefigures the future of "nomadic" Digital Terrestrial Television, which in four or five years' time will enable people to watch linear television on their smartphones, free of charge, live and outdoors.

This experiment is made possible because TDF has just obtained authorization from the French Audiovisual and Digital Communication Regulatory Authority (ARCOM) to experiment with broadcasting France Télévisions' audiovisual content from the Eiffel Tower using 5G "Broadcast" technology. This innovation means that DTT can be received outdoors, i.e. from a 5G Broadcast-compatible smartphone, without the need for a cell phone subscription or Wi-Fi.

In addition to the advantage of being able to watch programs on the move, mobile DTT benefits from all the advantages of fixed DTT:

• Free: TV reception is SIM-free, with free access and at no cost;
• Quality: low latency and constant signal flow guarantee comfort and qualitý of television viewing ;
• Complementarity: nomadic DTT coexists with traditional DTT received in homes, in the frequency plan managed́, planned and allocated by ARCOM ;
• Fluidity: 5G Broadcast ensures smooth, uninterrupted TV reception, even in the event of massive use by many viewers, in the same place and at the same time, (with no wastage or risk of congestion, linked to streaming peaks on mobile networks).
• Energy footprint : the ecological impact of DTT is lower than that of Internet and mobile networks, which route video streams through data servers.

As of today, DTT UHD 4K allows you to enjoy exceptional image quality to experience the French Open tennis tournament on three channels dedicated to 4K broadcasting.

Viewers, who increasingly want to experience major sporting events live and intensely on the big screen, benefit from exceptional picture and sound quality.

At France Télévisions' request, TDF is once again setting up 4K UHD and DVB-T2/HEVC broadcasts of the French Grand Slam tournament for Paris and the surrounding region, as well as for Toulouse and Nantes on DTT channels 81, 82 and 83.

UHD 4K(Ultra High Definition) brings even better, sharper picture quality to DTT. In particular, movements and slow motion are more fluid and realistic:

• Exceptional resolution of over 8 million pixels (3840 x 2160), four times better than standard HDTV (1920 x 1080), already available on DTT (channels 81, 82 and 83).
• Better contrast between whites and blacks with more nuances thanks to the extended luminous dynamic range and more vivid, nuanced colors (HDR: channels 81 and 83) ;
• More immersive Dolby AC-4 sound (Channel 81).

Karim El Naggar, Managing Director of the TDF Group's Audiovisual and Networks BU, comments: "DTT is a television broadcasting method that is free for the viewer, more ecological and accessible to everyone, everywhere in France. It is also a technology of the future around which TDF is constantly innovating. The experiment we're running in partnership with France Télévisions is a good illustration of the modernity of DTT. Today, viewers experience tennis matches live, more intensely and on a larger screen, thanks to the exceptional quality of 4K UHD images. Tomorrow, thanks to the tests we are carrying out on nomadic DTT, viewers will also be able to watch TV on their smartphones, on the move, free of charge, without Wi-Fi and without using up their mobile package. TDF is actively contributing to the modernization of DTT in order to meet, along with the channels, the expectations of French viewers and the new ways in which television is used and consumed".
