North Korea has sent a delegation of athletes, cheerleaders and artists to the Winter Olympics in South Korea, but how much of the event North Koreans at home will get to see is uncertain. Restrictions on the freedom of information, and the media, in the Democratic Republic of Korea (DPRK) are the most stringent in the world, with the regime controlling all television and radio broadcasters, channels and content. Yet Pyongyang's decision to participate in the games, while also sending high-profile officials to the event, reflects not only North Korea's interest in sports as a pastime, but also an attempt to demonstrate to the world another side of the country, at least on a sporting and cultural level.

North Korean athletes are to compete in figure skating, skiing and ice hockey events. The latter will see a unified team of North and South Korean players compete together. Pyongyang's late decision to participate in the Winter Olympics has stolen the limelight ahead of the games, with both the media and the worldwide public curious to see the North Korean delegation's performance both in and out of the sporting arena. Although the regime appears keen to allow such displays of sportsmanship and unity, whether it will allow its public to view any North Korea team in defeat is another matter. The country is largely a "closed shop" to foreigners and it has proved difficult to ascertain how much of the competition will be broadcast there. Contact numbers for the North Korean Olympic Committee and the state broadcaster, Korean Central Broadcasting Committee, were either defunct or unobtainable. Jean H. Lee, a global fellow with the Wilson Center and a former correspondent who set up Associated Press' bureau in Pyongyang in 2011, told CNBC that sport was a big deal in North Korea — but she was unsure whether North Koreans would get to see any live events. "North Korea likes to have as much control as they can over what their people see. They don't like the unpredictability of live broadcasts, except for events that are completely scripted, like military parades," Lee said Thursday. "The North Koreans won't have the same kind of access to the Olympics as we do. But if their athletes do well, they will certainly be celebrating it." But that doesn't mean North Koreans are completely shut off from international sports, Lee added. "State TV airs recorded clips from international sporting events and sells DVDs of Premier League matches. That means North Koreans do get to see what it looks like outside their country to a small degree, including all the advertisements and the fans in the stands."

The perils of live broadcasting

Sports are encouraged by North Korean leader Kim Jong Un, with a dedicated state-controlled sports channel, North Korean Sport Television, launched in 2015. "Sports are very popular in North Korea, and North Koreans love to watch sports programming in their spare time, either on state TV or at the library. It's something Kim Jong Un is encouraging, especially among the younger generation," Lee said. International sports events has been broadcast before in North Korea, the International Olympic Committee (IOC) told CNBC, although it said it was still "working to enable the North Korean public broadcaster to have access to the broadcast signal." It added that it had worked with South Korean broadcaster SBS (which, in 2011, was awarded the rights to show the Olympic Games in South Korea and North Korea until 2024) "to grant the rights to the Asia Broadcasting Union (ABU) who in turn will grant them to KRT, the North Korean broadcaster, as part of their membership of the ABU."

Professor Hazel Smith, author of "North Korea: Markets and Military Rule" and an academic at the University of London, told CNBC that it wouldn't be surprising if the games were shown there but, like Lee, said the "live" element wasn't desirable for North Korea. "We can look at what they've done in past international sporting events like the World Cup and Olympics. The Sydney Olympics (in 2000) is the nearest equivalent because there too you had a joint team marching into the arena," she said. "They will very likely show some of it, the question is really whether it will be shown live," Smith said.

State censorship

There are several television channels in North Korea, but all are state-owned and cover different subject matters, from news (the only source of news comes from state news agency KCNA) to educational material and, tellingly, a dedicated sports channel. For North Korea, the possibility that a live broadcast could show criticism of the regime would be a real concern for a nation where the leadership is venerated in the media, and where criticism, corruption or failure goes unreported.

"All TV in North Korea is state TV and it's all there to support the (party) line, so there's no possibility of political criticism taking place in North Korea, anywhere, so that wouldn't, from the North Korean perspective, be something that they would want to go in front of the population," Professor Smith said. There are also radio stations in North Korea, with the medium still the most pervasive form of broadcast in the country. But all are strictly controlled by the state. Internet access is heavily restricted too, although some students can go online for their studies. In fact, freedom of information is so scarce in North Korea that the country ranks the lowest out of 180 countries listed in order of press freedom, according to Reporters without Borders' 2017 World Press Freedom Index. As with other states where the media is state-controlled, the North Korean regime views broadcasting mainly as a means through which to disseminate propaganda and to extol the benefits and might of the state.
