On Dec. 9, a Chinese court ruled that ByteDance-owned short video platform Douyin should immediately stop using the “Ultra 4K” logo when broadcasting FIFA World Cup matches on its platform, after it was sued by China Mobile’s video streaming subsidiary Migu. The case against TikTok’s sister app arose after Migu claimed it had an exclusive license to broadcast the games in ultra-high definition. A person in charge of legal affairs at Douyin told Chinese media outlet Yicai that Douyin’s contract gives it ownership of the ultra-high definition signals provided by China Media Group, the parent company of China Central Television, which has exclusive broadcast rights to the World Cup in China. This claim was disputed by Migu, which has been charging its customers a fee to watch World Cup matches in the format, while Douyin has provided 4K ultra-HD streams for free. Migu’s court filing claimed “huge losses” from “unfair competition” because of the move. Douyin Group is reportedly preparing to appeal the decision. [Yicai, in Chinese]
