中国首个成功实施4K电视5G网络传输测试：春节联欢会深圳分公司将采用_我的网站

一 |     (ECNS) -- Yingkou, a coastal city in northeast China’s Liaoning Province, has developed a global jellyfish industry chain, with its products exported to more than 30 countries and regions.    Located where the Daliao River meets the Bohai Sea, Yingkou has favorable conditions for jellyfish production, including suitable water temperatures, salinity and abundant natural feed.        The city’s jellyfish industry now supports nearly 50,000 workers across breeding, harvesting, processing and trade.    Large-scale harvesting and processing began in the late 1980s, but exports were long limited to raw materials with little brand recognition. Since 2018, the China (Yingkou) Jellyfish Festival has helped promote products and strengthen overseas market presence.    Today, Yingkou processes more than 230,000 metric tons of finished jellyfish annually, with demand shifting toward ready-to-use products for restaurants and supermarkets. Local authorities are working with research institutions to upgrade deep processing and standardize production among small-scale operators.    Since 2020, Yingkou has released 520 million jellyfish seedlings into coastal waters, generating an output-input ratio of more than 11:1 while supporting marine resource conservation and fishermen’s incomes.    (By Helen Mo, intern Liu Shuangjing)                         。1月14日，据央视新闻微博报道，1月13日，中国首例4K超高速5G网络传输测试。2019年，中央电视台春节联欢晚会深圳分公司实现了4K超高清内容的5G网络传输，这也是中国5G网络的首个4K传输。据中央电视台报道，中央电视台联合中国移动和华为公司在广东深圳成功地进行了5G网络4K电视传输测试。试验成功地实现了从中央电视台春节联欢晚会深圳分公司到中央电视台北京机房的4K特高压信号传输，以及从中央电视台分公司到深圳分公司的4K特高压北京景观信号传输。转播车展的实时信号。此后不久，央视春节联欢晚会将于今年在深圳分公司实现4K超高清内容的5G网络传输，这也是中国5G网络的首个4K传输。
