在《互联网电视业务技术要求》文件中,提到“互联网电视应用启动时间宜小于 3s,应不大于 5 s”。互联网电视应用的启动广告时间应包含在互联网电视应用启动时间内。 Havana, Oct 20 (UNI) Cuban Foreign Minister Bruno Rodriguez called on the US government to lift its decades-long trade embargo, or blockade, against the country.
"The US blockade has caused Cuba losses valued at 3.806 billion US dollars between August 2021 and February 2022," Rodriguez told a press conference in the country's capital Havana on Wednesday.
The call comes ahead of the Cuban government's annual submission to the UN General Assembly of a draft resolution calling for an end to the embargo. The General Assembly is scheduled to discuss and vote on the draft resolution in early November.
US trade sanctions, Rodriguez said, severely limit Cuba's access to food, medicine, technology and inputs on the international market.
"The world would be a better place without the US blockade against Cuba," he added.
First imposed in 1962, the embargo was broadened by former US President Donald Trump, who put in place 243 more sanctions, including banning all flights from the United States to Cuban destinations except for Havana, and capping remittances Cuban Americans can send to their families back home.
The current US administration allowed airlines to resume flights to other Cuban cities and lifted the cap on remittances, but the web of sanctions against Cuba remains largely in place.
For 29 times in a row, the UN General Assembly has voted in favor of the resolution urging the United States to end its embargo against Cuba.
