Watch RTV1 Live Online at ArgyleTvWatch RTV1 in Serbian broadcasting from Serbia for free. Not all of the online Serbian tv channels from Serbia show all of their broadcasts online. Therefore RTV1 could go offline during the transmission of a show that it does not have the legal authority to show online. For example, if RTV1 shows professional sports, i.e. Soccer, Football, or basketball, those programs may not be seen online due to legal restrictions. Also, all movies which may be seen on RTV1 are possibly subject to the same restrictions. However, all regional programs like the Serbian news programs, are usually streamed online without interruption on RTV1.
