Satellite direct broadcasting system of the events become an essential part of everyday life, so the communication companies make the maximum effort (for reasons of competitive business) to secure the signal transduction from the source to the receiving single stations in the terrestrial homes.

In this research were selected important event for the world in general and Iraqis especially as the World Football Cup 2014 in Brazil, where the spatial dimension of this country, which is located in the south of the continent of South America i.e., in the southern half of the globe, has led to most countries in Asia and Europe in the Northern Hemisphere, including our country Iraq, will suffer from long distance, therefore discussed the technical side to transmit the signal from Brazil to Iraq, which starts from the terrestrial source (fields studio) to the earth station and then to the Brazilian satellite (Amazon-2) and then to the satellite that is responsible to cover the Middle East (Nilesat), and finally to the Earth home stations in Iraq, based on determining the length of this path was calculated two important elements affecting the transfer process, namely the path loss and the delay time by using laws of satellite communication, taking into consideration the latitude, longitude and the geographical location of earth stations, satellites, sending, receiving.

The results were important and fruitful, as it defines power and the nature of the signal for receiver side.
