Scientist in Saarbrücken are transmitting internet TV in much higher quality than usual
More and more customers are using the internet to watch movies, TV series or live sport broadcasts on their local TV. Unlike TV transmissions via antenna cable or satellite, the internet does not guarantee, that the consumer will receive data in high quality. The culprit is the so-called transport protocol on the internet, which controls the data transfer. Originally it was designed for text and images only and is therefore just suitable to a limited extend for complex multimedia data. Researchers in Saarbrücken have developed their own transport protocol which allows them to predict the picture quality that the customer will receive.

It takes into account the particular structures of different networks, ranging from broadband to mobile. Together with the Intel Visual Computing Institute and Saarland University, the researchers will present their results from 1 to 5 March at the CeBIT computer Fair in Hannover (hall 9, B43).
The current structure of the internet originates from a time when you just exchanged texts and images between computers. For this purpose the TCP/IP was created, which still regulates the data transfer on the internet.
