Inter-destination Media Synchronization for TV broadcasts
doctoral thesis
This thesis presents a study on the application of inter-destination synchronization for TV-broadcasting. Inter-destination media synchronization implies synchronizing media output at different receivers. This thesis starts by investigating differences in media output between receivers of TV broadcasts at different locations and different technologies. To do this a measurement scheme is developed using media mining techniques and the fact that differences were found to be relatively fixed between receivers. Using this tool differences ranging from 0-5s were found depending on the technology and the channel used. The second aim was to test the user experience of inter-destination synchronization in (Interactive)- TV applications. After studying related social TV literature, a user test for the specific effect in social TV was developed. The test was performed at the KU Leuven using a test-panel of 36 users. The results show that contrary to the state of understanding of social TV, the social experience has little dependency on inter-destination synchronization in the 0 to 4s range. A soccer watching experiment was performed to investigate the experience of inter-destination media synchronization when an audio link is present. The thresholds found, of when the play-out difference becomes annoying or perceptible, was comparable to the social TV use case.
