Abstract
An information-signal (e.g., video-stream of certain quality) (SB1.1, SB1.2, SB1.3, . . . ) is split into two or more (Multicast-) sub-data-streams and transmitted via different channels (CH1,CH2). Thereby, on switching over of two information-signals, seamlessly switch over to another information-signal (e.g., from SD to HD quality) is enabled (in particular at the GOP-boundary in case of video).
