摘要： The problem is solved by a method for broadcasting a broadcast signal, comprising generating an information signal having in time a first content up to a certain time and a second content after this time. The information signal is broadcast as a broadcast signal via a first communication link At least one first feature is being provided with respect to the second content, for example an advertisement. The second content is detected in the information signal using the at least one first feature. On detection of the second content in the information signal at least one second feature is extracted from the first content in the information signal preceding the second content. The at least one second feature is sent to a user device using a second communication link, different from the first communication link, the second communication link being faster than the first communication link
