摘要： A media delivery system simultaneously delivers a media asset stream (201) for normal play-out and a trick play stream (202) for the fast forward and rewind modes. The trick play stream (202) is a content-based summary of said media asset stream (201) instead of a dropped frame version of the media asset stream.

摘要： The present invention relates to an interactive digital television broadcast system that comprises a broadcast operator adapted to send towards a plurality of subscriber units a downstream digital broadcast stream, which is received from an interactive digital television provider. The digital broadcast stream is displayed at the plurality of subscriber units. The interactive digital television broadcast system further comprises an interaction return channel operator for providing interactivity between the plurality of subscriber units and the interactive digital television provider by means of a bi-directional interaction return channel. The system further comprises a content injection module for injecting content provided by subscriber units of the plurality of subscriber units in displayed content of a subscriber unit of the plurality of subscriber units and a shared content retrieving module for retrieving references of content shared by subscriber units of the plurality of subscriber units together with meta-data of the shared content. The system further comprises a shared content-matching module for determining relevant content from the content shared by the subscriber units of the plurality of subscriber units by matching the meta-data of the content shared with at least one predetermined criterion and a content suggestion module for suggesting to the subscriber unit to inject the relevant content in the content displayed at the subscriber unit.
